Can the smoke from blowing out a few candles set off a fire alarm?
Answers:
Sure, it could. But most likely, unless you were right under the detector, it wouldn't.
I assume you are just talking standard smoke detectors. I have occasionally worked with laser and other "high sensitivity smoke detectors" which would pick it up. (I have even seen one that picks up someone rubbing a match on a striker without actually striking a flame!) But unless you are in a computer room or a laboratoy, I seriously doubt you'll have any of those.

It depends on how old you are.

Yes any sort of smoke can set off a fire alarm. Fire alarm senses smoke of any kind.
well it depends what kind of fire alarm you got, if you got a really cheap one, then no it probably wouldn't, but if you get u'res through a sercurity company then it probably would.
No. It would not be a good one.
If you have about a 100 candles going out the same time.
Yes it can. Smoke is smoke and the smoke detectors cannot tell the difference. If you blow smoke from a cigarette into a smoke detector it will set it off. Starting a dirty oven can set a detector off as well as food cooking over in the oven and food burning on the top of the stove will also.
