Cables and Wiring
●
When there are multiple cores in one parallel line, only one pair of closed
cores are allowed to transmit signal. It is not allowed to use multiple pair
of cores in one cable to transmit signal.
●
When using parallel lines, it is suggested to use those with shielding layer.
If dual core or multiple core parallel lines without shielding layer are
routed, stability of signal transmission can be effected. You need to run a
test before installation.
●
Impedance of cable should not be over suggested value, or distributor
cannot transmit enough power to indoor station or door station.
●
Strong electricity and weak electricity cannot be wired in the same route,
they need to be wired separately and the distance should be more than
0.5 meter.
●
All the cables used need to follow the restriction in the following table.
