VOLUMETRIC ULTRASONIC SENSOR (Ref. B)

The transducers can be installed on the windscreen or rear window pillars. The best

place is just above the surface of the dashboard.

Wherever they are installed, make sure that the transducers do not interfere with any

other parts.

It is of fundamental importance to correctly position the transducers so that they are

able to offer a full degree of volumetric protection: direct the transducers towards the

rear window so that they approximately converge towards the center of it. Fix them

with the supplied screws. Make sure that the transducers are not obstructed by any

other object (plugs, covers, upholstery).

Remember to fix the relative microphone in a central position of the vehicle. The best

place is on the dashboard, pointing towards the rear window. This position achieves

uniform sensitivity.

BONNET BUTTONBONNET BUTTON

BONNET BUTTON

Use the material supplied in the kit. After it has been installed, make sure that the

button is pressed by the bonnet to the extent of at least 5 mm. Make sure that the

button is unable to press against the soundproofing panels or on the external bodywork

since these materials could become deformed in time.

Cover the button with a film of grease to protect it from rust.

ANTENNAANTENNA

ANTENNA

The antenna is of fundamental importance for operation of the radio control system.

Comply with the following instructions:

The wire must not be cut, wound, connected to other wires or to the bodywork.

Keep the antenna at least 20 mm far from the car body and other metallic parts.

ELECTRICAL CONNECTIONSELECTRICAL CONNECTIONS

ELECTRICAL CONNECTIONS

We raccomand you to pay attention while joining together two or more wires. It is

inadvisable to make “quick junctions” that fail to ensure good quality connections.

Remember to position the alarm wires so that they are routed along with the original

harness of the vehicle and to attach them to this with the relative clamps.

Refer to the enclosed wiring diagrams when making the electrical connections, bearing

the following instructions in mind.

• the ground must be shunted from an original ground point of the vehicle or connected

straight to the negative pole of the battery.

• the positive wires of the alarm unit must be connected to a positive of the fuse box

(with the voltage drop sensor activated the alarm unit power supply must be connected

to the entry light wire feed).

• the engine immobiliser function must be obtained by interrupting the fuel pump relay

or pump control circuits. It is essential to block the fuel pump in vehicles with catalytic

silencers. The internal relay and the engine immobiliser wires withstand the maximum

current rating indicated in the wiring diagrams. Before connecting the GREEN wires,

remember to measure the current in the point selected for the connection.

The interrupted wire can be either positive or negative

The voltage drop sensor is also built-in and it is able to detect at least a 5W interior

lamp which is switched on. When this sensor is activated the power supply red wire

must be connected after the interior lamps fuse.
