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.
