Tempest®2400 2 -Channel Wireless Intercom System 31
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 additi 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 connecti on is an audio-only interface to 4-Wire systems. Data
can be present on the input cable but no data is uti lized in the Tempest BaseStati on.
Steps to Confi gure a 4-Wire Intercom Connecti on
• Select 4-Wire connecti on for the appropriate channels.
• Make the physical connecti ons with RJ-45s, to the Tempest BaseStati on and the 4-Wire system.
• Confi 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 BaseStati on. Select
the 4-Wire setti ng as described in “Wired Intercom Confi gurati on Controls.” That is all that is necessary for Tempest to be
ready to communicate with the 4-Wire system. Perform any necessary confi gurati on for the 4-Wire intercom System and
the communicati on link should be complete.
The top RJ-45 jack is for Channel A and the bott om RJ-45 jack is for Channel B.
You may choose to adjust the IN/OUT levels on the front of the BaseStati 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 operati on. Tempest
uti lizes RJ-45 jacks for 4-Wire connecti on to the BaseStati on. Only two pairs of wires are uti 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.
