Abstract

The vehicle anti-theft system consists of an inverter (10) to transform the battery (2) potential from 12 volts to approx. 400 volts. The high output is fed to a switch unit (11). The switch unit is connected to the ignition coil (5) and a control unit (12) (contact breaker). A further part of the anti-theft system consists of a first alarm (13). The first alarm has a 10 second time switch (14). The second alarm gives longer alarm signals of 5 minutes duration. The time switch is actuated by a relay (J1) connected to a door switch (8) and the horn (6). The circuit is energised by a connection plug (9) and a coded key. The plug has a condenser which on discharge automatically activates the door switch alarm after 10 seconds. The coded key contains an indispensable electronic component vital to the ignition circuit.
