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.

0.50-inch (1.27 cm) or
thicker than 1.75 inches
(4.45 cm).

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.

Table A. Video Coaxial Cable Requirements

Cable Type* Maximum Distance

RG59/U 750 ft (229 m)

RG6/U 1,000 ft (305 m)

RG11/U 1,500 ft (457 m)

* Minimum cable requirements:

75 ohms impedance
All-copper center conductor
All-copper braided shield with 95% braid coverage

Table B. 24 VAC Wiring Distances

The following are the recommended maximum distances for 24 VAC applications and are
calculated with a 10-percent voltage drop. (Ten percent is generally the maximum allowable
voltage drop for AC-powered devices.)

EXAMPLE:

An enclosure
that requires 80 vA and is
installed 35 feet (10 m) from
the transformer would
require a minimum wire
gauge of 20 Awg.

NOTE:

Distances are cal­culated in feet; values in
parentheses are meters.

NOTE:

The torque applied
to the camera mounting
bracket nut should not
exceed 40 pound-inches.

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 recom­mended 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.
