48 Tempest®900 2-Channel Wireless Intercom System
Wired Intercom Interface to the BaseStation
Each of Tempest’s twohardwired 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.
Tempest BaseStation Wired Configuration Controls for Connection to Wired Intercom Systems
These controls will normally be used together to configure the Tempest BaseStation for 2-Wire or 4-Wire operation.
• CHAN A has been set for no wired intercom connection – the LEDs are OFF.
• CHAN B is set for Clear-Com 2-Wire intercom connection. The upper slide switch is in the middle position and the
2-Wire LED aligned with CHAN B is illuminated.
