1. A safety control system comprising:

  • a transmitter;

    a power source for providing power to the transmitter;

    a repeat cycle timer that provides a repetitive input cycle separated by a repetitive time delay, the input cycle causes a circuit to close and cause the transmitter that is powered by the power source to transmit a signal during the input cycle;

    a receiver for receiving the signal from the transmitter;

    a power source for providing power to the receiver;

    a time delay relay that latches upon receipt of the signal by the receiver to close a circuit and provide power to a pump unit for a fixed amount of time, and the time delay relay continues to remain latched upon repetitive receipt of the signal by the receiver thereby continuing to close a circuit and continuing to provide power to the pump unit for a subsequent fixed amount of time.
