When Does the Life Span of a Carbon Monoxide Detector Start

Published 09/17/2021

Question:

I understand that the AT31011 is no longer being made. An Rv parts department that I contacted has some still in stock. Because these units are built with end of life time limitations are these units already expired? How are the years of use calculated? Thank you

Typically the life span of the carbon monoxide detectors doesn't start until the first power up. So they are most likely still good. We also carry detectors for gas and carbon monoxide should they no longer have any.
