When someone walks over a certain part of the loft floor, all the smoke alarms in the house beep (lemmy.world)

Honestly I am so bloody baffled by this.

I removed the smoke alarm that would be affected by vibration from the loft floor (which was in the room directly underneath), but the other alarms still go off when someone walks up there (they're all wired together, so when one goes off they all go off). I removed the one that's in the loft too, but it still happens.

I have no fecking idea what else to do 😅 should we go in under the loft floor to have a look, or into the ceiling underneath the loft floor? Any suggestions for what to look for? Should I be concerned that vibration is affecting wiring? Is it spooky ghosts?

Sounds like there might be a loose connection which is getting jiggled?

Thanks very much, I can't believe I didn't think of this - I think I was just so frazzled by the alarms blaring my brain couldn't think properly. I'll be lifting up the floor for a look tomorrow!

I presume your alarms are wired into the main electrical system. Are they also connected to each other using the red wire? This is typically used so that if one alarm detects fire/etc, all of the others start alerting as well

As an added hint, your smoke alarms might have something indicating which one specifically set them all off. Mine flashes red from that one every 30 seconds or so until it gets reset.
