Section 2: Installation
The cabinet can be surface mounted or semi-flush mounted using the optional Trim Ring P/N:
TR-1-R. The door is removable during the installation period by opening and lifting if off the
hinges. The cabinet mounts using two key slots at the top of the backbox and two additional 0.250”
diameter holes located at the bottom.
Carefully unpack the system and check for shipping damage. Select a location for the cabinet that
is 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 control panel.
Locate the top of the cabinet 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 and determine the
appropriate knockouts. All wiring must be in accordance with the National and/or Local codes for
fire alarm systems and power supplies.

5. Mount the backbox, install the remaining fasteners and tighten all screws.
