Fire sprinkler - Wikipedia. This article is about the device discharging the water. For the complete system, see fire sprinkler system. Fire sprinklers are extensively used worldwide, with over 4. In buildings protected by properly designed and maintained fire sprinklers, over 9. When someone noticed a fire, a valve outside the building could be opened to send water through the pipes. As a result, Maxim invented the first automatic fire sprinkler. It would douse the areas that were on fire, and it would report the fire to the fire station. Maxim was unable to sell the idea elsewhere, but when the patent expired the idea was used. Parmalee of New Haven, Connecticut created and installed the first automatic fire sprinkler system in 1. At the time he was the president of Mathusek Piano Works. Parmelee invented his sprinkler system in response to exorbitantly high insurance rates. Parmalee patented his idea and had great success with it in the U. S. Parmalee called his invention the . Most people could not afford to install a sprinkler system. Once Parmalee realized this, he turned his efforts on educating the insurance companies about his system. He talked about how the sprinkler system would reduce the loss ratio, thus saving money for the insurance companies. He knew that he could never succeed in obtaining contracts from the business owners to install his system unless he could ensure for them a reasonable return in the form of reduced premiums. In this connection he was fortunate enough to enlist the sympathies of two men, who both had connections in the insurance industry. The first of these was Major Hesketh, who, in addition to being a cotton spinner in a large business in Bolton, was Chairman of the Bolton Cotton Trades Mutual Insurance Company. The Directors of this Company and more particularly its Secretary, Peter Kevan, took an interest in Parmalee. Hesketh got Parmalee his first order for sprinkler installations in the cotton spinning mills of John Stones & Company, at Astley Bridge, Bolton, followed soon afterwards by an order from the Alexandra Mills, owned by John Butler of the same town. Although Parmalee got two sales through its efforts, the Bolton Cotton Trades Mutual Insurance Company was not a very big company outside of its local area. Parmalee needed a wider influence. He found this influence in James North Lane, the Manager of the Mutual Fire Insurance Corporation of Manchester. This company was founded in 1. Textile Manufacturers' Associations of Lancashire and Yorkshire as a protest against high insurance rates. They had a policy of encouraging risk management and more particularly the use of the most up- to- date and scientific apparatus for extinguishing fires. Even though he put tremendous effort and time into educating the masses on his sprinkler system, by 1. Parmalee sprinkler. Back in the U. S., Frederick Grinnell, who was manufacturing the Parmalee sprinkler, designed the more effective Grinnell sprinkler. He increased sensitivity by removing the fusible joint from all contact with the water, and, by seating a valve in the center of a flexible diaphragm, he relieved the low- fusing soldered joint of the strain of water pressure. By this means the valve seat was forced against the valve by the water pressure, producing a self- closing action, so that the greater the water pressure, the tighter the valve. The flexible diaphragm had a further and most important function. It caused the valve and its seat to move outwards simultaneously until the solder joint was completely severed. Grinnell got a patent for his version of the sprinkler system. He also took his invention to Europe, where it was a much bigger success than the Parmalee version. Eventually, the Parmalee system was withdrawn, which left an open path for Grinnell and his invention. Automatic fire sprinklers operate at a predetermined temperature, utilizing a fusible element, a portion of which melts, or a frangible glass bulb containing liquid which breaks, allowing the plug in the orifice to be pushed out of the orifice by the water pressure in the fire sprinkler piping, resulting in water flow from the orifice. The water stream impacts a deflector, which produces a specific spray pattern designed in support of the goals of the sprinkler type (i. Modern sprinkler heads are designed to direct spray downwards. Spray nozzles are available to provide spray in various directions and patterns. The majority of automatic fire sprinklers operate individually in a fire. Contrary to motion picture representation, the entire sprinkler system does not activate, unless the system is a special deluge type. Open orifice sprinklers are only used in water spray systems or deluge sprinklers systems. They are identical to the automatic sprinkler on which they are based, with the heat sensitive operating element removed. Automatic fire sprinklers utilizing frangible bulbs follow a standardized color- coding convention indicating their operating temperature. Activation temperatures correspond to the type of hazard against which the sprinkler system protects. Residential occupancies are provided with a special type of fast response sprinkler with the unique goal of life safety. Quick Response Sprinklers. The term quick response refers to the listing of the entire sprinkler (including spacing, density and location) not just the fast responding releasing element. Many standard response sprinklers, such as extended coverage ordinary hazard (ECOH) sprinklers, have fast responding (low thermal mass elements) in order to pass their fire tests. Quick response sprinklers are available with standard spray deflectors, but they are also available with extended coverage deflectors. Because each sprinkler activates independently when the predetermined heat level is reached, the number of sprinklers that operate is limited to only those near the fire, thereby maximizing the available water pressure over the point of fire origin. The bulb breaks as a result of the thermal expansion of the liquid inside the bulb. Below the design temperature, it does not break, and above the design temperature it breaks, taking less time to break as temperature increases above the design threshold. The response time is expressed as a response time index (RTI), which typically has values between 3. The sensitivity of a sprinkler can be negatively affected if the thermal element has been painted.

Prior to the introduction of these sprinklers, protection systems were designed to control fires until the arrival of the fire department. Unwanted alarms. Slowly open the water supply valve, let the water flow out of the valves until it is flowing smoothly. This will prevent air from entering the system and help bleed any trapped air out of the system. This condition can be minimized by opening the remote inspector. The water flow device includes a retard or delay setting built into the switch, preventing the signal from being sent until the paddle is held forward, by water flow, for a set length of time.
