Jockey Pump Controllers
Specifications
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
snap-action 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 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.
Fire Pump Controllers for
Business-Critical Continuity
The minimum enclosure rating shall be NEMA
Type 2 (IEC IP11), drip-proof.
The controller shall be certified to meet or exceed
the requirements of the 2006 International Building Code and the 2007 California Building Code
for Importance Factor 1.5 Electrical Equipment for
Sds equal to 1.88 or less severe seismic regions.
Qualifications shall be based upon successful triaxial shake-table testing in accordance with ICC-ES
AC-156. Certification without testing shall be unacceptable. Controller shall be clearly labeled as rated
for installation in seismic areas and a Certificate of
Conformance as well as a Center of Gravity drawing
shall be provided with the controller.
All push-buttons, selector switches, pilot lights
shall be NEMA Type 12, oiltight. Pilot lights (when
specified) shall be transformer type. No push buttons 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
start-stop, 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.
