ABSTRACT:
A fire extinguishing system for a cookstove or range includes a fire extiisher mounted above a hood positioned over the cookstove or range. The fire extinguisher is connected to a pair of nozzles within the hood to dispense fire suppressant over the cookstove or range. The fire extinguisher includes an operator normally biased to the operable position, but held in the inoperable position by a cable having a plurality of fusible links distributed therein. The cable is held in tension adjacent the inner periphery of the hood. Upon the occurrence of a fire, at least one of the links separates, releasing the cable and allowing the operator to move to the operating position whereby the fire extinguisher releases the fire suppressant. A low-voltage control circuit is used to cut off the flow of electricity or gas to the stove and to sound an alarm. A battery is provided with the low-voltage control circuit so that the system will still operate if house current is interrupted.
