Abstract
The bases of an audible alarm unit and an audible/visible alarm unit are configured to be used interchangeably with a single cover. The cover has an opening that receives a projecting wall portion on the base of the audible alarm unit and a receptacle for a strobe lamp unit on the base of the audible/visible alarm unit. The bases have mounting holes that enable the alarm units to be mounted on several types of standard backboxes, the cover concealing the screw holes for good appearance of the installed units.
