We have this same smoke alarm in our house! It is on the second floor, and it surprisingly STILL works. The only times I've ever heard it beep were when testing it, and the low battery warning.

There is a version of this still made in the original factory in Ireland and sold in Europe - Ei Electronics

I've changed the battery in mine and still can't get it to stop beeping.

The test button on the GE alarms pushes a metal plate on the americium 241.

It's amazing how so many people, even ones who may have gotten an A+ in geometry, still call this a square-shaped unit!

wow thats one loud ass sound it scared me to death

[Federal3t22]

in my girlfriend's late mother's plate she had the black and decker verson of this smoke, which did the slower 4/6 beeping. I still regret not snagging one when I had the chance.
