ABSTRACT:
A modular alarm system includes a plurality of sensing devices, each of which is adapted to sense the presence or absence of a particular condition, specifically a fire or over heat condition (hereinafter referred to merely as a fire condition), and the presence or absence of a fault including a short circuit or open circuit. The system also includes a detector module for producing an equal plurality of identical logic output signals indicative of and in response to the presence of the particular condition being monitored at the various sensing devices and a single, identical logic output signal indicative of and in response to the presence of a fault at any of the sensing devices. In addition, the system may include a main control module, a relay module and a zone module which functionally interconnect with one another and with the detector module by means of identical logic output signals and which, along with the detector module, preferably include their own power regulators and capacitive filtering systems.
