Anti-theft device – specifications: (ALARM)

The alarm system carries out:

• perimeter surveillance
• volumetric surveillance
• surveillance against tilting of the car (with tilt sensor)
• surveillance of cutting the supply cables
• surveillance on the ignition key block.

The system is coordinated by the BC which sends/receives commands from the external modules via the serial line:

The system is switched on/off via the remote control interfaced with a received located in the BCN; the remote control and receiver are at radio frequency.

The alarm system is also switched off by inserting an enabled key recognised by the ALFA CODE (emergency switching off).

When it is switched on, the doors are locked.

When the system is switched on, volumetric protection can be excluded.

After an attempted break-in, a blinking code emitted by the dissuasion warning light indicates which sensor has detected it: this warning light also indicates the state of charge of the transmitter's battery.
