Fire Safety
Up to 126 devices, such as automatic fire detectors, manual call points,
transponders, and other C-NET components, can be connected to the C-NET
detector line.
The connection of the C-NET detector line is on the periphery board. Most line
devices, such as fire detectors, are supplied with the operating voltage required
directly by the C-NET. An external power supply is required for the FDCIO223
transponder.

Line separator
All C-NET devices have an integrated line separator.
In the event of a fault, e.g. a short-circuit or wire break in the C-NET wiring, the line
separator is opened and the C-NET segment is shut down as soon as the fault was
found. The C-NET devices remain functional and ready to detect. The fault is
displayed on the station.
Connection factor (AK, RK, MK)
The number of connectable C-NET devices and the max. line length depend on the
device connection factor. The maximum number of 126 C-NET devices and the
max. length of line of 3300 m may be reduced significantly depending on the type
and volume of devices.
