HPFF12 Power Supply

HPFF12 is a Notification Appliance Circuit (NAC) Expander Power Supply designed to extend the power capabilities of existing NACs and provide power to auxiliary devices. The HPFF12 connects to any 12V Fire Alarm Control Panel (FACP) or operates stand-alone.
They provide regulated and filtered 24 VDC power to four NACs and one auxiliary output. The NAC outputs are rated for 3.0 amps each and the auxiliary output is rated for 2.0 amps (this output is supplied continuously, even in alarm, and therefore must be accounted for in power supply loading and battery sizing calculations). The combined output cannot exceed 12.0 amps.
HPFF12s provide independent output circuit supervision, so in the event of a NAC failure they can notify the attached FACP. Additionally, they have a memory function that displays past problems (per NAC) for quick diagnosis.

HPFF12 : 12.0 A fire rated power supply. Unit includes case, battery cable and installation instructions. 120VAC/60Hz.
