Anti-Theft Alarm 900 with VSS


The anti-theft system for the Saab 900 consists of an alarm and a security system controlled by a remote control unit. Two versions of the alarm are available:



1. Anti-theft alarm, which is practically identical to the earlier M95 Anti-Theft Alarm 900.

2. Anti-theft alarm with VSS (Vehicle Security System), which is a further development of earlier alarm designs and constitutes a more complete anti-theft alarm system.

Although most of the functions are identical in both alarm versions, there are some important differences.



The anti-theft alarm is available:



• factory-fitted

• as an accessory kit (all cars are pre-wired). The anti-theft alarm with VSS is not available as an accessory kit.

The alarm includes a number of components, some of which are used exclusively by the alarm, and others of which are parts normally included in the car, but also used by the alarm.

Some of these, such as sensors, have a monitoring function in the system and others set off the alarm. There is an electronic control module that centrally controls the operation of the system.

The anti-theft alarm is programmable so that it can be adapted to meet the requirements and laws of different countries, as well as the preferences of different customers.
