ALARM - Description

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.

For more details.

All external components are connected to the Body Computer via a dedicated serial line.

The alarm siren is located at the front, under a Locary on the left of the engine compartment.

The door lock system switches are used to check doors, boot and bonnet.

A special switch detects bonnet closure.

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.

Pressing the special button next to the sensors makes it possible to switch the function on/off: with the sensors excluded an LED next to the actual button comes on.

The deterrent LED is located at the side of the driver's door safety knob: it signals the 'central locking' functions. See E3040 CENTRAL LOCKING

With the alarm on the LED flashes at 0.8 Hz to indicate that the vehicle is immobilized (deterrent function).

The deterrent function is also implemented if one or more of the doors or the boot is not properly closed.

The remote control receiver aerial is connected directly to the Body Computer which contains the electronics for the actual receiver.

Passive entry

Description

The RF aerial-receiver sends the Passive Entry control unit a door opening/closing signal in the same way as a conventional remote control. for more details See E7018 PASSIVE ENTRY.

All external components are connected to the Body Computer via a dedicated serial line.

The alarm siren is located at the front, under a Locary on the left of the engine compartment.

The same switches as for the central locking system are used to control the doors and lids.

A special switch detects bonnet closure.
