I grew up in a rural community that had sprinkler systems in the school like this. Very rural and very outdated.
Although there are automatic fire sprinkler systems that perform as described, they are not likely to be found in a school building. The typical system will only function if it gets exposed to enough heat and I would surmise that in a school building the temperature settings for the ceiling sprinklers would be about 135 deg. F.
