Nac Circuit Wiring; 1: Class B; 2: Znac-Ps Class A Option Module - Honeywell HPF-PS6 Instruction Manual

Installation

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 manufac-
turer.
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 HPF-PS6 or HPF-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.
ZNAC-PS SW1 and SW2 settings must match the HPF-PS output 1 and 2 settings to ensure proper supervision.
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 sup-
port 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.
NOTE: Class A supervision and the ZNAC-PS module are not intended for use with door holder operation.
