      dry PIPE SYSTEMS

      Dry pipe systems are used where extensive portions of the system are subject to freezing temperatures.
      In a dry pipe system, automatic fire sprinklers are attached to a piping system containing air under pressure. The release of the air from an opening sprinkler due to a fire permits the water pressure to open a dry pipe valve. The water then flows into the piping system and out the opening sprinklers.

      preaction SYSTEMS

      A preaction system is used where accidental discharge of water is a special concern.
      In the preaction system, automatic fire sprinklers are attached to a piping system containing air that may or may not be under pressure, with a supplemental detection system installed in the same area as the sprinklers. Actuation of the detection system opens a valve that permits water to flow into the sprinkler piping system and to be discharged from any sprinklers that are open.
      Variations of the preaction system are possible. In a non-interlocking preaction system, water is admitted to the sprinkler piping on operation of either the detection devices or automatic fire sprinklers. In the most common type of preaction system, the single interlock system, water is admitted to the sprinkler piping upon operation of the detection devices.
      In the double-interlock system, often used for protection of freezers, water is admitted to sprinkler piping only upon operation of both the detection devices and automatic fire sprinklers.
