Alarm control unit

The radiofrequency alarm system offers both volumetric and perimeter type protection; in effect, it checks the state of the lids/doors and for the presence of a moving object inside the passenger compartment. In particular, it is capable of:

• adapting its operation to suit the regulations governing alarm systems in force is various countries;
• memorizing the number of times the alarm system has been activated;
• detecting faults and irregularities in the system connecting cables.

The alarm system comprises:

• a radiofrequency receiver, located in the luggage compartment;
• a radiofrequency remote control, integrated in the key;
• volumetric control sensors, incorporated in the courtesy light;
• front/rear door and lid sensors;
• an alarm control unit, located in the engine compartment opposite the battery, which includes a self--supplied siren (see diagram below);
• an emergency switch with a key (ON-OFF), on one side of the actual control unit (see diagram on page 4).

NOTE The radiofrequency remote control facilitates the operations of activating and programming because, compared with infra red systems, this system has a greater operating radius, is not directional and is not affected by the possible poor transparency of the windows.

ALARM CONTROL UNIT

The alarm control unit is the main unit of the system. It checks and processes the signals coming from the:

• rear boot sensor;
• front bonnet sensor;
• door opening closing/sensors, in the locks;
• volumetric sensors;
• ignition switch.

ALARM SIREN

This is a compact type self-supplied siren, integrated in the control unit.
The intensity of the siren sound depends on the country where the vehicle is registered (see "COUNTRY CODE PROGRAMMING").

NOTE The siren can be excluded by pressing the remote control button for more than 4 seconds when the alarm is switched on.

RECEIVER

The receiver, located in the luggage compartment as illustrated in the diagrams overleaf, is an electronic device which receives the signal coming from the remote control. It carries out the tasks of opening/-closing the doors and activating the alarm control unit.

Each receiver can be programmed with one or more remote controls (however, only the last 8 are retained) memorizing the codes.

There is a green LED (3) on the receiver (see diagram overleaf) which comes on when the signal is received, whilst a special button (2) allows the code to be memorized.
