I have a strange question here. The place we are currently calling home has a nice basement "garage" in which I plan to brew on Wednesday. This area is intended for storage of gas engine equipment like lawn tractors, tillers, etc. It is equipped with two heat activated sprinklers on the ceiling. I am concerned that brewing near one of these may trigger a catastrophic dilution of the mash or wort. I plan to place my setup away from an area directly under one of the sprinklers and point a portable fan to blow on the sprinkler trying to keep the heat away.

Has anyone had experience in this type of situation or know more about the tolerances of these sprinklers?
