The system includes a central contactor unit which comprises a central arming point for the vehicle alarm. Once armed the system actuates (1) solenoid valves to shut off the fuel supply conduit and the air supply conduit to the engine (2) solenoid locks for the bonnet and boot, and the system prevents engine start-up by interrupting the current to the starter motor. A tilt switch is also armed which triggers an alarm under the vehicle bonnet and boot if removal of the wheels is attempted. Switches for the vehicle doors, bonnet, boot and electronic equipment within the vehicle (e.g. radio, cassette player) are provided which trigger the alarm on unauthorized entry/interference. The system is armed by removal of an internally wired plastic strip. For 8 diesel engined vehicle a relay/solenoid is provided for preventing fuel preheater operation.
