1. An alarm system for circuit protective devices utilizing the existing electrical wiring;
- comprisinga plurality of wall mounted electrical receptacles connected to the existing electrical wiring;
at least one sensing means directly affixed to each of said receptacles for sensing the presence of a fire condition in the environment in proximity to said receptacles, said sensing means providing a signal when the presence of a fire condition has been detected;
a plurality of first conversion means connected between said sensing means and said electrical wiring for converting the signal produced by said sensing means to an encoded RF signal and conducting said signal over said existing electrical wiring, each of said first conversion means connected to one of said sensing means and each of said first conversion means provided with an encoder for producing an encoded signal different than the signal produced by at least one other first conversion means;
a panel box provided with a plurality of circuit protective devices therein, said panel box connected to said electrical wiring downstream from each of said first conversion means;
alarm means associated with said panel box for aurally or visually indicating the presence of a fire condition in the environment in proximity to one of said enclosures; and
second conversion means connected between each of said first conversion means and said alarm means for converting the respective encoded RF signal produced by each of said first conversion means and transmitted over the existing wiring to said second conversion means to an electrical or electronic signal, said electrical or electronic signal produced by said second conversion means activating said alarm means.

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.
