Honeywell HPFF8 User Manual

40 HPFF8(E)/HPFF8CM(E) NAC Expander — P/N 53499:B4 10/1/2018
Applications Connecting Multiple Units
Notes for Figures 5.5–5.10:
1. The FACP’s NAC output must be regulated (not Full Wave Rectified [FWR]) if the HPFF8 is programmed for Sync Generator.
2. The number of possible units that can be interconnected depends on the current capability of the FACP output. Each HPFF8 input
draws 12.26 mA at 24 VDC.
3. The total line impedance for interconnected units cannot be such that it creates a voltage drop > 2 VDC.
Zline total =2V/(1 Unit + 1 ELR)
Example: Zline total = 2V/(12.26 mA + (24-2)/4.7K) =118.1 ohms
