1 Fire Pressure Governor Description
1.1 Features
The Innovative Controls Inc. Fire Pressure Governors (FPGs) are used to regulate pump discharge
pressure or engine speed in a closed-loop process control that delivers maximum accuracy and safety.
The fire pressure governor utilizes the Society of Automotive Engineers (SAE) J1939 message protocol to
control and monitor engine speed and additional engine information as required by the National Fire
Protection Association (NFPA). The fire pressure governor has an analog control option for engines that
do not support control over the J1939 network.
The FPG has four control modes: pump pressure regulation, engine speed regulation, engine high idle
regulation, and idle ramp control. The FPG uses a high speed proportional-integral-derivative (PID)
process control loop to achieve exceptional accuracy and response time. In pressure control mode the
FPG maintains a constant pump discharge pressure by adjusting the engine speed to keep the pressure
at the operator’s setpoint. The engine speed, high idle, and idle ramp control modes all use the J1939
network to regulate the engine speed to the desired setpoint. The PID control loop processor has
configuration settings that allow the FPG to be adjusted for peak performance that minimizes over-shoot,
under-shoot, and response time.
The FPG is available in two different models that offer either a rotary knob or button control of the
pressure or speed setpoint. Each model has an optional pump intake pressure sensor for improved pump
cavitation prevention. The FPG has several safety guards to prevent spikes in the pump discharge
pressure. The FPG detects no water, low water, decreasing water, and limits engine over-revving
conditions to ensure safe, reliable operation.
The FPG has configuration parameters that are used to customize its operation for a variety of vehicle
chassis types, pumps, engines, and department standard operating procedures. The configuration mode
menus are detailed in Section 3 of this manual.
The FPG can control a wide variety of engines:
Cummins with Emergency Vehicle Calibration (default)
Detroit Diesel
Mercedes
Volvo
Scania
Navistar
Mack

1.4.1 Interlocks
The FPG interlock inputs are used to enable operation of the FPG engine control functions when the
vehicle chassis is in an appropriate state. The FPG vehicle interlock logic design and implementation
have critical safety implications if not done correctly.
The Original Equipment Manufacturer (OEM) is responsible for proper interlocking of the FPG with
the vehicle chassis. Failure to do so could result in property damage, injury, or death.
The FPG has three interlock inputs: Throttle Ready, Pump Engaged, and OK To Pump. All three inputs
are turned on when vehicle battery power is applied. The Throttle Ready input notifies the FPG that the
engine is prepared to be controlled remotely. The Pump Engaged input notifies the FPG that the pump is
engaged with the engine power-take-off (PTO) so that the pump is ready to be controlled remotely. The
FPG OK TO Pump interlock condition is enabled when both the Throttle Ready and Pump Engaged
interlock inputs are active, or when the FPG OK To Pump interlock input is active and the configuration
parameter is set to OK2PUMP.
The FPG operating modes available when the interlock inputs are active and the OKTOPUMP
configuration is set to NORMAL or OK2PUMP are detailed in Table 2 below:

1.4.2 Speed Mode
The FPG speed mode regulates the engine speed at the operator’s setpoint. The FPG compares the
desired engine speed to the actual speed and increases or decreases the engine speed to bring it into
regulation.
Press the FPG front panel RPM button to place the FPG in speed control mode as long as the interlocks
are set properly as described in Section 1.4.1. The yellow LED on the RPM button is turned on when the
FPG is in speed mode and the Status Display will show “RPM Mode”.

Rev 1.10
In speed mode the FPG operates as a remote engine throttle with no regard to pump discharge
pressure. Operators must follow their organization’s standard operating procedures. Speed mode
should not be used when discharges will be opened and closed as it could result in undesired pressure
changes.
Press the FPG Pressure button to transition the FPG control from speed to pressure mode. The engine
speed will not change when the FPG mode is changed from speed to pressure. Press the FPG Idle
button to transition from speed mode to Idle mode.
1.4.3 Pressure Mode
The FPG pressure mode regulates the pump discharge pressure at the operator’s setpoint. The FPG
compares the desired pressure setting to the pump discharge pressure sensor measurement and
increases or decreases the engine speed to bring the pump pressure into regulation.
Press the FPG front panel Pressure button to place the FPG in pressure control mode as long as the
interlocks are set properly as described in Section 1.4.1. The yellow LED on the Pressure button is turned
on when the FPG is in pressure mode and the Status Display will show “PSI Mode”.
Pressure spikes or insufficient pressure can lead to potentially dangerous situations for operators
and equipment. Operators must follow their organization’s standard operating procedures. The FPG
pressure mode regulates the pump discharge pressure regardless of the number of open discharges
as long as there is an adequate water supply. Pressure mode is the preferred FPG control method as it
can respond quickly to changes in flow.
Press the FPG RPM button to transition the FPG control from pressure to speed mode. The engine speed
and pump discharge pressure will not change when the FPG mode is changed from pressure to speed.
Press the FPG Idle button to transition from pressure mode to Idle mode.
1.4.4 Idle Mode
While the FPG is controlling the engine in any mode and the Idle button is pressed, the FPG will enter the
Idle mode and ramp the engine down to the configured Idle speed. The Status Display will show “IDLE”.
The FPG relinquishes control of the engine at the idle speed and the engine returns to its curb idle speed.
The RPM IDLE configuration parameter must be set to a speed greater than the curb idle.
1.4.5 High Idle Mode
The FPG high-idle mode is used to regulate the engine speed at the value set by the HIGH IDLE
configuration parameter. The high-idle mode is used primarily to increase the engine alternator output
current to resolve low battery voltage conditions. The FPG will enter the high-idle mode if the High-Idle
and Throttle Ready inputs are activated by applying vehicle battery power. The FPG will not go into high-
idle mode if the pump is engaged. The high-idle mode engine speed can be changed using the
configuration mode menu.

active low, it provides a ground signal when the alarm is active. The alarm output is current limited to
700mA. The alarm output has two functions – a double beep alert tone and a constant alarm that is used
to warn the operator of a problematic condition.

2.4 Pressure Sensors
Use the Innovative Controls Inc. pressure sensor part numbers 3050471 or 3050472 for 0PSI to 300 or
600 PSI full scale discharge pressure. Use the 3050473 or 3050474 pressure sensors for -30PSI to 300
or 600 PSI intake pressure. Install the pump discharge pressure sensor on the discharge manifold side of
the pump. Install the pump intake pressure sensors on the intake manifold side of the pump when
applicable. The pressure sensor 300 or 600 PSI full scale range must be set in the configuration menu.
2.4.1 Pressure Sensor Installation
It is recommended that the pressure sensors be installed with the NPT measurement port facing down
and the connector facing up. This orientation will allow the pressure measurement port to drain when the
pump manifold is drained and prevent debris from damaging the sensor. The pressure sensor part
numbers and dimensions are located in Table 8 and Figure 5 below:

2.4.2 Pressure Sensor Calibration
The pump intake and discharge pressure sensors can be calibrated at 0 PSI to improve accuracy. The
pressure sensors can also be calibrated at a second point using a static pressure source to improve
linearity. The static pressure calibration point must be within 20% of the full-scale value of the sensor. The
zero and static pressure calibration parameters are located in the configuration menu.
