ABSTRACT:
A housing has two openings to receive the electrically conductive prongs of a plug to mount the housing and a third opening to receive the grounding prong. Electrically conductive strips are disposed within the housing and have the conductive prongs of the plugs, which pass through the two openings in the housing, pass through openings in the electrically conductive strips to be in contact with the strips to provide a source of power to the strips, which are electrically connected to an alarm circuit. The alarm circuit produces an audible signal whenever there is no current through the plug due to a power failure or the plug being removed from its power source and a battery, which is supported within the housing, is connected to this alarm circuit.
