General notes on the cabling in TCS video systems

Terms for 5 wire and 6 wire operation

6 wire operation

5 wire operation
6 wire operation
The cabling depends on the building situation and is only limited by its length.
• When selecting the cable length consider: the loop resistance M-P must be max. 8 Ω
(table 1).
• For loop resistance > 8 Ω: provide for multiple wiring of the lines (twisted pairs).
• choice of line or star wiring
• Do not use more than 6 video in-house stations per line. For systems with more video
in-house stations provide for the use of video distributors (VT02, VT04).
• up to 64 front-door stations and an almost unlimited number of in-house stations can be
connected polarity-free (a/b) to a system. (use suitable power supply and control unit.)
