![]() Due to its provision of maximum coverage, the sprinkler is ideal for offices, homes etc.Ģ) Concealed Pendent Heads – Sprinkler heads that are concealed are totally covered by a cover plate, whereas sprinkler heads that are recessed are exposed and surrounded by a disc-shaped escutcheon. The water is sprayed downwards to maximize the fire affected area. These water sprinklers are hung from the ceilings towards the ground. ![]() Deflectors on upright heads, on the other hand, bend toward the piping, capturing and redistributing water as it shoots up toward the ceiling. There are many types of water sprinkler heads which can be used according to one’s use-ġ) Pendent Sprinkler Heads – When properly fitted, pendent heads have a convex, almost umbrella-shaped deflector that guides water out and away from the sprinkler head. This increases water pressure on the fire’s source and reduces water damage to the structure. As a result, only the sprinklers closest to the fire will activate, usually only one or two. When the predetermined heat level is attained in a conventional wet-pipe sprinkler system, each sprinkler operates independently. The glass bulb or link exerts pressure on a pipe cap, which functions as a stopper, preventing water from flowing until the ambient temperature around the sprinkler meets the individual sprinkler head’s design activation temperature. Sprinkler systems are widely utilised around the world, with more than 40 million sprinkler heads installed each year.Ī heat-sensitive glass bulb or a two-part metal link held together with fusible alloy keeps each closed-head sprinkler closed. Systems for homes and small buildings, which were previously only available in factories and large commercial structures, are now available at a cost-effective price. A fire sprinkler system is an active fire prevention method that consists of a water supply system that delivers sufficient pressure and flowrate to a water distribution piping system, which is coupled to fire sprinklers.
