PART WINDING
ELECTRIC FIRE PUMP CONTROLLER
STANDARD DRAWING PACKAGE
NOTE: The drawings included herein are for standard controllers.
Actual "as built" drawings may differ from those seen here.
IM-1250
Description桭iretrol
FTA1250 Part Winding Start-
ing Fire Pump Controllers can be used where the char-
acteristics of the power source do not permit full volt-
age starting. The controller monitors, displays and
records fire pump system information.
When the controller is actuated by the pressure
switch, START pushbutton, deluge valve contact, etc.,
the first contactor closes, connecting one of the mo-
tor windings to the line. During starting, the motor will
draw approximately 65% of its normal locked rotor
current and develop approximately 42% of its normal
starting torque. After a time delay, the second
contactor closes, connecting the second winding in
parallel with the first. The motor then draws its normal
running current and develops its rated torque.
Approvals桭iretrol fire pump controllers are listed
by Underwriters' Laboratories, Inc., in accordance with
UL218, Standard for Fire Pump Controllers, CSA,
Standard for Industrial Control Equipment, and ap-
proved by Factory Mutual. They are built to meet or
exceed the requirements of the approving authorities
as well as NEMA and the latest editions of NFPA 20,
Installation of Centrifugal Fire Pumps, and NFPA 70,
National Electrical Code.
Standard Features桾he following are included as
standard with each controller:
n Voltage surge protector
n Main Disconnect Switch sized for connected mo-
tor horsepower and voltage
