General information on the conduit in TCS video systems
6-wire operation
The 6-wire operation is the standard operation mode. Two separated ground lines (b and
M) are used in video operation. The conduit depends on the structural conditions and is
only limited by the length.
Observe when selecting the length of the lines: a loop resistance a-b and M-P of max. 8
Ω has to be observed (table 1).
In case of loop resistance > 8
Ω: plan multiple wiring of the strands (double twisted
lines).
Wiring optional in strand or star structure.
Do not use more than 20 video indoor stations per strand. For systems with more video
indoor stations use video distributors (FVY1200, FVY1400).
Up to 64 front-door stations (16 of them video front-door stations) and almost an unlim-
ited number of indoor stations can be connected polarity-free (a/b; only in 6-wire opera-
tion) in one system. In this case, a suitable power supply and control unit has to be
used.
