When an area is subject to freezing temperatures, even for short periods, a wet system cannot be used. A dry system of automatic sprinklers is one in which the pipes normally contain air under pressure instead of water. It is designed so that when a sprinkler opens, the air escapes and water is admitted automatically by the operation of a dry pipe valve. After the valve operates, the entire sprinkler system operates just like a regular wet system.
