If the power supply has no PE connector, the
MOD-PE-GND
module can be used, available from
Aco, to connect the PE conductor to the intercom system.
Maximum lengths of signal cables (of the line or bus).
The cross section (resistance) of the bus for digital transmission and audio track (LINE terminals)
has a significant impact on the maximum bus length for both Audio and Video systems. For typical
cable cross sections (0.5mm) the maximum distance is 300 m.
This distance increases with increasing wire cross section:
- with 1 mm
2
wire the distance can be increased to 400 m
- with 1,5 mm
2
wire the distance can be increased to 600 m
- with 2,5 mm
2
wire the distance can be increased to 1000 m
Use CDNV-RJ45 module to increase the cross-section of the above mentioned cables (UTP) in the
video system. When necessary, the video signal should also be amplified with the CDNVRAU-DIN
splitter, using the amplified output.
PLEASE NOTE! For proper operation and to ensure safety of
use, connect the panel in its installation point to earth by
connecting the grounding terminal (see picture) on the panel
with a suitable protective installation (PE).
Panel power connection:
Transformer - TR 11.5V AC
