ALARMS

The alarm system offers volumetric and perimeer protection for the vehicle.

In effect, an electronic control unit checks:

the closure state of the doors and lids (perimeter control)

the presence of a moving object inside the passenger compartment (volumetric control)

the operation of the ignition switch

the condition of the supply cables for the vehicle and the emergency key.

NOTE:

The radiofrequency type of remote control adopted facilitates the activation operations because this system has a high capacity, which is non directional and not affected by the transparency and cleanliness of the windows.

In addition, the system for transmitting the secret code between the remote control and the receiver is a rolling code, in other words a cipher code which is different each time.
