Abstract

The electric alarm system is key-sensitive, having alarm and lock-control circuits including a motor, a relay, and an alarm. Cams may form individually insulated contacts, one being permanently live and one other being coupled to a control circuit. The correct key may be a metal electrical conductor with an insulated finger grip and closes the control circuit which includes the motor to release the bolt via a spring with a rack formation engaged by a motor driven pinion. An incorrect key may close the relay circuit to eventually close a parallel alarm circuit. The relay is electromagnetic and automatically breaks the control circuit when making the alarm circuit.
