Auxiliary equipment, white/red lead
This alarm loop protects integrated auxiliary equipment in the car such as radio/cassette players or similar equipment. The circuit is normally closed (NC) and triggers the alarm when interrupted.

Door trigger 1, grey lead This input is normally open (NO) triggers the alarm when a contact to ground is made. Connect to the existing door switch circuit of the car. If the car has two separate circuits from the front and rear interior illumination, door trigger 2 (P-4.12) can be used for the rear doors, and input P-4.5 can be used for the front doors.

Bonnet trigger, black/grey lead This input is normally open (NO) and triggers the alarm when connected to ground, i.e. when the bonnet is opened. Install DEFA Bonnet Switch. This should be installed in such a position as to make it inaccessible from either the underside or the front of the car.

Door trigger 2, grey/white lead This input is normally open (NO), and triggers the alarm when contacted to ground This is an additional door switch input for NEGATIVE switches and is used particularly when there are separate circuits for the front and rear doors.

Microwave Sensor
The preferred location is at the centre of the car roof, 40 cm from the windscreen, under the roof lining. If this is not possible, it can be installed in the centre console. The sensor can be installed behind plastic covers but not behind metal covers, as these would block the waves from the sensor. Please note that some cars have a thin metal film in the roof lining. In these cases, the sensor must not be installed behind this lining.

If the sensor is attached to the inside of the roof, the arrow with the mark UP is usually located on the underside of the sensor and points towards the rear of the car interior. If the sensor is attached to the centre console, the arrow with the mark UP is usually located on the side of the sensor facing the interior. The sensitivity of the sensor must be checked and, if necessary, adjusted after installation.
