PCM 240 • Installation Guide
The Extron PCM 240 Drop Ceiling Projector Mount is used for hanging
PoleVault®System AV products and various projectors.
The PCM is installed above the drop ceiling and secures the adjustable
pipe in a pass-through pipe adapter plate. The pipe then supports the
mounting of the Extron PMK 550 and UPB 25 projector bracket.
The key components of the PCM 240 are shown in figure 1.
Also included in the kit are:
4 turnbuckles, 5 lag eye bolts, 5 concrete anchors, 2 cable clamps,
1 safety wire – 15 feet, 2 tie wires – 30 feet, 4 T-frame screws, 4
adhesive pads, escutcheon ring.
IMPORTANT SAFETY INSTRUCTIONS
Read all instructions before starting installation.
When using this accessory, basic precautions should always be followed, including the following:
WARNING: Risk of Personal Injury. Maximum setup load for the PCM is 50 lbs (22.7 kg).
SAVE THESE INSTRUCTIONS
NOTE: Refer to local building standards and codes to verify that the installation will meet the regulatory requirements.
Observe all local and national building and safety codes, UL requirements, and ADA accessibility guidelines.
WARNING: Risk of Personal Injury and property damage. Do not exceed specified weight limits of any component of
the installation. Follow the manufacturer's specifications and installation instructions.

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.
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).
TIP: Mark the screen direction on the back of the tile to
help with orientation of the tile when replacing it after
cutting�
c. Place the PCM base plate over the T-frame, between the two marks.
Lightly tighten the T-frame securing screws.
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. Using these dimensions, mark and cut a hole (using a 2 inch hole saw) for
the projector pipe in the removed ceiling tile (see figure 3).
g. If required, to prepare the ceiling tile for a power outlet, use the PCM
plate to trace and cut out the 2-gang hole in the ceiling tile for a
UL approved RACO®junction box.
If this is not required, proceed to step 3.
Step 2 — Install the Electrical Box.
The following method is recommended for integrating a RACO electrical box
(not supplied) on the PCM base plate. A RACO box (#8471), an MK box, or
standard UL electrical boxes can be inserted. Mounting holes for Extron
3 inch deep, ¼ rack wide devices are also included.
Install the RACO box on the PCM plate as follows:
a. Attach the box to the plate, using the smallest notches in opposite corners
of the cut-out. Do not tighten the screws fully at this time.
b. On the room side of the tile, slide the plaster ring under the screws.
c. Fully tighten the screws
WARNING: Risk of Personal Injury. For safety, complete all wiring
of the electrical boxes and accessories after the plate
is installed and secure.
All electrical installation should be done by a qualified
electrician.
Step 3 — Secure the PCM Base Plate to the Ceiling.
Tie wire installation
a. Replace the cut ceiling tile, checking the orientation.
b. Replace the PCM base plate over the ceiling tile and align the hole with
the PCM adapter plate.
c. Attach the four turnbuckles to the mounting plate, one at each corner.
ATTENTION: Risk of Personal Injury and property damage.
• DO NOT rest or lean on the mounting plate or
suspended ceiling when attaching the turnbuckles
and tie wire, or when drilling into the ceiling.
• For safest installation, insert the turnbuckle from
the outside so that it hooks inwards.
d. Mark and drill four holes, approximately 1¼ inch (32 mm) deep into the
ceiling joists, using a 1/4 inch (6.4 mm) diameter drill bit. Do this at 10
degrees out from vertical. Drill a fifth hole centered above the PCM for
the safety cable (see figure 5). Minimum suitable joist size should be
2 inches by 4 inches.
e. Install appropriate anchors or lag eye bolts for the structural ceiling into
each drilled hole.
Attach turnbuckles
to long sides.

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.
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.
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.
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.
