How do sprinklers function during a fire?
Sprinklers activate in the specific area that they detect the rising heat from a fire. This means very little water damage occurs because of how quickly sprinklers can deploy. Sprinklers can also minimize water damage, as they cover a larger area with less than 20% the water that would be needed by a fire hose in the same situation.

What is sprinkler pipework?
The pipework is specially designed to ensure the correct flow and pressure of water which is maintained at each sprinkler head. The water supply to the system can be fed from the water supply provided by the state water authority. For light to medium fire risks such as residential, offices, hotels, and light manufacturing and commercial occupancies a pumped supply from a water storage tank or reservoir is normally necessary for high fire risk areas such as heavy manufacturing and warehouse storage. The international design requirements are specified in the British standard BS v 306 part 2 and LPC FM or NFPA design rules. The flow of water to the sprinkler heads is automatically delivered by a control and alarm valves.
What is sidewall sprinkler?
Sidewall sprinklers are generally used to keep ceilings clear of pipework or to avoid having to disorder the existing ceilings while installing. In light hazards, each sprinkler protects up to 17 square meters of fire risks and protect up to nine square meters of fire risks during ordinary hazards. Sidewall sprinklers are specifically designed to give an extended coverage of water distribution with one sprinkler able to safeguard an area up to 21 square meters. Sprinklers must have a quick response bulb, to perform effectively.
How do sprinklers explode?
Sprinklers will explode when it’s rated temperature is reached due to fire, once it is activated it will discharge water and operate a local fire alarm. It can also operate a remote alarm to the emergency rescue team and the fire and rescue department. A typical sprinkler head consists of a threaded body to connect to pipework, with a valve seal to hold back the water. The valve seal is occupied by a glass bulb that contains a glass bulb filled with a glycerin-based liquid that has a high coefficient of expansion. A small measured volume of vapor remains trapped when the bulb is completely sealed.
How does a sprinkler bulb work?
When the liquid enlarges under the effect of heat from a fire, pressure in the bulb rises until the vapor is compressed. The further rise in temperature creates a rapid buildup of pressure sufficient to shatter the bulb and release the valve seal and allow the water to flow onto a water distribution deflector. This results in an even distribution of water droplets in a pre-arranged pattern over the fire. Operating temperatures of a variety of sprinkler’s heads are identified by the color of the bulb. A very large array of sprinkler heads are available to the specifiers.
What is a wet and dry sprinkler system?
Both the wet and dry system as the name suggests allows the system pipework is allowed to charge with water in summer and with air in winter when there is a risk that the room temperature can fall below freezing point. The pre-action system includes a standard sprinkler system and an independent electrical system of heat or smoke detectors installed in the same areas as of the sprinklers. The main control panel automatically opens the control valve when the signals received into the detectors and allowing water to flow into the sprinkler pipework. When the individual sprinkler heads reach their operating temperature, the water is released automatically.
Why do sprinklers need different valves?
All these types of sprinkler systems require different valve arrangements. A wet system usually protects places where the temperature does not fall below the freezing point. Because it helps to permanently charge water inside the pipe. On the other hand, a dry system is installed, where the pipework is charged with compressed air if static water is not available.
Why are sprinklers so effective?
The reason sprinklers are so effective is because it set OFF the fire before it has time to grow and spread without any excessive use of water. Most of the major countries have rescued from fire hazards by using fire sprinklers to good effect. The fire sprinklers are unique, not only detect a fire and raise an alarm but also operate to control and extinguish the fire in many cases before the arrival of the fire brigade.
Why are fire sprinklers effective?
Fire sprinklers are effective in extinguishing or containing fire because they react fast after a fire breaks out. They reduce the risk of injury and death because they reduce the flames, heat and smoke of a fire . Fire sprinkler systems give people the time needed to evacuate the building. They reduce property damage because they contain or extinguish the fire before the fire department arrives. Fire sprinklers are one of the best tools we have to fight fires.
What does a sprinkler do?
The sprinkler sprays water on the fire. Sometimes the fire is completely extinguished. Sometimes the sprinkler contains the fire, meaning it controls the heat and minimizes the amount of toxic smoke that develops.
How much water does a fire sprinkler discharge?
The amount of water discharged by a fire sprinkler is minimal (10-15 gallons per minute). If this was not the case, we’d be trading fire damage with water damage. But that is not how a fire sprinkler works.

Does Every Sprinkler Head Activate?
Since fire sprinkler systems are triggered by heat and not smoke, the entire system won’t go off at the same time. This is good news for small fires in large commercial buildings, as property owners don’t want the whole floor or building getting wet when the fire is contained to one room and can be put out quickly.
Inspection and Maintenance
Fire sprinkler systems are found in various buildings, from retail stores to apartment buildings. They are a crucial part of a building’s fire protection system, and are one of the best resources for putting a fire out- if they are maintained and inspected regularly.

What is a fire sprinkler?
Fire sprinklers are very simple. The sprinkler is just a plug that holds back water in a pipe similar to your other plumbing pipes. Heat from a fire will break a glass tube or melt a solder plug which releases the water.
How are Fire Sprinklers Activated?
Contrary to popular misconceptions, automatic sprinklers are not activated by smoke. Sprinklers contain a heat sensitive element to trigger activation. In typical modern units, this is commonly a glycerine-based liquid in a glass bulb. This element is perfectly calibrated so that it will shatter at a specific temperature - usually between 135 and 165 degrees Fahrenheit. This element is unique to each sprinkler, meaning that not all sprinklers in a system need to be activated at the same time.
What is dry pipe?
Dry pipe systems fill pipes between sprinkler heads with pressurized gas, keeping water in a reservoir. Once a sprinkler head activates in response to a fire, the gas escapes the system and water floods the pipes and douses the fire.
What is a wet pipe system?
Wet pipe systems are straightforward and effective systems. These sprinkler systems store pressurized water in pipes between sprinkler heads, ready to deploy when heat is detected. These systems are very common and can be easy to maintain relative to more complex designs. Water is pressurized at the sprinkler head, so it is impossible for other systems to compete with the speed at which a wet pipe system can act to douse a fire.
Why is a fire sprinkler system important?
Properly maintaining a fire sprinkler system is essential to ensure that it operates perfectly when it’s needed.
Why are sprinklers false?
Another commonly held false belief about sprinklers is that they will create serious water damage in place of fire damage. Sprinklers activate in the specific area that they detect the rising heat from a fire. This means very little water damage occurs because of how quickly sprinklers can deploy.
How often should a fire alarm system be inspected?
Every five years, a system should be thoroughly inspected in extreme detail, and any necessary preventative maintenance taken. These inspections should be conducted by a fire and life safety company to ensure everything is in working order and up to code.
Can a sprinkler head be pressurized?
Water is pressurized at the sprinkler head, so it is impossible for other systems to compete with the speed at which a wet pipe system can act to douse a fire. While wet pipe systems can be more affordable and accessible, they can be risky if not properly maintained to prevent leaking and potential flooding.
