There are different terms for a designation of this group of the goods - car alarms, automobile alarms, security systems, anti-theft systems”. The Most strict and official name is “the system of the anticreeper signalling”, (”Union of Right Forces”). The most widespread name - “autosignallings”.

There is a concept of an anticreeper complex, as a rule, it is the car alarm plus mechanical protection frames (various blockers).

Autosignallings are the electronic devices which are carrying out certain security and service functions (for example, distance control by locks of doors, an autostarting engine operation, car search, a support of ignition and other).

These devices are included into the general group of the goods of electronic tuning of cars where refer to also diverse automusic, a tele-and video equipment for cars, antiradars, parking sensing transducers, on-board computers, the illumination, some devices.

The car alarm complete set usually consists of the basic steering block (with the processor and the software), charms for distance control, wires, sensing transducers (usually only a shock-sensor control), assembly details. Sometimes as a unit there is a siren.

There is a number of accessories for car alarms - electric drives for locks of doors (”machine”, “door lock actuators”), sensing transducers (blow, volume, traffic, an inclination), additional relays and the interlock relay, limit switches and carriers.

All cars are issued already with a number of solutions on security and service functions. However different brands are equipped rather differently, especially a few such functions in the standard complete equipment of domestic cars. It cannot be connected with inability of car factories to put on cars any options. To automobile owners different options are necessary, to someone, was possiblly, will be simple factory base complete equipment enough, and exclusive tuning is necessary to someone.

The word “tuning” (English tuning - adjustment, resetting) as a result of wide application in the world, has got sense: any finishing. For example, the car is issued in the base complete equipment, with weight of factory options (i.e. can be, can not be, sampling for the customer of the car). Here (from other producers), it is possible to name any other additional changes, other equipment tuning.

All it to the full refers to and to car alarms.

It is possible to tell, auto alarm installation, in comparison with other aspects of tuning, is enough necessary, standard installation of the additional equipment, new motor vehicles without autosignallings in maintenance do not appear. It is connected and with raised in modern world, and the appreciated users the service possibilities given by the majority of security automobile systems.

As a rule, motor shows sell motor vehicles at once with the installed signallings, with other finishings and the equipment. Is more often it becomes at will of the buyer, but sometimes these additional services are frankly imposed.

Some small motor shows, struggling for buyers, save on everything, select the most low-cost additional equipment, instal it is inadmissible sweepingly and poor. Large motor shows, value the reputation and provide an entrance and target quality control additional equipment, observe production engineering of its installation.

Certain standard demands are made to car alarms. Except the general compliance with requirements to the electronic goods, the allowed radio frequencies and power of a charm are necessary full compatibility with the motor vehicles.

Installation of auto alarm should be made by specialists, it is better - in the certificated technical centres giving an assurance on installation and the signalling.
