About this Manual
This manual discusses how to safely install and use the Extron PCM 240 Projector Ceiling Mount.
About the PCM 240 projector ceiling mount
The Extron PCM 240 Projector Ceiling Mount is a versatile ceiling plate for installation in classrooms or boardrooms with 2' x 2' or 2' x 4' T-bar style suspended ceiling. The PCM 240 should be secured to the structural ceiling, above the suspended ceiling tiles, using turnbuckles and tie wire. Once secured in place, it is easily fixed to the suspended ceiling T-bar with the supplied screws. When properly installed, it can hold up to 50 pounds (23 kgs) of A/V equipment. The projector mounting pole is easily installed in the threaded pipe adapter mounted on a sliding plate, allowing horizontal adjustment for correct alignment. The PCM 240 includes mounting holes for Extron 3" deep, ¼ rack wide devices (e.g. MPA 122), and has two openings for Raco (catalog #8471) or UL junction box insertion, providing integral power access points, video connection, or simple cable pass-throughs.
Figure 1 — Typical application of PCM 240

Attach Washer and Nut and Secure
Attach safety cable to center holes and secure with cable clamps.

Attaching the tie wire

1. Cut four equal lengths of wire, sufficient to be terminated
at both ends (at ceiling and turnbuckles) with at least five loops around itself.
2. Loop the wire through the anchors, eye screws, or over the
truss, and twist the wire around itself at least five times.
Figure 6 — Anchor and screw tie wire fastening
N The final loop should be tightly bent and secured to the
wire to avoid untwisting under stress.
3. Loop the wire through the turnbuckles, twisting the wire
around itself at least five times to secure it.
4. Using a wrench, adjust the turnbuckles to take up slack,
and to level the ceiling plate so it just rests on the grid. The four support wires should be taut, and should take the full weight of the completed installation.
5. Tighten the T-bar securing screws fully.

Attaching the safety cable

As an added precaution, the supplied safety cable must be installed. This will help hold the mount up in the event that any of the tie wires, or threaded rods come loose or detach during an earthquake or accident.
To install the safety cable, follow the steps below:
1. When the projector ceiling mounting plate is attached to
the structural ceiling and rests on the T-bar, find and mark a point directly above the plate’s center.
C DO NOT rest, or lean on the plate or suspended
ceiling grid during installation of safety cable, or during installation and wiring of electrical boxes, accessories and projector.
2. At the marked location, drill a hole and install a ceiling
anchor or eye screw, following the steps in “Securing the mounting plate to the structural ceiling” on page 6.
3. Pass the safety cable through the anchor and attach it with
even lengths to the center holes on either side of the plate. Secure using the cable clamps.

Threaded rod installation

If threaded rods (not supplied) are to be used instead of the supplied tie wire to secure the plate to the ceiling, insert the threaded rods through the holes at the ends of plate. Secure with washers and nuts. Adjust the length as needed to ensure the plate remains level and so it just rests on the T-bar. The rods should take the full weight of the completed installation.
