Description

The alarm system offers volume-sensing and perimeter protection against intrusion into the vehicle.A dedicated control unit monitors the following:

the state of the doors and lids, via switches in the catches (perimeter control)
the presence of a moving object inside the passenger compartment, by means of volume-sensing sensor (volumetric control)
the condition of the system supply leads;
operation of the ignition switch.

The control unit is equipped with a self-diagnostic function which detects and memorises faults and problems in the control unit and system components; in addition, it checks the condition of the connecting cables and saves the number of activations and times the alarm has been operated.The control unit operating strategy can be modified in order to satisfy the legal requirements which govern the use of alarm systems in the various markets.The door lock system switches are used to monitor the doors and boot.A special separate switch detects bonnet closure.The volumetric sensors check for intrusions into the vehicle. They are located in the front courtesy light: they consist of a transmitter and a receiver: the wave transmitted by one transmitter must reach the receiver of the other sensor and viceversa: otherwise an alarm signal is sent to the control unit.The function may be activated/deactivated by pressing a key next to the sensors: when the sensors are excluded, a led next to the button is turned onSystem activation is displayed by means of a special deterrent led.
