4 .
Lift the assembly into the ceiling and rest it on the
5.
Lift the housing above the opening (the wires go
ceiling grid. Route the cabling into the upper
slack). Insert the ceiling tile or ceiling panel option
ing as described in Section 2.1. Attach the
and seat it in the grid. Seat the upper housing in the
sion wires to the holes at the ends of each mounting
opening of the tile or panel. Install the camera as
rail, and adjust the length of each wire so that the
described in Section 2.4
lower edge of the housing is even with the bottom
edge of the ceiling tile when installed.
2.4 Camera and Lens Installation
1.
Mount the lens onto the camera following the cam-
era instruction manual.
2.
Mount the camera/lens combination to the mount-
ing bracket using a
screw. Extend the lens to
its greatest extension and position the camera on the
bracket so that the lens clears the dome by about
inch (0.64 cm). Tighten the screw. (Since the dome
is not installed until later, the camera/lens position-
ing at this time is approximate.)
3.
Connect the video, sync, and power cables.
4. Loosen the bolts holding the camera mounting
bracket, if necessary, to position the camera to view
the desired scene. Tighten the bolts. Adjust the lens
for an acceptable picture.
5.
Cut off the string with the clip on the end from the inside
of the housing (it has no use in this installation). Remove
the trim ring from the upper housing by removing the
four (4) screws and washers. Loosen the nuts on the
clips on the underside of the trim ring and slip the dome
flange into the clips. Refer to Figure 3. Attach the dome
to the trim ring by tightening the nuts. Verify that the
lens clears the dome by
inch (0.64 cm).
6.
Rotate the lower dome until the scene, as viewed on
the monitor, is completely visible through the tinted
viewing strip of the dome. Reinstall the trim ring onto
the upper housing with the four screws and washers.
This completes the installation.
3. MAINTENANCE
The
Omniscan requires no maintenance other
than occasional cleaning of the viewing strip area of the
inside surface and the entire exterior surface of the dome.
3.1 Handling and Cleaning Procedures for Acrylic Domes
The lower dome of the Omniscan is an optical surface
through which the camera must resolve detailed images.
Treat the dome with the same care as a fine camera lens.
Please observe the following precautions to maintain the
dome’s optical properties:
1. Always handle the dome from the outside of its
circular flange.
2.
When handling the dome, avoid contact with the
inside surface.
3. If dust or other contaminants accumulate on the
dome’s interior, they should be removed with clean
air pressure (compressed air cans).
4.
If heavy residue (spots, streaks, stains) or any other
contaminant which is only on the surface of the
dome is present, these can be removed with a
tion of a mild dish detergent suitable for use on
acrylic plastic or isopropyl alcohol and water and
lint-free soft paper towels such as Microwave
Bounty. After cleaning, the affected area of the
dome should be blown off with clean, dry air.
