* 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

For the camera dome to operate properly, line

voltage must not go below the worst-case low line

voltage shown in the following table. Make cable

lengths as short as possible to minimize affects of

low line voltages. As shown in the table, maximum

cable length depends on the Class 2 LPS (low

voltage) ac source (such as a J-box) and the worst-

case low line voltage. These lengths are for

Sensormatic composite cables, which use 18

AWG

ac power wires.

Note: Typically, distances are used that provide

a 15% margin between nominal and low line

conditions. For example, if the nominal voltage is

120Vac, restrict cable length to that associated

with 100Vac (0.85 x 120).
