ABSTRACT:
A sump pump detection and alarm system, comprising electrical circuits and components to detect the existence of three different conditions, namely (1) a high water condition with electric power still available, (2) a high water condition when electrical power has failed, and (3) a failure of electrical power to the sump pump even though there is no high water level at the time, and to energize an alarm when detected to indicate which of the three conditions exists. The invention includes remote alarm stations, and in addition connections to the on-premises telephone line to produce a busy signal or other signal when such number is dialed in the event one of the three sump pump conditions exists, plus connections to a radio transmitter to transmit a radio signal when one of the said conditions exist.
