How do I replace my Smoke And Co Alarm Because Of This!?

So I am wondering, How do I Replace My Smoke Alarm if it’s over 10 years if it also detects Carbon monoxide that is supposed to be replaced 5-7 years???

Replace it after 7 years because of the CO detection.

Ohhh ok got it, Tysm

So since it is CO and Smoke detection it should be replaced after 7 years. The CO detection short-lives everything.

Yeah that’s true……….

I’d recommend posting it in the “Fire Alarm Help” category of the community that way it makes it easier for members to answer your question for future reference.
