Honeywell HPFF8, HPFF8CM, HPFF8E, HPFF8CME NAC Expander/Power Supply Description 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 con- nects 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 HPFF8 3.0 amps each and the auxiliary output is rated at 2.0 amps (this output is continuously supplied, even in alarm,and there- a fore 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 0' supervision so in the event of a NAC fault they can notify the attached FACP. In addition they have a trouble memory fea- r ture that displays past troubles(by NAC)for rapid diagnostics. 01 Synchronization is built in for five appliance brands. The HPFF8 and HPFF8CM have two fully independent super- vised initiating circuits that can be used for synchronized strobes and coded horns. Their NAC outputs may be config- ured as any of the following: \ HPFF8CM • four Class B(Style Y) • two Class A(Style Z) —Two Class B&one Class A. • two Class B and one Class A —Two Class A(Style Z). • four Class A with the optional HPP31076 Class A adapter —Four Class A(requires the HPP31076 Class A adapter).
