Its been beeping for ages and im sick of it, ive tried sliding as it says to but ive had no luck...

  • That slide to remove is probably for the entire unit, not just a cover. Are you sliding the whole thing?

  • It feels like if i try to slide it any harder itll break off. Ive tried sliding just the bit that looks like a cover as well as the whole thing

    That entire plastic shell - everything visible - is what comes off. There are no seams.I suspect the resistance you're feeling is actually the latch. If it's not, and merely removing the cover breaks it, then it's a defective unit. "old plastic rot" is not a problem for smoke detectors, since smoke detectors have a service life (owing to the internal radiation source which decays to uselessness; don't worry it can't harm you).

  • “Slide” is probably a misnomer. It should read “pull”.

I was wondering the same thing and noticed there is a little latch under the text "slide to remove" which had to be lifted (with a screwdriver) to get the unit out from the ceiling. At least in Finnish version there was a text "lift the latch to slide unit off" which I noticed when I took a picture below the lid.

I know it's an ancient post but I thought this might help someone! :)
