CHAPTER 2
: Installation
2.1 Mounting Options
The cabinet may be either semi-flush or surface mounted. The door
is attached to the cabinet by two hinges. The cabinet mounts using
two key slots and one additional 0.250" (6.35 mm) diameter holes
located in the backbox. The key slots are located at the top of the
backbox and the one 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 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. 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.
