Functional Description
Overview – Alarm
The Vehicle Alarm System (VAS) will generate an audible
and visual warning if the vehicle doors, bonnet or boot are
opened without first disarming the system using an
authorised remote transmitter key.
There are two types of alarm system:
• Standard
• High Specification (optional). Includes an interior
movement sensor and tilt sensor
The interior movement sensor offers further protection of
the ignition barrel and steering wheel lock, the tilt sensor will
detect unauthorised angular movement of the vehicle.
A Battery Backup sounder (BBS) is used to protect the
sounder from disconnection. The BBS will sound if any
attempt is made to disconnect it from the rest of the alarm
system when the vehicle is armed.

transmitter 'Lock' button. The alarm system will arm and
deadlock 25 seconds after receiving the arm request.
Door open
If the alarm system is set when any door, bonnet or boot are
left open, then the alarm will be armed on all closed doors
only, 25 seconds after the alarm set command has been
requested. The open door, bonnet or boot will not be
armed. 5 seconds after the open door, bonnet or boot have
been closed, the alarm will Arm on that door, bonnet or
boot.
