Will a fog machine set off an alarm in a school

1 laser 2 derby and a moonflower

Thanks for all the input!

I will have a talk with the janitors and staff, also find out at the fire dept too. And find out if shutting them off is an option. I have a hard time thinking that they would shut them off completely.

me and my friends set off our alarm with my hurricane 900

Was it in a commercial building? And how thick was the fog?

I just want enough to show off my scanners and 4play
