DESCRIPTION AND OPERATION

ANTI-THEFT ALARM DESCRIPTION (96 MODELS)

NOTE: The alarm system provides security
protection under wide ranging
circumstances and is fully programmable

to meet market requirements; consequently some
of the features listed will vary dependent on
vehicle model or territory.

The handset is intended to be the primary source of
control for the alarm system. The key should only be
used in the event of handset failure or if perimetric
arming only is required.

Immobilisation

After a time period the vehicle is automatically
immobilised regardless of whether or not the alarm is
armed.

Mobilisation

The handset provides the normal means of
mobilisation. In the event of handset failure, the key
may be used to enter the emergency key access
code.

Perimetric arming

Provides protection whilst the vehicle is still occupied.

Volumetric arming

If movement within the vehicle is detected the alarm
will be triggered.

NOTE: Perimetric arming always
accompanies volumetric arming.

Built-in test

The alarm system has a built-in test procedure, but if
possible any fault finding should normally be
undertaken using TestBook.

Emergency key access (EKA)

In the event of handset failure the alarm can be
disarmed by entry of the EKA code which is unique to
each vehicle.

CONTROL SYSTEM

Electronic control unit (ECU) and relays

The ECU is the alarm system ’brain’ and controls all
alarm functions. It responds to inputs received, by
supplying suitable outputs to indicate the status of the
alarm system or activating the relevant warning
devices.

Handset

The handset is the primary source of control for the
alarm system i.e. it locks and unlocks the vehicle,
arms and disarms the alarm.

Door key

The vehicle may be locked using the key (perimetric
arming only).

NOTE: The vehicle MUST be unlocked
using the handset. The key may be used to
unlock the vehicle if the handset fails to

operate, see operation, Emergency key access.

Passive coil

The passive coil is located around the starter switch
and triggers the handset (usually located on the
keyring) if it is within close proximity.

Aerial

The aerial is a floating connection which supplies the
alarm ECU with the signal received from the handset.

Immobilisation unit (spider)

Dependent on model or territory, the system may be
fitted with an immobilisation unit which is discreetly
located and provides an interface between the ECU
and immobilised areas of the vehicle.
