The Honeywell HPFF8(E) and HPFF8CM(E) are Notification Appliance Circuit (NAC) Expander Power Supplies designed to extend the power capabilities of existing NACs and provide power for auxiliary devices. The HPFF8 and HPFF8CM connects to any 12 or 24V Fire Alarm Control Panel (FACP) or operates stand-alone. They provide regulated and filtered 24VDC power to four NAC's 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 8.0 amps. The HPFF8 and HPFF8CM provide independent output circuit supervision so in the event of a 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 HPFF8 and HPFF8CM have two fully independent supervised initiating circuits that can be used for synchronized strobes and coded horns. Their 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 Specifications HPFF8CM: 8.0A fire rated power supply (chassis mounted).
