Abstract
A smoke detector or alarm includes on its lower side a cylindrical cup which may be lined with ribbed foam rubber. The inside diameter formed by the liner is designed to mate with the end of a broom or mop handle so that the cup forms a reasonably firm fitting socket for the handle end. A wedge shape triangular adapter plate is mounted on top of the smoke detector and slightly spaced from the top by a round vertical stud. Secured either directly to the ceiling or to the usual smoke detector mounting fasteners is a receiver into which the adapter plate fits. The receiver is in the form of a horizontal wedge shape triangular slot, the bottom of which has a blind slot to accommodate the stud of the adaptor. The bottom of the entrance to the receiver is provided with a lip over which the adapter plate must move. The smoke alarm may accordingly be readily removed and replaced for battery changing, servicing, and testing without the use of a step ladder or step stool. The adapter, receiver and cup form the major components of a kit which may be applied to new or existing smoke detectors.
