Abstract

An emergency signaling system with integrated load management functionality is provided wherein the load management circuitry is alternatively operable in programming and operating modes. The system includes a keypad, control head, control unit and a plurality of signaling features selectively activated by the control unit in the operating mode. The load management circuitry automatically sheds loads from the signaling system in response to an indication from the electrical system powering the signaling system that an energy drain is occurring at the energy source that will cause disruption to other more important systems—e.g., the ignition system in a vehicle.
