> I’ve lived through many cases of the sprinklers being set off accidentally (frozen pipe burst, rc-helicopter blade impact, and idiots using it as a clothes hook) and “some water” isn’t the phrase I would use. I think it’s more like if someone threw a bathtub from the ceiling every minute until someone could shut it off? That's why i specifically mentioned double-interlock preaction systems, where if someone hits the sprinkler and causes it to open, the only thing that comes out is compressed air (and a trouble/supervisory alarm sounds).
