Internal locking

Perimetric alarm
The perimetric alarm is used by the BCU to detect unauthorised opening of a door or hinged panel. Switches 
incorporated into the door latch assemblies and the bonnet determine the state of the panels.

driver's door. Once the alarm has been set, the BCU monitors the state of the doors and the bonnet.

In order to arm the perimetric alarm the following conditions must be met:

l

Drivers door closed.

l
