Pre-Installation  
Determine the exact location of the installation on the drop ceiling.  
Consider the following:  
The vertical and horizontal offsets of the projector from the proposed  
location.  
The projector dimensions relative to the image target.  
NOTE: See the projector manual for details.  
Installation  
Step 1 — Mark the Frame and Cut the Ceiling Tile.  
Figure 1. PCM 240 Parts  
a. At the location for the projector, identify the ceiling tile and T-frame  
where the PCM will be installed.  
b. Remove the predetermined ceiling tile and mark the maximum and  
minimum throw distances of the projector on the T-frame (see  
figure 2).

d. Mark the location of the PCM base plate on the T-frame to aid in  
replacing it in the correct location.  
e. Measure the distances X and Y (see figure 2) from the inner vertical  
section of the front and left T-frame runners to the center of the  
Pipe Adapter Plate.

f. Loop the safety cable through the center anchor or lag eye bolt,  
attach it to the plate center holes (figure 6) and secure it with the  
cable clamps.  
Secure PCM to frame  
(from either side)

g. Cut appropriate lengths of the supplied tie wire.  
Loop the wire through the anchors or lag eye bolts and the  
turnbuckles, then twist the wire around itself at least five times.  
T-frame  
h. Tighten the turnbuckles by hand (see figure 6), and level the plate  
so that it just rests on the grid.  
ATTENTION: Potential Damage to Property.  
• The four hanging wires should be taut, taking  
the full weight of the completed installation.  
• Overtightening the turnbuckles could cause  
the T-bar assembly to be lifted, making the  
suspended ceiling bowed and unsafe.  
Adjust the turnbuckles to take  
up any slack in the hanging wire.  
Figure 6. Adjust the Turnbuckles.  
j.  
Tighten the four T-frame securing screws on the PCM.  
Step 4 — Final Installation.  
The PCM 240 comes with a threaded pipe adapter installed in the adapter  
plate. This allows for an Extron PMP projector mounting pole to be fitted.  
To fit the mounting pole, do the following:  
a. Back out the set screws on the pipe adapter/adapter plate assembly.  
b. Screw the pole into the adapter. A minimum of three full turns is  
required to safely secure the pole in place  
c. Secure the pole in place by tightening down the set screw on the  
pipe adapter/adapter plate assembly. Cabling for the projector can  
be accessed through the cut-out in the PMP pole.  
d. Other optional accessories can also be installed at this point. These  
include the Extron PMK 350, a low profile, two product mounting  
kit, and the UPB 25, a Universal Projector Mounting Bracket suitable  
for most projectors weighing up to 25 pounds.  
e. Complete any further device installation according to the relevant  
device manual.
