Abstract

See full text

An emergency lighting fixture, for plug-in installation in a wall connector mounted protruding from a fixed wall plate, has a back plate secured to its wall-engaging face. The back plate and the wall plate are provided with interfitting flanges and a pivoted latch secures the plates together in facing juxtaposed engagement. A mating multi-prong plug and socket connects A.C. line power from the wall connector to internal circuitry in the lighting fixture for lighting a lamp, for charging a rechargeable internal battery and for operating a transfer circuit to deliver battery power in the event of line power failure. The conductor from one terminal of the battery is connected to said circuitry by two prong-and-socket pairs, in the multi-prong plug and socket, which are connected by a permanent jumper conductor in the wall connector, affording battery isolation in the lighting fixture until its plug-in installation in the wall connector is completed.
