Fire detection alarm system
First Claim
1. An alarm system utilizing the existing electrical wiring provided in the structure and wall mounted electrical receptacles and wall-mounted switchplates connected to said wiring, each of said wall-mounted electrical receptacles and switchplates provided in a protective area, comprising:
- at least one alarm signal generating means connected to said receptacles or switchplates for producing an alarm signal;
a plurality of first conversion means connected between said alarm signal generating means and said electrical wiring for converting the signal produced by said alarm signal generating means to an encoded RF signal and conducting said signal over said existing electrical wiring, 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;
second conversion means connected to each of said first conversion means by said electrical wiring 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;
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; and
a central monitor provided at a location remote from said panel box for displaying the location of each of said alarm signal generating means, said central monitor visually displaying the location of each of said produced alarm signal based upon the signals generated by said conversion means.

Abstract
An alarm system utilizing existing electrical wiring in conjunction with an alarm box. An alarm signal is manually or automatically generated and is converted to an RF signal which is conducted over the existing electrical wiring to an alarm box. The RF signal is re-converted to an electronic or electrical signal and the alarm signal is visually displayed. Various sensors for sensing the presence of various conditions, such as fire or unauthorized intrusion are removeably or directly affixed to plug receptacles or wall switches. Additionally, the system is connected to circuit protection devices, such as circuit breakers which could be tripped, should a fire conduction be sensed.
