SPRINKLER SYSTEM
Fire Sprinkler Signs- The signs are design to identify different controls and pipes for fire sprinkler systems in your facility. 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. Many state required owners to install clear signs of what type of fire sprinkler he has on his facility.
Sprinkler system :A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system, onto which fire sprinklers are Types
Wet pipe systems: 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.
Wet pipe antifreeze: Wet systems may be charged with an antifreeze chemical, for use where pipes can't reliably be kept above 40 °F (4 °C).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.
Dry pipe systems: 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
Deluge systems: "Deluge" systems are systems in which all sprinklers connected to the water piping system are open, in that the heat sensing operating element is removed, or specifically designed as such. 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
Pre-action systems: 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.
Electronic sprinkler systems: Electronic sprinkler systems are systems comprising sprinklers in which the heat sensing operating element is replaced by electronic sensing and electronically triggered actuation. Sprinkler operation is often controlled via an algorithm that determines which sprinklers will operate and when. These systems are often used in scenarios that require fast response and controlled sprinkler operations, such as high-ceiling pallet racking storage with fast-burning commodities or dense storage applications.
Foam water sprinkler systems: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.
Water spray system: "Water spray" systems are operationally identical to a deluge system, but the piping and discharge nozzle spray patterns are designed to protect a uniquely configured hazard, usually being three-dimensional components or equipment. 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
There are various types of fire sprinkler systems below you will find 4 type of fire system that people most used:
Dry Pipe Sprinkler system-Dry pipe sprinklers are similar to pre-action systems as they use pressurized air in the pipe which exits before water escapes. This causes a minute delay in water discharge but is ideal for buildings with low temperatures so the pipes do not freeze. These fire sprinkler systems have a fast opening tool to get rid of the air and speed up the flow of water. Warehouses located in the north are a good example of what buildings should use dry pipe sprinklers.
Wet Pipe Sprinkler system-Wet pipe fire sprinklers constantly have water in them. This allows for a quick reaction to a fire and is the most common type of sprinkler installed in buildings. A type of building that uses the wet pipe system is a high-rise or office building with a few floors. This fire sprinkler system is cost efficient and low maintenance.
Pre-action fire sprinkler system-Pre-action fire sprinkler systems are filled with air and water is allowed to pass through when the smoke alarm or detector goes off. This type of system requires two triggers to start water flow. It helps greatly that the pre-action fire sprinkler can be set to prevent water from spouting in case of a false alarm or a mechanical failure. The pre-action system is good for use in places where the sprinklers are only necessary when there is an actual fire so other items in the building do not get water damage from an accidental sprinkling. Such buildings include libraries and data centers. These places contain items of high value like electronics and goods damageable by water such as books
Deluge Fire Sprinkler -These types of fire sprinkler systems also need a smoke or heat detector like the pre-action system. A deluge system has open nozzles that can be used when a hazard is present. When flammable liquids are spread across a floor, deluge fire sprinklers are good to have. In that case, buildings such as industrial parks and buildings with many tanks have deluge fire sprinkler systems installed.
