Suspended Ceiling Installation
1. 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.)
NOTE: The ceiling tile cannot be thinner than 0.50-inch (1.27 cm) or thicker than 1.75 inches (4.45 cm).
2. Draw a circle on the tile using the compass tool and a pencil. Carefully cut out the circle.

3. Attach a conduit fitting (not supplied), safety chain bracket, and lock nut (not supplied). Attach one end of a safety chain/cable (not
supplied) to the bracket, which will support up to 16 pounds (7.3 kg). Do not attach the other end at this time.
4. 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.
5. Remove an adjacent ceiling tile. Prepare the wiring for camera and lens power; refer to Table A and Table B on page 8 for wiring distances.
Pull the wiring into the back box through the conduit fitting. Attach the safety chain to a support structure. Replace the adjacent ceiling tile.
