It caused the valve and its seat to move outwards simultaneously until the solder joint was completely severed. [13], Fire sprinklers can be automatic or open orifice. Most manufacturers, for example, offer corrosion-resistant PTFE (ENT) coatings. Contrary to motion picture representation, the entire sprinkler system does not activate at the same time, unless the system is a special deluge type.[14][15]. Licensed fire sprinkler designers and installers are key to ensuring that the sprinkler type, location, and temperature are customized to the fire hazard, occupancy type, and architectural design of a structure. When these heads are activated, a stream of water is sent downward onto the deflector, which disperses the water throughout the room. The response time is expressed as a response time index (RTI), which typically has values between 35 and 250 m½s½, where a low value indicates a fast response. Pendent heads feature a convex, almost umbrella-shaped deflector that guides water out and away from the sprinkler head when properly installed. The frame at the core of each fire sprinkler is manufactured in a process called metal casting, where liquid metal takes shape as it cools inside a hollow mold. By this means, the valve seat was forced against the valve by the water pressure, producing a self-closing action. Residential occupancies are provided with a special type of fast response sprinkler with the unique goal of life safety (a residential sprinkler has a higher discharge pattern than that of a standard spray sprinkler and they also have been specifically developed for discharging water higher on the walls in order to keep ceiling gas temperatures lower).[16][17]. 3/4″ sprinklers, on the other hand, are used when larger quantities of water are necessary. Fusible link fire sprinklers replace that bulb with metal components secured to the sprinkler by a heat-sensitive alloy. Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb (see below) or a two-part metal link held together with a fusible alloy such as Wood's metal[21] and other alloys with similar compositions. A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded.
