* Power, data, and video cables can be ordered
separately or within a composite cable that can be
ordered in various lengths. Plenum-rated cables
must be used in indoor ceilings used for environ-
mental air return (called "other air space" in the
National Electrical Code). Order parts through
your distribution network.
Note: If you order cable from an outside
source, wire colors may be different.
** Belden 88760 (plenum), or Belden 8760 cable
(non-plenum) cable is recommended. Plenum-
rated cables must be used in indoor ceilings used for
environmental air return (called "other air space" in
the National Electrical Code). Order
cable directly
from Belden by calling 1-800-235-3361.
Power Cable
The camera dome and housing are to be
connected to a Class 2 LPS, 24Vac, 80VA power
source. Do not exceed the maximum outdoor Class
2 ratings of 30Vac, 100VA.

Appendix B:
Troubleshooting
This section covers what to do when:
• Dome does not respond to commands
• Fans do not turn
• Picture is grainy or discolored
• Poor video
• Ice forms on bubble.
Dome Does Not Respond to Commands
Follow steps until the problem is corrected. See
page 9 to order parts.
1. Detach the camera dome from the base and
check the address switches. Are they set
correctly?
- YES: Continue.
- NO: Set the correct address and reconnect
the dome.
2. Verify power is reaching the housing. Press
and hold switch SW2 on the environmental PC
board and observe the green (ac power) LED.
Does the LED glow steadily?
- YES: Reattach the dome and continue.
- NO: Check power at the J-box and ac
cable connections at connector P7 on the
other side of the environmental PC board.
If OK, replace the PC board.
