How to adjust the sensitivity of the starline alarm

Most often, random activation of the StarLine alarm is associated with incorrect settings of the shock sensor. The fact is that the name “shock sensor” itself is incorrect - it is a vibration sensor, so it also responds to strong noise, road vibrations from passing trucks, and so on.

Modern two-level shock sensors (like other alarm sensors in car security systems) have two separately adjustable levels:

1. Warning level: as soon as the vibration recorded by the sensor exceeds a preset level, a short-term siren signal is activated, and the corresponding information is supplied to the key fob.
2. The alarm level is set higher than the warning level. In this case, the siren turns on constantly, all interlock circuits are activated, and instead of a single signal and short-term vibration, the key fob transmits signals periodically.

A properly configured and installed (this is no less important) shock sensor does not cause serious problems, and occasionally it has to be reconfigured (for example, if construction begins next to the parking lot).

What to do if the shock sensor triggers for no reason

The most common problem that owners of an alarm system from Starline with a shock sensor encounter is a false alarm.
It occurs even in devices that have been installed recently. As a result, the sensor goes off on its own and the alarm screams, although no one is nearby. To fix the problem, the first thing you need to do is figure out what the warning signs were for the appearance of a false signal. Did this happen at a time when other people's cars were passing nearby? Or during certain weather events.

The time of day when such incidents occur plays a role. And also how often they happen. In some cases, false alarms occurred when the car's handbrake was engaged. To accurately determine the reasons, all details are important.

Another problem is a violation of the design of the sensor or module associated with external damage or wear. Replacing or repairing broken parts will help fix the problem. The signal is also triggered due to the interception of radio waves when the module and sensor loops are close to each other. To eliminate it, just separate them.

If the sensor is constantly disconnected, then the reason may lie in improper mounting. For the latter, I use plastic, which is deformed and destroyed due to impacts or other external influences. The plastic mount can be replaced with a metal one.

The best way to test the serviceability of newly installed sensors is to test at minimum sensitivity. If a reaction is observed even with minimal settings, then the system will probably need to be replaced.

Signal sensors

To accurately trigger the Starline A 91 alarm, it is necessary to fine-tune the trigger modes of the shock sensor in the event of an unauthorized attempt to gain access to the car by unauthorized persons.

Modern alarm systems are equipped with 3 types of sensors installed on cars:

• a shock sensor, which is triggered by vibration of the car body when a set threshold value is exceeded;
• movement sensor, gives a signal when there is an attempt to steal or evacuate a car;
• volume sensor, is triggered when an attempt is made to enter the vehicle interior.

Correct configuration of sensors ensures reliable vehicle security and eliminates false alarms.

With more modern alarms, adjustment is carried out somewhat differently.

So for the starline car alarm model A93, the process of adjusting (decrease or increase) the sensitivity of the alarm is as follows:

• first of all, as noted above, you should find the shock and movement sensor itself;
• The maximum sensitivity level of such a sensor is determined by the value 14. It can be reduced to 01.

Alarm functionality

Alarm Starline A 91 is a modern alarm system widely used by car owners to protect their cars in Russia. The system is equipped with a two-level shock sensor, which is triggered by external impact on the vehicle by emitting a sound signal and transmitting an alarm signal to the owner. To protect against random electromagnetic interference, special protection has been installed to protect against false alarms. The Starline security system is built on two-level zone protection of an object and provides for mandatory adjustment after installation on the vehicle.

Features of the Starline A 91 car alarm:

• high sensitivity of the “friend or foe” response system;
• low sensitivity to radio interference;
• control of the vehicle autostart system using various modes;
• special key fob protection;
• equipping the key fob with a battery that ensures long-term operation;
• stable operation of the system in climatic conditions from -45* to +85*C.

The Starline system is controlled using two key fobs with a range of 600 meters.

How to reduce alarm sensitivity

Operating and setting instructions for the Starline A93 alarm system

Among the pressing problems associated with car alarms, there is often a need to deal with its excessive sensitivity. Sometimes the alarm sensitivity is adjusted in such a way that if you just jump next to the car, the security siren will immediately turn on

This is not a completely normal situation, since you will have to pay attention to the car every time, and your neighbors will not say “thank you” for this

Therefore, if this problem is relevant to you, today we will learn how to reduce the sensitivity of the alarm.

Let's take the Starline alarm system as an example.

If we consider why the alarm goes off all the time, then we can note only two reasons:

• The starline a91 alarm sensitivity setting is set to maximum;
• The shock sensor and the alarm unit are poorly secured, resulting in a false alarm of the siren.

How to reduce the sensitivity of the starline alarm?

If the problem occurs due to the first reason, then you need to act as follows:

1. If you have a standard car alarm installed, look in the service book where the control unit and shock sensor are located.
   If the alarm system was installed additionally, you will have to work hard to find the controls. For example, you can navigate by the Valet button, look where the wires go from it. As a rule, the control unit is mounted in the area of ​​the pedal assembly. Did you manage to find the location of the block? Great, let's move on...
2. To reduce the sensitivity of the alarm, you need to find a control element on the unit that is responsible for this function. By the way, the shock sensor can be integrated into the unit, or be a separate element. Set the sensitivity to a position slightly above average, do not reduce the sensitivity level to 4-5 units, in this case the car alarm may not work correctly, or the sensitivity will be very weak and the alarm will not give a signal if someone decides to mutilate your car.

As we have already said, sometimes the problem of frequent activation of the siren may not be due to the high sensitivity of the alarm. The cause may be an incorrect or poorly secured control unit, or a shock sensor. To find out if this is causing the problem, you will also need to locate the sensor and control unit.

The sensors must be screwed to a solid surface and not dangle, much less hang.

Connecting the key fob

For the Starline A 91 alarm to work correctly, it is necessary to connect the key fob to the vehicle’s electronic security system.

Connection is made in the following sequence:

1. To carry out the registration process, you need to find the “Valet” button (in the fuse box, under the steering wheel or glove compartment) and press it 7 times to activate the system with the engine off.
2. Turn on the ignition. The siren should sound 7 times if all operations are completed correctly.
3. To do this, we activate the key fob at the same time, press buttons 2 and 3, as a result of which one siren signal should sound, signaling that the key fob is connected.
4. We connect the second key fob in the same sequence.

The correct operation of the Starline alarm is influenced by 3 main reasons;

• adjusting sensor sensitivity;
• installation location;
• correct fastening of sensors and signal unit to the car body.

The sensitivity of the sensors can be adjusted using the control unit.

How to setup

AllAboutValet auto button on starline alarm system

The operating parameters of the piezoelectric element are adjusted by rotating the regulators clockwise with a screwdriver. There are explanatory symbols on the device body indicating the direction of rotation when the response threshold increases or decreases. Additional red and green LEDs allow you to visually determine the moment of operation when setting up the Starline A91 shock sensor.

On the A93 complex, sensitivity can be adjusted through a control panel equipped with a display and a 2-way communication unit. Additional settings are made when programming automatic start, allowing you to ignore vibrations from a rotating starter or a running power unit.

To adjust the sensitivity of the sensor on the A93 or A63 complexes, you must perform the following steps:

1. Turn off the security mode and the ignition, and then press the button located next to the key with a circle icon.
2. After receiving signals on the car, the sirens will sound 2 times and the external light alarm will flash three times. The key fob will play a melody, and an indication of the programmed level of the sensor warning zone will appear on the top of the display. Level 10 is programmed from the factory, the user sets the parameter in the range from 0 (off) to 14 (maximum). To change the number, use the buttons marked with triangle icons.
3. To proceed to adjusting the alarm level, press the button mounted next to the button with the circle logo until the sound signal sounds. Then you need to briefly press the button again. After the light signal and melody are given, the current sensitivity value appears on the display (05 at factory setting). The adjustment is made in the same way.
4. Save the settings by pressing until the beep and then briefly pressing the button used to start programming again. The processing unit will confirm the successful completion of the procedure by giving a triple signal from the external lighting lamps and a double beep from the siren. Additionally, a melodic signal is given by the control panel buzzer.

How to reduce the sensitivity of the Starline alarm

To reduce the sensitivity on the A93 or A63 complexes during autostart, you will need to perform the following steps:

1. Turn off the ignition, and then press the button to enter the menu 5 times, which is used to configure the Starline alarm. Turn the key in the lock, activating the ignition circuits.
2. Using keys with triangle symbols, select the SF section, which is responsible for adjusting additional channels.
3. Select the channel responsible for the operation of the power unit, and then long press the button located near the key with a circle icon. After the signal is given, the button is released and then pressed briefly again.
4. Using the buttons with a triangle symbol, function 3 is selected. To select a mode value, use the security button, which scrolls through the possible options in a circle. The design of the security system allows you to temporarily reduce sensitivity while the engine is running or completely turn off the sensors. The correctness of the settings is checked during test starts and engine warm-ups.
5. After programming the required parameter, you need to press long and then briefly on the key used when entering the settings of the additional channel.
6. To finally exit, you will need to turn off the ignition. After 3 flashes of the light signal, the remote control display will show the value of the programmed function. After playing the melody, the key fob goes into standard mode with an indication of the current time.

How to increase sensitivity

It is possible to adjust the sensitivity of the A91 alarm using the following algorithm:

1. Turn the regulators fully counterclockwise.
2. Adjust the warning level by turning the corrector 1/3 of the way. The setting is made with the driver's door open and the security mode turned off.
3. The owner periodically checks the force on the body at which the shock sensor is triggered. The threshold is determined by applying light blows to the central pillar or roof of the body. To check, you need to activate the security mode and wait 15-60 seconds (depending on the settings) for the sensor to turn on
4. Set an alarm level using a similar algorithm. When changing the alarm sensitivity setting, remember that the warning zone value should not exceed the alarm level parameter.

General provisions for setting up the system

To do this, you need to find a specific position for installing the shock sensor. The instructions state that the manufacturer recommends integrating the recognition system into the base of the steering column. The sensor is equipped with two fine adjustment mechanisms that allow you to adjust the sensitivity. To do this, use a standard Phillips screwdriver. To decrease the indicator, the mechanism turns to the left, and to increase, respectively, to the right.

The reasons for the constant alarm activation are:

• The default alarm sensitivity settings are set to the extreme maximum.
• Poor fixation of the alarm unit and shock sensor. To solve the problem, you need to re-secure them to a hard surface. They should not dangle or hang.

How to reduce the sensitivity of the Starline A94 alarm

For example, the selection of item No. 15 will be confirmed by 3 long signals, and the selection of item No. 17 by 3 long and 2 short signals.

The permissible number of presses is from 1 to 17. If the service button is pressed more than 17 times, the system will emit 4 short warning sounds and remain in the programming menu. If no parameter is selected within 10 seconds after entering the programming mode, the system will emit 4 long warning beeps and return to normal operation.

1. To determine the current state of the selected parameter, wait for the sound signals to be issued, the number of which will correspond to the parameter value: one short signal - on, two short signals - off.

Determining alarm sensitivity and adjusting the sensor

The two-level sensor installed by default in the Starline system operates on the so-called piezo effect. The sound wave reaches the body of the car even before the impact. This is ensured only by tightly fastening the sensor to a metal element directly connected to the body. To adjust the sensitivity, both zones are reduced, but the warning zone located opposite the green indicator is added. After that, the car is set to security mode and after 40 seconds you need to carefully hit the body.

This action will indicate the level of sensitivity - if it is excessive, then it must be reduced. The same procedure is carried out to establish a full alarm zone. The maximum sensitivity indicator of the alarm and warning indicators of the shock sensor corresponds to the value 14. The minimum indicator (coarsening) is 0.1. A value of 0 disables the shock sensor completely.

Working principle and functions

The A91 car alarm system includes a special piezoelectric sensor, which is attached to the metal panels of the vehicle body. The A93 model began to use a 3-axis accelerometer integrated into the transceiver unit. The sensor detects shocks that occur when attempting to enter the vehicle interior or dismantle parts (for example, wheels). The sensor reacts to external disturbances and sends a signal that triggers the alarm.

The user can independently configure the sensor on the Starline A91 or A93 alarm system by adjusting the warning and alarm level threshold. On early alarm models, adjustment is made by rotating a mechanical regulator; on later modifications (with an accelerometer), electronic adjustment was introduced. Depending on the settings of the parameters, the force of impact is determined at which the security complex gives a warning signal with a siren or activates the alarm mode.

Review of car alarm StarLine A93

Thanks to a special modern CAN + LIN module, the installation of the A93 security complex itself is simplified. The functionality of the system on cars is significantly expanded. An excellent choice for the domestic auto industry, with the characteristic lack of digital buses on vehicles. If desired, the device can be easily configured yourself, although it is better to entrust this to professionals. The same applies to StarLine A91.

The difference from previous analogues is the recognition of any attempts to break into the car and do something with it. Thanks to modern sensors, the owner can even know when the vehicle is about to be towed. The Starline alarm system lets you know automatically.

Special attention to the key fob with shockproof complex. The main control has an informative display that provides all the necessary information, including information on the previous version of Starline A91.

The alarm works without problems using a timer and temperature sensors. This is especially convenient when certain engine characteristics need to be maintained at a specific level. The system automatically turns off all power if attackers try to hack the vehicle while it is warming up and working with standard programs.

The vehicle's location can be tracked using maps after connecting GPRS or GLONASS modules at the owner's choice.

This will also help if the car is stolen. The main thing is to conduct several tests in advance to understand what operating mode and alert level will be successful. This is what they do when owning Starline A91.

General setup principles

If, due to the causeless howling of the siren and the ringing of the key fob, you have to get nervous too often, it’s time to start reducing the sensitivity of the car alarm, including. and starline. The general principles of this simple procedure are approximately the same for different alarms:

• carefully read the technical instructions attached to this car alarm;
• carefully study the section regarding adjusting the shock sensor;
• determine the location of the faulty sensor and the “jack” button;
• remove the car from security;
• if it is possible to change the car alarm settings, incl. and starline by reprogramming method, then perform the prescribed actions;
• if reducing the sensitivity of the alarm is possible by adjusting the shock sensor itself using screws or buttons, then by selecting the level of the car alarm, it is necessary to set its desired value;
• in case of negative results of alarm adjustment, incl.

It is best to hit the wheel - this way you can avoid damaging the car's surface. This way you can determine the optimal level of sensitivity so that the alarm does not bother you over trifles.

Why do you need to reduce

Could the alarm be too sensitive?
The question is not at all rhetorical. Its relevance has been felt by many owners of car alarms. It’s not at all difficult to understand when an alarm goes off properly and in a timely manner, and when, in addition to the hassle of idle ringing, it ruins the life of its owner. Still, it’s not a joke: 100 dB of a car’s security siren regularly howls in the middle of the night against the permitted 30 dB. If we also mention the loud keychain, which forces its owner to jump out into the street for no reason in order to save his car property, then it will become clear how harmless this very notorious sensitivity of the Starlien car alarm is. Although the reasons for the need to reduce it are quite simple and can be easily eliminated even on our own:

• The adjustment of the shock sensor, when installing it, is made taking into account the maximum sensitivity of the alarm system, incl. and Starline;
• reducing the “sensitivity” of car alarms, incl. and Starline, is associated with a violation of the sensor’s attachment to the car body;
• both reasons simultaneously influence the decrease in the “sensitivity” of the alarm;
• warranty or emergency case of poor car alarm operation.

Important: the main difficulty when setting it up for any alarm will be finding a shock sensor. Its approximate location is known - under the trim next to the clutch pedal. But you still have to look.

How to disable

Disabling the shock sensor is used to reduce the number of false alarms caused by external factors. At the moment of remote or automatic start of the power unit, the security complex turns off the sensor, since vibration from a running engine is perceived by the sensor as an attempt to penetrate the vehicle interior. When setting the operating parameters of additional channels, it is possible to set a parameter that temporarily disables the shock sensitivity sensor.

To disable the shock sensor on Starline A91 or A93, you will need to press the remote control button, indicated by the closed lock icon, twice. The car will respond with a double signal from the external light alarm, the key fob will give a melodic signal, and the text DAT1 will be displayed on the display, indicating a temporary disabling of the warning sensitivity level. When you press the button twice again, triple signals are sent by lamps and a buzzer, and then the alarm level is turned off. A text like DATE2 appears on the display.

The car owner can turn off the sensor by turning the sensitivity control to the minimum position. On the A93 complex, you need to set the zero value through the setup menu. It is not recommended to disconnect the shock sensor on the Starline A91 by disconnecting the cable harness from the processor unit.

Basic alarm faults

Most often, motorists have to deal with malfunctions that arise during the operation of the Starline A 91 car alarm:

1. When you press the key fob control buttons, the alarm does not go off (you need to replace the battery, replace the key fob).
2. A false alarm occurs (the settings of the alarm sensitivity unit need to be calibrated).
3. When you turn on the car door locking mode, a malfunction occurs (the reason may be a malfunction in the alarm system or the locking mechanism).
