ABSTRACT:
A solid state reset circuit responds to the actuation of a single manual device to both transmit reset signals to the input circuitry associated with fire and intrusion sensors of a security system, and to transmit an arm/disarm signal to the intrusion sensor circuitry if an intrusion alarm condition is present and a fire alarm condition is not present. The use of a single manual device to generate both the reset and arm/disarm signals reduces operator confusion.
