Fire Pump Controllers for
Business-Critical Continuity
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 15290 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.

Emerson Network Power.
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 tri-axial 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 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.
