Abstract

The automatic anti theft device for a vehicle gives a alarm and discourages theft. It is applicable to any vehicle with a battery and coil ignition and depends on detecting current variation from the battery when a door is opened etc. The relay has contacts, one normally closed and in series with the ignition coil and the other normally open and in parallel with a contact of the horn. The relay is controlled by a timer, adjustable by a potentiometer. The input to the tuner is controlled by a bistable controlled by a transformer secondary, the primary being in the battery positive lead. The device is immobilised by a hidden button.
