Connecting Multiple Units - Honeywell HPFF8 Instruction Manual

Connecting Multiple Units

5.4 Connecting Multiple Units
Two or more HPFF8s can be connected to each other to provide additional NAC extenders for a system; see wiring in Figures 5.5–5.10.
Maintain separation of power-limited and nonpower-limited wiring as discussed in Section 2.6 on page 24.
NOTE: Multiple units should not be connected in a "daisy chain" fashion. DO NOT connect a NAC output of one unit to the initiating device
signal input of the next unit. The synchronization signal will not pass unimpeded through multiple units with this wiring method.
