4.1 Access Control Networking Wires and Wiring
1. RS485 communication wires are made of internationally accepted shielded
twisted pairs, which prove effective to prevent and shield interference.
2. The power supply is 12V DC converted from 220V.
3. The Wiegand readers use 6-core communication shielded wires (RVVP
6×0.5mm) (usually there are 6-core, 8-core, and 10-core types available for
users to select according to the ports) to reduce interference during
transmission.
4. As an electronic lock has a big current, it generates strong interference signal
during an action. To reduce the effect of an electronic lock during an action on
other elements, 4-core wires (RVV 4×0.75mm
2
, two for a power supply and
two for a door sensor) are recommended.
5. Other control cables (like exit switches) are all made of 2-core wires (RVV
2×0.5mm
2
).
6. Notes for wiring:
Signal wires (like network cables and RS-485 wires) can neither run in
parallel with nor share one casing pipe with large-power electric wires
(like electronic lock wires and power cables). If parallel wiring is
unavoidable for environmental reasons, the distance must be over 50cm.
Try to avoid use of any conductor with a connector during distribution.
When a connector is indispensable, it must be crimped or welded. No
mechanical force can be applied to the joint or branch of conductors.
In a building, distribution lines must be installed horizontally or vertically.
They should be protected in casing pipes (like plastic or iron water pipes,
to be selected according to the technical requirements of indoor
