Abstract
A fire detecting system utilizing existing electrical wiring in conjunction with circuit protecting devices provided in a main panel box. Various sensors which sense the presence of a fire condition are directly affixed to plug receptacles or wall switches. These sensors activate a short circuit device or a controlled overload which is utilized to trip a circuit breaker and activate various visual or aural alarms. An alternative embodiment employs an encoded RF signal transmitted over the existing wiring, tripping the circuit breaker by an electromechanical device, thereby activating the aural and visual alarms.
