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

1.3 Front Panel
The FPG control switches, indicators, and displays are located on the front panel. Refer to Figure 1
below. The indicators can be configured to automatically adjust their brightness based on ambient light
conditions or manually set to one of ten different fixed levels. The control switches are designed for
reliable operation by users wearing gloves. The front panel components are described in the following
sections.

1.3.2 Engine Speed Display
The Engine Speed Display shows the engine speed in revolutions per
minute (RPM).
1.3.3 Pump Discharge Pressure Display
The Pump Discharge Pressure Display shows the pump pressure in
PSI, kPa, MPa, or bar as measured by the discharge sensor.
1.3.4 Throttle Ready Indicator
The Throttle Ready Indicator shows the status of the Throttle Ready interlock input. This
indicator is green when the Throttle Ready input is active.
1.3.5 OK To Pump Indicator
The OK To Pump Indicator shows the status of the OK To Pump interlock input. This
indicator is green when both the Throttle Ready and Pump Engaged inputs are active, or
when the OK 2 Pump input is active and the configuration parameter is set to OK2PUMP.
1.3.6 Engine Coolant Temperature Indicator
The Engine Coolant Temperature Indicator changes color to show the state of the engine
temperature. Green indicates normal temperature, yellow when the temperature is in the
warning range, and red when the temperature is critically high. The engine coolant
temperature indicator can be configured to operate from standard J1939 diagnostic
message failure mode identifiers or from user defined setpoints.
1.3.7 Engine Oil Pressure Indicator
The Engine Oil Pressure Indicator changes color to show the state of the engine oil
pressure. Green indicates normal oil pressure, yellow when the oil pressure is in the
warning range, and red when the oil pressure is critically low. The engine oil pressure
indicator can be configured to operate from standard J1939 diagnostic message failure
mode identifiers or from user defined setpoints.

1.3.8 Transmission Temperature Indicator
The Transmission Temperature Indicator changes color to show the state of the
transmission temperature. Green indicates normal temperature, yellow when the
temperature is in the warning range, and red when the temperature is critically high. The
engine coolant temperature indicator can be configured to operate from standard J1939
diagnostic message failure mode identifiers or from user defined setpoints.
1.3.9 Battery Voltage Indicator
The Battery Voltage Indicator changes color to show the state of the vehicle system
voltage. Green indicates normal battery voltage of 12.5V or greater, yellow when the
voltage is in the warning range between 11.9 and 12.5VDC, and red when the voltage is
critically low at 11.8VDC or less. The battery voltage is measured directly at the FPG DC
power input. The battery voltage measurement has a configurable offset that can be used
to handle voltage drops between the battery and the FPG.
1.3.10 Pressure Mode Button
The Pressure button places the FPG in pressure control mode. The LED indicator is
green when the FPG is in pressure control mode. On the 3050621 and 3050622
models of the FPG, holding the pressure mode button while pressure mode is
engaged will display status messages on the status display (see 1.4.6 for a detailed
list of messages).
1.3.11 RPM Mode Button
The RPM button places the FPG in speed control mode. The LED indicator is green
when the FPG is in speed control mode. On the 3050621 and 3050622 models of the
FPG, holding the RPM mode button while RPM mode is engaged will display status
messages on the status display (see 1.4.6 for a detailed list of messages).
1.3.12 Preset Button

curb idle speed. On the 3050621 and 3050622 models of the FPG, holding the idle
button while no mode is engaged will display status messages on the status display
(see 1.4.6 for a detailed list of messages).
1.3.14 Increment/Decrement Buttons
The pump pressure or engine speed setpoint is controlled by the + and – buttons on
the 3050621 and 3050622 models of the FPG. The + and – buttons are also used to
adjust configuration settings when the FPG is in the configuration menu mode.
1.3.15 Increment/Decrement Knob with Idle Button
The pump pressure or engine speed setpoint is controlled by the rotary knob on the
3050623 and 3050624 models of the FPG. The direction the knob is turned to cause
an increase in the setpoint value is configurable to be either clockwise or
counterclockwise. The rotary knob is also used to adjust configuration settings when
the FPG is in the configuration menu mode. The rotary knob has an integral Idle
button that is used to end the engine control session and place the engine in the
curb idle speed.
1.3.16 Status Button
The status button is used to display status messages on the status display (see
1.4.6 for a detailed list of messages). The status button is available on the 3050623
and 3050624 models of the FPG.
1.4 Operation
The FPG has six modes of operation that are used for specific pump and engine control applications:
initialization, ready, speed control, pressure control, high-idle control, and idle. The configuration mode is
used to edit FPG system parameters. The configuration mode menu can only be entered from the ready
mode when the FPG is not controlling the engine. The following sections detail the operation of the FPG
control modes, the required interlocks, warnings, and alarms.
