Honeywell HPFF12 Power Supply (New w/Cab)

Honeywell HPFF12. New with metal box/cabinet.

This Honeywell Power Supply is a Notification Appliance Circuit (NAC) Expander Power Supplies. Designed to extend the power capabilities of existing NACs and provide power for auxiliary devices. Connects to any 12 or 24V Fire Alarm Control

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. The auxiliary output is rated at 2.0 amps. This output is continuously supplied, even in alarm. And must be taken into account for power supply loading and battery size calculations. The combined output cannot exceed 12.0 amps.
Provide independent output circuit supervision in the event of a NAC fault they can notify the attached FACP. They have a trouble memory feature that displays past troubles (by NAC) for rapid diagnostics. Synchronization i s built in for five appliance brands.

These power supplies contain an internal Battery charger capable of charging up to 26.0 amp-hour (AH) batteries. The Power Supply is mounted in a lockable wall cabinet that can accommodate up to two 18AH batteries. One of the most challenging aspects of a retrofit application is locating the existing End-of-Line (EOL) resistor. EOL can b e used as a reference for all the outputs. This feature speeds up installation and system checkout. Because the actual EOL does not need to b e located and changed in the circuit. The reference resistor must b e within the range of 1.9k to 25k.
