Cable types
As a result of national standards and requirements, installation may require a
particular cable type. Note the respective requirements and planning documents.
The following cable types can always be used for cabling the detector line:
●
Twisted, with and without shielding (recommended)
●
Untwisted, with and without shielding
Cable shielding
When using shielded lines (e.g. fire detection cable J-Y(St)Y n x 2 x 0.8 mm),
ensure that the cable shielding is only connected on one side.
The fire control panel's function may be impaired by a missing or incorrect cable
shielding connection. The 'Shield connection terminal blocks' option is available for
the connection. Depending on the installation environment and requirements of
relevant standards, cable shielding may have to be connected and merged at one
central connection point.
The screw terminals for directly connecting the C-NET cable are integrated in every
C-NET line device. The connection terminals with input (+/-) and output (+/-) are
the same for all users, with the exception of the detector base.
