3.3.2 Input/output module primary side
Communication
Communication with the control panel takes place via the FDnet/C-NET detector
line.
Configuration is performed on the control panel.
Line separator
All FDnet/C-NET devices are equipped with a line separator.
The FDnet/C-NET device is equipped with electronic switches which isolate the
defective part in case of a short-circuit on the detector line. The rest of the detector
line remains serviceable. On a loop line, all FDnet/C-NET devices remain fully
functional after a simple fault.
