Abstract

See full text

A home safety unit having an emergency light system for providing light in the event of a power failure or the detection of a fire condition, and a fire detection system for providing an alarm indicating the existence of a fire. The safety unit is designed to have an aesthetically pleasing appearance and to be installed inconspicuously between the base of an existing light fixture and a wall or ceiling. Installation of the safety unit is a simple process, whether installing it when constructing a new building or by retro-fitting it into an existing building. A modified light switch having parallel impedance across the light switch terminals is installed to provide continuous power to the safety unit when the switch is in its off position. Also included is a low voltage dropout system for disconnecting the auxiliary lights when the battery voltage falls below a certain level and for providing an audible alarm indicating this low voltage condition.
