2.6.1.2 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 CAC-5X module.  Wire the Style D (Class A) Initiating Device Circuits 
using TB4 of the FACP main circuit board and TB1 of the 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 
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 CAC-5X module.

Ferrite Bead
P/N 29150

Large gauge wire should be looped through 
bead at least once as illustrated.  Smaller 
gauge wire can be looped more often.
