We are going to have a sprinkler system installed in our firehouse. the apparatus bay will be covered by a wet system. I am okay with it although some outside the department have expressed concern that it should be a dry system since if the doors were to get left open (accidentally) during a response the system could freeze. I don't see this as much of an issue since other plumbing would probably freeze first. We could always install low heat warning since the station is not staffed.
