電源：保證功率夠，盡量使用線性電源，門鎖和控制器應分開供電，電源安裝盡量靠近用電設備，避免受到干擾或傳輸損耗。

布線：分為電源線、通訊線、信號線等，布線時注意強弱電分開走線，兩管相隔大於20cm左右。

布線採用的線材有以下要求：

電源線：線徑要夠粗，採用多股導線;

信號線和通訊線：使用屏蔽五類雙絞線，其中485總線必須使用雙絞的一對線連接，線材建議使用4*0.5的四芯屏蔽線。

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.
