Abstract
A detector assembly is adapted to be removably secured to a female electrical receptacle connected to a power supply where the female receptacle is mounted at a surface of a structure. The detector apparatus includes a housing and an electrically powered circuit mounted in the housing. The circuit includes components operable to detect an alarm condition (such as carbon monoxide or smoke) and to provide an alarm in response to the detection. A primary power source includes a male electrical connector secured to the housing and extending outwardly there from. A secondary power source includes a battery connector mounted within the housing and adapted to removably receive a battery contained within the housing. The circuit is adapted to draw power from the secondary source in the event of a detected loss of power from the primary source. The apparatus includes a sensor for sensing displacement of the housing from the female electrical receptacle. The circuit is adapted to provide an alarm in response to the displacement of the housing from the mounted surface.
