50 Tempest®24 00 4-Channel Wireless Intercom System
Wired Intercom Interface to the BaseSta on
Each of Tempest’s hardwired 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.
