When your smoke detectors battery is dying, it chirps every 30 seconds to remind you to change it. I am in middle of my Friday night meal when this began. May I move the smoke detector to a area where it will not disturb me with a Shinui, or is there any other ideas that are Halachically permissible?

Cover it with a heavy blanket if possible. –  sam Apr 21 '13 at 3:10
@Sam: That is a bit rough if it is hanging on the ceiling or wall. –  Gershon Gold Apr 21 '13 at 3:16

Hinting to a non jew to help you (without telling them explicitly) could do the trick. Before you find someone to remove the battery place a chair underneath ceiling where the smoke alarm is. Although it could be considered dangerous to have a non-functioning smoke alarm over shabbat, it may be a temporary solution before you can replace the battery.

If its still light outside on friday night and you've brought shabbat in early, it may be permissible to ask someone explicitly, even a Jew who hasn't brought shabbat in yet (needs source?).

the orchot hashabat says (chelek 2, perek 23, footnote 46): "...the only heter of hinting [to a non Jew] is by means of removing a thing which is a nuisance, like extinguishing a candle [when trying to sleep], or in a case whereby he is only increasing benefit e.g. hinting for him to add an additional candle, for in these cases there is no issue of increasing benefit from a non Jew's melacha... this is only permitted by 'derech sippur', not directly asking them" (my paraphrasing).

By extrapolation one could be allowed to hint to a non Jew to remove the battery from something that is being a nuisance, like a dying smoke alarm. This can not be via a direct command. Something like "hello, isn't that noise annoying" would be an example.

Someone I know, who knows halacha, suggested to me tentatively that a smoke detector is movable (it is a keli shem'lachto l'heter or, at worst, a keli shem'lachto l'isur, still movable under the circumstances) and that one could remove it from the wall (if it's not screwed in, as many are not) and hide it in a room where it will not be heard. He was unwilling to recommend I rely on this suggestion, but saw no reason it should be incorrect. As always, consult your own rabbi for a final ruling.

This is my eitza too. I have done this with rogue alarm clocks. One shita though that i personally don't agree with but should be considered is that anything permanently attached to a house, no matter how loosely, would be a problem of Soser when removing and Binyan when attaching. So yeah, cylor. –  user6591 Dec 17 '14 at 2:30

Here's what you do:

You get a clean trash can or bucket large enough to fit over the smoke detector. Line the bottom of it (and sides if possible) with cloth/blankets whatever (but not so much that the cloth touches the detector and possibly presses the button).

Then scavenge the house for barrels, boxes, laundry baskets, whatever, and some books. Next have someone hold the bucket over the detector and build a huge stack of those items under the bucket - use books for those last few inches to press the bucket tightly against the ceiling. Making it tight seals in the sound, and also prevents the tower from tipping.

Pro tip: Without the cloth, this also works for lights that were turned on by mistake - but make sure it's either a florescent bulb (which don't get very hot), or use a very large bucket so the bucket doesn't get too hot. (I would wait 20 minutes, then feel the bucket to make sure it's OK.)

That sounds like a fair but of work, and may cause one to sweat, no? –  Zachariah Jun 21 '13 at 13:15
@NewAlexandria Why does sweat matter? –  Ariel Jun 26 '13 at 1:56
sweating is a measure that the action being done is work. Exceptions would be cases like walking to synagogue in a hot climate area, or enjoying marital relations. –  Zachariah Jun 28 '13 at 8:02
@NewAlexandria Sweating has nothing to do with work. Nothing. Whoever told you that was completely wrong. You can ask that as a question if you like, but be prepared for answers like "Where in the world did you hear that?", and "Why do you think sweating has anything to do with work?". Work has to do with certain creative actions. It's not the amount of work that matter, it's the creation that matters. –  Ariel Jul 17 '13 at 8:12
Ariel and @Zachariah (New Alexandria?) -- see judaism.stackexchange.com/q/28239/5323, which is a relevant question (I think) –  Shokhet Dec 17 '14 at 2:01
