Electric fire pump controllers are designed to start an electric motor driven fire pump. It can either start the fire
pump manually through the local start pushbutton or automatically through the sensing of a pressure drop in the
sprinkler system. The fire pump controller is supplied with a pressure transducer. The fire pump can be stopped
manually with the local stop pushbutton or automatically after the expiration of a field programmable timer. In both
cases, stopping is only allowed if all starting causes have disappeared.
Types of Electric Fire Pump Controllers
FIRE PUMP CATALOG NUMBER
MODEL No. EXAMPLE: GFA - 208 / 160KW / 3 / 60
Model Prefix: GFA
Voltage: 208 V
HP/KW Rating: 215Hp / 160KW
Phase: 3
Frequency: 60 Hz
ACROSS-THE-LINE STARTER
MODEL GFA:
This model is intended to be used where the local utility or the capacity of the power source permits across-
the-line starting.
Full voltage is applied to the motor as soon as the controller receives a start command.
REDUCED VOLTAGE STARTERS
These models are intended to be used where the local utility or the capacity of the power source does not permit full
voltage starting.
In all the reduced voltage models, the manual “EMERGENCY RUN” device will initiate across-the-line starting.
MODEL GFR: AUTOTRANSFORMER STARTER
This model does not require a multi-connection motor. It only requires 3 conductors between the controller
and the motor.
Upon a start command, an autotransformer is utilized to supply reduced voltage to the motor. After a time
delay, the autotransformer is shunted out and the motor is connected to full voltage by a closed transition
switching sequence.
MODEL GFS: SOLID STATE STARTER
This model does not require a multi-connection motor. It only requires 3 conductors between the controller
and the motor.
Upon a start command, a solid-state starter is utilized to supply a step less ramp-up voltage to the motor
until the motor reaches its full speed. At that time, a fully horsepower rated by-pass contactor is energized
connecting the motor directly to full voltage and eliminating all heat loss within the solid-state starter.
This controller also features a soft motor stopping mode and a hard stop mode. For a hard stop, hold the
stop pushbutton until the motor stop.
MODEL GFW: WYE-DELTA CLOSED TRANSITION STARTER
This model requires a multi-connection motor and 6 conductors between the controller and the motor.
Upon a start command, the motor is connected to the line in the wye connection. After a time delay, the
motor is reconnected to the line in the Delta configuration applying full voltage to the motor windings by a
closed transition switching sequence.
Introduction

6
The power source does not « see » any open circuit during the transition from wye to delta. During the
transition from Wye to Delta, a resistor bank is connected in the starting circuit and allows to keep the motor
coils energized. An 80 second delay is then triggered and prevent the motor from stoping. This delay allows
the resistors to cool down and will only be triggered if the transition occur. An emergency stop can still be
perform by pulling the disconnecting mean handle.
MODEL GFY: WYE-DELTA OPEN TRANSITION STARTER
This type of starter requires a multi-connection motor and 6 conductors between the controller and the
motor.
Upon a start command, the motor is connected to the line in the Wye connection. After a time delay, the
motor is reconnected to the line in the Delta configuration applying full voltage to the motor windings. This
controller is of the open transition type. The motor is disconnected from the line during the transition from
start (wye) to run (delta) mode.
Methods of Starting/Stopping
The controllers are available as combination automatic / non-automatic with provision for manual or automatic
shutdown (an automatic shutdown is only possible after an automatic start).
METHODS OF STARTING
AUTOMATIC START
The controller will start automatically on low pressure detection by the pressure sensor when the pressure drops
below the cut-in threshold.
MANUAL START
The motor can be started by pressing the START push button, regardless of the system pressure.
REMOTE MANUAL START
The motor can be started from a remote location by momentarily closing a contact of a manual push button.
REMOTE AUTOMATIC START, DELUGE VALVE START
The motor can be started from a remote location by momentarily opening a contact connected to an automatic
device.
EMERGENCY START
The motor can be started manually by using the emergency handle. This handle can be maintained in a closed
position.
Important: to avoid damaging the contactor, it is recommended to start the motor in this manner:
1) Shutdown the main power by using the main disconnect means,
2) Pull the emergency handle and lock it in closed position,
3) Turn the power back on by using the main disconnect means.
SEQUENTIAL START
In case of a multiple pump application, it may be necessary to delay the automatic (pressure drop) starting of each
motor to prevent simultaneous starting of all motors.
TEST START
The motor can be started manually by pressing the run test button.
METHODS OF STOPPING
MANUAL STOP
Manual stop is done by pressing the priority STOP push button. Note that pressing the stop push button will
prevent the motor from restarting as long as the button is pressed, plus a two second delay.

7
AUTOMATIC STOP
Automatic stop is possible only after an automatic start and this function has been activated. When this function is
enabled, the motor is automatically stopped 10 minutes after the restoration of the pressure (above the cut-out
threshold) given that no other run cause is present.
EMERGENCY STOP
The emergency stop is always possible in any starting condition and is done by using the main disconnecting
means located on the door.

The GFx electric fire pump controller is intended to be installed in accordance with the Standard of the National Fire
Protection Association for the Installation of Centrifugal Fire Pumps, NFPA n°20-2013 (Centrifugal Fire Pumps) and
in USA National Electrical Code NFPA 70
in Canada Canadian Electrical Code, Part 1
others * Local Electrical Codes *
*Only American and Canadian applicable codes have been considered during the design of the controllers and the
selection of components.
Location
The controller shall be located as close as practical to the engine/motor it controls and shall be within sight of the
engine/motor. The controller shall be located or protected such that it will not be damaged by water escaping from
pump or pump connections. Current carrying parts of the controller shall be not less than 12 in. (305 mm) above the
floor level.
