Section 3: Installation
3.1 Mounting Options
The cabinet may be surface mounted. The door is
removable during the installation period by opening and
lifting it 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. 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 right. 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.
3.2 Backbox Installation
Surface Mounting
1. Open the door and lift the door off the pin hinges.
2. Remove the main circuit board and transformer from the backbox before installation. Set the
board and transformers aside in a safe, clean place. Avoid static discharge which may damage
static sensitive components on the board.
3. Mark and predrill holes for the top two backbox keyhole mounting bolts using the dimensions
shown.
4. Install two upper fasteners in the wall with the screw heads protruding.
5. Using the upper 'keyholes', mount the backbox over the two screws.
6. Mark and drill the lower two holes.
7. Install the remaining fasteners and tighten all fasteners to complete backbox mounting.
8. Carefully reinstall the main circuit board and transformer, using appropriate precautions to
prevent damage to components due to static discharge.
