Basic car alarm functions

Despite the large variety of security systems for cars, each of them performs a number of important functions that protect the vehicle from theft. Each individual model has more or fewer options that prevent theft and make the use of car alarms easier and more convenient.

The importance of functionality in car alarms

The main functions that can be in car alarms are completely different; they have their own characteristics and advantages of use. In addition, every year the manufacturers of anti-theft systems invent something new, providing more comfort and ease to the driver during the operation of these devices.

Choosing a car alarm for installation it is important to familiarize yourself with its functionality in order to avoid unpleasant situations during its operation, as well as eliminate the possibility of vehicle theft. For more detailed acquaintance – functions, and features of their work and use.

Jack mode

This function consists in briefly disabling the guard function (with the exception of the «Panic» mode). It should be use in the case of, for example, contacting an auto repair station, where the driver wants to leave his car for diagnostics or repair. In this case, a hidden button or switch is used – then your car remains completely unguarded.

Very often, manufacturers set this mode separately from the mode settings; it used separately to enable short-term disabling of the guard functions. Some functions of this mode can be configure by entering an additional mode in order to program the options.

Anti-theft system programming

This mode can use to change the system service settings that have been set by the manufacturer. It implies a change:

«polite backlight»;
installation or dismantling of electric locks;
siren sounds by turning them off or adjusting the volume.

These and other functions can be change using the programming mode. For this, many devices have a special button. Very often, this switch performs the functions of two modes – programming and «jack».

Key fob activation

This mode is necessary to activate the new key fob in case of losing the old one. When replacing the battery on the main key fob, you must also use this mode. In each of these situations, it is necessary to use this option to confirm the correctness and succession of actions.

Panic Mode

It divided into 2 types – Anti-Car Jacking and Anti-Hi-Jack. In the case of theft or theft, with the presence of a driver near the car, the owner can simply press the necessary button on the key fob. Then the car, having driven a certain distance, begins to be gradually block by the system:

the siren is activated;
side lights start working;
the engine is blocked.

This is how Anti-Car Jacking works. Another mode of operation of the «Panic» function implies activating it during door opening, turning the key in the ignition lock. This option used if the machine is located at a sufficiently large distance from the key fob of the owner, and it cannot reach the car alarm receiver. This is how Anti-Hi-Jack mode works.

«Polite lights»

This option turned on when the driver turns off the ignition – inside the car turns on the interior lighting to more conveniently pull out the keys from the ignition, collect their belongings and exit the car. This function is very convenient, there is no need to turn on the salon lighting, look where the button to turn it on. After exiting the car and closing the doors, you need to press the button of the key fob and for some more time, about 30 seconds, the light will light your way.

The inclusion of a «polite backlight» also works when approaching the car. During the removal of the alarm, this function immediately activated, it will help you open the door faster, arrange your belongings and turn on the ignition lock.

Some anti-theft systems are equipped with a smooth on and off «polite backlight». This option considered optional; it provides more comfort during use of the alarm for cars.

Programmed security disable code

It used in the absence of a key fob or if the battery is discharged in it. When you open the car, the security system immediately activated; the driver can use the ignition switch and emergency shutdown – «jack» mode. Then you need to enter the code specified by the owner earlier when setting the alarm for the car. The algorithm of action may be as follows:

1. on/off ignition;

2. pressing the emergency shutdown 1 time;

3. re-on/off the ignition;

4. press the emergency shutdown 2 times.

It is worth noting that this is one of the intended options for activating this code, it may differ in each security system, and this information indicated in the instructions for the device.

AntiScan function

This option is necessary to exclude the likelihood of selecting a code for car alarms by the usual selection of numbers. The work of the Anti-scanner consists in turning off the alarm receiver for a certain time, and then the device does not respond to any actions and inputs. Such behavior of the security system is possible in case of entering the wrong code several times, in particular 2 or 3. Thus, such an intermediate selection will take a very long time to break the code.

Antigrabber option

This option designed to exclude the possibility of disabling car alarms, even in the case of reading the code from the key fob. In this case, it is necessary to use a dynamic code. It must be enter after the programmed code, and only then, this feature will be disable.

Electric lock

This mode provides for the automatic closing of all doors of the car after leaving it, during arming. Upon arrival to the car, the guard also removed by pressing the button and the entire door locks opened.

The use of this function is possible due to the presence of the controller in the system; it is equipped with a power or non-power output.

Power outputs provide the ability directly connect the electric locks to the anti-theft control unit.
Non-power outputs imply installation of additional equipment for communication, for example, a relay.

The design of the electric locks of different vehicles is different, therefore, to lock or unlock those takes some time. Many anti-theft systems equipped with a controller are equipped with a function to change the pulse duration. Moreover, in order to activate the locks, the user need only select the desired option.

Power window controller

This option can also be equipped with a security system. It activated when the car is armed: if one or several glasses lowered, then when the system turned on they will automatically rise. Its principle of operation is similar to electric lock controllers – there are power and non-power outputs, they can be connected to the control unit or using a relay.

Warning of attempted theft

This function is triggered in the event of an attempt to hijack a car or when entering a car. In this situation, the alarm activated. Later, when the driver comes to the car, removes it from the guard; he can see that there was an attempted theft:

1. siren signals will be different than usual;

2. By LED indication, the driver finds out that someone tried to steal his car.

Therefore, the driver will notified of the attempted theft and will draw the necessary conclusions.

Bypass the faulty area

This function means turning off those zones where the faulty elements of the system are located. Therefore, in the event of a malfunction of one of the sensors, the driver, during the activation of the alarm, will notify of this by flashing the parking lights and the indicator, as well as by an alarm siren. If he is not trying to do something, then the system will automatically turn off this zone, while not only one faulty sensor, but also all that connected to one input.

Thus, many car alarm manufacturers equip several additional connectors to enable each sensor connected separately. Therefore, the weakening of the security function will be minimal.

Auto Arming

After leaving the car, the system automatically turns on the anti-theft system 30 seconds after the doors are closed. At the same time, it works, unless the driver has opened the trunk or rear door, the hood of the car. This option has several advantages:

1. no need to press the key fob button;

2. the possibility of breaking is excluded, since the hijacker will not be able to read the code that is transmitted when using the key fob.

The negative side of using this function is the probability of locking the car, while the keys and key fob from the car will be in the cabin. In addition, this feature is often annoying drivers, and they do not use it. An important caveat is that it is undesirable to combine the function of outputting to the electric locks and auto-arming, therefore it recommended disable the first option in this situation.

Settings Memory

This option used if the battery is low or the driver needs to disable the on-board network. In this case, you can use additional power to save the system settings. This function will be necessary for those who have many options do not match the factory.

Engine blocking

Blocking the engine makes it difficult for the engine to start when armed. Functioning of the «Panic» option. The operation of this option causes the car to stop and it is impossible to move further.

To connect this function, most often, it is necessary additionally purchase actuating equipment – a relay or a gas valve, which are responsible for blocking the engine. Sometimes this option makes immobilizer, distinguish the integrated version – is built into the control unit, or a separate one. If there is no actuator, if the Panic mode turned on, the car will still move.
