The Honeywell HPFF12 Notification Appliance Circuit (NAC) Expander Power Supplies designed to extend the power capabilities of existing NACs and provide power for auxiliary devices. The HPFF12 connects to any 12 or 24V Fire Alarm Control Panel (FACP) or stand alone panel. It is available in 12.0 amps and provides regulated and filtered 24VDC power to four NA Cs and an auxiliary output.The NAC outputs are rated at 3.0 amps each and the auxiliary output is rated at 2.0 amps (this output is continuously supplied, even in alarm, and therefore must be taken into account for power supply loading and battery size calculations). The combined output cannot exceed 12.0 amps.The HPFF12 provide independent output circuit supervision so that in the event of an NAC fault they can notify the attached FACP. In addition, they have a trouble memory
feature that displays past troubles (by NAC) for rapid diagnostics. Synchronization is built-in for five appliance brands. The HPFF12 has two fully independent supervised initiating circuits that can be used for synchronized strobes
and coded horns.The NAC outputs may be configured as any of the following:
• four Class B (Style Y)
• two Class A (Style Z)
• two Class B and one Class A
• four Class A with the optional HPP31076 Class A adapter
These power supplies contain an internal Battery charger
capable of charging up to 26.0 amp-hour (AH) batteries.
The HPFF12 is mounted in a lockable wall cabinet that can
accommodate up to two 18AH batteries. The HPFF12CM is
designed to mount in Honeywell’s large equipment enclosure
(EQBB-D4; order separately). Up to three HPFF12CM sup-
plies can be mounted in a D-sized EQ cabinet in positions 2, 3,
and 4. Each HPFF12CM can accommodate two 12AH batteries.
