Replacing built in CO/LP detector
Anyone replace the built in detector? I know the free mounted ones have a 7 year life but what about the built ins. IIRC I think mine shows a redlight or something that said it bad. I do have the wall...

On mine I had to take it down from the wall to read the expiration date that was stamped on the backside. They all have a life span. Mine would beep occasionally for no apparent reason which was it's way of telling me to replace it.
