8 HPFF8(E)/HPFF8CM(E) NAC Expander — P/N 53499:B4 10/1/2018
Section 1: System Overview
The Honeywell Power Products FireForce 8 (HPFF8) 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, it incorporates several new features that demanding installers requested to speed them through
installation and servicing.
The HPFF8 is an 8.0 A power supply for Notification Appliance Circuit (NAC) expansion to support ADA requirements and strobe syn-
chronization (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 supplies are compatible with 12 VDC or 24 VDC control panels. They con-
tain an internal battery charger capable of charging up to 26.0 AH (amp hour) batteries.
The HPFF8 models are wall cabinet units that can accommodate up to two 18 AH batteries. They can be configured to internally house
one addressable control or relay module, a six-circuit relay module, or a six-circuit control module. (Modules are available through
authorized Honeywell Fire Systems distributors.)
The HPFF8CM is a chassis-mount model that can fit two 12.0 AH batteries. It is a multi-pack option that allows up to four CM 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. (Equipment enclosures are available through authorized Honeywell Fire Systems distributors.)
The HPFF8 and HPFF8CM power supply models operate at 120 VAC/60 Hz.
The HPFF8E and HPFF8CME power supply models are export units that operate at 240 VAC/50 Hz.
1.1 General
The HPFF8 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.
