Wiring and addressing the dome

Wiring the housing board
To wire the housing board, see Figure 13 on page 34 and Figure 14 on page 35 and do the following:
1. Connect the facility Ethernet cable for digital video and data.
2. Connect the facility power cable. Make sure that the power cable is fed over the top of the upper
bracket and down beside the power connector. Use the provided 2-pin terminal strip. If you are using a
heavier gauge cable, ensure that it is properly seated in the connector. Power in the Legend IP domes is
not polarity sensitive.
When power is received by the housing board through the power connection, the housing board’s
diagnostic power LED will appear orange. There are additional diagnostic LEDs that indicate the
proper installation of the camera assembly (see
Installing the camera assembly and bubble on
page 41).
3. If you are installing alarms and relays, connect the alarm and relay cables to the two provided 12-pin
terminal strips. One is blue and one is green.
• Use dry contacts for alarms.
• Use relays with a maximum operating voltage of 30 VAC, 30 VDC at 0.5 A.
Note: Because of space constraints, if you are installing more than five alarms and/or relays, use a multiconductor
cable instead of individual single-pair cables
.
4. If you are installing analog video, connect the facility analog video cable.
• If you are installing UTP video, use the provided green 12-pin UTP terminal strip. It provides
connections for UTP video, in addition to alarms 7 and 8 and relays 1 and 2.
Note: If you have earlier analog Legend domes, be aware that the terminal strip providing the UTP video
connections has been flipped upside down in later domes. Read the decal to ensure you connect to the
correct terminals.
• If you are installing coaxial video, locate the BNC connector.
Note: Use only crimp-on BNC connectors. Do not use screw-on connectors.
5. If you are installing analog data, connect the facility analog data cables to the main connections, which
are the orange B and A terminals on the provided green 4-pin terminal strip. The AUX connections
(yellow B and A terminals) are wired only if you want streaming position reporting or are using the
Tyco/AD (RS-422) protocol.
The main data connections on the terminal strip are for control wires that
are coming in from the keypad. You may also daisy-chain the data signal on to additional domes.
If you are installing RS-485 data, float the shield at the dome and ground it at the keypad.
For details about streaming position reporting, see the Legend IP User Manual (1055713).
WARNING: DO NOT run any cables next to the heaters. Doing so could damage the dome or cause an electrical fire.
CAUTION: To ensure the security of your surveillance system, your IP network should be isolated and secured from
unauthorized access.
