2.2 NAC Circuit Wiring
2.2.1 Class B
The standard configuration for NACs is Class B as shown below. Use Listed ELRs supplied by the FACP or compatible equipment man-
ufacturer.
2.2.2 ZNAC-PS Class A Option Module
The ZNAC-PS is an optional Class A conversion module which mounts to connector J8 on the upper right side of the circuit board. This
module allows the FL-PS6 or FL-PS10 to support Class A Notification Appliance Circuits on all outputs. Class A
power
supervision is
also supported on output circuits #1 and #2 when either of these outputs are configured as resettable or non-resettable Auxiliary power.
Two slide switches are located on the right side of the ZNAC-PS module to properly configure output circuits #1 and #2 for either NAC
or Auxiliary Power operation, as described below. Note that there are no slide switches for the remaining outputs as these outputs do not
support Class A power supervision.
•
For output #1, set the upper switch to either “NAC1” or “AUX1” depending on the intended operation.
•
For output #2, set the lower switch to either “NAC2” or “AUX2” depending on the intended operation.
