仔细凑近看了看小字：this is not monoxide or alarm 下一行写：will not operate without power. 像是报警系统， 可在它旁边那个白的就明明是monoxide and smoke detector. 搞不懂这个是什么东东

Code requires inside every bedroom you need a smoke detector. Every floor (usually hallway) requires a CO + Smoke detector. All detectors need to include strobe light.

3 year new house these should be hardwired, not sure why it is battery operated. That is against the code. Code requires it. But this is inside your house. No one would know if you remove it.
