ABSTRACT:
A system for sensing smoke and fire, primarily through the sensing of associated carbon monoixide and optionally with supplementary heat sensing, and for sensing hazardous gases and vapors. The system senses the presence of carbon monoxide, even in the absence of fire and is capable of sensing the presence of hydrogen and hydrocarbon vapors such as methane and propane. Additionally, the volatile vapors of paints, varnishes and other household and industrial substances are detectable. The system also includes circuitry and equipment for notification and warning of such detection, together with circuitry and equipment for providing emergency operation in the event of normal power failure. Further circuitry and equipment for self-monitoring of system remote wiring and sensor integrity, and associated notification means for such integrity checks is included. The system provides for the use of a suitable multitude of sensor devices located remotely from a main control unit, so that sensor device locations may be chosen to maximize the possibility of detecting the presence of smoke, fire or the gases and vapors previously described. The system also includes a novel form of sounding device, of the type wherein an electro-magnet causes a hammer to strike a sounding apparatus with such sounding devices being suitable for use in flammable, combustible or otherwise reactive atmospheres.
