  • System for automatically shutting down auxiliary power devices in a vehicle
    Patent number: 4864154
    Abstract: A solid state digital and analog circuit which is connected between a two-way radio, public address system etc. and the battery in a police car, emergency vehicle, tow truck or fire truck to prevent the same from inadvertently draining all the power from the battery when the vehicle is left unattended for long periods of time. When the ignition is turned off, a timer in the circuit begins counting and after a prescribed amount of time, e.g. between one and twelve hours, a relay disconnects the auxiliary equipment from high current of the battery. When the ignition is turned on the circuit immediately re-connects the auxiliary equipment and the battery.
