The Honeywell HPFF12(E) and HPFF12CM(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 HPFF12 and HPFF12CM connect to any 12 or 24V Fire Alarm Control Panel (FACP) or operate stand-alone. They provide regulated and filtered 24VDC power to four NAC's and an auxiliary output. The NAC outputs are rated at 3.0A each and the auxiliary output is rated at 2.0A (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 12.0A. Main Features Four (4) power limited supervised notification application circuits (NAC's) capable of supplying +24VDC at 3.0A maximum each. Supervised AC input, battery voltage, auxiliary output, charger, and earth ground faults Trouble indication for supervision Optional two-hour delay for AC loss Separate Trouble and AC Fail Form-C relay contacts. The Trouble Form-C relay contacts selectable for immediate or a 2 hour delay with AC failure. NAC Overload protection and indication.
