HPFF8CM Fire Alarm Power Supply

The Honeywell HPFF8 and HPFF12 Series are Notification Appliance Circuit (NAC) Expander Power Supplies extend the power capabilities of existing NACs and provide power for auxiliary devices. They connect to any 12 or 24V Fire Alarm Control Panel (FACP).

They provide regulated and filtered 24VDC power to four NAC's and an auxillary output. The NAC outputs are rated at 3.0 amps each and the auxillary output is rated at 2.0 amps. These units have a trouble memory feature that displays past troubles (by NAC) for rapid diagnostics. Synchronization is built in for five appliance brands.

The wall mount units can accommodate up to two 18AH batteries. The CM versions mount in Honeywell's large equipment enclosure. Up to three HPFF12CM supplies can be mounted in an EQBB-D4 (4 HPFF8CM's).

In applications that have EOL values other than the 3.9k normally used with the HPFF12, a single resistor matching the existing EOL can be used as a reference for all the outputs, thus speeding up installation.
