the approving authorities as well as NEMA and the
latest edition NFPA 70, National Electrical Code.
Standard Features—The following are included as
standard with each controller:
„ NEMA Type 2 drip-proof enclosure
„ Horsepower rated fusible disconnect switch
with
fuseblock and fuses
„ Horsepower rated motor contactor and overload
relay
„ HAND-OFF-AUTO selector switch

Specifications
Jockey Pump Controllers
The auxiliary jockey pump controller, if required
and specified on the plans and specifications, shall
be factory assembled, wired, and tested and specifically designed for this type of service. This
controller shall be UL listed, and shall be of the
same manufacturer as the main fire pump controller.
The controller shall incorporate a magnetic
starter, control circuit transformer, main disconnect
switch, motor fuse block with fuses, HAND-OFFAUTOMATIC selector switch and a pressure switch.
The pressure switch shall have a range of 15-290
psi (1-20 bars) and have an adjustable differential
range of 15-120 psi (1-8.3 bars). The pressure
switch shall be of the diaphragm type utilizing snapaction type contacts. The pressure switch shall be
mounted inside the controller to prevent any unauthorized adjustment and/or accidental damage. The
pressure switch shall be directly pipe mounted to a
bulkhead pipe coupling without any other supporting members. Field connections shall be made
externally at the controller coupling to prevent distortion of the pressure switch element and mechanism.
The controller shall have a running period timer
to prevent too frequent automatic starting of the
jockey pump motor. The timer shall be set to keep
the motor in operation for at least one minute and
interwired with the pressure switch.
The disconnect switch shall be mechanically
interlocked so that the enclosure door cannot be
opened with the handle in the ON position except by
• FTA500
a hidden tool operated defeater mechanism. The
disconnect switch shall be capable of being padlocked in the OFF position with up to three padlocks
for installation and maintenance safety.
The minimum enclosure rating shall be NEMA
Type 2 (IEC IP11), drip-proof.
All pushbuttons, selector switches, pilot lights
shall be NEMA Type 12, oiltight. Pilot lights (when
specified) shall be transformer type. No pushbuttons
or pilot lights shall be mounted on the enclosure
door.
The control circuit transformer shall be of the
molded winding construction type with built-in
molded terminals and shall be fuse protected. The
fuse shall be built into the transformer.
The controller manufacturer, prior to shipment,
shall hook up and test the jockey pump controller as
a completed assembly. This test shall include, but
not be restricted to, each function the controller
may be required to perform including manual startstop, automatic start-stop and minimum run timing.
The manufacturer shall perform a high potential
test of the controller power circuits at not less than
two times the rated voltage plus 1000 Volts.
The controller shall be a Firetrol brand.
