The Honeywell Power Products FireForce (HPFF) is one of the most innovative fire alarm remote power supplies available that com-
plies with UL 864 9th Edition. Designed with advanced switch-mode power supply technology and built with the latest surface-mount
electronic manufacturing techniques, they incorporate several new features that demanding installers requested to speed them through
installation and servicing.
The HPFF12 is a 12.0 A power supply that provides power for Notification Appliance Circuit (NAC) expansion to support ADA require-
ments and strobe synchronization (sync). It provides filtered 24 VDC power to drive four NAC outputs. The four-output circuits may be
configured as: four Class B (Style Y); two Class A (Style Z); two Class B and one Class A; or four Class A with the optional HPP31076
Class A adapter installed. The input circuits, which control the power supply operation, are triggered by the reverse polarity of a NAC or
by the reverse polarity of a 12 VDC or 24 VDC power source. The power supply is compatible with 12 VDC or 24 VDC control panels.
It contains an internal battery charger capable of charging up to 26.0 AH (amp hour) batteries.
The HPFF12 is a wall cabinet unit that can accommodate up to two 18 AH batteries. It can be configured to internally house one address-
able control or relay module, a six-circuit relay module, or a six-circuit control module. (Modules available through authorized Honey-
well Fire Systems distributors.)
HPFF12CM is a chassis-mount model that can fit two 12.0 AH batteries. It is used for a multi-pack option that allows up to three
HPFF12CM units to be mounted in a compatible Fire Alarm Control Panel (FACP) cabinet; these separately sold cabinets are also
referred to as the large equipment enclosure. The addressable control or relay module option is not available on these models. (Equip-
ment enclosures available through authorized Honeywell Fire Systems distributors.)
HPFF12 and HPFF12CM power supply models operate at 120 VAC/60 Hz.
HPFF12E and HPFF12CME power supply models are export units that operate at 240 VAC/50 Hz.
NOTE: When an HPFF12CM unit is mounted in a FACP cabinet, the top row must be left open for proper heat dissipation.
1.1 General
The HPFF power supplies are used as remotely mounted power supplies and battery chargers. The Fire Alarm Control Panel (FACP) or
initiating device is connected to the input circuit(s). When the control input circuit activates due to the reverse polarity of the signal from
the initiating device, the power supply will activate its NAC outputs.
During the inactive or non-alarm state, the power supply supervises its NAC field wiring independently for short and open conditions. If
a NAC fault is detected, the power supply will open the initiating device input signal to notify the FACP and the Normally-Closed Trou-
ble contact. If an AC loss is detected, the power supply will open the initiating device input signal, Normally-Closed Trouble, and a ded-
icated AC Fail contact.
If an alarm condition occurs and the NAC outputs are activated, the supervision and charger are disabled and the NAC circuit is no lon-
ger supervised (except for excessive loading or shorts). Supervision of other power supply faults such as battery voltage, AC loss, and
ground fault will continue and may be monitored via Trouble contacts.
1.2 Features
•
The enclosures offered are self-contained lockable cabinets
– If the local Authority Having Jurisdiction (AHJ) requires the fire protection system to have matching locks, the units' locks may
be swapped in the field to accommodate Honeywell Fire Systems branded panels: Honeywell, Notifier, Gamewell-FCI, Silent
Knight, Farenhyt, and Fire-Lite Alarms
