I'm skeptical. Maybe animals can, but people certainly do not wake up from smell (precisely why we need fire detectors).

Can you cite a source for this?

The smell of bacon usually wakes me up, coffee, not so much.

People wake up to smells. The point of the fire detector is that you might not be able to detect it at certain levels. It's also why we have carbon monoxide testers too, since we can't smell that period.

Once it reaches the "You wake up because of X", you might be in a room surrounded by flames and unable to escape...that's the point of having a fire detector to screech at you.

Also smoke doesn't just come in full blast, it does it gradually most times. You may not wake up to it if it were very gradual about it's increase until it became overwhelming. Much like with sound you can sleep through rain, but when a huge lightning strike followed up by rolling thunder will wake you up. Breaking glass is also a good example.

BELIEVE me, when my dog farts in it's sleep, we wake up.
