Tempest 2400 Wireless Intercom System
Wired Intercom Interface to the Base Station
Each of Tempest’s four wireled 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 Base Station Wired Configuration Controls
for Connection to Wired Intercom Systems
These controls will normally be used together to configure the Tempest base station
for 2-Wire or 4-Wire operation.
• Channel A has been set for no wired intercom connection – the LEDs are off.
• Channel 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 channel B is illuminated.
• Channels C and D have been set for a 4-Wire interface. The position of the slide switch does not
impact 4-Wire operation.
