ABSTRACT:
The present invention relates to a device for automatically disabling power to an electrical appliance as a fire erupts. The device includes a plurality of combustion product gas sensors disposed within or proximal to an electrical appliance each in communication with an audible alarm and an electrical contactor via a relay. The electrical contactor is received within an auxiliary plug which is coupled with the appliance plug such that, when the sensors detect a predetermined concentration of carbon dioxide or carbon monoxide, the contactor opens to disable power to the appliance and an audible alarm is simultaneously emitted.
