3 Enclosure Installation and Inner Door Assembly
The AX-CTL-1L, AX-CTL-2 and AX-CTL-4 Intelligent Fire Alarm Control Panels are delivered fully assembled.
Carefully unpack the system and check for shipping damage. Remove all circuit boards and 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
5½ feet (1.7 m) above the floor with the hinge mounting on the left. Determine the number of conductors required
for the devices and circuits to be installed. Sufficient knockouts are provided for wiring convenience in both the top
and side walls of the back box. Select the appropriate knockout(s) and pull the required conductors into the back
box, separating power limited from non-power limited conductors – refer to the recommended cable routing diagram
Section 5. All wiring should be in accordance with National Electric Code (NEC), State and Local codes.

Note: The back box includes seven single knockouts (7/8”), and seven double knocks (7/8” or 1
¾”) two located on the bottom of the back box. Care should be taken when utilizing the inner 7/8”
knockout of the 1 ¾” knockout to avoid knocking out the 1 ¾”.
For surface mounting there are five pre-drilled holes located on the rear of the back box (see figure 1).
The top center mounting hole is keyed for ease of mounting.
Place the back box on the wall and mark the top keyed mounting hole.
Drill the marked location and partially install the mounting screw in the wall.
Hang the cabinet on the mounting screw.
Level the cabinet and mark the remaining holes and then drill the holes.
Insert all screws and firmly tighten.
For semi flush mounting, in addition to the rear mounting holes, 1/8” knockouts are located on the sides
and top of the back box for securing the enclosure to the wall studs.
