One characteristic of a dry-pipe system is a delay in time between the opening of a sprinkler and the discharge of water, which may allow the fire to spread and more sprinklers to open. The delay is due to the time required to exhaust the air from the sprinkler piping. The difficulty may be partly overcome by installation of quick-opening devices which either increase the rate of discharge of air from the piping or accelerate opening of the dry valve when one or more sprinklers operate, depending upon the type of device used.

OBS

quick-opening device: term officially approved by the Lexicon Project Committee (New Brunswick).
