Note: Unit is equipped with one (1) 1A max. auxiliary output (0.45A for Canadian applications): “AUX”
NAC outputs programmed for “AUX” with battery backup will remain battery backed up during power
outage. For loads connected to “AUX” please, refer to battery “Stand-by Specifications” above for ratings.
When loads are connected to the “AUX” output during alarm condition, and total current from AUX and
remaining outputs may not exceed total alarm current for the particular FireSwitch model. AUX outputs
are not supervised.
To provide supervision use a UL Listed end of line relay or similar method.
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code NFPA 70/NFPA 72/ANSI/Canadian
Electrical Code/CAN/ULC-S524/ULC-S527/ULC-S537, Signaling Code and with all local codes and authorities
having jurisdiction .
PRODUCT IS INTENDED FOR INDOOR DRY USE ONLY.

(pg. 11)
1 . Mount the unit in desired location . Mark and predrill holes in the
wall to line up with the top two keyholes in the enclosure . Install two
upper fasteners and screws in the wall with the screw heads protruding .
Place the enclosure’s upper keyholes over the two upper screws; level and secure .
Mark the position of the lower two holes . Remove the enclosure . Drill the lower holes
and install the two fasteners . Place the enclosure’s upper keyholes over the two upper screws . Install the
two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 24) .
Secure enclosure to earth ground (Fig. 1, pg. 4) .
Small terminal block wire gauges range from 16 AWG to 22 AWG, all others range from 12 to 22 AWG .
2 . Connect the line [L] and neutral [N] terminals to a separate unswitched 20A protected branch circuit
(120VAC, 60Hz) dedicated to the Fire Alarm System . Connect ground to the ground lug (Fig. 1, pg. 4).
Use 12 AWG wire .
