Honeywell  HPFF12  and  HPFF12CM(E)  are  Notifica-tion   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  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 there-fore must be taken into account for power supply loading and battery size calculations). The combined output cannot exceed 12.0 amps.

The HPFF12 and HPFF12CM provide independent output cir- cuit 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 diagnos-tics. Synchronization is built in for five appliance brands.
The  HPFF12  and  HPFF12CM  have  two  fully  independent supervised initiating circuits that can be used for synchronized strobes  and  coded  horns.  Their  NAC  outputs  may  be  config-ured 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

These  power  supplies  contain  an  internal  Battery  charger
capable of charging up to 26.0 amp-hour (AH) batteries.
The  HPFF12  is  mounted  in  a  lockable  wall  cabinet  that  can
accommodate  up  to  two  18AH  batteries.  The  HPFF12CM  is
designed  to  mount  in  Honeywell’s  large  equipment  enclosure
(EQBB-D4;  order  separately).    Up  to  three  HPFF12CM  sup-
plies can be mounted in a D-sized EQ cabinet in positions 2, 3,
and 4. Each HPFF12CM can accommodate two 12AH batter-ies.

One of the most challenging aspects of a retrofit application is
locating the existing End-of-Line (EOL) resistor. In these appli-
cations  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. This fea-
ture  speeds  installation  and  system  checkout  because  the
actual  EOL  does  not  need  to  be  located  and  changed  in  the
circuit. The reference resistor must be within the range of 1.9k to 25k.

4 separate programming resistors for the HPFF12 are pro-
vided  in  the  hardware  kit  shipped  with  each  HPFF12(E)  and
HPFF12CM(E).  They are 3.9K (5 of these are provided, need only
1 for programming), 2.2K (1 each), 4.7K (1 each) and 10K (1 each)
