INSTALLATION

Direct and Remote Hard Mount

Direct hard mounting refers to bolting the AD1273 housing
directly to a ceiling. Remote hard mounting involves locating
the housing from a raised ceiling or a building frame through
the use of pipes and flanges (not provided).

Ceiling Preparation

Two circular bolt patterns are located in the roof of the
AD1273 chassis housing (see Figure 12). The outer pattern is
for bolting the chassis housing directly to a ceiling or building
frame (see Figure 13).
NOTES: Inspect the ceiling area around the proposed
installation site looking for wires, pipes, or
obstructions that interfere with the installation.
Inspect the ceiling area around the proposed
!
installation site. The ceiling must be capable of
supporting 19 pounds plus any additional weight
of the installation hardware.

Direct Hard Mount

1) Remove the electric knock-out plug in the center of the
chassis housing roof.
2) Place the chassis housing against the ceiling location and
support it from below. Mark the pre-drilled holes and the
electric knock-out hole on the ceiling.
3) Lower the chassis housing. Drill out the mounting and
electric cable holes in the mounting surface.
4) Tape (preferably) or wire-tie the data, the video, and the
24VAC power wires together into a neat harness with no
kinks or bends.
NOTE: Do not attach the 7-pin Plug connector or the BNC
connector to the harness at this time.
5) Feed the data, the video, and the 24VAC power wiring
harness through the opening in the ceiling or the building
frame, through the electrical knock-out opening, and into
the chassis housing.
6) Bolt the chassis housing to the mounting surface.

Remote Hard Mount

The inner bolt pattern (see Figure 12) attaches a pipe flange to
the chassis housing for remote hard mounting the AD1273 to
different building construction types and/or different height
requirements (see Figure 14).
1) Remove the electrical knock-out plug in the center of the
chassis housing.
2) Place the chassis housing in the desired location and
support from below. Measure and install the support
pipes/flanges between the housing and the intended surface.
3) Tape (preferably) or wire-tie the data, the video, and the
24VAC power wires together into a neat harness with no
kinks or bends.
NOTE: Do not attach the 7-pin Plug connector or the BNC
connector to the harness at this time.
4) Feed the data, the video, and the 24VAC power wiring
harness through the pipe/flange assembly, through the
electrical knock-out opening, and into the chassis housing.
5) Bolt the chassis housing to the mounting surface.
