Medium voltage 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: MPA - 6600 / 50 / 3 / 60
Model Prefix: MPA
Voltage: 6600 V
HP Rating: 50 HP
Phase: 3
Frequency: 60 Hz
ACROSS-THE-LINE STARTER
MODEL MPA:
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.
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.
Introduction

6
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.

The MPA electric fire pump controller is listed cULus (Under 6600V), FM certified and 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 motor it controls and shall be within sight of the motor.
The controller shall be located or protected so that it will not be damaged by water escaping from the pump or pump
connections. Current carrying parts of the controller shall be not less than 12 in. (305 mm) above the floor level.
Working clearances around the controller shall comply with NFPA 70, National Electrical Code, Article 110 or
C22.1, Canadian Electrical Code, Article 26.302 or other local codes.
The controller is suitable for use in locations subject to a moderate degree of moisture, such as a damp basement.
The pump room ambient temperature shall be between 39°F (4°C) and 104°F (40°C).
The standard controller enclosure is rated NEMA 2. It is the installer's responsibility to insure that either the
standard enclosure meets the ambient conditions or that an enclosure with an appropriate rating has been
provided. Controllers must be installed inside a building and they are not designed for outside environment. The
paint color may change if the controller is exposed to ultraviolet rays for a long period of time.
Mounting
The fire pump controller shall be mounted in a substantial manner on a single incombustible supporting structure.
Wall mounted controllers shall be attached to the structure or wall using all four (4) mounting ears provided on the
controller with hardware designed to support the weight of the controller at a height not less than 12 in. (305 mm)
above floor level. Floor mounted controllers shall be attached to the floor using all holes provided on the mounting
feet with hardware designed to support the weight of the controller. The mounting feet provide the necessary 12 in.
(305 mm) clearance for current carrying parts.
Storage
If the controller is not installed and energized immediately, Tornatech recommend following the instructions from the
chapter 3 of the NEMA ICS 15 standard.
Wiring and Connections
Water Connections
The controller must be connected to the pipe system according to the latest edition of NFPA20 and also to a drain
pipe. The water connections are on the left side of the controller. The connection to the system pressure is a Male
½ NPT. If a drain is present, the connection to the drain is a tapered connection for plastic tubing.
Electrical Wiring
The electrical wiring between the power source and the fire pump controller shall meet the latest edition of NFPA
20, NFPA 70 National Electrical Code Article 695 or C22.1 Canadian Electrical Code, Section 32-200 or other local
codes. Electrical wiring shall be typically sized to carry at least 125% of the full load current (FLC or FLA) of the fire
pump motor.
Installation

8
Electrical Connections
A licensed electrician must supervise the electrical connections. The dimension drawings show the area suitable for
incoming power and motor connections. No other location shall be used. Only watertight hub fittings shall be used
when entering the cabinet to preserve the NEMA rating of the cabinet. The installer is responsible for adequate
protection of the fire pump controller components against metallic debris or drilling chips. Failure to do so may
cause injuries to personnel, damage the controller and subsequently void warranty.
Energy Consumption
Standby power: 10W
Sizing
Incoming power terminals on the controller are suitable to accept wire based on that selection with insulation not
less than 60°C. (Refer to terminal diagram for terminal sizes.)
The electrical wiring between the fire pump controller and the pump motor shall be in rigid, intermediate, or liquid
tight flexible metal conduit or Type MI cable and meet the requirements of NFPA 70 National Electrical Code or
C22.1 Canadian Electrical Code or other local codes.
The number of conductors required varies depending on the model of starter:
3-wires plus ground sized at 125% of full load current for models MPA, MFA.
Incoming Power Connections
Incoming normal power is to be connected to terminals located on the disconnecting means IS.
- For 3 phases motor: identified L1-L2 and L3.
- For single phase motor: identified L1 and L3
Motor Connections
Motor wires shall be connected to terminals identified by:
- T1-T2 and T3 located on main contactor (1M) for models MPA,MFA.
It is the responsibility of the installer to obtain connection information on the motor and to assure that the motor is
connected as per motor manufacturer recommendations. Failure to do so may cause injuries to personnel, damage
the motor and/or the controller and subsequently void warranty on both items.

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.
