Claim 7:
8. A method of controlling a fire suppression system for an emergency vehicle having an engine, a transmission, a power takeoff that is mechanically linked to the transmission, a multiplex system, a water pump, a pressure governor control system enabled by a safety interlock system, and a system controller having a processing circuit that is in communication with an operator actuator device, said method comprising:
receiving, via one of the pressure governor control system, a power resource command to change a speed of the engine driving the water pump;
receiving, via the multiplex system, an operational state of a safety interlock that enables a speed control of the engine mechanically coupled to the water pump;
identifying, via the processing circuit, an error notification whereby the power resource command and the safety interlock are conflicting;
enabling, via the processing circuit, a manual override control of the operator actuation device;
receiving, via the processing circuit, an operational request from the actuation device in communication with the system controller; and
providing an engine resource request, via the processing circuit, whereby the operational request functions to override or replace an engine request command of the pressure governor control.
