Installing the Cables

WARNING: Disable the AC power to prevent installer injury and damage to the unit.

Cables are installed using 2 different methods, depending on the installation type. For the in-ceiling
installation, cables are routed from above the ceiling through a conduit fitting on the enclosure to the
customer interface board. For the pendant installation, cables are routed from the inside of the housing to the
customer interface board. In all cases, there should be minimal wire slack at all connection points. After wiring
is complete, dress the cables so they are up over the board. Each camera dome version requires some
different wiring connections. Refer to Figure 19 for individual customer interface board connections.

For an In-Ceiling Installation

1. Place all cables through the conduit fitting on the side of the enclosure. Verify that all cables have been

routed through 0.75 inch (19 mm) rigid or flexible conduit pipe.

NOTE: If conduit pipe is not used, the supplied strain relief fitting must be installed in place of the one

installed to provide sufficient cable strain relief.

2. If using flexible conduit, cut all cables to their approximate required lengths. Leave approximately 1 inch

(25 mm) extra for termination. Tighten fitting.

3. Remove terminal blocks from the accessory kit. The 2-pin is for power, the two (2) 8-pin are for alarms

and control/relay; the 3-pin is for UTP option.

4. Strip approximately 1 in. (25 mm) of the cable outer jacket used for power, control, UTP video (optional),

alarms and relays. Then strip approximately 0.25 inches (6 mm) of insulation off of each individual wire.

5. Terminate the video (coaxial) cable with a BNC type male connector. Terminate the 8-conductor alarm

cable and relay/control signal cable.

6. Make all connections to terminal blocks TB1 (power), TB2 (alarms), TB3 (relays/control signals) and TB4

(UTP video) with reference to Tables 2A, 2B and 2C, depending on version. On TB3, the COMMAND IN
+ (COMM IN +) and COMMAND IN - (COMM IN -) connections must be used for Simplex operation. For
Half Duplex operation, the additional signals RESPONSE OUT + (RESP OUT +) and RESPONSE OUT -
(RESP OUT -) must also be used.

7. Install the terminal blocks TB1, TB2, TB3 and TB4 into the Customer Interface Board at the proper block

frames.

8. Install the video BNC cable connector to the Customer Interface Board’s mating BNC connector for the

standard version.

ALTERNATE CONNECTION:

For the model using the UTP video connection, use the

twisted-pair video wires. Attach each wire to screw terminal TB4. This signal is polarized and specific wire
connections (+ or -) are marked on the board. Refer to the instructions supplied with the receiver for
those connections. For fiber version, use standard ST connector on “daughter board.” For ViconNet,
connect an RJ-45 connector to J1 on the board.

9. On installations not using flexible conduit, slide back excess cable and insert the conduit pipe into the

conduit fitting and tighten the screw.
