Abstract
Abstract The detector assembly combines an electrically powered detector and alarm and an electrical light into a single unit which is removably attachable to a conventional electrical receptacle. The unit includes a closed housing containing a detector and alarm system, and recessed within the housing is a light bulb socket for reception of a light bulb into a face of the housing. Protruding from an opposite face of the housing is an electrical connector capable of removable attachment to a standard electrical receptacle. A sound transmitter in the housing may transmit audible alarm signals to a remote receiver, which may be mounted in another detector assembly at a remote location to cause this detector assembly to emit alarm signals.
