Abstract

A security circuit and alarm triggering network for application to door locks either in buildings or in vehicles, activates a horn or alarm when the door is opened without the key. The basic circuit consists of a parallel arrangement of contacts (31, 32, 37) and relay contacts (21a) which operate so that when the door is locked, a relay (21) circuit is formed so that if an unauthorised entry is made, the relay switches on and holds, another relay (22) is actuated, and an alarm or horn (38) is actuated through the contact of this second relay. The circuit is powered by a battery. A slightly different alternative circuit is also described.
