Wiring NACs and IDCs for Class A

Wire the Style Z (Class A) Notification Appliance Circuits using TB5 of the FACP main circuit
board and TB2 of the N-CAC-5X module. Wire the Style D (Class A) Initiating Device Circuits
using TB4 of the FACP main circuit board and TB1 of the N-CAC-5X. Note that the wiring will be
identical when using TB7 NAC and TB6 IDC of the FACP. Make certain to observe polarity when
connecting the devices to the circuits. The B+ and A+ terminals must comprise the feed and return
for the positive side of a device and the B- and A- terminals must comprise the feed and return for
the negative side of a device. To configure any of the zones for Class B when the N-CAC-5X is
installed, simply wire to the B+ and B- input on the FACP terminal(s) and install the End-of-Line
Resistor after the last device on the circuit. Do not wire to the corresponding A+ and A- terminals
on the N-CAC-5X module.
