What tools do you need to prepare for an intelligent engineering access control system?

Power supply: Ensure that the power is enough. Try to use a linear power supply. The door lock and the controller should be powered separately. The power supply should be installed as close as possible to the electrical equipment to avoid interference or transmission loss.

Wiring: It is divided into power lines, communication lines, signal lines, etc. When wiring, pay attention to the strong and weak electric separate lines, the two tubes are separated by more than 20cm.

The wire used for wiring has the following requirements:

Power cord: the wire diameter should be thick enough to use multiple strands of wire;

Signal and communication lines: Use shielded five types of twisted pairs. The 485 bus must be connected by a pair of twisted pairs. The wire is recommended to use 4*0.5 four-core shielded wires.
