ABSTRACT:
A sensor alarm has a sensor for detecting heat, smoke, noxious gases, and the like and an alarm for warning of an alarm condition coupled to the sensor. The sensor alarm is attached to a support plate. An angled arm is formed at the upper edge of the plate to provide an inverted channel-shaped member fittable over a door top and having stiffly resilient pads for forcibly cocking the door top open, when the door is closed and latched, to provide a path for gaseous passage so that room occupants are provided with an early warning of an alarm condition.
