你的是不是全靠电池驱动,还是电池只是备用?做一下RESET 试试
The smoke alarm must clear errors after the battery is changed, but it might continue to chirp even after you change the batteries. This usually occurs in electrical powered smoke alarms with a battery backup. When this happens, the way to stop the chirping noise is to reset the smoke alarm to manually clear the error from the processor.
