Instructions and characteristics of the sheriff alarm system. Buy a Sheriff car alarm: what should you pay attention to? Sheriff alarm description

Important!

The system has six independent (two of them are remotely controlled) functionally reprogrammable channels. These are six physical wire lines with programmable operating logic, providing flexible changes in system functions for controlling the shutdown of turbocharged engines (turbo timer), searching for a car in a parking lot, remotely turning off the system siren in “NIGHT” mode with a control channel for an additional pager or mobile communication device, security service a car with the engine running without an ignition key, control of additional devices at specified time intervals.

The interactive pager provides real reception of signals confirming the execution of a command by the system. During one security cycle, the system provides information about each triggered sensor on the LCD display of the two-way communication key fob.

To ensure the highest level of protection for your vehicle, this security system has a programmable manual override feature. In some cases, for example, when the key fob transmitter for remote control of the system is lost or does not work (or perhaps your key fob transmitter is blocked by powerful radio emissions from a jammer type device), you may need to manually arm or manually disarm the system. Read the sections “Manually arming the system” and “Manually disabling the security system,” which detail the procedures for arming and disarming the system in such a situation. In addition, this manual contains a table in one section of which the system functions are used, including the selected system shutdown method, and the optional equipment installed in the vehicle. Although the "Secret Code" function is not programmed by default (you must enter a personal code to disable the system), the Valet switch can also be selected to disable the system. See which method was programmed to shut down your system and review it in the appropriate section of this manual.

If the F13 "Secret Code" function is programmed, then writing codes for new key fobs, changing the secret code, changing the status of programmed functions from F12 to F27, emergency disarming of the system, turning off the system when triggered in Anti-Hi-Jack modes are possible only after entering the secret code! Changing the parameters of functions F1 to F11 does not require entering a secret code and is always available.

Transmitters with technology to protect digital codes from interception (Keeloq)

The key fob transmitters included with this security system use the most advanced and reliable form of radio frequency transmission of any car security system currently available. Some of today's sophisticated car thieves use devices known as code grabbers, which allow them to receive and store the signal sent by the car's remote control device. After the driver leaves, this code is used by the thief to disarm the system.

Unlike the remote control devices described above, the key fob transmitters included with your security system change the code of the transmitted signal every time the button is pressed, so when a thief plays the intercepted signal from your key fob transmitter, the security system simply will not respond to it. If the button on your transmitter key fob is pressed more than 30 times when it is outside the control of the security system (for example, children are playing with it), the system will not respond to the call from the transmitter key fob when you decide to use it again. You need to synchronize your key fob transmitter with the security system receiver. To do this, simply press the system arming/disarming button on the transmitter key fob twice within one second. After this, the system will again respond to all remote control commands.

ANTI-BIGGER ACTIVE TRANSPONDER

ANTI-BURRY ACTIVE TRANSPONDER is designed to increase the effectiveness of the protective properties of the security system, ensure the return of the car and the safety of the owner. The built-in function F14 allows you to select one of three operating modes.

F14/1 - state "off". The system eliminates the use of an active transponder.

F14/2 - first stage hidden security mode. The system detects the presence of a transponder every time the ignition is turned on, confirming with a single beep. Subsequent security actions are carried out silently in cyclic mode. Transponder in the working area - normal system operation. The transponder is outside the working area - the system includes blocking circuits. Placing (turning on) a transponder in the work area ensures the restoration of break circuits. This device operation algorithm has no time or quantitative restrictions.

F14/3 - second stage hidden security mode. The system detects the presence of a transponder, confirming with a single beep each time the ignition is turned on. Subsequent security actions are performed in the mode of switching on the blocking algorithm of the ANTI-HI-JACK type with other time parameters if the system has “lost” the transponder. Transponder in the working area - normal system operation. The transponder is outside the working area - the system starts the ANTI-HI-JACK mode. Subsequent placement (switching on) of the transponder in the work area does not ensure restoration of the break circuits. The system can be "restored" using the Valet button or by entering the Secret Code.

Manually arming the system

If for any reason you cannot use the key fob transmitter to arm the system, you can do this using the Valet button at any time, even if you do not have the ignition key.

Full system arming
  1. Briefly press, release, and then press and hold (more than 3 seconds) the VALET button until the activation of the arming mode is confirmed by an audible signal.
  2. The LED will flash quickly to indicate that the last door is waiting for the door to close:
    1. if the door was closed, the system will wait for the last door to open and then close,
    2. if a door was opened, the system will wait for the last door to close.
  3. After the last door is closed, and after 3 seconds, the full security mode will turn on.
Manual arming is performed only for one cycle before the system is disarmed.

Note After turning off the ignition, manual arming can only be performed after a 5-second delay.

Additional (emergency) call via pager signal

  • The system has an additional channel for transmitting a call/notification signal to the owner of the two-way COMMUNICATION key fob. Call control can be carried out by a second person in the car and activating the "CALL" button on the pager module. A call signal is generated when you press and hold the "CALL" button for more than 2 seconds.
  • The beepper of the two-way COMMUNICATION key fob begins to emit a frequently repeating sound signal for 5 seconds. The vibration alert is also activated for 5 seconds.
Protecting the car when the security mode is on
  • Opening the hood, trunk or door of the car will immediately trigger the system and turn on the alarm. The siren will sound and the vehicle's side lights will flash for 30 seconds. After this, the sound of the siren and the flashing of the side lights will stop and the system will continue to monitor all vehicle protection circuits. If a burglar or carjacker left the door open, the siren will sound for six 30-second cycles and then turn off; this protection zone will be isolated and the system will continue to monitor the remaining protection circuits of the vehicle.
  • Each time the system is armed, the red LED indicator installed in the vehicle's dashboard begins to flash slowly. The flashing LED indicator serves as a visual warning to potential burglars or car thieves. The indicator uses a light-emitting diode that consumes a small current, so even if the system is left in the security mode for a long time, the operation of the LED indicator will not drain the vehicle's battery.
  • Each time the system is activated, the vehicle's side lights flash for the entire 30-second alarm cycle, drawing attention to the vehicle.
  • Additional feature: every time the system is armed, the vehicle's starter circuit is blocked. In this case, the car engine cannot be started even with the ignition key.
  • When the system is armed, any strong blow to the car body or glass will trigger the shock sensor and turn on the alarm.
  • Weaker impacts will trigger the shock sensor's warning zone, causing the siren to emit a series of short warning tones.

Car protection when the security mode is on and the engine is running

  • Opening the hood, trunk or door of the car will immediately trigger the system and turn on the alarm. All blocking circuits will turn on. The siren will sound and the vehicle's side lights will flash for 30 seconds. After this, the sound of the siren and the flashing of the parking lights will stop, and the system will continue to monitor all vehicle security circuits. If a burglar or carjacker left the door open, the siren will sound for six 30-second cycles and then turn off; this protection zone will be isolated, and the system will continue to monitor the remaining protection circuits of the vehicle.
  • The LED indicator will begin to flash slowly. Each time the system is activated, the vehicle's side lights flash for the entire 30-second alarm cycle, drawing attention to the vehicle.

Passive (automatic) arming of the system

  1. Turn off the engine, get out of the car, close all doors, hood and trunk.
  2. The LED will begin to flash rapidly, indicating that the system's 30-second passive arming timer has started.
  3. After 30 seconds, the system will turn on the security mode.
  4. The vehicle's parking lights will flash once.
  5. The siren will emit one short confirmation beep.

If there is an additional door locking/unlocking circuit and programmable function F27 (door locking during automatic arming) is enabled, then the vehicle doors will be locked.

Note If the vehicle's door, hood or trunk is opened while the passive arming timer is running, the system's passive arming timer will be paused. When all doors, hood, and trunk are closed, the system will begin the passive arming cycle from the beginning. At the end of the 30-second time interval, the security mode will turn on.

Warning signals about an attempt to break into a car

If an attempt was made to break into the car in your absence, the security system will inform you about this.

When the system is disarmed, four short beeps will sound and the side lights or direction indicators will flash four times.

Sit in the car and before turning the ignition key, watch the LED indicator on the car's dashboard blink.

  • If the LED indicator blinks once after a pause, then the system was triggered by the first shock sensor or by the trigger of an additional device connected to the system.
  • If the LED indicator blinks twice after a pause, then the system was triggered by a second shock sensor or by a trigger from an additional device connected to the system.
  • If the LED indicator blinks three times after a pause, then the system was triggered by the trunk or hood limit switch (when trying to open the hood or trunk) INSTI(-), INST2(-) = INST1(-) (when INST2J-) is an additional input trigger) .
  • If the LED indicator flashes four times after a pause, then the system was triggered by the door limit switch (when trying to open the car doors) DOOR(-), DOOR(+).

Warning signals about an attempt to break into the vehicle are stored in the system memory and are erased when the ignition is turned on.

Valet Push Button Switch (VALET Mode)

The Valet push-button switch allows you to temporarily disable all security functions of this system, eliminating the need to take your system's control transmitter to a parking attendant or service station mechanic. When the system is in Valet mode, all security functions are disabled except for the Panic mode remote control function and the vehicle door remote control function.

Enabling Valet mode
  1. Disarm the system using the key fob or Valet button, or enter your personal code to manually disable the system.
  2. Turn the ignition ON and OFF.
  3. The LED indicator will light up continuously.
  4. The system is in Valet service mode.

Note. In Valet mode, each time the ignition is turned off, a short beep will sound.

Note. If the system does not confirm the entry of the secret code with an audible signal, arm the system using the transmitter key fob, then disarm the system and repeat the procedure for entering the secret code.

Anti-Hi-Jack mode (protection against car theft and hijacking)

Remote activation of the Anti-Hi-Jack Tx function using a key fob transmitter (programmable function F18).

  1. Turn on the ignition or start the engine.
  2. Simultaneously press and hold buttons 1 and 2 (see Fig. 1) until a confirmation signal appears in the form of three flashes of the side lights.
  3. Release the key fob buttons.
  4. A 20-second delay is activated.
  5. Over the next 20 seconds, the system begins to emit short beeps and periodically turn on the blocking circuits.
  6. Total: after a 40-second delay, the alarm mode is activated (sound and light alarm).
  7. All blocking circuits are constantly turned on, leading to a complete stop of the engine.

The Anti-Hi-Jack IGN function, when the ignition is turned on (programmable functions F19, F20) and the door limit switches or vehicle speed sensor is activated, works as follows:

  1. function is disabled,
  2. activated every time the ignition is turned on and the door limit switch DOOR(-) is activated in the mode: closed/open/closed or open/closed,
  3. activated every time the ignition is turned on and the door limit switch DOOR(+) is activated in the mode: closed/open/closed,
  4. is activated every time the ignition is turned on and the vehicle moves.

Note Once the alarm is turned on in Anti-Hi-Jack mode, the sound and light alarms will work until the car battery is completely discharged. Disabling the system in Anti-Hi-Jack mode is only possible using the Valet button in the mode of simply pressing the Valet button or by entering a secret code.

Disabling Anti-Hi-Jack mode

Disabling the Anti-Hi-Jack function within 40 seconds after its activation (i.e., during the warning cycle, before turning on the siren, side lights, interior lighting and engine blocking circuits) is done by pressing the Valet push-button switch once.

  • If function F13 is in Valet mode and the alarm is triggered, turn off the Anti-Hi-Jack as follows: turn off, then turn on the ignition and press the Valet button within 10 seconds.
  • If function F13 is in Secret Code mode, turn the ignition off and on again 2 times, then enter your personal secret code to disable the system.

Automatic door locking when the ignition is turned on (function F3/2)

If your vehicle is equipped with optional power door locks, this system can be programmed to automatically lock the doors when the ignition is turned on. Every time you turn on the ignition, after 3 seconds the car doors will be locked to ensure your safety. If any of the doors is open at this moment, the doors will not be locked. If you would like to enable this feature, please contact your installer or see the Programmable Features section.

Automatic door locking when the vehicle starts moving (function F3/3)

If your car is equipped with an electronic speed sensor and additional electric door locks, this system can be programmed to automatically lock the doors when the car starts moving - after 3 seconds the car doors will be locked to ensure your safety. If any of the doors is open at this moment, the doors will not be locked. If you would like to enable this feature, please contact your installer or see the Programmable Features section.

Automatic door unlocking when the ignition is turned off (function F4)

If your car has additional electric door locks, then each time you turn off the ignition, the car doors will automatically unlock. If you wish to disable this feature, contact your installer or see the Programmable Features section.

AV FUNCTION - disarming the system in two stages

Disarming the system in two stages allows you to further increase the anti-theft protection of your car against “electronic tampering” with devices like 409, etc. If the AV trigger function (F21) is enabled, arming the system with a key fob transmitter or using the Valet button will set all ARM, ARM blocking circuits to the armed state. When performing the "DISARM" operation using a transmitter key fob, the system will unlock the doors, turn off the input triggers of the doors, hood, and trunk, but will not turn off the interlock circuits. To finally unlock the system, use the Valet button or enter your Secret System Unlock Code, in which case the interlock circuits will be closed and the engine can be started.

If the TURBO TIMER function is activated, the system will delay the activation of the ARM, ARM blocking circuits for the duration of the turbo timer, ensuring engine operation without the ignition key. The engine will then be automatically turned off, all interlock circuits will be turned on and the sensor channels will be activated.

PASSIVE ENGINE LOCK (immobilizer function) with AV function

Passive engine blocking (immobilizer function) ensures automatic activation of the ARM, ARM blocking circuits 20 seconds after the ignition is turned off.

  1. Stop the engine and turn off the ignition. After 20 seconds, the LED indicator begins to flash slowly, indicating the active state of the immobilizer function.

    To disable passive engine immobilization

  2. Turn on the ignition. The system begins to confirm the active state of the immobilizer function with short-term sound signals (the engine cannot be started).
  3. Briefly press the disarm button of the key fob transmitter to turn off the blocking circuits, or press the Valet button or enter the Secret Code if the passive blocking function F17/2 is enabled.
  4. Briefly press the Valet button or enter the Secret Code to disable the ARM and ARM interlock circuits if the F17/3 passive interlock function (PDU with AV function) is enabled. In mode F17/3, it is impossible to disable passive locking from the key fob transmitter.
  • If the TURBO TIMER function is activated, the system will delay the activation of the ARM, ARM blocking circuits for the duration of the turbo timer, ensuring engine operation without the ignition key. Then the engine will be turned off automatically. Then, after 20 seconds, all blocking circuits will turn on in the PASSIVE ENGINE BLOCKING mode.
  • The passive engine blocking function is independent of the state of function F21 (AV trigger).

Remote control of additional devices (channel CH2)

This system has a CH2 channel (dark blue wire) for controlling various additional devices connected to the system. This channel can be used (programmed) for:

  • remote control of car window lifter,
  • control the security mode of a car with the engine running without an ignition key,
  • control of trigger type devices. Programmable functions TRIGGER1 (output control at any time and in any system state), TRIGGER2 (output switching on at any time when the ignition is on and in any system state, static output switching off at any time and in any system state).

To supply a control signal to an additional device via channel CH2, use key fobs-transmitters according to Table 1, Table 2 of system control commands, and also use the table of programmable functions to select the required parameters.

The CH2 output is connected to ground during the channel activation time.

Channel output CH2 is a low-current output designed to control the coil of an additional relay or an equivalent low-current load.

  • remote opening of the car trunk,
  • remote car engine start,
  • remote control of timer devices,
  • control devices at specified time intervals,

The CH3 output is connected to ground during the channel activation time. The channel is activated immediately when you press the CH3 button.

To supply a control signal to an additional device via channel CH3, use key fobs-transmitters according to Table 1, Table 2 of system control commands, and also use the table of programmable functions to select the required parameters.

The output of channel CH3 is two outputs of a normally open relay with a load current of no more than 1 A.

Note If the CH3 output was activated while the system was in armed mode, the system will simultaneously disable the shock sensor and the hood/trunk trigger so that opening the trunk does not trigger the system. After the trunk is closed, the system will automatically protect this circuit again.

Remote control of additional devices (channel CH4)

This system has a CH4 channel (green wire with a white stripe) for controlling various additional devices connected to the system. This channel can be used (programmed) for:

  • remote control of timer devices,
  • pulse output of negative polarity for 1/10/20/30 sec when arming the system: (use option - as an output for controlling power windows, electric sunroof, etc.),
  • Pulse output of negative polarity for 20 seconds when the system is disarmed (use option - polite backlight control output). Turning the ignition on will cancel the pulse at any time.

The CH4 output is connected to ground during the channel activation time.

Channel output CH4 is a low-current output designed to control the coil of an additional relay or an equivalent low-current load.

Remote control of additional devices (ARM channel)

  • pulse output of negative polarity for 20 seconds when the system is disarmed (use option - polite backlight control output). Turning the ignition on will cancel the pulse at any time,
  • control of shutdown of turbocharged engines or other automatic equipment,
  • W-TRIGGER - launch and reset of a channel via radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes),
  • W-impulse 1 sec - launching a channel via a radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes),
  • W-impulses 1 /0.5/1 sec - launching a channel via a radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes).

Note To enable or disable control of the CH6 channel in the “W-functions” mode, press and release the combination of buttons F(5)+ 4.

  • Control is allowed - "SET" - indicator on the LCD.
  • Control is prohibited - there is no "SET" indicator on the LCD.

The CH6 output is connected to ground during the channel activation time.

The output of channel CH6 is two outputs of a normally open relay with a load current of no more than 1 A.

Note If the CH6 channel output was activated while the system was in security mode, the system will simultaneously turn off the shock sensor for a while so that opening the trunk does not trigger the system. After the trunk is closed, the system will automatically protect this circuit again.

Turbo timer function

The turbo timer function can be activated on the ARM and CH6 physical lines by programming functions F22/2 and F24/3. The lines are activated by turning the ignition key to the “IGNITION ON” position and remain in this state indefinitely as long as the ignition is on. TURNING OFF THE IGNITION leads to the activation of the line deactivation delay timer, programmed by the F1 function (for 1/2/3/10/30 minutes). Thus, after the time specified in F1 has expired, the turbo timer lines will go into an inactive state.

It is possible to urgently disable the turbo timer only using the key fob transmitter at any time.

Resetting the ACTIVE STATE of the turbo timer
  1. Remove the key from the vehicle's ignition.
  2. Within 1 second, press button 3 twice (Fig. 1).
  3. The system must confirm receipt of the command with two short beeps and one short light signal, then reset the turbo timer channel.

Programming codes for new transmitters and transponders

Please note that when programming a new transmitter into the system's memory, all previously programmed transmitter codes are erased, so when programming additional transmitters, existing transmitters must be re-programmed.

Attention!

Since the transmitters use a constantly changing (dynamic) code, in some situations (for example, when pressing the key fob buttons more than 30 times outside the system's coverage area), desynchronization of the key fobs and the system may occur. In this case, go to the car and within one second press button 1 (Fig. 1, Fig. 2) of the transmitter twice. Synchronization will be restored, and the key fob will again be able to control the system.

Transmitter programming

Recording codes for new transmitters (F13 - "Valet" state).

Attention!

Remember that each operation must be performed within 5 seconds after the previous operation. If the 5 second interval is exceeded, the system will automatically exit programming mode, which will be confirmed by one short and one long beep from the siren. If the ignition was turned off during programming, the system will immediately exit the programming mode, confirming this with one short and one long siren signal.

  1. Disarm the system, get into the car and turn on the ignition.
  2. Press the Valet pushbutton switch 3 times. You will hear one siren sound to confirm that the system is ready to program new transmitters. Press and hold button 1 (Fig. 1) of the first transmitter until you hear a long siren signal confirming that the programming of the first transmitter is completed (the transmitter channels will be programmed automatically). The LED will begin to flash slowly.
  3. Press and hold button 1 (Figure 1) of the second transmitter until you hear a long siren signal confirming that programming of the second transmitter is complete. The LED will begin to flash slowly.
  4. Repeat step 3 for the remaining transmitters.
  5. To exit transmitter programming mode:
    1. turn off the ignition or
    2. wait 8 seconds without performing any actions.

You will hear one short and one long beep to confirm that you have exited transmitter programming mode, and the system LED will turn off.

Recording codes for new transmitters (F13 - Secret code status)
  1. Disarm the system using a key fob or by entering the Secret Code with the "Valet" button, i.e.
    1. turn on, turn off and then turn on the ignition,
    2. using the Valet switch, enter the first digit of the code (the number of presses of the Valet button corresponds to one digit of the code),
    3. using the Valet switch, enter the second digit of the code (the number of times the Valet button is pressed corresponds to the second digit of the code),
  2. Press the Valet pushbutton switch 3 times. You will hear one long siren signal.
  3. Press button 1 (Fig. 1, Fig. 2) of the first key fob transmitter. The system will confirm the recording of the new key fob code into memory with a sound signal.
  4. Press button 1 (Fig. 1, Fig. 2) of the second transmitter key fob. The system will confirm the recording of the new key fob code into memory with a sound signal.
  5. To record the code of an active anti-robbery transponder, turn on (or turn off and then on) its power. The system will confirm the code recording with a sound signal.

Attention!

Remember that each operation of writing the codes of new key fobs deletes the codes of old key fobs from memory and must be performed for all key fobs at once. The system maintains up to four key fob codes in memory, regardless of whether the codes are from four different key fobs or the same code is written into the system four times.

Operating modes of the LED indicator of the LED system installed in the car dashboard

Short confirmation signals given by the system siren

Operating modes of vehicle side lights

Note

If the alarm went off in your absence, then when you disarm the system, I will call you! chat four short beeps and the parking lights or direction indicators will flash four times, and the LED indicator will flash according to the code that corresponds to the zone that was activated in your absence.

Before starting your car, watch the LED indicator on your car's dashboard blink. The number of flashes of the LED indicator indicates the zone protected by the system that triggered the SHERIFF 900 car alarm in your absence. For more information, see the "Vehicle Intrusion Warning Signals" section of this manual.

An attempt to disarm the system after the system has been triggered (the alarm siren has turned on) will only result in the audible alarm being turned off. The system will not be disarmed. In order to disarm the system, you must press the arm/disarm button on the key fob transmitter when the system does not sound an alarm.

Replacing batteries

A small red LED is installed in the transmitter housing, which confirms that the transmitter buttons have been pressed and also indicates the battery status. As the battery drains, you may notice a decrease in the transmitter's range. To replace the battery

  1. open the cover by unscrewing the small screw on the back of the transmitter housing,
  2. remove the dead battery, remember its polarity and dispose of it properly,
  3. install a new battery (type GP23A), make sure the polarity is correct,
  4. Carefully install the cover without damaging the LED or switches on the circuit board, and tighten the small screw on the back of the transmitter housing.

INSTALLING THE SYSTEM

Installation of the main components of the SHERIFF ZX 900 alarm system

Connecting system wires

ATTENTION!

When connecting additional relays to the security system outputs, make sure that there is a damping diode on the relay control contacts. Connect the output of the SHERIFF ZX 900 car security alarm to the additional relay only from the anode side of the damping diode. Make all connections to the security system wires only with the fuses of the power supply circuits of the SHERIFF ZX 900 security system removed. If there is no damping diode as part of the additional relay, the polarity of its connection is arbitrary.

Warning

Direct connection of low-current channel outputs to the high-current executive input of the car trunk lock opening circuit, as well as to the input of some remote vehicle engine start devices, will damage the main unit of the security system.

Trunk release control

Connect the selected control channel wire to the control contact of an AS-9256 type relay (or equivalent 30A automotive relay). Connect the wires to the other relay contacts according to your control circuit. A diagram of the approximate use of channel 2 to control the trunk opening is shown below:


Standard car door locking/unlocking configurations

Three-wire negative door unlock/lock circuit

When installing the SHERIFF ZX 900 car alarm in such cars, the dark green and dark blue wires for locking/unlocking the car doors are not used.

The orange wire and the blue wire with a white stripe should be connected to ground (a metal part of the car body).

The yellow wire is the negative locking pulse output and must be connected to the control wire of the stock negative locking relay. The white wire is the negative release pulse output and must be connected to the control wire of the standard negative release relay. The control circuit for the central locking channel with negative trigger is shown below:


Three-wire door unlock/lock circuit, positive polarity

When installing the system in such vehicles, the dark green and dark blue wires for locking/unlocking the car doors are not used.

The orange wire and the blue wire with a white stripe should be connected to the +12V power supply.

The yellow wire is the positive locking pulse output and must be connected to the control wire of the standard positive locking relay. The white wire is the positive release pulse output and must be connected to the control wire of the standard positive release relay. The control circuit for the central locking channel with a positive trigger is shown below.

Five-wire door unlock/lock circuit with polarity reversal

When installing the system on such cars, it is necessary to cut the standard control wires for the electric drives of the car door locks. These wires are routed from the main lock/unlock switch to the auxiliary lock/unlock switches, and from them to the power door lock actuators.

Cut the stock locking wire and connect the yellow system wire to the end of the cut stock wire that goes to the auxiliary switches (power door locks). Connect the green wire to the end of the cut stock wire that goes to the main switch.

Cut the standard unlocking wire and connect the white system wire to the end of the cut standard wire that goes to the additional switches (power door locks). Connect the blue wire to the end of the cut stock wire that goes to the main switch.

The orange wire and the blue wire with a white stripe must be connected to a fused +12V power source.

Transmitters with technology to protect digital codes from interception (KeeLoq)

The key fob transmitters included with this security system use the most advanced and reliable form of radio frequency transmission of any car security system currently available. Some of today's sophisticated car thieves use devices known as code grabbers, which allow them to receive and store the signal sent by the car's remote control device. After the driver leaves, the thief uses this code to disarm the system.

Unlike the remote control devices described above, the key fob transmitters included with your security system change the code of the transmitted signal every time a button is pressed, so when a thief plays the intercepted signal from your key fob transmitter, the security system simply will not respond to it. If the button on your transmitter key fob is pressed more than 30 times while it is not within the security system's control (for example, if children are playing with it), the system will not respond to the key fob transmitter when you decide to use it again. You need to synchronize your key fob transmitter with the security system receiver. To do this, simply press the system arming/disarming button on the transmitter key fob twice within one second. After this, the system will again respond to all remote control commands.

INSTALLING THE SYSTEM

INSTALLING THE MAIN COMPONENTS OF THE SHERIFF APS-2500 SYSTEM

Main unit (control module)

Select a location in the passenger compartment to install the main system unit (behind the vehicle's dashboard) and secure the unit with two screws. The main unit of the system can be secured using cable ties.

Never install the main unit of the system in the engine compartment of a car because the housing of this module is not sealed. You should avoid installing this unit directly on the standard electronic components of the car. Vehicle electronic components may cause radio frequency interference, which in turn may reduce the operating distance of the system's transmitter or cause interruptions in system operation.

Siren

To install the siren, select a place in the engine compartment where the siren will be protected from access from the bottom or front wheel arches of the vehicle. The location in the engine compartment selected for installation of the siren should not contain hot or moving parts. The siren should be pointed downward to prevent water from accumulating in it, and the bell should be directed outward from the engine compartment to maximize sound propagation. Fix the siren in the selected location on a special bracket using screws.

Hood or trunk limit switch

The limit switch included with this system is designed to protect the trunk (rear door on hatchback or station wagon) or hood areas of the vehicle. In any case, the limit switch should be mounted on a metal surface electrically connected to the vehicle ground. It is very important to install the limit switch in a place where water does not leak or accumulate. Never install a limit switch in the drains that are located on the car's fenders along the hood and trunk. To install the limit switch, choose a place protected by a rubber seal when the hood or trunk lid is closed.

The limit switch can be installed using the included bracket or directly into a 6 mm (1/4 inch) diameter hole drilled into the vehicle body. In any case, the limit switch must be installed in such a way that the hood or trunk lid, when closing, presses the limit switch and moves its moving contact by at least 6 mm, and when opening, allows the moving contact to rise completely.

LED indicator installed in the car dashboard

This system comes with a small red LED indicator that shows the status of the security system and is a visual warning to potential burglars and car thieves. The LED indicator must be installed in the car's dashboard in a place where it can be clearly visible both from the driver's seat and from the outside through the car windows. Before drilling a hole in the selected location on the dashboard, inspect it from all sides so as not to damage the car’s standard electrical wiring with the drill and make sure that the LED indicator wires can be connected to this location.

Carefully drill a 6 mm (1/4 inch) hole in the selected location and pass the red and blue LED wires through the hole on the face of the panel. Press down on the LED and install it firmly into the mounting hole.

Valet switch

To install the switch Valet choose a place where the car driver can easily use it. There is no need to carefully hide the switch, but it is still recommended to use certain disguise methods, because this will increase the level of system security and make it more difficult for hijackers.

Push button switch Valet Can be mounted on the car dashboard from below on the driver's side. You must make sure that when you later install the system, you can easily connect the wires to the switch.

Shock sensor

To install the impact sensor, select a flat, hard surface on the partition separating the engine compartment and the vehicle interior, on the passenger side. Attach the shock sensor to the selected location using the two self-tapping screws included with the system. The sensor can be mounted on the posts to which the vehicle's dashboard is attached using cable ties.

Regardless of which method of mounting the shock sensor is used, it is necessary to ensure easy access to the potentiometer for adjusting the sensitivity of the sensor, which may need to be used when later configuring the system.

CONNECTING THE WIRES OF THE SHERIFF APS-2500 SYSTEM

ATTENTION! When connecting additional relays to the security system outputs, make sure that there is a damping diode on the relay control contacts. Connect the security system output to the additional relay only from the anode side of the snubber diode. Make all connections to the security system wires only with the security system power circuit fuses removed.

Large 12-pin system connector

White wire:+12 V pulse output for connecting vehicle side lights (maximum current 15 A). The white wire in the system block is designed to supply a +12 V pulse signal to the power supply circuit for the vehicle’s side lights. Connect these wires to the positive polarity wires of the vehicle's side lights circuits.

Red wire protected by 15 A fuse: constant power supply + 12 V. This wire is used to power the built-in power circuits - controlling the side lights of the car.

Red wire with white stripe, protected by a 5 A fuse: constant power supply +12 V. This wire is used to power all main circuits of the system.

White wire with black stripe: siren power supply output (+12 V). Route this wire through the hole with a rubber bushing, which is located in the partition between the engine compartment and the car interior, to the place where the siren is installed. Connect the white wire with the black stripe to the red wire of the siren (+12V power supply). Connect the black wire coming from the siren to ground (a metal part of the car body).

Black wire: power supply input (ground). Connect the black wire to ground (a metal part of the car body). Do not confuse this wire with the thin black antenna wire, which is connected to the main unit of the system separately and not in the wiring harness.

Dark blue wire: second channel output CH2. The negative output of the second channel 300 mA with a delay is activated when you press and hold button 2 of the transmitter key fob for more than 1.5 seconds. The operating mode of the second channel is programmable F7 functions.

The dark blue wire of the system is a low current transistor output, so it is only used to turn on an external relay.

Warning: Directly connecting the dark blue wire to the high current output of the trunk release circuit, as well as to the input of some remote vehicle start devices, will damage the main unit of the security system.

Connect the dark blue wire to pin #86 of an AS-9256 type relay (or equivalent 30A automotive relay). Connect the wires to the other relay contacts according to which function will be controlled by channel 2 of the system.

Dark green wire: input for connecting limit switches of negative polarity of the hood and trunk. The dark green system wire is the instantaneous negative trigger wire. This wire must be connected to the previously installed hood and trunk limit switches, which are permanently connected to ground.

Purple wire: Input for connecting positive polarity door limit switches, most Ford vehicles and some non-US vehicles.

Connect the system's purple wire to the positive output of one of the car's door switches, since most cars have door switches connected in parallel.

Note Do not connect the purple system wire if the vehicle has a negative door switch circuit (in this case, connect the brown system wire).

Brown wire: input for connecting door limit switches of negative polarity (General Motors cars and most non-American cars).

Connect the brown wire of the system to the negative output of one of the vehicle door limit switches.

Note Do not connect the brown system wire if the vehicle has a positive door switch circuit (in this case, connect the purple system wire).

Yellow wire: input for connecting the ignition wire + 12 V.

Connect this wire to the ignition wire that receives +12 V power when the ignition key is turned to the ignition or starter position. Make sure that there is no power supplied to this vehicle's standard wire when the ignition key is turned to the "off" position.

Orange wire: negative polarity signal output 300 mA (when the system is armed); Normally closed starter interlock relay (installation of an additional relay is required). This system wire allows you to control the operation of the starter interlock relay.

Connect the orange wire to pin #86 of the relay. Connect pin #85 of the relay to the vehicle's ignition wire, which supplies +12V when the ignition key is turned to the ignition and starter positions, and 0V when the key is turned to the OFF position. (The yellow wire of the system is also connected to the same standard wire of the car). Cut the low current wire from the vehicle's starter solenoid and connect one end of the cut wire to pin #87 of the installed relay. Connect the other end of the cut wire to pin #30 of the relay.

Note This connection is used when a normally closed starter interlock relay is installed. When using this connection, cutting off the power supply to the security system causes the starter interlock function to stop working, and this, in turn, allows the vehicle engine to start.

Black wire with white stripe: channel output SNZ

  1. Negative polarity signal 300 mA (when the system is disarmed); Normally open blocking relay (requires installation of an additional relay).
  2. Negative polarity signal 300 mA (when the system activates the channel in accordance with the programmed function (installation of an additional relay is required).

COMPLETING THE SYSTEM INSTALLATION

Antenna wire

Be sure to run the entire length of the thin black antenna wire somewhere where it cannot be damaged and secure it with cable ties. Do not wrap this wire around harnesses that include high current wires or wires for large switched loads.

Setting up the shock sensor

The warning zone of this sensor is automatically set to 30% lower sensitivity than the trigger zone. Using a small screwdriver, carefully turn the shock sensor sensitivity adjustment screw all the way counterclockwise. (Do not use excessive force when turning the adjustment screw to avoid breaking it; the maximum rotation angle of this adjuster is 270°.) Close the hood and trunk of the vehicle and arm the system. Wait 6 seconds for the accessory trigger area to stabilize, then firmly hit the rear bumper of the vehicle with your fist. The impact force must be no less than that required to break the car glass.

Attention When checking the sensitivity of the shock sensor, never hit the car window. You can break it.

Turn the adjustment screw clockwise (increasing the sensitivity of the shock sensor) approximately 1/4 turn and repeat the sensor response check. Repeat this procedure until the system operates and the alarm sounds. Eventually, one significant hit to the car's bumper will cause the siren to sound a series of warning signals.

Warning! Selecting a shock sensor sensitivity that is too high will result in false alarms of the system from strong vibrations, which are created, for example, by passing trucks or heavy equipment. To reduce the sensitivity of the shock sensor, turn the sensor adjustment screw counterclockwise.

System wire protection

Always route security wires in corrugated conduit or protect them by wrapping them in a spiral pattern with electrical tape. Secure the entire length of the wire harnesses using cable ties. Securing it securely will prevent the harness from coming into contact with hot engine surfaces or sharp moving vehicle parts, which could damage the insulation of the system wires.

Exploitation

The installer must mark all installed options and programmed settings in the user manual and fully explain to the car owner the rules for operating the security system.

WIRING DIAGRAM APS-2500


Currently, among the feedback alarms belonging to the middle class, which fully ensure the solution of the tasks set to preserve safety, the “Sheriff” system has proven itself well, which, among other things, attracts motorists with a number of additional functions (for example , the presence of RFID locking and the ability to autostart), as well as an affordable price and ease of installation during installation.

Most car alarm systems offered on the modern market are accompanied by fairly detailed instructions, meanwhile, in each specific case, when dealing with the problem of how to connect a sheriff alarm, you have to take into account many quite important nuances.

The installation of any car alarm, as a rule, begins with choosing a location for the main control unit. Practice shows that it is most convenient for these purposes to use the compartment behind the glove compartment or the free space under the ventilation and heating control unit.

It is best to avoid attempting to install this unit in the engine compartment. Not only is there an increased risk of moisture and other aggressive liquids getting in there - there are many components in the engine compartment that can interfere with the radio signal, and this, in turn, leads to a decrease in the range of the system and creates conditions for false alarms.

The block is secured in the selected location with the supplied screws or using special braces. As for the engine compartment, it is much more appropriate to install a siren in it, and such a place should not be too accessible from the outside, remote from moving elements and protected from moisture.

When installing the hood limit switch, you should not forget that it must be fixed on a metal surface that is securely connected to the general “ground” of the car, while when pressing and closing the hood, the limit switch rod must move at least 6 mm, and when opening, it must rise completely.

It is best to mount the shock sensor on the hard surface of the jumper between the engine compartment and the passenger compartment (on the passenger compartment side).

The LED is placed so that it best suits its main purpose, that is, it warns a potential attacker as early as possible about the presence and enabled state of the security system.

The Valet button requires a particularly reverent attitude, which, after installation, must be both hidden from view and, at the same time, as accessible as possible to the driver

To connect individual components of the alarm system, you will have to do a certain amount of work in the cabin: make wire leads from the ignition switch (on which +12V voltage appears when the ignition is turned on), stretch the wires going into the cabin from the siren and the hood limit switch (and possibly the trunk ), make a reliable diversion from the nearest “mass”.

When installing such a system, you may have to cut the standard register for controlling the electric drives for controlling the door locks. As a rule, these wires are laid from the main locking (unlocking) switch to additional switches and then to the electric lock drives. For the normal functioning of the security system, the wire going to the main switch is connected to the green wire of the system, and the wire going to the electric drives is connected to the yellow one.

The car alarm connection diagram included in the kit provides complete information about the color masking of the wires and their connection locations. The only thing you should pay attention to is protecting the wires using special corrugated tubes and insulating tape, as well as securely fixing them with cable ties.

Almost every car today is equipped with an anti-theft system. - this is not a tribute to fashion, but the need to protect your vehicle from burglary and theft. Consumers are offered a large selection of different alarms, and each model has its own characteristics, advantages and disadvantages. What functions does the Sheriff alarm system have, how to connect it correctly and what malfunctions can occur in its operation - find out in this article.

Peculiarities

How to connect an alarm with feedback and auto start to a car, how to set up the start, how to turn off the device and what is the best way to install it? First, let's look at the features of the system. produced by Progressive Innovative Technology from the USA. As a result of numerous tests, the alarms of this brand have shown their effectiveness and functionality. Initially, the Sheriff car alarm was conceived as a budget anti-theft system.

Key Features:

  • availability of two-way communication on almost all modern models;
  • car alarm allows you to control the central locking remotely, locking the car doors;
  • work with the satellite module;
  • the car owner can set and disable the security system, while relying on the readings of the key fob;
  • active and passive modes for installing a car on protection;
  • if the Sheriff car alarm has an automatic start function, then the driver will be able to start and block the engine from a distance;
  • The kit includes a shock controller with an alert function;
  • the ability to recognize the owner of the vehicle at a distance when approaching the car;
  • reliable protection against signal interception and scanning, which greatly increases the safety of the machine;
  • the ability to set a security mode on the car even if the engine is running;
  • the possibility of motion recognition, as well as wiretapping of the vehicle interior with further notification to the car owner (the author of the video is the Avtozvuk.ua channel - Avtozvuk Database).

These functions are typical for almost all signaling models.

Types and models

Briefly about the most popular alarm models:

  1. ZA-1095. It is characterized by the presence of four service channels, as well as additional protection against theft. There is an option to autostart the power unit.
  2. APS-2500. Equipped with a two-level shock controller, it is possible to activate security when the engine is running. A distinctive feature is that this model has its own charger.
  3. ZX-945. It is characterized by the presence of a dynamic signal coding system, as well as the Disarm Dialog option.
  4. ZX-750. Large range of up to 2 km, of course, if we are talking about clear areas.
  5. APS-2400. This model is characterized by the presence of one-way communication, but this does not make it less reliable and functional. The presence of a dynamic encryption code, which allows you to reliably protect the system from signal interception.
  6. APS 35PRO. Complete “stuffing” - autostart, the ability to remotely control using a remote control, the presence of a two-channel receiver, a two-level shock controller, etc.
  7. ZX-1055. This system belongs to the multifunctional category. A device with 5 communication channels, as well as advanced protection against vehicle theft. If the car is hacked, the engine will be blocked (video author - Andrey Tarakanov).

You can find many other models of anti-theft systems on sale, but the most popular ones are listed above.

Instructions for use

The following should be included with the alarm:

  • Sheriff alarm connection diagram;
  • operating instructions - installation and configuration must be carried out in accordance with the manual;
  • two keychains;
  • siren;
  • control unit;
  • a set of wires and connectors for installation and connection;
  • antenna;
  • Valet button;
  • LED status indicator;
  • shock sensor

Briefly about how to install and connect the alarm:

  1. First, the control unit is installed. It is best installed behind the center console to prevent possible intruders from gaining access to it.
  2. The siren is installed next, it is installed in the engine compartment, the siren is placed with the horn down.
  3. Then connect the shock sensor - it needs to be placed somewhere in the center so that it reacts to touches on the car from all sides.
  4. The antenna module and LED indicator light must be installed on the windshield. The antenna is connected after its installation, but the installation must be done in such a way that there are no metal components near this device.
  5. Then you need to install the Valet service button - it also needs to be installed in a place inaccessible to criminals.
  6. Now you need to organize a circuit between all the connected elements - to do this, lay the wires and connect all the system components with them.

The setup procedure is carried out in accordance with the service book.

If you don’t know how, and the system does not respond to key fob commands, then you have two options:

  1. Perform manipulations with the signaling wiring, that is, disconnect the power from the control module. This method is radical and can be used as a last resort.
  2. Disabling can be done using the Valet button. The shutdown procedure should also be described in more detail in the service book, since it is individual for each model. In Sheriff signaling, as a rule, to turn it off, you need to activate the ignition, then press the button, turn off the ignition and activate it again, and then press Valet again.

Important!

The system has six independent (two of them are remotely controlled) functionally reprogrammable channels. These are six physical wire lines with programmable operating logic, providing flexible changes in system functions for controlling the shutdown of turbocharged engines (turbo timer), searching for a car in a parking lot, remotely turning off the system siren in “NIGHT” mode with a control channel for an additional pager or mobile communication device, security service a car with the engine running without an ignition key, control of additional devices at specified time intervals.

The interactive pager provides real reception of signals confirming the execution of a command by the system. During one security cycle, the system provides information about each triggered sensor on the LCD display of the two-way communication key fob.

To ensure the highest level of protection for your vehicle, this security system has a programmable manual override feature. In some cases, for example, when the key fob transmitter for remote control of the system is lost or does not work (or perhaps your key fob transmitter is blocked by powerful radio emissions from a jammer type device), you may need to manually arm or manually disarm the system. Read the sections “Manually arming the system” and “Manually disabling the security system,” which detail the procedures for arming and disarming the system in such a situation. In addition, this manual contains a table in one section of which the system functions are used, including the selected system shutdown method, and the optional equipment installed in the vehicle. Although the "Secret Code" function is not programmed by default (you must enter a personal code to disable the system), the Valet switch can also be selected to disable the system. See which method was programmed to shut down your system and review it in the appropriate section of this manual.

If the F13 "Secret Code" function is programmed, then writing codes for new key fobs, changing the secret code, changing the status of programmed functions from F12 to F27, emergency disarming of the system, turning off the system when triggered in Anti-Hi-Jack modes are possible only after entering the secret code! Changing the parameters of functions F1 to F11 does not require entering a secret code and is always available.

Transmitters with technology to protect digital codes from interception (Keeloq)

The key fob transmitters included with this security system use the most advanced and reliable form of radio frequency transmission of any car security system currently available. Some of today's sophisticated car thieves use devices known as code grabbers, which allow them to receive and store the signal sent by the car's remote control device. After the driver leaves, this code is used by the thief to disarm the system.

Unlike the remote control devices described above, the key fob transmitters included with your security system change the code of the transmitted signal every time the button is pressed, so when a thief plays the intercepted signal from your key fob transmitter, the security system simply will not respond to it. If the button on your transmitter key fob is pressed more than 30 times when it is outside the control of the security system (for example, children are playing with it), the system will not respond to the call from the transmitter key fob when you decide to use it again. You need to synchronize your key fob transmitter with the security system receiver. To do this, simply press the system arming/disarming button on the transmitter key fob twice within one second. After this, the system will again respond to all remote control commands.

ANTI-BIGGER ACTIVE TRANSPONDER

ANTI-BURRY ACTIVE TRANSPONDER is designed to increase the effectiveness of the protective properties of the security system, ensure the return of the car and the safety of the owner. The built-in function F14 allows you to select one of three operating modes.

F14/1 - state "off". The system eliminates the use of an active transponder.

F14/2 - first stage hidden security mode. The system detects the presence of a transponder every time the ignition is turned on, confirming with a single beep. Subsequent security actions are carried out silently in cyclic mode. Transponder in the working area - normal system operation. The transponder is outside the working area - the system includes blocking circuits. Placing (turning on) a transponder in the work area ensures the restoration of break circuits. This device operation algorithm has no time or quantitative restrictions.

F14/3 - second stage hidden security mode. The system detects the presence of a transponder, confirming with a single beep each time the ignition is turned on. Subsequent security actions are performed in the mode of switching on the blocking algorithm of the ANTI-HI-JACK type with other time parameters if the system has “lost” the transponder. Transponder in the working area - normal system operation. The transponder is outside the working area - the system starts the ANTI-HI-JACK mode. Subsequent placement (switching on) of the transponder in the work area does not ensure restoration of the break circuits. The system can be "restored" using the Valet button or by entering the Secret Code.

Manually arming the system

If for any reason you cannot use the key fob transmitter to arm the system, you can do this using the Valet button at any time, even if you do not have the ignition key.

Full system arming
  1. Briefly press, release, and then press and hold (more than 3 seconds) the VALET button until the activation of the arming mode is confirmed by an audible signal.
  2. The LED will flash quickly to indicate that the last door is waiting for the door to close:
    1. if the door was closed, the system will wait for the last door to open and then close,
    2. if a door was opened, the system will wait for the last door to close.
  3. After the last door is closed, and after 3 seconds, the full security mode will turn on.
Manual arming is performed only for one cycle before the system is disarmed.

Note After turning off the ignition, manual arming can only be performed after a 5-second delay.

Additional (emergency) call via pager signal

  • The system has an additional channel for transmitting a call/notification signal to the owner of the two-way COMMUNICATION key fob. Call control can be carried out by a second person in the car and activating the "CALL" button on the pager module. A call signal is generated when you press and hold the "CALL" button for more than 2 seconds.
  • The beepper of the two-way COMMUNICATION key fob begins to emit a frequently repeating sound signal for 5 seconds. The vibration alert is also activated for 5 seconds.
Protecting the car when the security mode is on
  • Opening the hood, trunk or door of the car will immediately trigger the system and turn on the alarm. The siren will sound and the vehicle's side lights will flash for 30 seconds. After this, the sound of the siren and the flashing of the side lights will stop and the system will continue to monitor all vehicle protection circuits. If a burglar or carjacker left the door open, the siren will sound for six 30-second cycles and then turn off; this protection zone will be isolated and the system will continue to monitor the remaining protection circuits of the vehicle.
  • Each time the system is armed, the red LED indicator installed in the vehicle's dashboard begins to flash slowly. The flashing LED indicator serves as a visual warning to potential burglars or car thieves. The indicator uses a light-emitting diode that consumes a small current, so even if the system is left in the security mode for a long time, the operation of the LED indicator will not drain the vehicle's battery.
  • Each time the system is activated, the vehicle's side lights flash for the entire 30-second alarm cycle, drawing attention to the vehicle.
  • Additional feature: every time the system is armed, the vehicle's starter circuit is blocked. In this case, the car engine cannot be started even with the ignition key.
  • When the system is armed, any strong blow to the car body or glass will trigger the shock sensor and turn on the alarm.
  • Weaker impacts will trigger the shock sensor's warning zone, causing the siren to emit a series of short warning tones.

Car protection when the security mode is on and the engine is running

  • Opening the hood, trunk or door of the car will immediately trigger the system and turn on the alarm. All blocking circuits will turn on. The siren will sound and the vehicle's side lights will flash for 30 seconds. After this, the sound of the siren and the flashing of the parking lights will stop, and the system will continue to monitor all vehicle security circuits. If a burglar or carjacker left the door open, the siren will sound for six 30-second cycles and then turn off; this protection zone will be isolated, and the system will continue to monitor the remaining protection circuits of the vehicle.
  • The LED indicator will begin to flash slowly. Each time the system is activated, the vehicle's side lights flash for the entire 30-second alarm cycle, drawing attention to the vehicle.

Passive (automatic) arming of the system

  1. Turn off the engine, get out of the car, close all doors, hood and trunk.
  2. The LED will begin to flash rapidly, indicating that the system's 30-second passive arming timer has started.
  3. After 30 seconds, the system will turn on the security mode.
  4. The vehicle's parking lights will flash once.
  5. The siren will emit one short confirmation beep.

If there is an additional door locking/unlocking circuit and programmable function F27 (door locking during automatic arming) is enabled, then the vehicle doors will be locked.

Note If the vehicle's door, hood or trunk is opened while the passive arming timer is running, the system's passive arming timer will be paused. When all doors, hood, and trunk are closed, the system will begin the passive arming cycle from the beginning. At the end of the 30-second time interval, the security mode will turn on.

Warning signals about an attempt to break into a car

If an attempt was made to break into the car in your absence, the security system will inform you about this.

When the system is disarmed, four short beeps will sound and the side lights or direction indicators will flash four times.

Sit in the car and before turning the ignition key, watch the LED indicator on the car's dashboard blink.

  • If the LED indicator blinks once after a pause, then the system was triggered by the first shock sensor or by the trigger of an additional device connected to the system.
  • If the LED indicator blinks twice after a pause, then the system was triggered by a second shock sensor or by a trigger from an additional device connected to the system.
  • If the LED indicator blinks three times after a pause, then the system was triggered by the trunk or hood limit switch (when trying to open the hood or trunk) INSTI(-), INST2(-) = INST1(-) (when INST2J-) is an additional input trigger) .
  • If the LED indicator flashes four times after a pause, then the system was triggered by the door limit switch (when trying to open the car doors) DOOR(-), DOOR(+).

Warning signals about an attempt to break into the vehicle are stored in the system memory and are erased when the ignition is turned on.

Valet Push Button Switch (VALET Mode)

The Valet push-button switch allows you to temporarily disable all security functions of this system, eliminating the need to take your system's control transmitter to a parking attendant or service station mechanic.

Automatic door locking when the ignition is turned on (function F3/2)

If your vehicle is equipped with optional power door locks, this system can be programmed to automatically lock the doors when the ignition is turned on. Every time you turn on the ignition, after 3 seconds the car doors will be locked to ensure your safety. If any of the doors is open at this moment, the doors will not be locked. If you would like to enable this feature, please contact your installer or see the Programmable Features section.

Automatic door locking when the vehicle starts moving (function F3/3)

If your car is equipped with an electronic speed sensor and additional electric door locks, this system can be programmed to automatically lock the doors when the car starts moving - after 3 seconds the car doors will be locked to ensure your safety. If any of the doors is open at this moment, the doors will not be locked. If you would like to enable this feature, please contact your installer or see the Programmable Features section.

Automatic door unlocking when the ignition is turned off (function F4)

If your car has additional electric door locks, then each time you turn off the ignition, the car doors will automatically unlock. If you wish to disable this feature, contact your installer or see the Programmable Features section.

AV FUNCTION - disarming the system in two stages

Disarming the system in two stages allows you to further increase the anti-theft protection of your car against “electronic tampering” with devices like 409, etc. If the AV trigger function (F21) is enabled, arming the system with a key fob transmitter or using the Valet button will set all ARM, ARM blocking circuits to the armed state. When performing the "DISARM" operation using a transmitter key fob, the system will unlock the doors, turn off the input triggers of the doors, hood, and trunk, but will not turn off the interlock circuits. To finally unlock the system, use the Valet button or enter your Secret System Unlock Code, in which case the interlock circuits will be closed and the engine can be started.

If the TURBO TIMER function is activated, the system will delay the activation of the ARM, ARM blocking circuits for the duration of the turbo timer, ensuring engine operation without the ignition key. The engine will then be automatically turned off, all interlock circuits will be turned on and the sensor channels will be activated.

PASSIVE ENGINE LOCK (immobilizer function) with AV function

Passive engine blocking (immobilizer function) ensures automatic activation of the ARM, ARM blocking circuits 20 seconds after the ignition is turned off.

  1. Stop the engine and turn off the ignition. After 20 seconds, the LED indicator begins to flash slowly, indicating the active state of the immobilizer function.

    To disable passive engine immobilization

  2. Turn on the ignition. The system begins to confirm the active state of the immobilizer function with short-term sound signals (the engine cannot be started).
  3. Briefly press the disarm button of the key fob transmitter to turn off the blocking circuits, or press the Valet button or enter the Secret Code if the passive blocking function F17/2 is enabled.
  4. Briefly press the Valet button or enter the Secret Code to disable the ARM and ARM interlock circuits if the F17/3 passive interlock function (PDU with AV function) is enabled. In mode F17/3, it is impossible to disable passive locking from the key fob transmitter.
  • If the TURBO TIMER function is activated, the system will delay the activation of the ARM, ARM blocking circuits for the duration of the turbo timer, ensuring engine operation without the ignition key. Then the engine will be turned off automatically. Then, after 20 seconds, all blocking circuits will turn on in the PASSIVE ENGINE BLOCKING mode.
  • The passive engine blocking function is independent of the state of function F21 (AV trigger).

Remote control of additional devices (channel CH2)

This system has a CH2 channel (dark blue wire) for controlling various additional devices connected to the system. This channel can be used (programmed) for:

  • remote control of car window lifter,
  • control the security mode of a car with the engine running without an ignition key,
  • control of trigger type devices. Programmable functions TRIGGER1 (output control at any time and in any system state), TRIGGER2 (output switching on at any time when the ignition is on and in any system state, static output switching off at any time and in any system state).

To supply a control signal to an additional device via channel CH2, use key fobs-transmitters according to Table 1, Table 2 of system control commands, and also use the table of programmable functions to select the required parameters.

The CH2 output is connected to ground during the channel activation time.

Channel output CH2 is a low-current output designed to control the coil of an additional relay or an equivalent low-current load.

  • remote control of timer devices,
  • control devices at specified time intervals,

The CH3 output is connected to ground during the channel activation time. The channel is activated immediately when you press the CH3 button.

To supply a control signal to an additional device via channel CH3, use key fobs-transmitters according to Table 1, Table 2 of system control commands, and also use the table of programmable functions to select the required parameters.

The output of channel CH3 is two outputs of a normally open relay with a load current of no more than 1 A.

Note If the CH3 output was activated while the system was in armed mode, the system will simultaneously disable the shock sensor and the hood/trunk trigger so that opening the trunk does not trigger the system. After the trunk is closed, the system will automatically protect this circuit again.

Remote control of additional devices (channel CH4)

This system has a CH4 channel (green wire with a white stripe) for controlling various additional devices connected to the system. This channel can be used (programmed) for:

  • remote control of timer devices,
  • pulse output of negative polarity for 1/10/20/30 sec when arming the system: (use option - as an output for controlling power windows, electric sunroof, etc.),
  • Pulse output of negative polarity for 20 seconds when the system is disarmed (use option - polite backlight control output). Turning the ignition on will cancel the pulse at any time.

The CH4 output is connected to ground during the channel activation time.

Channel output CH4 is a low-current output designed to control the coil of an additional relay or an equivalent low-current load.

Remote control of additional devices (ARM channel)

This channel can be used (programmed) for:

  • additional ARM blocking output,
  • control the shutdown of turbocharged engines or other automatic equipment.

The ARM channel output is connected to ground during the channel activation time.

The ARM channel output is a low-current output designed to control an additional relay coil or an equivalent low-current load.

  • additional blocking output,
  • control of an additional pager device.

The CH5 output is connected to ground during the channel activation time.

Channel output CH5 is a low-current output designed to control the coil of an additional relay or an equivalent low-current load.

Remote control of additional devices (channel CH6)

This system has channel CH6 (wires blue with a red stripe and blue with a black stripe) for controlling various additional devices connected to the system. This channel is programmed as:

  • pulse output of negative polarity for 20 seconds when the system is disarmed (use option - polite backlight control output). Turning the ignition on will cancel the pulse at any time,
  • control of shutdown of turbocharged engines or other automatic equipment,
  • W-TRIGGER - launch and reset of a channel via radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes),
  • W-impulse 1 sec - launching a channel via a radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes),
  • W-impulses 1 /0.5/1 sec - launching a channel via a radio signal from a two-way communication key fob in real time (according to a daily timer - hours, minutes).

Note To enable or disable control of the CH6 channel in the “W-functions” mode, press and release the combination of buttons F(5)+ 4.

  • Control is allowed - "SET" - indicator on the LCD.
  • Control is prohibited - there is no "SET" indicator on the LCD.

The CH6 output is connected to ground during the channel activation time.

The output of channel CH6 is two outputs of a normally open relay with a load current of no more than 1 A.

Note If the CH6 channel output was activated while the system was in security mode, the system will simultaneously turn off the shock sensor for a while so that opening the trunk does not trigger the system. After the trunk is closed, the system will automatically protect this circuit again.

Turbo timer function

The turbo timer function can be activated on the ARM and CH6 physical lines by programming functions F22/2 and F24/3. The lines are activated by turning the ignition key to the “IGNITION ON” position and remain in this state indefinitely as long as the ignition is on. TURNING OFF THE IGNITION leads to the activation of the line deactivation delay timer, programmed by the F1 function (for 1/2/3/10/30 minutes). Thus, after the time specified in F1 has expired, the turbo timer lines will go into an inactive state.

It is possible to urgently disable the turbo timer only using the key fob transmitter at any time.

Resetting the ACTIVE STATE of the turbo timer
  1. Remove the key from the vehicle's ignition.
  2. Within 1 second, press button 3 twice (Fig. 1).
  3. The system must confirm receipt of the command with two short beeps and one short light signal, then reset the turbo timer channel.

Programming codes for new transmitters and transponders

Please note that when programming a new transmitter into the system's memory, all previously programmed transmitter codes are erased, so when programming additional transmitters, existing transmitters must be re-programmed.

Attention!

Since the transmitters use a constantly changing (dynamic) code, in some situations (for example, when pressing the key fob buttons more than 30 times outside the system's coverage area), desynchronization of the key fobs and the system may occur. In this case, go to the car and within one second press button 1 (Fig. 1, Fig. 2) of the transmitter twice. Synchronization will be restored, and the key fob will again be able to control the system.

Transmitter programming

Recording codes for new transmitters (F13 - "Valet" state).

Attention!

Remember that each operation must be performed within 5 seconds after the previous operation. If the 5 second interval is exceeded, the system will automatically exit programming mode, which will be confirmed by one short and one long beep from the siren. If the ignition was turned off during programming, the system will immediately exit the programming mode, confirming this with one short and one long siren signal.

  1. Disarm the system, get into the car and turn on the ignition.
  2. Press the Valet pushbutton switch 3 times. You will hear one siren sound to confirm that the system is ready to program new transmitters. Press and hold button 1 (Fig. 1) of the first transmitter until you hear a long siren signal confirming that the programming of the first transmitter is completed (the transmitter channels will be programmed automatically). The LED will begin to flash slowly.
  3. Press and hold button 1 (Figure 1) of the second transmitter until you hear a long siren signal confirming that programming of the second transmitter is complete. The LED will begin to flash slowly.
  4. Repeat step 3 for the remaining transmitters.
  5. To exit transmitter programming mode:
    1. turn off the ignition or
    2. wait 8 seconds without performing any actions.

You will hear one short and one long beep to confirm that you have exited transmitter programming mode, and the system LED will turn off.

Recording codes for new transmitters (F13 - Secret code status)
  1. Disarm the system using a key fob or by entering the Secret Code with the "Valet" button, i.e.
    1. turn on, turn off and then turn on the ignition,
    2. using the Valet switch, enter the first digit of the code (the number of presses of the Valet button corresponds to one digit of the code),
    3. using the Valet switch, enter the second digit of the code (the number of times the Valet button is pressed corresponds to the second digit of the code),
  2. Press the Valet pushbutton switch 3 times. You will hear one long siren signal.
  3. Press button 1 (Fig. 1, Fig. 2) of the first key fob transmitter. The system will confirm the recording of the new key fob code into memory with a sound signal.
  4. Press button 1 (Fig. 1, Fig. 2) of the second transmitter key fob. The system will confirm the recording of the new key fob code into memory with a sound signal.
  5. To record the code of an active anti-robbery transponder, turn on (or turn off and then on) its power. The system will confirm the code recording with a sound signal.

Attention!

Remember that each operation of writing the codes of new key fobs deletes the codes of old key fobs from memory and must be performed for all key fobs at once. The system maintains up to four key fob codes in memory, regardless of whether the codes are from four different key fobs or the same code is written into the system four times.

System Function Programming

Reprogramming the states of functions F1 to F11 is always available regardless of the state of function F13 without entering a secret code.

If F13 is set to Valet mode, reprogramming is carried out in the usual way from F1 to F27 inclusive.

If F13 is set to Secret Code mode, reprogramming the states of functions F12 - F23 is only possible after entering the secret code.

  1. Enter the secret code.
  2. Program the functions in the sequence F1, F2 - F27.

If the secret code is not entered, it is possible to reprogram only functions F1 to F11; when you try to go to function F12, the system automatically exits the programming mode.

The system automatically exits the reprogramming mode after 15 seconds of waiting or immediately after turning off the ignition.

1. Entering programming mode (F13 - Valet state)
  1. Disarm the system using the key fob or Valet button.
  2. Turn on the ignition.
  3. Within 3 seconds after turning on the ignition, press the Valet button switch 3 times. You will hear one long siren signal.

After the siren sounds, you can either

Note

2. Entering programming mode (F13 - Secret code state):
  1. Disarm the system using a key fob or Valet button by entering a secret code
    1. turn on, turn off then turn on the ignition,
    2. using the Valet switch, enter the first digit of the code,
    3. turn off and then turn on the ignition,
    4. using the Valet switch, enter the second digit of the code,
    5. turn off and then turn on the ignition. The system should confirm with an audible signal that the correct code has been entered.
  2. Press the Valet pushbutton switch 3 times. You will hear one long siren signal.
  3. Turn off the ignition within 3 seconds after the siren signal. You will hear one short and one long siren signal.
  4. Turn on the ignition within 3 seconds after the siren sounds. You will automatically enter the F1 function programming mode. The LED will begin to flash single flashes.

In the programming mode of a particular function, the number of LED flashes corresponds to the number of the programmable function, and one, two, etc. siren signals indicate the status of this function.

After the siren signals you can

  • change the state of this function (by pressing button 1 (Fig. 1) of the transmitter). In this case, you will again hear 1 or 2 or 3 or 4 or 5 siren signals according to the new state of the function,
  • move to the next function (by pressing the Valet button once),
  • exit programming mode (for example, by turning off the ignition).

Note

Do not allow more than 10 seconds to pass between your actions, otherwise the system will automatically exit the programming mode and you will hear one short and one long siren signal.

Operating modes of the LED indicator of the LED system installed in the car dashboard

Short confirmation signals given by the system siren

Operating modes of vehicle side lights

Note

If the alarm went off in your absence, then when you disarm the system, I will call you! chat four short beeps and the parking lights or direction indicators will flash four times, and the LED indicator will flash according to the code that corresponds to the zone that was activated in your absence.

Before starting your car, watch the LED indicator on your car's dashboard blink. The number of flashes of the LED indicator indicates the zone protected by the system that triggered the system in your absence. For more information, see the "Vehicle Intrusion Warning Signals" section of this manual.

An attempt to disarm the system after the system has been triggered (the alarm siren has turned on) will only result in the audible alarm being turned off. The system will not be disarmed. In order to disarm the system, you must press the arm/disarm button on the key fob transmitter when the system does not sound an alarm.

Replacing batteries

A small red LED is installed in the transmitter housing, which confirms that the transmitter buttons have been pressed and also indicates the battery status. As the battery drains, you may notice a decrease in the transmitter's range. To replace the battery

  1. open the cover by unscrewing the small screw on the back of the transmitter housing,
  2. remove the dead battery, remember its polarity and dispose of it properly,
  3. install a new battery (type GP23A), make sure the polarity is correct,
  4. Carefully install the cover without damaging the LED or switches on the circuit board, and tighten the small screw on the back of the transmitter housing.

INSTALLING THE SYSTEM

Installing the main system components

Connecting system wires

ATTENTION!

When connecting additional relays to the security system outputs, make sure that there is a damping diode on the relay control contacts. Connect the security system output to the additional relay only from the anode side of the snubber diode. Make all connections to the security system wires only with the security system power circuit fuses removed. If there is no damping diode in the additional relay, the polarity of its connection is arbitrary.

Warning

Direct connection of low-current channel outputs to the high-current executive input of the car trunk lock opening circuit, as well as to the input of some remote vehicle engine start devices, will damage the main unit of the security system.

Trunk release control

Connect the selected control channel wire to the control contact of an AS-9256 type relay (or equivalent 30A automotive relay). Connect the wires to the other relay contacts according to your control circuit. A diagram of the approximate use of channel 2 to control the trunk opening is shown below:


Standard car door locking/unlocking configurations

Three-wire negative door unlock/lock circuit

The orange wire and the blue wire with a white stripe should be connected to ground (a metal part of the car body).

The yellow wire is the negative locking pulse output and must be connected to the control wire of the stock negative locking relay. The white wire is the negative release pulse output and must be connected to the control wire of the standard negative release relay. The control circuit for the central locking channel with negative trigger is shown below:


Three-wire door unlock/lock circuit, positive polarity

When installing the system in such vehicles, the dark green and dark blue wires for locking/unlocking the car doors are not used.

The orange wire and the blue wire with a white stripe should be connected to the +12V power supply.

The yellow wire is the positive locking pulse output and must be connected to the control wire of the standard positive locking relay. The white wire is the positive release pulse output and must be connected to the control wire of the standard positive release relay. The control circuit for the central locking channel with a positive trigger is shown below.


Five-wire door unlock/lock circuit with polarity reversal

When installing the system on such cars, it is necessary to cut the standard control wires for the electric drives of the car door locks. These wires are routed from the main lock/unlock switch to the auxiliary lock/unlock switches, and from them to the power door lock actuators.

Cut the stock locking wire and connect the yellow system wire to the end of the cut stock wire that goes to the auxiliary switches (power door locks). Connect the green wire to the end of the cut stock wire that goes to the main switch.

Cut the standard unlocking wire and connect the white system wire to the end of the cut standard wire that goes to the additional switches (power door locks). Connect the blue wire to the end of the cut stock wire that goes to the main switch.

The orange wire and the blue wire with a white stripe must be connected to a fused +12V power source.

Exploitation. The installer must mark all installed options and programmed settings in the user manual and fully explain to the car owner the rules for operating the security system.
