Claim 0:
1. A fire suppression system for an emergency vehicle having an engine, a transmission, a power takeoff that is mechanically linked to the transmission, and a multiplex system, said fire suppression system comprising:
a water pump that is connected to a driveline of the vehicle and is selectively engaged to receive power from the engine and transmission through the power takeoff;
a pressure governor control that is configured to allow an operator to selectively command a power resource request directly to the engine to change a speed of the engine driving the water pump;
a system controller having a processing circuit that is in communication with each of the engine, the multiplex system, and the pressure governor control, said processing circuit being configured to determine an operational state of an interlock that enables an engine speed control via the multiplex system, and to allow the engine power resource command based on the operational state of the interlock; and
an operator actuator that is in communication with the system controller, said actuator being configured to allow an operator to selectively command another power resource request to the engine via the system controller to change a speed of the engine driving the water pump.
