A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Leonardo da Vinci designed a sprinkler system in the 15th century. Leonardo automated his patron's kitchen with a super-oven and a system of conveyor belts.

In a comedy of errors, everything went wrong during a huge banquet, and a fire broke out. Ambrose Godfrey created the first successful automated sprinkler system in The world's first modern recognizable sprinkler system was installed in the Theatre Royal, Drury Lane in the United Kingdom in by its architect, William Congreve , and was covered by patent No.

Frederick Grinnell improved Henry S. Parmalee 's design and in patented the automatic sprinkler that bears his name. Over the years, fire sprinklers have become mandatory safety equipment" [8] in some parts of North America, in certain occupancies , including, but not limited to newly constructed "hospitals, schools, hotels and other public buildings", [8] subject to the local building codes and enforcement.

However, outside of the US and Canada, sprinklers are rarely mandated by building codes for normal hazard occupancies which do not have large numbers of occupants e. Sprinklers are now commonly installed in other buildings including schools and residential premises.

Building regulations in Scotland and England require fire sprinkler systems to be installed in certain types of properties to ensure safety of occupants. In Scotland, all new schools are sprinkler protected, as are new care homes, sheltered housing and high rise flats. In Wales became the first country in the world to make installation of fire sprinklers in new homes mandatory.

The law applies to newly built houses and blocks of flats, as well as care homes and university halls of residence. This law came into force on September Sprinklers have been in use in the United States since , and were used in factory applications where fires at the turn of the century were often catastrophic in terms of both human and property losses.

Sprinklers may be required to be installed by building codes , or may be recommended by insurance companies to reduce potential property losses or business interruption. Building codes in the United States for places of assembly, generally over persons, and places with overnight sleeping accommodation such as hotels , nursing homes , dormitories , and hospitals usually require sprinklers either under local building codes, as a condition of receiving State and Federal funding or as a requirement to obtain certification essential for institutions who wish to train medical staff.

Building codes, which specify which buildings require sprinklers are generally left to local jurisdictions. However there are some exceptions:. The most visible of these conditions is the implementation of sprinklers. As more and more hotels and other public accommodations upgraded their facilities to enable acceptance of government visitors, this type of construction became the de facto industry norm — even when not directly mandated by any local building codes.

If building codes do not explicitly mandate the use of fire sprinklers, the code often makes it highly advantageous to install them as an optional system.

Most US building codes allow for less expensive construction materials, larger floor area limitations, longer egress paths, and fewer requirements for fire rated construction in structures protected by fire sprinklers.

Consequently, the total building cost is often decreased by installing a sprinkler system and saving money in the other aspects of the project, as compared to building a non-sprinklered structure. In , Pennsylvania and California became the first US states to require sprinkler systems in all new residential construction. Renewed interest in and support for sprinkler systems in the UK has resulted in sprinkler systems being more widely installed.

In schools, for example, the government has issued recommendations through Building Bulletin that most new schools should be constructed with sprinkler protection. In Wales became the first country in the world where sprinklers are compulsory in all new homes. In the UK, since the s sprinklers have gained recognition within the Building Regulations England and Wales and Scottish Building Standards and under certain circumstances, the presence of sprinkler systems is deemed to provide a form of alternative compliance to some parts of the codes.

For example, the presence of a sprinkler system will usually permit doubling of compartment sizes and increases in travel distances to fire exits as well as allowing a reduction in the fire rating of internal compartment walls.

In Norway as of July , all new housing of more than two storeys, all new hotels, care homes and hospitals must be sprinklered. Other Nordic countries require or soon will require [ citation needed ] sprinklers in new care homes, and in Finland as of a third of care homes were retrofitted with sprinklers.

A fire in an illegal immigrant detention center at Schiphol airport in The Netherlands on 27 October killed 11 detainees and led to the retrofitting of sprinklers in all similarly designed prisons in the Netherlands.

Most European countries also require sprinklers in shopping centers, in large warehouses and in high-rise buildings. Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb or a two-part metal link held together with fusible alloy. The glass bulb or link applies pressure to a pipe cap which acts as a plug which prevents water from flowing until the ambient temperature around the sprinkler reaches the design activation temperature of the individual sprinkler head.

In a standard wet-pipe sprinkler system, each sprinkler activates independently when the predetermined heat level is reached. Thus, only sprinklers near the fire will operate, normally just one or two. This maximizes water pressure over the point of fire origin, and minimizes water damage to the building. In addition, a sprinkler will usually activate within one to four minutes of the fire's start, whereas it typically takes at least five minutes for a fire department to register an alarm and drive to the fire site, and an additional ten minutes to set up equipment and apply hose streams to the fire.

This additional time can result in a much larger fire, requiring much more water to extinguish. By a wide margin, wet pipe sprinkler systems are installed more often than all other types of fire sprinkler systems.

They also are the most reliable, because they are simple, with the only operating components being the automatic sprinklers and commonly, but not always the automatic alarm check valve.

An automatic water supply provides water under pressure to the system piping. While such systems were once common in cold areas, after several fires caused by systems running too high a percentage of antifreeze, the regulatory authority in the United States effectively banned new antifreeze installations. A sunset date of applies to older antifreeze systems in the USA. Dry pipe systems are the second most common sprinkler system type.

Dry pipe systems are installed in spaces in which the ambient temperature may be cold enough to freeze the water in a wet pipe system, rendering the system inoperable. Dry pipe systems are most often used in unheated buildings, in parking garages, in outside canopies attached to heated buildings in which a wet pipe system would be provided , or in refrigerated coolers.

Water is not present in the piping until the system operates; instead, the piping is filled with air at a pressure below the water supply pressure. To prevent the larger water supply pressure from prematurely forcing water into the piping, the design of the dry pipe valve a specialized type of check valve results in a greater force on top of the check valve clapper by the use of a larger valve clapper area exposed to the piping air pressure, as compared to the higher water pressure but smaller clapper surface area.

When one or more of the automatic sprinkler heads is triggered, it opens allowing the air in the piping to vent from that sprinkler. Each sprinkler operates independently, as its temperature rises above its triggering threshold.

As the air pressure in the piping drops, the pressure differential across the dry pipe valve changes, allowing water to enter the piping system. Water flow from sprinklers, needed to control the fire, is delayed until the air is vented from the sprinklers. In regions using NFPA 13 regulations, the time it takes water to reach the hydraulically remote sprinkler from the time that sprinkler is activated is limited to a maximum of 60 seconds.

In industry practice, this is known as the "Maximum Time of Water Delivery". The maximum time of water delivery may be required to be reduced, depending on the hazard classification of the area protected by the sprinkler system. Some property owners and building occupants may view dry pipe sprinklers as advantageous for protection of valuable collections and other water sensitive areas.

This perceived benefit is due to a fear that wet system piping may slowly leak water without attracting notice, while dry pipe systems may not fail in this manner. These systems are used for special hazards where rapid fire spread is a concern, as they provide a simultaneous application of water over the entire hazard.

They are sometimes installed in personnel egress paths or building openings to slow travel of fire e. Water is not present in the piping until the system operates. Because the sprinkler orifices are open, the piping is at atmospheric pressure. To prevent the water supply pressure from forcing water into the piping, a "deluge valve" is used in the water supply connection, which is a mechanically latched valve.

It is a non-resetting valve, and stays open once tripped. Because the heat sensing elements present in the automatic sprinklers have been removed resulting in open sprinklers , the deluge valve must be opened as signaled by a fire alarm system.

The type of fire alarm initiating device is selected mainly based on the hazard e. The initiation device signals the fire alarm panel, which in turn signals the deluge valve to open. Activation can also be manual, depending on the system goals. Manual activation is usually via an electric or pneumatic fire alarm pull station, which signals the fire alarm panel, which in turn signals the deluge valve to open.

Operation - Activation of a fire alarm initiating device, or a manual pull station, signals the fire alarm panel, which in turn signals the deluge valve to open, allowing water to enter the piping system. Water flows from all sprinklers simultaneously.

Pre-action sprinkler systems are specialized for use in locations where accidental activation is especially undesirable, such as in museums with rare art works, manuscripts, or books; and data centers, for protection of computer equipment from accidental water discharge. Pre-action systems are hybrids of wet, dry, and deluge systems, depending on the exact system goal. There are two main sub-types of pre-action systems: single interlock, and double interlock.

The operation of single interlock systems are similar to dry systems except that these systems require that a "preceding" fire detection event, typically the activation of a heat or smoke detector, takes place prior to the "action" of water introduction into the system's piping by opening the pre-action valve, which is a mechanically latched valve i. In this way, the system is essentially converted from a dry system into a wet system.

The intent is to reduce the undesirable time delay of water delivery to sprinklers that is inherent in dry systems. Prior to fire detection, if the sprinkler operates, or the piping system develops a leak, loss of air pressure in the piping will activate a trouble alarm. In this case, the pre-action valve will not open due to loss of supervisory pressure, and water will not enter the piping.

The operation of double interlock systems are similar to deluge systems except that automatic sprinklers are used. These systems require that both a "preceding" fire detection event, typically the activation of a heat or smoke detector, and an automatic sprinkler operation take place prior to the "action" of water introduction into the system's piping. Activation of either the fire detectors alone, or sprinklers alone, without the concurrent operation of the other, will not allow water to enter the piping.

Because water does not enter the piping until a sprinkler operates, double interlock systems are considered as dry systems in terms of water delivery times, and similarly require a larger design area. A foam water fire sprinkler system is a special application system, discharging a mixture of water and low expansion foam concentrate, resulting in a foam spray from the sprinkler.

These systems are usually used with special hazards occupancies associated with high challenge fires, such as flammable liquids , and airport hangars. Operation is as described above, depending on the system type into which the foam is injected.

The nozzles used may not be listed fire sprinklers, and are usually selected for a specific spray pattern to conform to the three-dimensional nature of the hazard e. Examples of hazards protected by water spray systems are electrical transformers containing oil for cooling or turbo-generator bearings. Water spray systems can also be used externally on the surfaces of tanks containing flammable liquids or gases such as hydrogen.

Water mist systems are used for special applications in which it is decided that creating a heat absorbent vapor is the primary objective. This type of system is typically used where water damage may be a concern, or where water supplies are limited.

NFPA [17] defines water mist as a water spray with a droplet size of "less than microns at the minimum operation pressure of the discharge nozzle.

By creating a mist, an equal volume of water will create a larger total surface area exposed to the fire. The larger total surface area better facilitates the transfer of heat, thus allowing more water droplets to turn to steam more quickly.

The SIN is comprised of one or two letters followed by three or four numbers. This requirement was implemented as of January 1, Therefore, sprinklers manufactured prior to may not have this mark on them. The goal behind the use of the SIN is to ensure proper use of the sprinklers in the field.

Specifiers, design engineers, and layout technicians can check the proposed use of a sprinkler against its capabilities. In addition, the SIN can be used after a system has been installed to assist inspectors in determining if a system is adequate. On a long term basis the SIN can help with proper replacement sprinklers when they are necessary.

Previously, sprinkler markings were not especially helpful to anyone trying to identify the type of sprinkler with which they were dealing. The original concept of the SIN was to create a unified model numbering system to assist the end user and authorities with easy identification in the field.

However, this was soon realized to be impractical. The vast number of variations and the fact that the same product could have different classifications from different laboratories prohibited this concept from proceeding.

Every change in orifice size, response classification, distribution characteristic, and maximum working pressure must be identified by a separate model number. This system has not been established to create uniformity of model numbers among the manufacturers. The letters in the SIN represent the manufacturer of the sprinkler. Their one or two letter code must be registered with the International Fire Suppression Alliance at www.

Each manufacturer is permitted a maximum of two different letter designations. However, there are also limitations on the possible letter combinations. First, the letters are limited to the English alphabet. Also, there is a list of letter s shown in the table below that are prohibited due to conflicts with established acronyms relative to the fire sprinkler industry such as laboratories, K-factors, sprinkler orientations or hazards.

The three or four numbers are the model numbers and are set by the manufacturer themselves. Some manufacturers use each digit to represent a characteristic of the sprinkler, while others use it strictly as a cataloging number.
