The ‘branch shunt’ separates the BUS2 signal into various trunks (branches).
The BUS2 branch shunt is a device responsible for connecting the entry panel with the branch on which the active
terminal (monitor or telephone) is located, isolating the rest of the branches or systems. This shunt enables the
communication of data from the remaining inactive terminals, meaning that they can communicate with the rest of the
system on a data basis.

Status LEDs:
- ON LED illuminated: Input activated. Informs about the input of the active switcher (selected panel).
- FAULT LED on: warns of fault in the bus connected to the input: bus short circuit, fault in connected device,
etc.
The branch shunts can be interconnected to increase the number of branches.
