The Manual Wound Rotor Motor Standpipe Fire
Pump Control Panel shall be factory assembled,
wired and tested, in accordance with the specific
requirements of the Standpipe Rules, City of New
York, Department of Buildings, Material & Equipment
Acceptance Division.
The controller shall be U.L. Listed & NYC Approved
MEA Department.
The controller shall be designed for manual starting
and speed regulated and shall be of the reduced
voltage secondary resistance type with five (5) steps
of speed control for operating the wound rotor motor
driving the Fire Pump.
All controller components, including circuit breaker
and contactors, shall be front mounted, front wired
and front accessible for maintenance. The minimum
withstand rating of the controllers shall not be less
than 100,000 Amps RMS Symmetrical at 200-480
Volts, and 22,000 Amps RMS Symmetrical at 550-
600 Volts.
The controller shall consist of sectionalized panels
enclosed in a drip proof, free standing cabinet con-
structed of not less than No. 12 gauge sheet metal.
The rear of the enclosure shall be provided with
ventilated removable cover plate and the front shall
have a hinged door with 3 point catch and handle.
On the front section of the cabinet, to be visible with
the doors closed, there shall be mounted:
1- AC Ammeter
1- AC Voltmeter
1- Pilot light with white lens to indicate "Control
Power Available"
1- Pilot light with red lens to indicate "Pump Run-
ning"
The controller shall include the following compo-
nents mounted on panels within the cabinet:
1- Manually operated motor rated isolating dis-
connect switch, 3 pole, 600 volt.
1- Main line manually operated circuit breaker, 3
pole, 600 volt. The breaker shall permit normal
starting without tripping and shall provide
stalled rotor and short circuit protection per
NFPA 20 requirements.
The isolation disconnect switch and circuit
breaker shall be mechanically interlocked to
assure the circuit breaker "makes" and "breaks"
the load.
1- Primary line contactor that may be manually
operated from the front of the enclosed in
emergencies.
1- Power available signal relay for remote alarm.
1- Auxiliary contact for pump running remote
alarm.
1- Phase failure/reversal monitor to sense loss of
line power, loss of any one phase, phase re-
versal, and undervoltage.
1- Surge suppression on input lines to protect
against voltage transients.
In the rear of the enclosure and accessible from the
back of cabinet, shall be mounted edgewound,
heavy duty speed regulating resistors having con-
tinuous current ratings of 125% of F.L.C., the resis-
tors shall be mounted in racks and insulated from
ground.
The controller shall be one complete unit provided
with solderless connectors at line and load termi-
nals. Size and types of feeder and load cables shall
be as specified in the electrical specifications.
The control panel shall be installed near the fire
pump and motor with access space not less than 30
inches allowed at the rear as per NFPA-20 require-
ments.
