A paper attached to a street post with a picture of Lisa Simpson rocking back and forth. The text reads “Attention! Hi neighbor! Did you have a smoke alarm that kept beeping once every 60 seconds that you decided to throw in your yard out of annoyance? If so- it’s now annoying me! Because guess what? It’s beeping right outside my bedroom window! Every time it beeps a piece of my soul dies. Please get rid of it, I absolutely beg of you. It’s been a month.“
It may be beeping because it’s past its 10 year working period. Some are programmed to beep continuously after 10 years to signal replacement needed.
Even if they’re permanently wired in with a Li-ion backup battery. I get why they do it, but realistically they’re probably good for longer?
Most of the ones that exhibit that behavior are the types that relay on radioactive decay. decay being the key word there. They get less radioactive over time and need to be replaced.
“I’m sorry, sir, your smoke detectors aren’t nearly radioactive enough to be considered safe.”
Ah, I forgot they rely on decay. Makes sense why 10 years is the lifetime. They use Am if I recall?
It’s the sensors accuracy that is of concern at the 10 year mark, not the battery life
Ah. Didn’t think of that. Makes sense due to how they detect.
Yep! Discovered our rentals smoke alarms were like 15 years old. Got us new ones at least.
TIL.
