The smoke detector is broken, and the new property needs to be coded. What should I do?

[Reprint] Use a handheld encoder to set the address position in the encoder, and then install a detector to write the address. After hearing a sound (some brands of encoders don't give a sound prompt after successful coding, but display the letter "P" on the screen to indicate success), indicating that the address has been written successfully. Of course, you can also write the address with the address written in the host, but be careful not to write it automatically. If automatic writing is used, the bus address code will be written completely out of order. You can write manually, or disassemble the bus and set the address to write automatically. Of course, at present, the fire alarm host in Xinwo can encode smoke detectors, and other brands of smoke detectors, such as Bei, Songjiang Yunan, Taihe An, etc., must be encoded by encoders, but not by fire alarm hosts.
