2.1.2 Mounting the Cabinet
Carefully unpack the system and check for shipping damage. Mount the cabinet in a clean, dry,
vibration-free area where extreme temperatures are not encountered. The area should be readily
accessible with sufficient room to easily install and maintain the panel. Locate the top of the cabi-
net approximately five feet above the floor with the hinge mounting on the left. Determine the
number of conductors required for the devices to be installed. Sufficient knockouts are provided
for wiring convenience. Select the appropriate knockout(s) and pull the required conductors into
the box. Note that knockouts are also located on the back of the cabinet. All wiring should be in
accordance with the National and/or Local codes for fire alarm systems.
The cabinet can be surface or flush-mounted. For flush-mount installation of the cabinet, the hole
for the enclosure should be 14.5" W x 24.75" H x 3.438" D (36.8cm W x 62.9cm H x 8.73cm D).
Do not flush-mount in a wall designated as a fire break. The outside dimensions of the cabinet are
16" W x 26.25" H x 4.125" D (40.64cm W x 66.68cm H x 10.48cm D).
Follow these steps to properly mount the cabinet.
1. Mark and predrill holes for the top two backbox keyhole mounting bolts using the dimensions
shown.
2. Install two upper fasteners in the wall with the screw heads protruding.
3. Using the upper 'keyholes', mount the backbox over the two screws.
4. Mark and drill the lower two holes.
5. Install the remaining fasteners and tighten all fasteners to complete backbox mounting.
