Wiring The Housing Board - GE Legend Installation Manual

Wiring the housing board

To wire the housing board, see Figure 10 on page 16 and Figure 11 on page 17 and do the following:
1. Connect the facility data cables to the MAIN connections. The AUX connections are for future use. If
you are installing RS-485 data, float the shield at the dome and ground it at the keypad.
Get the provided green 4-pin terminal block and connect the cable to the marked terminals. The MAIN
data connections on the terminal block are for control wires that are coming in from the keypad. You may
also daisy chain the data signal on to additional domes. The AUX data connections are for future use.
2. Connect the facility video cable.
• If you are installing UTP video, use the provided green 12-pin UTP terminal block. It provides
connections for UTP video, in addition to alarms 7 and 8 and relays 1 and 2.
• If you are installing coaxial video, locate the BNC connector.
Note: Use only crimp-on BNC connectors. Do not use screw-on connectors.
3. 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 power terminal block. If you are
using a heavier gauge cable, ensure that it is properly seated in the connector. Power in the Legend
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. It appears orange because the red and green internal
LEDs both illuminate. There are additional diagnostic LEDs that indicate the proper installation of
the camera assembly (see
4. If you are installing alarms and relays, connect the alarm and relay cables to the two provided 12-pin
terminal blocks. 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.
When flashing software upgrades to the dome over a standard IP network via the dome's Ethernet
CAUTION CAUTION
connection, ensure that the network is secured from unauthorized access. Like all Ethernet connections, the
dome's Ethernet connection has no security against unauthorized access. You may consider connecting the
Ethernet cable only when you are flashing the dome, unless you have the dome connected to a secure,
isolated network.
5. If you want to flash software upgrades to the dome, connect the Ethernet cable.
