Tempest®900 2-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 addition to intercom audio, most systems have separate data lines that carry system data
from the matrix to the remote devices. The Tempest 4-Wire connection is an audio-only interface to 4-Wire systems. Data
can be present on the input cable but no data is utilized in the Tempest BaseStation.
Steps to Configure a 4-Wire Intercom Connection
•
Select 4-Wire connection for the appropriate channels.
•
Make the physical connections with RJ-45s to the Tempest BaseStation and the 4-Wire system.
•
Configure 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 BaseStation. Select
the 4-Wire setting as described in “Wired Intercom Configuration Controls.” That is all that is necessary for Tempest to be
ready to communicate with the 4-Wire system. Perform any necessary configuration for the 4-Wire intercom System and
the communication link should be complete.
The top RJ-45 jack is for Channel A and the bottom RJ-45 jack is for Channel B.
You may choose to adjust the IN/OUT levels on the front of the BaseStation 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 operation. Tempest
utilizes RJ-45 jacks for 4-Wire connection to the BaseStation. Only two pairs of wires are utilized - 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.
