Integrated emergency signaling load management system
First Claim
1. A programmable siren control system for maintaining a charged state in an energy source of an emergency vehicle comprising:
- a control module for generating siren signals and providing them to a siren that broadcasts an audible emergency signal of a type that is determined by the nature of the siren signals from the module;
a switch responsive to the module for selectively controlling the application of the energy source to an auxiliary device that broadcasts emergency signals in response to the application of the energy source to the device;
said control module including an integral load manager within the control module for controlling the switch in response to an electrical attribute of the energy source.

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.

12. A programmable emergency signaling control system for maintaining the supply voltage of an emergency vehicle battery comprising:
-
a control module electrically connectable to a siren, an external load device, and the battery, and having physically therein an integral siren control and an integral load manager; and
a control head communicatively coupled to the control module, and having disposed thereon an array of user-selectable inputs, through the manipulation of which a user may program the siren operation and a voltage-based enabling of the external load by the load manager responsive to the supply voltage. - View Dependent Claims (13)
a first output communicably linked to an engine high idle control for supplying an engine high idle enabling signal based on a comparison of the first user-programmable voltage threshold and the supply voltage;
a second output communicably linked to an audible alarm for supplying an alarm enabling signal based on a comparison of the second user-programmable voltage threshold and the supply voltage; and
