Ci-Buss, Collaboration Buss; Ci-Buss, Collaborative Buss Block Diagram - Tech Works CI-HSI-41 System Planning & Installation Manual

CI-BUSS, the Collaboration Buss, allows chaining of several Units:
CI-BUSS "SLAVE"
AUDIO INPUT
CI-BUSS ALERT
CI-BUSS "MASTER"
INPUT AUDIO
In the Standard Configuration all the users of the CI-BUSS talk and listen to each other.
However there may be situations where some users may only listen, or only talk.
There are two Collaboration Buss connectors on the HSI-41. One is Labeled "Master" and the
other is labeled "Slave". The Jumpers illustrated above determine what is sent out of the SLAVE
connector or the MASTER connector.
The Jumper Selections allow selective Collaboration or communication between units on the
chain. So just because something comes into the Slave Connector, does not mean that it has to
go out of the Master connector to the other devices. By moving the Jumpers the installer can
determine what comes in and what goes out of each connector independently. Changing one
selection does not affect another.
These settings do not affect the Monitor/Communications Output, PA-BUSS.

The Call Pair is a "Party Line" passing through to all the Blocks forming a Group.
The Operator Console Responds to a Switch Closure by initiating a Calling Sequence.
All Switches must be floating, or isolated with Opto-Couplers.
The Alert Pair is a "Party Line" passing through to all the Blocks forming a Group.
The Operator Console sends a signal to all the Other Blocks, such as my Microphone is On.
The other Blocks may be configured to "Respond" in an appropriate manner.
Responder Blocks, are electrically isolated, with Opto-couplers.

guide.
