1. A water detector system for the detection of standing water indicative of an abnormal condition in a building or other habitable structure, said system comprising:

  • a power circuit comprising at least two electrically conducting leads, each of said leads electrically connected at one end to an input which is electrically connected to a source of alternating current, each of said leads electrically connected at their respective other ends to an output which is electrically connected to an electrical appliance which is to be protected, said electrical appliance receiving its electrical power through said leads of said power circuit;

    means, electrically connected intermediate said power circuit input and output and connected to each lead of said power circuit, for providing control of said power circuit, said means for providing control including isolating means for protecting personnel from the hazards of electrical shock from contact with said source of alternating current;

    means, connected to said means for providing control, for initiating alarm signals and control signals responsive to the detection of standing water, said control signals triggering said means for providing control of said power circuit to disconnect said protected electrical appliance from said source of alternating current; and

    ,a plurality of water sensors connected to said means for initiating alarm signals and control signals, said water sensors capable of detecting standing water.
