Comment on And now I'm reminded I have two of these to repair.
spicehoarder@lemmy.zip 4 days agoDon’t these things run off of decaying isotopes? I don’t think you can fix that
They run off batteries, using either isotope decay or light sensor (or both)
I actually have one hanging off my ceiling right now, it’s battery was fine, but it tripped likely due to dust or a spider on the optical sensor. It went off at 2am, network sent them all off, took me 10m to find the right one I wasn’t about to just blow it out and out put it back on the ceiling :)
Depends on model. Almost all older ones does (using radiation from the isotope to electrically charge smoke particles that pass through, which then can be detected by a sensor).
Many newer ones are optical.
The A-241 does not charge the particles, it ionizes the air in a small chamber that allows a steady current. Any smoke particles disrupt these currents to set off the alarm.

I’d take back those words that have hurt you
