Preparations for installation Further information, see technical manual.
The workshop always holds complete responsibility for performing all necessary safety measures on
installation of the alarm system. Observe any instructions issued by the car manufacturer. Before making
any connections, use a voltmeter/multimeter to check the connection points. Always ensure that the
connection points are well insulated by using, for example, shrinkdown plastic tubing or insulation tape.
Avoid installing connection points or installation components in the immediate vicinity of airbag
modules or other safety systems.
The alarm can act on all petrol and diesel cars having a 12V power source.
Important: DEFA alarm modules, series 820 (without DEFA Immobilizer), may only be installed
in vehicles with approved original Immobilizers; if this is not the case, the Alarm will not be
subject to type approval. A list of recognised original start lock systems is available from DEFA
or the DEFA representative in your country.
Positioning of the Alarm units
Central Unit
Attach the Central Unit below the instrument panel or at a suitable point in the vehicle interior using
plastic fastening strips. The Central Unit should not be visible, and should be as inaccessible as possible.
Important: The Central Unit must be installed with its plugs facing downwards to ensure that
condensation water cannot run along the cables into the unit.
Main fuse
The main fuse (25 amp.) should be attached in the vicinity of the current power source.
Siren
Install in the engine compartment, exposed as little as possible to spray water and heat from exhaust or
turbocharger components (minimum distance 30 cm). The Siren aperture must face downwards to
prevent water accumulating in it. Important: Never install the Siren with the aperture facing upwards.
The Siren must not be accessible from the underside of the car.
Important: Never install the Siren with the aperture facing upwards.
Glassbreake Sensor
The Glassbreake Microphone is installed on the instrument panel or in the centre console. Clean the
installation surface with a grease dissolving agent and then fasten the Glassbreake Sensor with the
enclosed double-sided adhesive tape.
LED
Install in instrument panel using the embedded bracket or fasten to the instrument panel/windscreen
using a universal bracket or double-sided adhesive tape. The LED must be clearly visible from outside.
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.
