III - OPERATION

A - PERIMETRIC PROTECTION
The information about the status of the doors, bonnet and boot is acquired by
the interior lamp control: if, after a time, the interior lamp or lamps are
extinguished, the vehicle is considered to be closed.
If the bulbs in the interior lamps are missing or faulty, the alarm is not affected:
the information is taken from the command sent by the BSI.
If a door remains open after the alarm is armed, the siren sounds for 30
seconds, up to 10 consecutive times. It is no longer triggered after this.
B - VOLUMETRIC PROTECTION
Volumetric protection is active 45 seconds after the alarm is armed.
If movements are detected before the end of this timer, volumetric activation is
delayed, several times if necessary.
Volumetric protection can be prohibited in the same way as for the factory
fitted alarm.
Note: Tests on the volumetric protection must be performed with the doors
and windows closed.
C - DISPLAY
An LED for this purpose is incorporated into the dashboard.
The LED operates in the same way for both vehicles:
