The sprinklers operate at pre-determined temperatures to discharge water over the affected part of the area below, the flow of water through the alarm valve initiating a fire alarm. The classic use of the sprinkler is in the hot gas layer which forms beneath the ceiling of an enclosure in which a fire is developing. Each function is performed separately and one is independent of the other except insofar as early detection makes extinction easier because the fire has not grown large. It must first detect a fire, and must then provide an adequate distribution of water to control or extinguish it. 1 Main Elements of a Sprinkler InstallationĪ sprinkler has two functions to perform.
