Mount the GC3 Panel’s Backplate
Before mounting the GC3 Panel in its permanent location, use the guidelines below to choose the placement. Also ensure
you have the recommended tools and equipment. See “Recommended Tools and Equipment.”
Choose the Wall Location
To choose a wall location for the GC3 Panel, see “Where to Mount the GC3 Panel.”
Mount the Backplate to a Wall
To mount the backplate to a wall:
1. Position the GC3 Panel at the desired location on the wall.
2. Insert a pencil into the placement feature on the top of the panel and make a mark in the reference groove.
3. Loosen the locking screw on the bottom of the GC3 Panel. This allows the backplate to be removed from the rest
of the chassis.
NOTE:
The locking screw cannot be removed from the panel. Do not use excessive force to remove the captive
screw from the case.

4. Separate the backplate from the GC3 Panel. The backplate hinge is located on the top of the panel. Remove the
bottom of the backplate
fi
rst.
5. Press the backplate
fl
ush against the wall at the mounting location.
NOTE:
The backplate has a built-in level to ensure the GC3 Panel hangs straight.

6. Use the backplate as a template to mark the location of the wiring cutout. Then cut a slot in the dry wall for the AC
power cord and other electrical wiring (if needed).
7. Route the barrel connector for the power supply or 2-conductor
wire (if connecting power to the GC3 Panel’s terminal block) through
the wiring cutout.
8. If you are installing any hardwire loops, an external alarm
sounder, an external in-wall antenna, or open collector outputs that
must be connected to the GC3 Panel’s terminal block, route those
wires through the cutout.
WARNING!!
To avoid serious injury or death while wiring the
terminal block connections, do NOT connect the GC3 Panel’s
power supply to a power source and always ensure that you
disconnect the backup battery before servicing the panel’s
internal components.
9. Attach the backplate to the wall using the four (4) wall anchors
and screws (supplied). The center top screw is the wall tamper and
MUST have an anchor to work.
