Clear-Com Tempest 900 Reference Manual

48 Tempest®900 4-Channel Wireless Intercom System
Wired Intercom Interface to the BaseStaon
Each of Tempest’s hard 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 compable brands. Each Tempest intercom channel can interface with one intercom system at any given me.
While it is possible that both 2-Wire and 4-Wire systems may be connected to the same intercom channel simultaneously,
they cannot funcon at the same me, and this arrangement has the potenal to cause undesirable operaonal
complicaons, so is not recommended.
