ABSTRACT:
A generally square mounting plate for attaching the cover of an audible-visual alarm to a backbox includes a plurality of openings along each side of the plate. The openings are configured and positioned to accommodate the mounting bolt placement of various standard backboxes, including 4-inch, international, single-gang and double-gang backboxes. Indicia are provided on the front of the plate to guide the installer in the correct assembly of the plate to the backbox to provide a desired orientation of a feature of the alarm, advantageously a strobe unit. The alarm generating components, e.g., a strobe unit and/or an acoustic transducer, may be carried either by the alarm cover or by the mounting plate.
