SUSPENDED CEILING INSTALLATION
1 PREPARE CEILING TILE
Remove the ceiling tile from the ceiling. Insert the compass tool (supplied) into the
center of the tile.
(If necessary, use a 3/32-inch bit to drill a hole.) Draw a circle on the tile using the
compass tool and a pencil. Carefully cut out the circle.
2 INSTALL THE BACK BOX
Attach the conduit fitting, lock nut, and safety chain bracket. Attach to the bracket one
end of a safety chain/cable (not supplied) that will support up to 16 pounds (7.3 kg).
Do not attach the other end yet.
Compress the spring clips on the back box and push it through the hole until the clips
spring back. Tighten the screws until you hear a clicking noise. Reinstall the ceiling tile.
Remove an adjacent ceiling tile. Prepare the wiring for camera and lens power; refer to
Tables A and B for wiring distances. Pull wiring into the back box through the conduit
fitting. Attach the safety chain to a support structure. Replace the adjacent ceiling tile.
