Main Fire Alarm Module Terminal Connections
Wire devices to terminals as shown in Figure 11 below. See Wiring Tables on page 20 for wiring instructions, Appendix A on
page 33 for compatible devices, and Appendix C on page 37 for specifi cations.
Do not exceed power supply ratings:
PFC-5002, PFC-5004, total current for NAC circuits is
2A max.
PFC-5004E/PFC-5008, total current for NAC circuits is 5A
max.

WIRING
When wiring devices, please keep in mind the following:
All terminals are shown from the back of the main fi re alarm board assembly (pointing towards the rear of the enclosure).
•
All power limited circuits must use type FPL, FPLR, or FPLP power limited cable.
•
Initiating circuits are fully supervised and rated for 26 VDC, 3 ma standby, 2.2 Vp-p ripple, 50 mA max. alarm. They may
•
be confi gured as required. Maximum loop resistance is 100 ohms, 50 ohms per side.
NAC circuits are fully supervised and rated for 24 FWR 1.7 amp max. each. They must be wired as shown in the wiring
•
tables on page 20.
On the PFC-5004 & PFC-5004E/PFC-5008, the auxiliary common supervisory relay contacts will act as a second set of
•
common alarm contacts if there are no initiating circuits set as supervisory.
Initiating circuits must be all either Style B or D. If Style D is selected, cut the number of circuits in half.
•
