(item 2) as shown. Do not over-tighten nuts.
The GEMC-24VR allows one of the four NAC outputs to be
a "regulated" 24V output supplying a constant voltage to
Listed 24V Accessories as per the UL Standard for Safety
for Control Units and Accessories for Fire Alarm Systems
(UL 864). Secure the GEMC-24VR printed circuit board to
the HW1489 battery "Shelf" as follows:
1. Insert four SC631 screws (item 5) such that the
threads protrude from the bottom of the HW1489
battery Shelf (item 6) as shown. Secure the screws
The images below show the installation instructions for the smaller enclosure (model GEMC-NAC7S); the larger enclosure
diagrams are similar, except the larger enclosure (model GEMC-NAC7L) includes an additional battery shelf and tamper
switches.
