Wired Intercom Interface to the BaseStation
Each of Tempest’s twohard wired intercom channels can interface with a 4-Wire matrix intercom or a 2-Wire party-line intercom. Tempest
supports a 4-Wire intercom interface to most major digital matrix intercom systems and other intercom 4-Wire devices. Tempest also interfaces
with 2-Wire intercom systems including Clear-Com, RTS, and AudioCom (BAL) systems, as well as compatible brands. Each Tempest intercom
channel can interface with one intercom system at any given time.
While it is possible that both 2-Wire and 4-Wire systems may be connected to the same intercom channel simultaneously, they cannot function
at the same time, and this arrangement has the potential to cause undesirable operational complications, so is not recommended.
