The issue is NOT the Americum but the natural degration of the photoelectric cells and the accumulation of dirt within the test chamber.
Even before that time the risk for false alarms is increased substantially by degration before the chances for sucessful alarming decrease rapidly. Due to that they actually withstand aging actually worse than ionisation based devices.
Sientific sources?
here.
(Besides: Americum has a decay time of over 400 years,btw)

Your third source is about the 2020 follow-up study of the 2017 study in your first source. You’ve “only” (in scare quotes because that’s still plenty) got three independent sources even though it looks like four.

A follow up is a absolutely regular thing and does not diminish neither study.

I didn’t say they were diminished. I said they weren’t independent.
