3023579 - E7015 ALARM - Description (3 porte)
Description
The intruder alarm system offers volumetric
and perimeter protection.A control unit (inside the Body Computer)
controls:
- status of doors, boot and bonnet via switches in the locks
(perimeter control);
- the presence of a moving object inside the passenger compartment,
via volumetric sensors. (volumetric control)
- the condition of system supply leads;
- operation of the ignition switch.
The control unit is equipped with an autodiagnostic
function which detects and memorizes faults in the control unit
itself and the system components; it also checks the condition of
link cables and stores the number of activations and the number
of alarms. The control unit operating software may
be altered to meet regulations governing the use of alarm systems
applicable in different markets.

The alarm siren is located at the front,
under a Locary on the left of the engine compartment.The remote control system consists of a
sending unit built into the key and a receiver built into the Body
Computer.The same switches as for the central locking
system are used to control the doors and lids. A special switch
detects bonnet closure. (A buzzer goes off if the body computer
detects that one of the doors or the boot is open and the car is
travelling faster than 3 km/h).The volumetric sensors check for car intruders.
They are located in the two centre pillars. Both are twin sensors,
i.e. consisting of an emitter and a receiver: the wave transmitted
by an emitter should reach the receiver of the other sensor and
viceversa: if this is not the case, an alarm signal is sent to the
control unit.The deterrent LED is located on the central
control panel and indicates the state of the system (on, off, etc.
) plus any faults.All external components are connected to
the Body Computer via a dedicated serial line.
