Sensor alarm and support
First Claim
1. A sensor alarm support for use with a door mounted in a door frame having a door head and two door jambs and hinged on one door jamb to swing closed and latched against the other door jamb comprising:
- a mounting plate;
one side of said plate adapted to have mounted thereon a sensor and an alarm coupled to said sensor;
an angle arm being affixed to the top edge of said plate and having a transverse portion extending transversely from the other side of said plate;
a flange depending from said transverse portion and being transversely spaced from and substantially parallel to said plate whereby said plate and arm form an inverted channel snugly fittable over the top door edge;
a stiffly resilient bumper pad being affixed to the outer side of said flange and being positioned on said flange so that the edges of said pad and an edge of said flange are substantially flush, whereby, when said door is in its latched position, a pad portion will be between a corresponding door edge and at least one of said door head and said other door jamb to forcibly cock said door open to provide a clearance for a gaseous path.

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.
