Cable Requirements

Data Cable
The table below shows requirements for
SensorNet, RS-422, and Manchester networks. For
more information about communication protocols
and cable networks, see Communication Protocols
and Cable Networks, 8000-2573-19.

* 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 environmental 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
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).
