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: GPA - 208 / 50 / 3 / 60

Model Prefix: GPA

Voltage: 208 V

HP Rating: 50 HP

Phase: 3

Frequency: 60 Hz

ACROSS-THE-LINE STARTER

MODEL GPA:

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 GPP: PART WINDING STARTER

This model requires the use of a motor with two separate windings and 6 power conductors between the

controller and the motor.

Upon a start command, the first winding is connected to the line immediately. The second winding is

connected to the line after a very short time delay.

MODEL GPR: 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 GPS: 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.

Introduction

MODEL GPV: ACCELERATION RESISTOR 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 set of acceleration resistors in each phase is utilized to supply a reduced voltage

to the motor. After a time delay, the resistors are shunted out and the motor is connected to full voltage by a

closed transition switching sequence.

MODEL GPW: 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.

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 GPY: 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.

Types of Automatic Transfer Switch

TRANSFER SWITCH CATALOG NUMBER

MODEL No. EXAMPLE: GPA+GPU - 480 / 20 / 3 / 60

Model Prefix GPA+GPU

Voltage 480 V

HP Rating 20 HP

Phase 3

Frequency 60 Hz

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.

FLOW START, HIGH ZONE START

The pump can be started by opening/closing a contact on the FLOW/ZONE START/STOP input.

WEEKLY START

The engine can be started (and stopped) automatically at the preprogrammed time.

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.

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.

FLOW STOP, HIGH ZONE STOP

If the controller has been started by the FLOW/ZONE START/STOP input and the signal has returned to normal,

the motor will be stopped 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.

Transfer switch operation Sequence

TRANSFER TO ALTERNATE POWER SOURCE

The Transfer to Alternate Power Source starts automatically when at least one of the following conditions are

present:

- Normal Power voltage falls below 85% of nominal voltage,

- Normal Power Phase Reversal is detected,

- Transfer Switch Test push button is pressed.

When an under voltage condition on any phase of the Normal Power source is detected by the sensor, a 3 second

normal power source outage delay timer starts timing.

If the normal source voltage rises above the sensor dropout setting before the 3 second time delay expires, the

transfer sequence is cancelled.

If the Normal Power source voltage is still below the sensor dropout setting (85%) when the time delay expires, a

relay is deactivated sending a signal to start the generator set. At the same time, a voltage and frequency sensor

begins monitoring the Alternate Power Source. The sensor will accept the alternate power source only when both

voltage and frequency reach a pre-set pickup value. An approximate 15 second time span occurs because the

engine-driven generator cranks, starts and runs up to nominal pickup value.

When the Alternate Power Source is within acceptable limits (above 90% of the nominal voltage) for a certain set

time (factory set at 3 seconds), the transfer to alternate power source is initiated.

The transfer switch will remain in the alternate power source position until the normal source is restored.

RETRANSFER TO NORMAL

Important: The transfer switch will stay in alternate position, if the motor is running, for as long as the alternate

power source is within acceptable limits. The retransfer sequence is enabled if the motor is not running.

The Retransfer to the Normal Power source starts when the voltage sensor detects restoration of the Normal Power

Source within acceptable limits. The voltage level must rise above the pre-set pickup value (90%) on all phases

before the sensor will accept the normal source.

When the normal source is accepted by the sensor, the retransfer to normal delay timer starts timing (factory set at

5 minutes). This delay can be by-passed by pressing on the count-down timer displayed on the screen (if a flashing

“X” is displayed).

This delay prevents immediate load retransfer to the normal source. The delay insures that the normal power

source has stabilized before reconnection of the Fire Pump Motor. If the normal source voltage falls below the pre-

set dropout value before the time delay expires, the timing cycle is reset to zero. If the alternate power source fails

during the timing cycle, the load is immediately retransferred to the normal source, if that source is acceptable.

The Automatic Transfer Switch is now feeding the Fire Pump Motor from the Normal Power Source again.

Upon retransfer to the normal source, the 5 minute cooling timer starts counting down, keeping the engine running

during this cool-down period. This delay can be by-passed by pressing on the count-down timer displayed on the

screen (if a flashing “X” is displayed).

After the time delay, the relay is re-activated to shut down the engine-driven generator. All circuits are reset for any

future normal source failure.

Every time the transfer switch needs to change from one power source to the other, a running motor is stopped

during the transfer to prevent instant across the line starting of an already turning motor. If the motor still needs to

run when the transfer sequence has completed (plus a factory set 2 second timer), the motor will be restarted

following its default start-up sequence.

Manual Operation of the Transfer Switch

There is 180° between the Normal position (I) and the Alternate position (II). To operate manualy the Transfer

Switch:

1 - Use the Disconnect Switches to turn OFF the power of both Normal and Alternate sides.

2 - Open the door of the Alternate side.

3 - On the Transfer Switch, put the selector switch in Manual mode.

4 - Take the handle, situated inside the controller door and insert it in the square hole on the Transfer Switch.

5 - Turn the handle clockwise 180° to transfer from Alternate to Normal position.

Turn the handle counterclockwise 180° to transfer from Normal to Alternate position.

6 - Remove the handle and put it back on the support inside the controller door.

7 - On the Transfer Switch, put the selector switch in Automatic mode.

8 - Close the door and using the disconnecting switch handles put back the power on both sides.

BE CAREFUL:

- Do not close the controller door if the handle is still installed in the Transfer Switch.

- Do not operate manualy the Transfer Switch if the Normal side power is still ON.

- Do not forget to replace the Transfer Switch in Automatic mode.
