A combination dry pipe/wet pipe system. The system exists as a dry pipe until the initial stages of a fire (smoke, heat, and so on) are detected and then the pipes are filled with water. The water is released only after the sprinkler head activation triggers are melted by sufficient heat. If the fire is quenched before the sprinklers are triggered, the pipes can be manually emptied and reset. This also allows for manual intervention to stop the release of water before sprinkler triggering occurs. Preaction systems are the most appropriate water-based system for environments that include both computers and humans in the same locations.
