Abstract: The present invention is an ASIC-controlled alarm unit. The ASIC circuit performs all the necessary control functions to provide audible and visual signaling when used with external horn and strobe circuits.

Abstract: A mounting plate assembly for a notification appliance is disclosed. For example, a mounting plate is designed with at least one aperture for receiving a plurality of leads, e.g., from a backbox. In turn, these leads can be received by a plurality of contacts that are deployed on the mounting plate. In one embodiment, at least two of these contacts are in physical contact with each other at a juncture, thereby providing connectivity between these two contacts. However, the physical contact at the juncture is non-resettable, i.e., if a force is applied to the juncture, then the connectivity is severed and the physical contact between the two contacts cannot be easily re-established even if the force is removed.

Abstract: An audiovisual signaling device includes in electrical connection: (a) an auditory output portion which produces an auditory output and a corresponding low voltage oscillatory signal; (b) a converter portion which is responsive to and converts the low voltage oscillatory signal to a repetitively produced corresponding high voltage intermittent spike signal; (c) a visual output portion which produces a visual output; and (d) a portion responsive to the high voltage intermittent spike signal to repetitively activate the visual output.
