Wiring
Wiring is done with runs of cable for power, video and control. Optional wiring can be installed for the relay
output and 4 alarm inputs. All cables enter the enclosure from the top on all Pendant installations and through
the conduit fitting on all In-Ceiling installations. Refer to the Technical Information section for all electrical
requirements.
Power cables carry AC power and are usually a two-conductor type ranging in size from 20 to 12 AWG. The
provided power source is a UL listed Class 2 indoor/dry or Class 3 outdoor/wet rated type transformer. The
leads should be connected to Terminal Block 1 (TB1), pin 1 [H - (hot)] and pin 2 [N - (neutral)]. The size of the
two-conductor cable depends on indoor/outdoor application and cable distance as shown in Table 7 of the
Technical Information section. Refer to the table in the Introduction for power supplies available from Vicon
(single and multi-channel).
Video cables carry the composite video signal and Vicoax signals out of the Surveyor2000 over coaxial cable.
In Vicoax mode, the video signal also carries the control signals. The video cable should be connected to the
BNC female connector J1 for installations using coaxial cable; for UTP installations, twisted-pair video wires
should be connected to TB4. Refer to
able types and maximum distances.

Control cables carry the NOVA/VPS digital signals and require individually-shielded twisted-pair sets. The
NOVA/VPS signals are carried via RS-422/485 protocol. The RS-422 protocol is used for single camera
dome applications. RS-422 signals are always active and do not have a tri-state (high impedance) state. The
RS-485 protocol is used for multiple camera domes in a daisy chain configuration. RS-485 signals are not
always active and do have a tri-state (high impedance) state. Thus, Surveyor2000 can be daisy chained to
any other compatible RS-485 device, including another Surveyor2000. Refer to the Communications/Power
Supply PC Board Shield for signal connection points. The type of cable required depends on the cable
distance and number of wire pairs within a cable, as shown in the Reference section. These signals are
connected to Terminal Block 3 (TB3) or RJ-45 Connector J3. There can be a maximum
