ABSTRACT:
A smoke alarm having means for detecting smoke and producing a signal in response to the detected smoke is provided with a manually-actuated control which cooperates with the signal producing means to temporarily deactivate the same and to automatically reactivate the same after a predetermined time delay. A temperature responsive override switch is provided to actuate the signal in the event of a fire during the time delay. Thus, a homeowner is able to temporarily deactivate the smoke alarm, such as duringcooking, parties, showering, etc. to thereby prevent the alarm from going off in response to non-fire conditions.
