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 can be stopped manually with the local stop pushbutton or automatically after the
restauration of the pressure in the sprinkler system. 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: HFA - 208 / 160KW / 3 / 60
Model Prefix: HFA
Voltage: 208 V
HP/KW Rating: 215HP / 160KW
Phase: 3
Frequency: 60 Hz
ACROSS-THE-LINE STARTER
MODEL HFA:
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.
MODEL HFS: 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.
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 HFW: 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 HFY: WYE-DELTA OPEN TRANSITION STARTER
This type of starter requires a multi-connection motor and 6 conductors between the controller and the
motor.
Introduction

6
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
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.
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.
AUTOMATIC STOP
Automatic stop is possible only after an automatic start and if this function has been activated. When this function
is enabled, the motor is automatically stopped 10 minutes after the starting request is no longer present.

Quick Start-Up Guide
The rating label is the most important label. It must be read carefully to ensure the compatibility between the
controller and the installation.
Verify that the controller is installed securely on the wall, or optionally on the mounting stand.

11
Make sure to drill holes for the motor and power connections and run the cables inside the panel, all in accordance
with the specifications in order to minimize interference with other equipment.
Connect the input power and the motor on their respective terminals. Secure with the appropriate torque as
indicated on the torque label and verify all connections. Secure the door in closed position then put the circuit
breaker disconnecting means in ON position. Verify the readings on the controller main screen.

12
Verify the motor rotation to ensure that the pump is turning in the right direction. The START and STOP push
buttons can be used to toggle the motor ON/OFF.
WARNING!
On a Wye-Delta closed transition starter, if the transition from Wye to Delta occurs (after 5 to 8 seconds depending
on the motor HP), the manual stop push button will be disabled for 80 seconds. To stop the engine before the end
of the 80 second delay, use the disconnecting mean handle.

Alarms
Displays the list of currently active and occurred alarms. An alarm is called ACTIVE when its triggering condition is
still valid. An alarm is called OCCURRED when its triggering condition has been active, but is no longer true.
Alarms representing serious concerns are colored RED. Alarms representing simple warnings are colored
YELLOW. To silence the bell press the ALARM button or it will silence itself after the expiration of a factory set
timer. Pressing on the RESET button will reset OCCURRED alarms only. Alarms ending with ** are available on
transfer switch models only.
The table displays system events:
- Date and Time: Date and time stamp of the alarm in the YYYY.MM.DD format
- Message: Alarm message
- State: OCCURRED or ACTIVE
- Color Code:
- Red: The event is an alarm
- Yellow: The event is a warning
Complete list of alarms :
- Normal Phase Reversal: Activates when the phase order on the normal power does not match the correct value of
the controller. Each time a service is acknowledged on the ViZiTouch, the controller synchronises the correct phase
order to the one detected on the normal power.
- Phase Loss N1: This alarm is activated if the first phase of the normal power connection does not meet the
qualification criteria.
- Phase Loss N2: Activates if the second phase of the normal power connection does not meet the qualification
criterions.
- Phase Loss N3: Activates if the third phase of the normal power connection does not meet the qualification
criterions.
- Loss of power: Activates when a complete loss of normal power is detected.
- Fail to start: Activates if there is and under-current draw of two phases when the motor should be running. A 20
seconds factory set delay is used to give the motor enough time to start before signalling this alarm.
Alarms

20
- Undercurrent: Activates when current is under 30% of FLA and motor has been running for 15 seconds.
- Overcurrent: Activates when current is above 120% of FLA.
- Under voltage: Activates when normal power voltage is below 80% of nominal voltage.
- Over voltage: Activates when normal power voltage is above 120% of nominal voltage.
- Phase Unbalanced: Activates when there is a difference of more than 10% of nominal voltage between the normal
power voltage readings.
- Ground Fault: Activates when the ground fault input current is above the factory set value after a factory set delay.
- Water Reservoir Low: Activates if the “Water Reservoir Low” contact input is triggered or if the analog readout of
the water reservoir is enabled and is lower than the water reservoir low set point in the “Water Level” sensor page.
- Control Voltage Not Healthy: Activates when the 24VAC power input to the IO cards is below the acceptable
functional range.
- Motor Trouble: Activates when a motor related alarm condition is present (overcurrent, undercurrent, fail to start or
ground fault).
- Pump Room Alarm: Activates when a pump room related alarm condition is present (overvoltage, undervoltage,
phase unbalanced).
- Pump on demand: Activates when an automatic starting request is active.
