i usually disconnect mine when i am going to fog my room as it will set the detector off, if you wanted something a bit easier you could probably get like the lid from a CDR container and stick it over top of the smoke detector

A damp rag over the smoke detector will catch most of the fog and avoid setting it off.
If you live in the US and your house is new, taking the battery out won't disable it. The battery is just a backup.

Or how about, you replace the speaker with an LD! That way, when the fog machine sets it off, you would get a nice pulsed light show ;D

Yes, they do set off smoke detectors. I was recently using one in one of the buildings here at the University of Texas at Dallas and set off the detector. What I didn't know is that the detector sets off the fire alarms for the entire building. After evacuating, the UTD fire brigade comes 5 minutes later - a single university policeman with a fire extinguisher. Good thing there wasn't a real fire!

Ha, funny you should bring this one up, I work at seaworld and we were trying to make a fog wall to project some video onto for Journey to Atlantis, after about 5 minutes of fog, the fire alarm went off and it emergency stopped the ride.. good times, we got many dirty looks that day, lol.

Yep, fog machines will set of almost every type of detector there is, ecxept for the sprinkler ones, they use heat to set off. Since i am a dj, well sort anyway, i use a hazer, which is alot different to a fog machine, and doesn't set off ny smoke detectors, apart from the optical ones, which are rare anyways :)

Hazer is essentially a fogger with a turbo fan on the front. The effect being it spreads the particles out more and so, they hang longer.
Also they take more concentrated/ different juice to foggers.
Hazer = better for lasers because it better allows the reflected light back to your eyes.
