BELDEN SHIELDED CABLES
Table 1-1: Belden Shielded Cables
Note: For better than 50 dB channel crosstalk
• Portable Installation Cable: Practical cable for portable
system interconnections is flexible, two-conductor, shielded
microphone cable. We suggest using BELDEN #8413 (24
Gauge). For runs longer than 500 feet use a 20 gauge cable
or larger (BELDEN #8412).
• Permanent Installation Cable: Vinyl-jacketed shielded pair
is the cable of choice for permanent installations. Placing the
cable in conduit is recommended but not necessary.
INSTALLING THE STATIONS
First, choose the location for the Main Station or Power Supply. These
units require access to AC power. They should be located away from
other equipment that generates excessive amounts of heat. Also,
choose locations for each Remote Station and Speaker Station.
Choose general locations and areas of use for the beltpacks.
Determine the locations for other Clear-Com equipment which will
connect to the intercom lines. The choice of location will depend upon
and often define the wiring scheme. It is very helpful to create a
drawing showing where each component will be located as well as
where the wiring will run.
CONNECTIONS
The following sections describe the connections provided on the
intercom stations:
• Intercom Line Connection: The rear panel of Main Stations,
Power Supplies, Remote Stations, and other stations contain
between one and three 3-pin male XLR connectors for each
