Section 1: System Overview

The Honeywell Power Products FireForce (HPFF) is one of the most innovative fire alarm remote

power supplies available that complies 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 requirements 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 addressable control or relay module, a six-circuit relay module,

or a six-circuit control module.

(Modules available through authorized Honeywell 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.

(

Equipment 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.

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 Trouble contact. If an

AC loss is detected, the power supply will open the initiating device input signal, Normally-Closed

Trouble, and a dedicated 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 longer 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.

NOTE:

When an HPFF12CM unit is mounted in a FACP cabinet, the top row must be left open

for proper heat dissipation.
