Operation

.The electronic control unit also comprises the compact siren : it is to be found at the rear in the luggage compartment.

The siren operates at different intensity depending on the programming for the different countries (see description below).

The emergency key for deactivating the system is located on the actual control unit, thus access to it is quick and easy.

1. Electronic control unit
2. Siren
3. Emergency key

For the control of the doors and luggage compartment the same switches as for the door locking system are used (see sections "Door locking system" and "Luggage compartment opening control"): all the switches signal when the doors are "not closed" (door open = earth signal to the control unit).

There is a special switch on the bonnet which operates with the opposite logic: (bonnet closed = earth signal).

The two volumetric sensors enable extra surveillance controlling that there are no intrusions inside the car. They are incorporated in the front ceiling light; one acts as a transmitter and the other as receiver; the beam of ultrasounds emitted by the former (left) must be wholly picked up by the latter (right), after a number of "rebounds" inside the passenger compartment: if not, an alarm signal is sent to the control unit.

The system signalling led (red, of the high efficiency type), is located on the dashboard, on the upper half cover of the steering column behind the steering wheel, and it signals the state of the system and any faults (see following description).

OPERATION

ENABLING/DISABLING

It is only possible to enable the alarm when the ignition key is in the STOP position.

ENABLING is possible by pressing the button on the transmitter.

DISABLING is obtained by pressing the same button once again.

To obtain the most efficient switching, press the button until a visual and acoustic signal are noted (feedback).

N.B. The system is protected against unauthorised recording of the secret code.

Enabling

Press the button whilst pointing the transmitter towards the receiver dome. Acoustic and optical signals will be noted (for the markets/versions foreseen).

Disabling

Press the button pointing the transmitter towards the receiver dome.

Also for disabling acoustic and optical signals will be noted (for the markets/versions foreseen).

COMPLETE DEACTIVATION OF THE SYSTEM

If the batteries of the transmitter are flat or the system is not working properly, the alarm system can be deactivated using the emergency key on the control unit.

When the car is delivered this emergency key must be in the "ON" position.

Turning the key to "OFF" the system is deactivated completely. In the specific version for some markets, only the batteries inside the control unit/siren are deactivated, leaving the alarm system activated as it is still supplied by the car battery.

With the key at "OFF" the surveillance of the cable cutting/battery disconnection is no longer activated.

Set this key to "OFF" and disconnect the battery cable if the vehicle is left unused for long periods (over 1 month).

"SURVEILLANCE" MODE

During the "surveillance" mode (car closed and alarm activated) the dissuasion led flashes at 0.8 Hz, in this conditions, the system;

• checks the doors, bonnet and tailgate;
• checks that the battery is connected and that the leads are intact;
