门禁控制器的安装要考虑到控制器和读卡器之间的距离，理想的传输距离是100m之内。对于信号传输电缆，必须考虑电缆屏蔽和因远距离传输带来的信衰减，在管路施工过程中，应采用材质为钢材的线管和电缆桥架，并做好可靠接地。
The distance between the controller and the card reader shall be considered for the installation of the access controller. The ideal transmission distance is within 100m. For signal transmission cables, cable shielding and signal attenuation due to long-distance transmission must be considered. During pipeline construction, steel conduits and cable trays shall be used, and reliable grounding shall be done.
门禁系统施工中布线需要注意
Attention shall be paid to wiring during construction of access control system
1、所有走线都必须套管， PVC管和镀锌管都可以，避免老鼠咬断线路引起故障。强烈建议：本系统的所有走线必须同220V强电线分开套管
1. All wiring must be sleeved, PVC pipe and galvanized pipe can be used to avoid faults caused by mouse biting the line. It is strongly recommended that all wiring of this system must be separated from 220V strong wires
2、虽然控制器具备了良好的防静电、防雷击、防漏电设计，请务必保证控制器机箱和交流电地线连接完善，且交流电地线真实接地。
2. Although the controller has a good anti-static, lightning protection and anti leakage design, please ensure that the controller chassis and the AC ground wire are well connected and the AC ground wire is truly grounded.
3、建议您不要经常带电拔插接线端子请务必拔下接线端子，再进行相应的焊接工作。
3. It is recommended that you do not plug and unplug the terminal frequently with electricity. Be sure to unplug the terminal before welding.
4、请勿擅自拆卸或者更换控制器的芯片，非专业的操作会导致控制器损毁。
4. Do not disassemble or replace the controller's chip without authorization. Non professional operations may damage the controller.
5、不建议您擅自对接其他附加设备，所有非常规的操作，请务必先于我方工程师沟通
5. It is not recommended that you connect other additional equipment without authorization. For all unconventional operations, please be sure to communicate with our engineers first
