Extron electronic 305SA manual Cut the Ceiling Tile, Preliminary Safety Hardware Installation

4.— Cut the Ceiling Tile

a. Mark the location of the PCM 340 on the

T-frame. This aids putting it back in the correct

location when the tile is replaced.

TIP: Mark the screen direction on back

of the tile (for example with an arrow or

“to front”) to help orientation of tile when

replacing it after cutting

b. Measure the distances X and Y (see the figure

at right) from the inner vertical section of the

front and left T-frame runners to the center of

the Pipe Adapter Plate.

Using the X and Y dimensions, mark and cut a

hole for the slotted pipe in the ceiling tile.

TIP: Place the tile on a box and mark the

center of the hole on the underside of the

tile. Use a hole saw bit to start to cut the

hole by hand (turning bit counter clock-

wise) to avoid damaging the tile. When the

drill bit is through the tile, turn the tile over

and finish cutting from the top side
