Section 2: Installation
2.1 Mounting Options
The cabinet may be either semi-flush or surface mounted. The door is removable during the instal-
lation period by opening and lifting it off the hinges. The cabinet mounts using two key slots and
two additional 0.25" diameter holes located in the backbox. The keyslots are located at the top of
the backbox and the two securing holes at the bottom.
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. All wiring should be in accordance with the National and/or Local codes for fire alarm
systems.

former mounting studs. Refer to
