Wiring and Setup
Location Planning
Both wall- and rack-mounting versions of Multicom 2000 should be located centrally to the rooms to be served to
minimize the length of cable runs. Consider the following requirements when choosing a location.
• The location should be well ventilated and dry. Avoid rain or moisture or areas likely to be exposed to these hazards.
• Do not locate the system near heat-generating sources such as direct sunlight, radiators, or warm air ducts.
• There should be enough room to open the door of the cabinet mounting system. In the case of a rack installation,
there should be sufficient access to the rack door or enough room to move the rack to gain access.
• Where possible, do not locate it in a carpeted room, especially one where a lot of static is present. If this is not
possible, the installation of an antistatic mat below the control center is required.
Wiring Requirements
Class II wiring may be used for station wiring. Support wiring to prevent strain or sagging. Knockouts are provided
on the wall-mounting enclosure or rack to admit wiring.
All stations use the same type one pair shielded 100% coverage of aluminum polyester foil with drain wire and one
unshielded pair, such as West Penn #357 or Belden #8724.
(See Figure 7).
The cable from each station must be terminated to Bogen connectors (2518, 2520, 2522), which are then connected
to the interface pins on the relay card or module. Failure to use the proper connectors, recommended wire type, or
use of solder to terminate the cable to the relay card pins will void the warranty.
Installation Precautions
The following precautions are mandatory when installing the Multicom 2000, or when making changes to the equip-
ment and wiring after the initial installation.
• Disconnect all 120V AC power sources before making any changes in system equipment or wiring.
• Wear a properly grounded conductive wrist strap when working at the control center or at any staff
station where the wiring for the staff station is connected to equipment at the control center.
• Use care when running wire from the station equipment to the control center. Keep all wiring well
isolated from 120V AC (and higher) power lines.
NOTE: Use grommet edging material to prevent abrasion against sharp edges of knockouts of rack.
