My smoke detectors have been chirping for a while. I checked the 9v battery with the multimeter to see if they died. Nope, still good I checked the detector’s sticker on the back and saw it was made in 2003. They’re 20 years old now and I guess no longer good. So, I ordered a new pack of hardwired interconnect detectors.
You have shamed me into installing all new detectors. I know that the internals fade and stop working right after about 10 years…I’m 20+ years in my house. This weekend is smoke detector changeout week - thanks for nothing, friend - now my Saturday is shot ;)
Sounds like an action-packed weekend to me
