HARD CEILING INSTALLATION
1
PREPARE CEILING
Locate the center point of the mounting location. Drill a hole in the ceiling using a
3/32-inch drill. Insert the compass tool into the hole. Use a pencil and the compass
tool to draw a circle on the ceiling. Carefully cut out the circle.
2
INSTALL THE BACK BOX
Attach the conduit fitting, lock nut, and safety chain bracket. Install a safety chain/cable
(not supplied) that will support up to 16 pounds (7.3 kg). Install one end of the safety
chain/cable to the safety chain bracket and the other end to a support structure in the
ceiling.
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.
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.

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 adjacent ceiling tile. Prepare the wiring for camera and lens power; refer to

DOME INSTALLATION
1. Snap the clip, on the end of the trim ring leash, into the hole on the lip of the back box.
2. Install the dome by pushing the two ball studs on the trim ring into the retaining clips
on the back box.
3. If you have a dome with black or white opaque finish, turn the dome so that the
viewing slot is in front of the lens.
MAINTENANCE
Clean the acrylic dome as needed. Be careful not to scratch the surfaces of the dome.
Exterior Surface - Clean the dome’s exterior surface with a nonabrasive cleaning cloth
and agent that is safe for acrylic plastic. Either liquid or spray cleaner/wax suitable for fine
furniture is acceptable.
Interior Surface (Except Chrome or Gold) - Clean the same as the exterior surface.
Interior Surface (Chrome or Gold) - The inside surface of a chrome or gold dome is
easily scratched. Use the following precautions to maintain the dome’s surface.
a. Always handle the dome from the outside of its circular flange.
b. Never touch the coated inside surface. The acid in your fingerprints will eventually
etch the coating if the fingerprints are not carefully removed according to the recom-
mended cleaning procedure in item e.
c. If dust or other contaminants accumulate on the dome’s interior, remove the debris
with compressed air. Compressed air cans are available from photographic equipment
or electronic supply dealers.
d. If heavy residue accumulates and cannot be removed with air pressure, rinse with
water and immediately dry with air pressure so that water spots will not remain. Avoid
wiping the coated surface with direct hand pressure - it will easily abrade unless
extreme care is taken. Once scratched, the dome cannot be repaired.
e. If internal wiping is necessary, avoid hand rubbing. Instead, make a wick as follows:
Use a very soft paper towel. Roll a section into a tightly wound tube. Tear the tube in
half, and wet the fuzzy end of the wick with a solution of isopropyl alcohol diluted with
water. Hold the dome with its opening facing downward and wipe the interior of the
dome with the wet end of the wick. Use a circular motion, starting from the outside and
spiraling into the center. Use a new wick for each two passes over the dome.
