APS 2550 alarm connection diagram. APS alarm - a detailed overview and operating instructions. Anti-false alarm function
What does a motorist expect from a security system? Undoubtedly, a high degree protection, a sufficient set of service functions, the ability to self-assembly(settings) and stable operation. APS alarm fits all criteria. It can rightly be called one of the most successful products on the anti-theft system market.
The owner of the car, who decides to get acquainted with the capabilities of this product in more detail, may be confused by the search engine results on the request Aps. Most likely, the user will be presented with a list of articles on the characteristics of automatic fire system(APS), but if you use the correct abbreviation (APS), then necessary information about car alarms of this brand will become available and the motorist will have the opportunity to learn about all the benefits that their installation and operation promises.
High efficiency of security functions
Manufacturers of APS car alarms have relied on the Keeloq dynamic radio channel interception protection code and were not mistaken.
Information about what this technology is outdated, and such a security barrier can be easily bypassed using a code grabber (a device designed to decode, remember and repeat an "overheard" code) - this is just a myth. Only the most unsuccessful of its implementations, used by manufacturers according to the scheme of using one key for all systems of their brand, can be hacked (such an unsuccessful technology has nothing to do with Aps).
A different principle applies here: the format of the packet transmitted over the radio channel from the key fob to the system changes with each next press of the button (the alarm codes already used earlier are simply discarded), which means that it is impossible to write them down and repeat them for subsequent disarming.
This technology is used for all APS alarms, regardless of price category and model (be it aps1500, aps 3900, aps 5100 or aps 9000).
Budget models: functionality
Another secret of the popularity of this brand of alarms lies in the optimal set of options that Aps security systems can boast of. The motorist has the right to choose which of the functions he wants to get for his money. The choice of models is huge, the optional features are different. Someone would prefer a sufficient minimum:
- one-way communication(when trying to steal, only a sound siren will work, other signals - an alert on the key fob, phone, will not be received);
- central lock control(automatic unlocking / locking of doors using the control panel);
- service mode (valet button, necessary for binding, reprogramming the key fob and emergency disarming);
- "panic" mode (the ability to turn on sound and light alarms from the remote control if necessary, for example, to attract attention or search for a car in a parking lot);
- silent arming/disarming(the alarm will be turned on or off without a single sound);
- status LED(LED is a kind of beacon that allows you to understand whether the security mode is on or off).
If these opportunities are enough and overpaying for more functionality is not included in the plans of the motorist, then you should pay attention to the following models:
APS 2500, 3700, 2550, 3900, aps 2900 (the instruction manual will give a clear idea of the list of specific functions that the owner of the machine will be able to use after installing these aps alarms).
Business class models: extended optional set
APS alarms, which are one step higher, can please their owner with a wider range of service functions. In their arsenal there are also such useful options as:
- Feedback . The system informs about an attempted hijacking not only by a sound siren, but also by a message on the key fob, phone.
- Anti-Carjacking mode (anti-robbery). Blocks the engine during a robbery attack 30 seconds after pressing the button (with the ignition off).
- Anti-Hi-Jack mode. Blocks the engine while driving. Provides two options:
- passive (relevant when the owner of the car is driving, and the attacker is trying to take possession of the vehicle from the passenger seat);
- active (used if the machine is already controlled by an intruder, but it is still in the range of the key fob).
- Automatic engine start. The motor starts to work under certain conditions: at a specific time, at a specific air temperature, after a specific time interval (autostart without an alarm will cost more).
- Comfort-enhancing features. One of the most useful options is remote control, including:
- power windows;
- door, hood, trunk locks;
- "polite interior lighting";
- direction indicators.
It's only short review useful alarm options of this line (aps 2100, 2800, 5300, 2700). Each model is a set of the above features + bonus options. So, for example, aps 7100 two way can also please with the mode passive blocking engine, and aps 2300 automatic re-arming.
Captivating factors: affordable installation and connection
What else makes APS alarms attractive to a car enthusiast? The opportunity to save not only on their cost, but also on installation and connection. It is quite possible to hold this event on your own (no need to spend money on paying professionals).
All you need is information about the competent localization of system elements and a detailed connection diagram. To help the new owner of the aps alarm, the instruction manual, which is mandatory included in its package.
To the acquaintance of motorists who have decided to independently install the APS alarm useful information from the relevant sections of this manual, concerning the following points:
- Location of system elements. The basic principle of the location of the alarm components: away from heating parts and places not protected from moisture (central unit under/behind the instrument panel, antenna on the windshield, siren under the hood with the horn down, more details in the installation manual).
- Connection. The first rule (it is also golden and reliable) is to act according to the scheme given in the instructions, not bypassing the manufacturer's recommendations, which are highlighted there, and everything will work stably and for a long time. Special knowledge is not required, there are simply no incomprehensible moments left (everything is clearly described in the instructions: red wire to green wire, yellow to black wire), it is accessible and understandable, it is unrealistic to make a mistake.
That's all. The APS alarm is installed, it remains only to configure the necessary parameters.
It's as easy as shelling pears: programming the protection system
The initial task is to bind the key fob (until the control panel is connected to other alarm elements, neither 100% protection nor convenient operation is out of the question). Acting step by step, you can activate the key fob on your own in a couple of minutes.
A detailed algorithm of actions required to bind a key fob (for example, aps 1350, relevant for all models) looks like this:
- Step 1 . Turn the ignition on and off 5 times (system behavior: sound signal - 5 short sirens, light signal - 5 short flashes).
- Step 2. We move the service switch "Valet" to the "ON" position, change it to the "OF" position, repeat the action 5 times (system behavior: no change).
- Step 3 We press the large left button of the key fob (system behavior: no later than 10 seconds after the system is notified about the transition to the programming mode by 5 sound and light signals, the subsequent 1 short beep means that the key fob has been entered into the security memory).
- Step 4 We repeat the action number 3 for each subsequent key fob (system behavior: each memorization of a new element is accompanied by a corresponding number of short beeps, for example, three - the third key fob is stored, two - the second remote control is stored in memory, one - the first key fob is “registered”).
- Step 5 We are waiting for the exit from the programming mode, 10 seconds after registering all the key fobs, the alarm will automatically turn off (system behavior: 5 short alarm signals).
The secondary task is to program (configure) the available functions. Everything is simple here: you need to act clearly according to the instructions and everything will work out!
APS: not yet perfect, but aiming for perfection
Failures in the operation of any alarm system is an inevitability that every owner may face vehicle. Unfortunately, the questions: how to turn off the Starline, Pharaoh, Panther, APS alarms without a key fob are still relevant. It is possible that in the future the search bar of browsers will not be loaded with similar requests from car owners who have installed security system data on their car, but today they have a place to be.
The main problem with this brand protective systems lies in the fact that the aps alarm does not respond to the key fob. The reason for this phenomenon may be:
- Insufficient charge of the power supply of the control panel, the pulses sent over the radio channel are not able to forward the commands encrypted in packets (the old battery in the key fob is dead, the signal strength has decreased, it is time to replace the power source)
- resynchronization between system elements installed on the machine, and the control panel (you can restore the relationship by rewriting the key fobs, using the Valet service button, a step-by-step guide to this event should be found in the instruction manual).
Summarizing the above: APS alarms are the most comfortable and effective car protection against theft, one of best products this market segment. So does it make sense to look for something better?

INTRODUCTION
Congratulations on your purchase of an A.P.S. 2550! This system is designed and manufactured taking into account the wishes of our Russian customers and is characterized by simplicity and reliability in operation (which is achieved by using an industrial-type Microchip microprocessor), ease of programming (system configuration reduces the need to change the system settings to a minimum) and can be installed on almost any type of car .
In the A.P.S. 2550 has everything really necessary functions : dynamic code, built-in starter blocking relay, the ability to connect 2 more additional engine blocking circuits, a 2-level shock sensor with the possibility of separate remote zone shutdown, Valet switch, built-in relays for controlling door locks and turn indicators, 2nd channel output , the ability to control the closing of car windows and an additional pager, the ability to turn on the “turbo” mode and the security mode when the engine is running, the ability to program your personal code, the function of disarming in 2 stages, Anti-Carjacking, anti-theft protection, the “Panic” mode, a number of programmable features and much more.
Pay attention to 3 main components of your security system:
- Keychain transmitter
- System Status LED (LED)
- Valet Pushbutton Switch
1. Key fob transmitter with dynamic code
The car alarm kit includes two key fobs-transmitter with dynamic code based on the KEELOQ microprocessor. Each time you press the transmitter button, the code will automatically change randomly. Thus, your system is protected from attempts to "intercept" the code of your transmitter using a code grabber.
During operation, a situation may arise when the codes of the key fob transmitter and the main unit of the system are out of sync (for example, if you pressed the transmitter button more than 30 times away from the car). In this case, you only need to approach the vehicle and quickly press the transmitter button twice.
2. System Status LED (LED)
The LED informs the owner of the car about the state of the alarm system and indicates the zone or trigger that caused the system to go off.
3. Valet push button switch
This switch allows you to temporarily disable security functions system (transferring the system to the Valet service mode). It is also used in conjunction with the ignition key for emergency disarming the system in the event of a lost transmitter, for disabling Anti-Carjacking (see the relevant sections of this manual below), for manual arming, when programming system functions, and when programming new transmitters. .

MANUAL
1. Arming the system using a transmitter
Switch off the ignition, get out of the vehicle and make sure all doors, hood and trunk are closed. Press and release the transmitter button once. You will hear 1 confirmation siren, the turn signals will turn on 1 time and the system LED will flash slowly. The system will also automatically lock the car door, disable the starter, auxiliary circuits and automatically close the car windows (if the appropriate connections have been made and functions # 17 and/or # 19 have been programmed).
Note : Pressing the transmitter button within 30 seconds of power window output operation will stop this function without disarming the system. The next press of the transmitter button will disarm.
2. Arming the system with separate shutdown of shock sensor zones
3. Bypass faulty zone when arming
- If one of the doors, hood or trunk is not closed, or if one of these circuits is faulty, then when the system is armed using the transmitter, you will hear 3 siren sounds (instead of one) and the direction indicators will flash 3 times. This will bypass the open or faulty circuit and the LED will flash 2 or 4 times with a pause for 30 seconds (or until the circuit is restored, if earlier), indicating the faulty and bypassed circuit (door or hood/trunk, respectively).
- If the shock sensor circuit is faulty, then 5 seconds after the system is armed (or 5 seconds after the car windows are automatically closed, if this function is used), you will hear 3 more siren sounds and the direction indicators will flash 3 times. The LED will then flash in series of 3 flashes, followed by a pause of 30 seconds (or until the circuit is restored, if earlier).
- Once the bypassed arming circuit is closed or repaired, the system will arm it immediately as well.
4. Automatic (passive) system arming
5. Automatic (passive) blocking of the engine
- If for any reason you do not want to use the auto-arming feature (with or without locking the doors), you can still use the auto-engine lock feature (programmable feature #8).
- If this function is enabled, after the ignition is turned off - the system LED will begin to flash rapidly, confirming the inclusion of the countdown before switching on the mode. 30 seconds after the ignition is turned off (regardless of whether the car doors were opened and closed), the system will only automatically turn on the engine block (similar to an immobilizer), but will not lock the car doors or respond to door, hood, trunk or shock sensor inputs. . The LED will start flashing slowly.
When the system is in automatic engine lock mode:
- When the ignition is turned on, the siren will give warning signals for 10 seconds. If during this time the ignition is not turned off or the system is not disarmed, the siren will turn on for 3 minutes (or until the ignition is turned off, if this happens earlier) and the output to an additional pager will be activated (if connections have been made and function # 17 or # nineteen). After turning off the alarm mode, the system will remain in the passive engine blocking mode.
- Disconnecting and then reconnecting the power will cause the system to operate immediately. After the end of the alarm mode, the system will switch to the “full” protection mode.
To disable the enabled automatic engine blocking mode:
In the event of a lost or malfunctioning transmitter, you can also disarm the system using the Valet switch or personal code (depending on the status of feature #11).
Note : To execute the automatic passive engine lock function, the passive arming function (function #1) must be off.
6. Arming the system with the engine running
You can use the arming function while the engine is running (programmable feature #10).
Exit the vehicle with the ignition on and make sure all doors, hood and trunk are closed. Press and hold the transmitter button for 2 seconds. You will hear 1 confirmation siren, the turn signals will turn on 1 time and the system LED will flash slowly. The system will also automatically lock the car doors and automatically close the car windows (if the appropriate connections are made and functions #17 and/or #19 are programmed), but the engine will not be blocked, and the trigger inputs of the ignition circuit and shock sensor will be disabled.
Note : You can leave the keys in the ignition if the necessary connections have been made and the channel 2 functions (#17 and #18) have been programmed accordingly. With the engine running, press and hold the transmitter button for 2 seconds. The system will begin to supply power to the engine bypassing the ignition key. Remove the key from the ignition, exit the vehicle and make sure all doors, hood and trunk are closed. Press and hold the transmitter button for 2 seconds to arm with running engine.
If, when trying to arm the system with the engine running, one of the doors, the hood or trunk is open, the system will be armed won't get up and you will hear 5 short warning siren sounds.
If, in armed mode with the engine running, the ignition is turned off for more than 3 seconds, then after 3 seconds the system will switch to the standard armed mode: it will block the starter and additional circuits (if the appropriate connections have been made and functions # 17 and / or # 19 have been programmed) and again will arm the ignition circuit input and shock sensor.
In the armed mode with the engine running, when any of the doors, hood or trunk of the car is opened, or when the power is turned off, the alarm mode will immediately turn on: the system will turn on the engine blocking circuits, the siren, the direction indicators will work continuously for 30 seconds (if the ignition was turned off) and the output to an additional pager will be activated immediately (if the appropriate connections are made and functions # 17 or # 19 are programmed). If the ignition is left on, the alarm mode will continue until the ignition is turned off.
Note : Arming when the engine is running is not possible when the anti-carjacking functions(see below).
7. Arming the system with the inclusion of the “Turbo” mode
After vigorously driving a vehicle with a turbocharged engine, before shutting down the engine and arming the system, it is generally recommended to cool the turbine by letting the engine run for a few minutes. idling. The "Turbo" mode allows you to arm the system without waiting for the turbine to cool down.
ATTENTION: To implement this function, the function of arming the system with a running engine (function # 10) must be enabled, the necessary connections must be made and the output of the 2nd channel of the system must be programmed accordingly (function # 18).
8. Manual system arming
If for some reason you cannot use the key fob transmitter to arm the system and do not use the passive arming function or the automatic engine blocking function, then you can arm the system using the Valet button at any time.
ATTENTION : This function is not automatic and only runs for one cycle until the system is disarmed, so the next time the system is disarmed, you will need to use this function again to arm the system without the aid of a transmitter.
For manual setting systems to arm - open the car door (the hood and trunk must be closed), turn off the ignition, briefly press and release the Valet button switch once and then press and hold the Valet button switch for 3 seconds until 1 short siren beep. Close the car door and after 5 seconds the system will automatically arm: you will hear 1 confirmation siren, the turn signals will turn on 1 time and the system LED will flash slowly. The system will also automatically lock the car door, block the starter and auxiliary circuits, and automatically close the car windows (if the appropriate connections are made and functions # 17 and/or # 19 are programmed).
Note : If after manual arming you hear 3 siren sounds and the direction indicators turn on 3 times, this means that the shock sensor is active or defective.
9. Operation of the system when the protection is on. Warning mode.
- If the car body is slightly bumped or hit, the warning mode will turn on and the siren will give 5 quick warning signals.
- If the impact is more severe, when you open the door, hood or trunk, when you try to turn it on or when you turn off the power to the system, the alarm mode will immediately turn on: the siren, the direction indicators will work continuously for 30 seconds (or until you turn off the alarm mode with transmitter) and the output to an additional pager will be immediately activated (if the appropriate connection is made and function # 17 or # 19 is programmed). If all doors, hood and trunk are closed after 30 seconds, the system will automatically re-arm. If one of the circuits remains open, then the 30-second cycle of the alarm mode will be repeated. However, after 5 cycles (excluding ignition ON) the siren and turn signals will turn off and the system will arm bypassing the open circuit. Once the bypassed circuit is closed, the system will also automatically arm it immediately. If the system is triggered by turning on the ignition, there will be no limit to the number of alarm cycles and the alarm mode will continue as long as the ignition remains on.
When the system worked:
- pressing and releasing any of the transmitter buttons once before the end of the 30 second alarm mode cycle will only end the alarm mode, but the system will remain armed. In this case, if one of the circuits remains active (open), then the siren will give 3 warning signals and the direction indicators will flash 3 times.
Note : if the system was triggered by an attempt to turn on the ignition and the ignition remained on - the alarm mode cannot be turned off from the transmitter, you must first turn off the car's ignition.
Note : Disabling the alarm mode when the ignition is left on is not possible.
10. Anti-false alarm function
In order to minimize false alarms of the system and not disturb others, you can use the programmable anti-false alarm function (feature # 9). When this feature is enabled:
- If the shock sensor warning zone is triggered 10 times within 30 minutes, that system input will be automatically disabled for 1 hour (or until the system is disarmed, if earlier).
- If the main shock sensor zone is triggered 5 times within 60 minutes, this system input will also be automatically disabled for 1 hour (or until the system is disarmed, if earlier).
Disabling the various zones of the shock sensor occurs independently of each other.
ATTENTION : Disabling shock sensor zones will be immediately canceled when the system is triggered by opening a door, hood or trunk.
11. Disarming the system. Automatic re-arming of the system.
If the sensor circuit is faulty, then 5 seconds after the system is automatically armed, you will hear 3 additional siren sounds, the direction indicators will flash 3 more times and the sensor circuit will be bypassed.
12. Silent arming and disarming the system
ATTENTION : When the system is silently armed or disarmed, the 3rd and 4th chirps (Open or Faulty Circuit Warning and System Triggered Warning) will not be silenced.
13. 2-step AVP - disarming the system in 2 steps
The 2-stage disarming function (programmable function # 12) allows you to further increase the anti-theft protection of your car both from attempts to disable the security system using various electronic devices (such as the “409” device) and from stealing your car keys with a key fob system transmitter.
If programmable feature #12 is enabled, then after disarming the system by pressing the transmitter button, the system will give standard confirmation tones, unlock the vehicle doors and disable the system triggers, however, the vehicle engine will remain blocked. To disable the engine interlock circuits - Turn the ignition on and, within 15 seconds, press and release the Valet push button switch once, or enter your personal system disable code (depending on the status of programmable feature #11). You will hear 2 siren sounds and be able to start the car engine.
ATTENTION : this function cannot be implemented when disarming with the engine running.
14. System warning
If, when disarming the system, you hear 4 siren signals, this means that the system was activated during your absence. The LED will flash a certain number of times after a pause, showing which circuit triggered the system:
- if the system was triggered by a door trigger, by turning on the ignition or by turning off the power - the LED will flash in series of 2 flashes after a pause;
- if the system was triggered by the main zone of the shock sensor - the LED will flash in series of 3 flashes after a pause;
Information about the operation of the system will be erased when the ignition is turned on or when the system is armed using the transmitter.
15. Automatic door locking when the ignition is turned on
If function #3 is enabled, the system will automatically lock the car door 5 seconds after the ignition is turned on to ensure your safety while driving. At the same time, if one of the doors is opened and closed again within 5 seconds after the ignition is turned on, this function will be canceled so that you cannot accidentally lock the keys in the car.
16. Automatic unlocking of doors when the ignition is turned off
If feature #4 is enabled, the system will automatically unlock the vehicle doors immediately after the ignition is turned off.
This function is programmable and you can disable it at the request of the client. The programming procedure is described in the Programmable System Functions section.
17. Door lock/unlock control via transmitter
When you press the transmitter button with the ignition on, the system will lock the car doors. When you press the transmitter button with the ignition on, the system will unlock the car doors.
18. Central locking function
If the necessary connections have been made and function #16 has been programmed accordingly, the system will also be able to function as a central lock. When manually locking or unlocking the driver's door, all other doors will also automatically lock or unlock, but only when the system is disarmed.
If you want to use this feature, please contact your installer.
19. 2nd channel output
The output of the 2nd channel of the system can also be turned on when the system is armed, in which case the system will simultaneously turn off the shock sensor and the hood/trunk trigger for a while so that opening the trunk does not trigger the system. 3 seconds after the trunk is closed, the system will automatically arm these circuits again.
- The 2nd channel output of the system can also be used to control various other auxiliary devices. The operating mode of the channel 2 output of the system in this case can be programmed at system installation (programmable function No. 18) as
The output of the 2nd channel of the system can also be programmed during installation to perform additional security or service functions, such as, for example (programmable function # 17):
- exit for closing car windows;
- output for additional blocking of the engine;
- output for controlling an additional pager;
ATTENTION : Please note that in this case the 2nd channel output of the system will no longer be controlled by the transmitter and will always execute only that selected alarm or service function. Check with your installer for the function performed by the system's 2nd channel output.
20. Valet Mode
Valet mode is used to temporarily disable the security functions of the system (service mode). Valet mode is retained when the system is powered off and then back on.
Enabling Valet Mode:
- Disarm the system and turn on the ignition
- The LED will turn solid, indicating that the system is in Valet mode.
ATTENTION : When the system is in Valet mode, each time the ignition is turned off, the siren will sound 2 short beeps to remind you that the security functions of the system have been disabled. Don't forget to turn off Valet mode when you no longer need it so that your car is not left unprotected!
Turn off Valet mode:
- Turn on the ignition
- Within 15 seconds, press and hold the Valet push button switch for 2 seconds.
- LED will turn off
When the system is in Valet mode, you can unlock and lock the car doors using the transmitter, turn on the Panic mode, and control the system's 2nd channel output.
21. Emergency shutdown of the system. Personal system shutdown code.
Function emergency shutdown The system can be used if you have lost or forgotten your key fob transmitter, or if the key fob transmitter is not functioning properly (for example, the battery is dead), as well as to disable the Anti-Carjacking mode (see below).
The method of shutting down the system depends on the state of programmable feature #11: shutting down the system is done by pressing the Valet pushbutton or by entering your personal shutdown code. Your personal system shutdown code can be any single digit from 2 to 9, the procedure for programming a personal code is described below in the “Programmable System Features” section.
System Emergency Shutdown with Valet Pushbutton Switch (Feature #11 Enabled)
- Turn on the ignition.
- Within 15 seconds, press and release the Valet push button switch.
- The alarm mode will turn off and the system will be disarmed.
Emergency shutdown of the system using a personal code (feature # 11 disabled)
- Open the car door. The system will work, the siren will sound immediately, the direction indicators will flash, etc.
- Turn on the ignition.
- Within 15 seconds, press and release the Valet pushbutton a number of times equal to your programmed personal code.
- If the correct personal code is entered, after a few seconds the alarm will turn off and the system will be disarmed.
22. Panic Mode
Panic mode is activated by pressing and holding the buttons and the transmitter simultaneously for 2 seconds while the vehicle ignition is turned off. When this mode is activated, the system siren will sound continuously and the direction indicators will flash.
To turn off the panic mode, press any button on the transmitter. The siren will turn off and the direction indicators will stop flashing. After turning off the Panic mode, the system will return to the state prior to the moment when the Panic mode was turned on.
The "Panic" function can also be implemented while the system is in the "Valet" mode, but only when the ignition is off. After turning off the “Panic” mode, the system will switch back to Valet mode.
23. Anti-theft function Anti-Carjacking
The Anti-Carjacking function is activated by pressing and holding the buttons and the transmitter simultaneously for 2 seconds while the car's ignition is on. The system LED will flash slowly.
30 seconds after turning on the Anti-Carjacking mode, the direction indicators will flash and the system siren will sound. If the ignition is turned off at any time after the activation of the Anti-Carjacking mode, the system will immediately block the car engine.
If the Anti-Carjacking mode has not been disabled, then after another 30 seconds the system will turn on the engine blocking circuit.
After 3 minutes, the siren and direction indicators will turn off and the system will arm - if at this moment the ignition key is in the “Off” position.
If the ignition key remains in the “On” position, the siren and direction indicators will continue to work until the battery is completely discharged and the output to an additional pager will be activated (if the appropriate connection is made and function # 17 or # 19 is programmed)

Factory setting function #12 - DISABLED
Feature #13:“45 second delay before arming”
Factory setting function #13 - DISABLED
On many modern vehicles, interior lighting turns off some time after the doors have been closed. If the door trigger circuit is connected to the wire from the door limit switch to the interior light bulb, the system will then "think" that the car door is open. In order to avoid similar situation, You can enable the system's 45-second delay arming function, and then the system will arm the car doors after the interior lights are turned off.
ATTENTION : When this feature is enabled and if one of the doors is open when the system is armed from the transmitter, the system will not be able to indicate this with 3 siren sounds and will bypass the circuit without arming it. However, after 45 seconds, if the door is left open, the siren will sound 3 times and the turn signals will flash 3 times, confirming that the door trigger input has been bypassed. The system will arm this circuit 3 seconds after all doors are closed again.
Feature #14:“Display of the number of programmed transmitters of the system”
Factory setting function #14 - DISABLED
If programmable function # 14 is enabled, then each time after the ignition is turned on with the system disarmed - the system LED will flash for 10 seconds in series of 1 ... 4 flashes, indicating the number of programmed transmitters.

Feature #15:“Output pulse duration for door lock control”
The factory setting of function # 15 is 0.8 s.
ATTENTION
The type and duration of the impulse for locking and unlocking the doors can be programmed as follows: 0.8 s. (locking and unlocking, factory setting); 3.5 s (locking and unlocking); double locking pulse of 0.8 s (unlocking - a single pulse of 0.8 s); “Comfort” mode (locking impulse 20 s only when the system is armed using a transmitter, unlocking impulse 0.8 s). To select the desired duration of the door lock control pulse, press the transmitter button 1, 2 or 3 times (the siren will give 2, 3 or 4 confirmation signals, respectively).
Note: If the Comfort mode is enabled, the shock sensor of the system will be automatically disabled for the duration of the 20 second lock pulse plus an additional 3 seconds. Pressing the transmitter button again within 20 seconds after arming the system reduces the duration of the pulse and after 3 seconds. restores the operation of the shock sensor.
Feature #16:“Implementation of the central locking function”
The factory setting for feature #16 is OFF.
ATTENTION : This feature should only be programmed by a qualified installer when installing the system.
You can program one of the unused system inputs: "+" door trigger (Purple wire of the system) or "-" trigger of the door (Brown wire of the system) to connect to a 5-wire motor in the driver's door to implement the "central locking" function when the mode is off protection. In armed mode, this input of the system will still act as a zone of protection, and when this input is activated (an attempt to raise the door motor to open the door), the alarm mode will immediately turn on.
Using this function will allow you to implement the “central locking” function without the need for an additional module, it will be enough just to install one 5-wire electric actuator in the driver's door and 2-wire electric actuators in the remaining doors. After that, when locking or unlocking the driver's door, the system will automatically lock or unlock all vehicle doors.
To program the system's Purple wire (“+” door trigger) as a “+” input for connection to the 5-wire motor in the driver's door, press and release the transmitter button. The siren will give 2 beeps.
Press and release the transmitter button 2 times to program the Brown wire of the system (“-“ door trigger) as “-” input for connection to the 5-wire motor in the driver's door. The siren will give 3 beeps.

APPENDIX
CONNECTING THE VEHICLE DOOR LOCKS
NEGATIVE PULSE CONTROLLED 3-WIRE CENTRAL LOCKING CIRCUIT
YELLOW/BLUE and YELLOW/GREEN wires must be connected to ground.
Connect the WHITE/GREEN wire (negative lock pulse) to the vehicle's negative lock wire.
Connect the WHITE/BLUE wire (negative unlock pulse) to the vehicle's negative unlock wire.
POSITIVE PULSE CONTROLLED 3-WIRE CENTRAL LOCKING CIRCUIT
Vehicles with these circuits do not use the RED/GREEN and RED/BLUE wires.
YELLOW/BLUE and YELLOW/GREEN wires must be connected to +12V direct current through the fuse
Connect the WHITE/GREEN wire ( positive momentum lock) to the vehicle door lock positive wire.
Connect the WHITE/BLUE wire (positive unlock pulse) to the vehicle's positive unlock wire.
5-WIRE REVERSE CENTRAL LOCKING CIRCUIT
In cars with such circuits, it is necessary to find regular wires going from the main door lock switch located next to the driver, to the lock switches on the passenger doors, and then to the electric locks.
Cut the original lock wire and connect the YELLOW/GREEN wire to the part of the wire that comes from the passenger door switch or the power and connect the RED/GREEN wire to the other part of the wire that comes from the main switch.
Cut the original unlock wire and connect the YELLOW/BLUE wire to the part of the wire that comes from the passenger door switch or the power switch and connect the RED/BLUE wire to the other part of the cut wire that comes from the main switch.
The WHITE/BLUE and WHITE/GREEN wires must be connected to +12VDC via a fuse.
“VACUUM” CENTRAL LOCKING SYSTEM
Mercedes-Benz or Audi cars use a "vacuum" central locking system. It has electrical switches (built into the pneumatic actuators) that supply +12V or ground to the pneumatic pump. These switches work when locking and unlocking the doors from inside or with the key from outside the vehicle. The polarity of the switches determines whether the pump will pressurize or vacuum. The connection can be made either under the trim (panel) to the left of the driver, or directly on the air pump, which is usually installed in the trunk or under the rear seat.
Connect the RED/GREEN and YELLOW/BLUE system wires to each other and insulate the connection.
Connect the WHITE/BLUE system wire to +12V through the fuse.
Connect the WHITE/GREEN wire of the system to ground.
Cut the wire from the electrical switch to the air pump (compressor). Connect the RED/BLUE wire from the system to the part of the cut wire that goes to the electrical switch.
Connect the YELLOW/GREEN wire from the system to the other part of the cut wire that goes to the air pump (compressor).
ATTENTION : On 1989 (or earlier) vehicles, the air pump runs for about 3 seconds. When installing the system on such vehicles, it will also be necessary to program the duration of the pulse applied to the door locks to 3.5 seconds (function # 15).
1-WIRE SYSTEM WITH NEGATIVE POLARITY
If the car is Nissan, Mitsubishi or Lotus and there is no switch in the door, you need to find the wire coming from the driver's door, which is shorted to ground if the car doors are open, and “open” (0V) if the doors are closed.
This type of vehicle does NOT use the WHITE/GREEN and RED/BLUE system wires.
Connect the WHITE/BLUE wire of the system to ground.
Cut the wire from the driver's door motor to the OEM central locking module and connect the system's RED/GREEN wire to the part of the cut wire that goes to the driver's door motor.
Connect the YELLOW/BLUE and YELLOW/GREEN wires of the system to the other part of the cut wire that goes to the original central locking module.
INSTALLATION OF ADDITIONAL ACTUATORS
If the vehicle is not equipped with central locking or power door locks, you can install additional power controls and connect them to the system as follows:
Connect the RED/GREEN and RED/BLUE wires to ground.
Connect the WHITE/GREEN and WHITE/BLUE wires to +12 DC through the fuse.
Connect the YELLOW/BLUE wire to the BLUE actuator release wire.
Connect the YELLOW/GREEN wire to the GREEN wire to lock the actuator.
DOUBLE PULSE LOCK / COMFORT FUNCTION
- The standard central locking systems of some recent models of cars require a double negative pulse signal to activate the door lock after they are locked (the “re-locking” pulse). In this case, function #15 must be programmed accordingly.
- A number of modern cars are equipped with a standard "Comfort" system, which locks all doors and closes all windows and the sunroof when the driver's door lock is locked with a key and held in the lock for a certain time.
If function #15 is programmed accordingly, when the system is armed with a transmitter, the system will generate a lock pulse for 20 seconds. For this period of time, the system will also automatically input the shock sensor. In all other cases (when disarming the system, during passive arming, automatic re-arming, etc.), unlocking and locking pulses with a duration of 0.8 s will be given.
Pressing the transmitter button while the Comfort function is active will stop this function.
CONNECTIONS FOR THE “CENTRAL LOCKING” FUNCTION
- If the vehicle uses door switches negative polarity, program the Purple wire of the system as “(+) input for 5-wire motor connection” (programmable feature #16). In this case, when the Purple wire is shorted to +12 V, the system will automatically send a pulse to unlock the car doors, and when disconnected from +12 V, the system will automatically send a pulse to lock the car doors, but only when the security mode is off. When armed, shorting the Purple wire to +12V will only cause the system to immediately trigger and re-lock the doors.
Among the wires of the 5-wire electric drive installed in the driver's door, find the wire corresponding to the common contact of the contact group built into the electric drive. Connect the purple wire of the system to it. Then find the wire that closes with the common wire of the built-in contact group when the door is not locked. Connect this wire to the vehicle's +12V DC power supply. Insulate the third wire of the built-in contact group.
- If the vehicle uses positive door limit switches, program the Brown wire can also be programmed as “(-) 5-wire motor input” (programmable feature #16). In this case, when the Brown wire is shorted to ground, the system will automatically send an impulse to unlock the car doors, and when disconnected from the ground, the system will automatically send an impulse to lock the car doors, but only when the security mode is off. A brown wire to ground will only cause the system to immediately activate and re-lock the doors.
Among the wires of the 5-wire electric drive installed in the driver's door, find the wire corresponding to the common contact of the contact group built into the electric drive. Connect the brown wire of the system to it. Then find the wire that closes with the common wire of the built-in contact group when the door is not locked. Connect this wire to vehicle ground. Insulate the third wire of the built-in contact group.
CONNECTING THE ELECTRIC TRUNK LOCK TO THE 2nd CHANNEL OUTPUT OF THE SYSTEM (see programming function # 17)

CONNECTION TO IMPLEMENT THE FUNCTION OF CLOSING THE VEHICLE WINDOWS WHEN ARMING
If the vehicle is equipped with power windows, then you can use the Blue wire of the system or the Orange/Black wire of the system as a "negative output to close the car windows when the system is armed". To do this, program function #17 (when using the Blue wire) or function #19 (when using the Orange/Black wire) accordingly.
When using the Blue wire to implement this function, this system output will no longer be shorted to ground when the transmitter button is pressed and held for 2 seconds. Instead, the Blue wire will short to ground for 30 seconds after the system is armed.
Pressing the transmitter button within these 30 seconds will disable that system output (the system will remain armed). In order to prevent the operation of the power windows from triggering the system, the system will automatically disable the shock sensor input for as long as this output is activated + 3 seconds more.
Locate the wire of the car's standard power window control module, when shorted to ground, the windows close. Connect the Blue (or Orange/Black) system wire to this wire.
You can use the Blue wire of the system to have the system supply power to the ignition switch for a certain amount of time. In this case, you will be able to arm the system with the engine running without leaving the keys in the ignition (if programmable feature #10 is enabled).
To implement this function:
- The Orange/Black wire of the system MUST be used to block the ignition circuit.
- Program the 2nd channel output of the system (Blue wire) as “permanent” (function # 18);
- Connect terminals #86 and #30 of the relay to a wire from the ignition switch that has +12V when the ignition key is in the ON and CRANK positions and 0V is present when the ignition key is in the any other position. Terminal #86 of the relay must be connected to this wire AFTER the connection to the optional ignition interlock relay.
- Connect relay pin #87 to +12V DC power through a fuse.
|
|
CONNECTION FOR IMPLEMENTATION OF THE ARMING FUNCTION WITH THE ENGAGEMENT OF THE “TURBO” MODE
You can use the Blue wire of the system to enable turbo mode when installing the system on a vehicle with a turbocharged engine. To implement this function:
- Enable programmable feature #10 (possibility of arming the vehicle with the engine running).
- Program the system's 2nd channel output (Blue wire) as “timed 180 second” (feature #18).
- Connect the Blue wire of the system to terminal #85 of the auxiliary relay.
- Connect terminals #86 and #30 of the relay to a wire from the ignition switch that has +12V when the ignition key is in the ON and CRANK positions and 0V is present when the ignition key is in the any other position. Terminal #86 of the relay must be connected to this wire AFTER the connection to the optional ignition interlock relay. Connect relay pin #87 to +12V DC power through a fuse (as shown in the diagram above).
Below is a wiring diagram for the Orange/Black wire to block the ignition circuit using an optional N.C. relay. Orange/Black wire must be programmed as “negative output when armed to control additional N.C. engine blocking relay” (programmable function No. 19).
|
|
Note : this circuit can also be used to connect the Blue wire of the system, for this the Blue wire must be programmed as “negative output when armed to control an additional N.C. Engine Interlock Relay" (programmable feature #17).
When using the Blue wire to implement this function, this system output will no longer be shorted to ground when the transmitter button is pressed and held for 2 seconds. Instead, the Blue wire will automatically short to ground each time the system is armed and will remain in that state until the system is disarmed.
You can use the Blue system wire or the Orange/Black system wire as "negative output to control the optional pager". To do this, program function # 17 (when using the Blue wire) or # 19 (when using the Orange/Black wire) accordingly.
When using the Blue wire to implement this function, this system output will no longer be shorted to ground when the transmitter button is pressed and held for 2 seconds. Instead, the Blue wire will automatically short to ground when the system is triggered.
Connect the Blue (or Orange/Black) wire of the system to the negative trigger wire of the auxiliary pager. If the pager is driven by a positive trigger, use an additional relay as shown in the diagram.

| Slavik(www.citilink.ru/) Normal signaling, it's the most for the Zhiguli classic. Worked without glitches, and probably now works for the current owner. Installed it myself, no problems. I especially like that the siren does not work immediately, but gives a warning signal. |
Andrei(www.citilink.ru/) I can say that the APS 2550 and in general all the signaling of this brand are extremely unstable. The main glitch is that the key fob sticks. The signal is also weak from the 4th floor, barely opens. Of course, it is difficult to expect something from such a cheap thing, but in my opinion it is better not to be greedy and install something more adequate. |
| Maxim(avtogsm.ru) I am personally satisfied with the APS 2550. Pretty normal alarm. The door opens and closes, the key fob obeys, it doesn’t work in vain. Yes, there is no auto-ignition and feedback. But at this price? What else to expect? |
Vasiliy(avtogsm.ru) I had one like this on the Priore. I'm glad I got rid of that alarm. She constantly worked, the neighbors were already making comments. Tried to adjust the shock sensor - all in vain. Replaced with a new Tomahawk - a completely different matter! |
| Pavel(AutoSvit) For those who have a car under the windows in the yard, the APS 2550 car alarm is perfect. If the car is in the access zone, the main thing is that the siren yells if something happens. Why overpay for two-way communication? |
Oleg Turchak(AutoSvit) Bought a car with this alarm. At first it worked fine, and then it began to block the engine. I get up in the morning, but I can’t leave for work, the car doesn’t work. I have already studied the instructions, tried the Jack button, nothing happens. The guys at the service seem to have removed this setting, but after a while it started again. In short, some kind of glitch in the system, I had to remove it and buy a new one. |
Drawing conclusions
After a careful study of the capabilities of the APS 2550 car alarm, and the feedback of the real owners of this system, we can conclude that it is able to provide all the basic car security functions. Namely:
- Response to contact with shock sensor
- Alert the owner of the danger with a loud sound and light signal
- remote control
- The presence of several modes (including programmable)
- Blocking code grabbers that allow criminals to steal a car
As practice shows, these five simple functions in most cases, it is enough to ensure the safety of the vehicle.
With proper connection and normal conditions operation, the alarm rarely fails and works quite reliably. All this makes the APS 2550 an acceptable security option for low-cost car owners. It is able, if not to completely protect the car, then at least several times to reduce the risk of theft or robbery.
