Modular System

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
● 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.
