manual abstract
It uses only 2" (5 cm) between the projector and the ceiling to conveniently and securely enclose the products out of sight above the display device. • PMP Series Projector Mounting Poles — Available in fixed lengths of 4" (10 cm), 6" (15 cm), 10" (25 cm), and 12" (30 cm), PMP Projector Mounting Poles are used with the PCM 240 and UPB 25 to create individualized installations. Each pole includes a cutout, which provides convenient cable access. • UPB 25 Universal Projector Mounting Bracket — The Extron UPB 25 universal projector mount is compatible with nearly every projector having a weight of up to 25 pounds (11 kg). It features independent adjustment of roll (±4 degrees of horizontal tilt), pitch (±25 degrees of vertical angle) and yaw (360 degrees of rotation on a pole mount, or 10 degrees when mounted flush to the ceiling) for precise control of each axis and exact alignment of the projector. Locking mechanisms maintain the original positioning settings when servicing requires the projector and attached arm assembly to be removed from the mounting assembly. 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, . 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.

Preparing the ceiling W The PCM 240 must not be supported by the suspended ceiling itself. It must be secured to and suspended from the structural ceiling above. W Check the structural ceiling to ensure that it can handle a load four times the weight of the final setup. N Refer to local building standards and codes to verify that the installation will meet all the regulatory requirements. Identify the location for projector placement. Remove the ceiling tiles adjacent to the tile where the projector will be mounted. This will allow easy and safe access while installing the projector mount. Inspect the structural ceiling where the projector mount will be installed to ensure there are no cracks or weaknesses that could jeopardize the completed installation. Select the correct installation hardware from those supplied. Hardware for each of three methods of hanging and securing the PCM 240 is supplied: • Turnbuckles and tie wire tied to concrete anchors for concrete structures • Turnbuckles and tie wire tied to eye screws for joists • Turnbuckles and tie wire wrapped around wooden trusses. Alternatively, threaded rods (not supplied) may be used to secure the mount to the ceiling structure. Safety cable is provided to hold the mount up in the event that any tie wire or rods become loose or detached as a result of an earthquake or accident. Installing the projector ceiling mount 1.
