A dry sprinkler system in which automatic devices charge the pipes before the individual heads open and begin to discharge the extinguishing agent.

CONT

Pre-action Systems: Pre-action systems are dry-pipe systems in which the air in the piping may or may not be under pressure. When a fire occurs, a supplementary fire detecting device in the protected area is actuated. This opens a valve which permits water to flow into the piping system before a sprinkler is activated. Then there is no further delay when a sprinkler is subsequently opened by the heat of the fire.

OBS

preaction sprinkler system; preaction system: terms officially approved by the Lexicon Project Committee (New Brunswick).
