ABSTRACT:
In a preferred embodiment, a fire extinguishing system for suppressing fi on cook stoves, fryers or other heating or heated devices with fire suppressant dispensed through nozzles is powered by batteries which provide current for both a detection circuit including a pair of heat sensors and control circuitry and current for a gas or electric house current shut-off. Preferably, the shut-off is operated acoustically upon sounding of an audible alarm which emits a signal to which the shut off is acoustically tuned. Preferably, the heat sensors are diodes but, in alterative embodiments may be thermistors or active temperature sensors. While a wireless link, such as an acoustical link, is preferred between the control circuitry and shut-off, a wired link may also be used. In order to facilitate mounting of both the heat sensors and nozzles, magnetic housings are utilized which retain studs extending from tees, 90 degree elbows or both. A heat sensor housing is secured to the magnetic mount by magnetic force, which heat sensor housing is in turn held securely proximate the heat source at appropriate locations.
