Clear-Com Tempest 900 - 4-Wire (Matrix) Intercom Interface

50 Tempest®900 4-Channel Wireless Intercom System
4-Wire (Matrix) Intercom Interface
4-Wire intercom systems use two pairs of wires to carry one full duplex channel of intercom audio - one pair for send and
the second pair for receive. In addion to intercom audio, most systems have separate data lines that carry system data
from the matrix to the remote devices. The Tempest 4-Wire connecon is an audio-only interface to 4-Wire systems. Data
can be present on the input cable but no data is ulized in the Tempest BaseStaon.
Steps to Congure a 4-Wire Intercom Connecon
• Select 4-Wire connecon for the appropriate channels.
• Make the physical connecons with RJ-45s to the Tempest BaseStaon and the 4-Wire system.
• Congure the 4-Wire system to recognize the Tempest Wireless system.
• Adjust IN/OUT volume levels between the Tempest Wireless System and the 4-Wire system as needed.
Connect the 4-Wire intercom system to the desired channel RJ-45 jack on the rear panel of the Tempest BaseStaon. Select
the 4-Wire seng as described in “Wired Intercom Conguraon Controls.” That is all that is necessary for Tempest to be
ready to communicate with the 4-Wire system. Perform any necessary conguraon for the 4-Wire intercom System and
the communicaon link should be complete.
The top RJ-45 jack is for Channel A and the boom RJ-45 jack is for Channel B.
You may choose to adjust the IN/OUT levels on the front of the BaseStaon if the volume level between the systems is not
acceptable.
Wiring schemes vary and it is important to ensure that the cable is wired correctly for proper system operaon. Tempest
ulizes RJ-45 jacks for 4-Wire connecon to the BaseStaon. Only two pairs of wires are ulized - one to send audio and
one to receive audio. A standard CAT-5 patch cable can be used to connect between the matrix and the Tempest system.
