Master Slave Connection Diagram 16 - Tech Works CI Series System Planning Manual

The Audio, and Alert Outputs are a function of what the user needs for the application.
No jumpers; No outputs!!!
Install all of the Audio Source Jumpers, and set the MUX to "Always" and you get everything, all
of the time.
Install the Master and Slave Audio Source Jumpers, set the MUX to Always, perhaps this is a
Ceiling Speaker for the "This Room" (Where the Local Microphones are located).
Install the MIC and PA-BUSS Audio Source Jumpers, set the MUX to Always, perhaps this is a
Ceiling Speaker for the "Operator".
Install the MIC Audio Source Jumper, Key the MUX with the TALK SWITCH, the Microphone
could be used for Logging or Paging.
The ALERT control signal indicates a Special Function is required.
For example, the PA-402 may respond by replacing Background Music with Communications.
Key the ALERT with the CI-BUSS and Talk Switch...the Music goes away if someone is talking!
There are hundreds of ways to configure the PA-OUTPUT Functional Section, one of five
Functional Sections of the MSI-22!!!
And, the MSI-22 may be connected to many other Configurable BUSS products!
Including another MSI-22!
Simple systems may require a single Box; more complex systems may require several boxes.
The Collaboration Intercom Buss, CI-BUSS; has bi-directional Audio pathways for
Communications, and Control.
While Program/Paging applications are handled by th PA-BUSS for one way Audio
Communication and Control.
Expansion is easy; units daisy-chain together to form Collaborative Groups.
