How do sprinkler systems work?
These pipes wind through the building and outside to connect with a reliable water source. When the sprinkler head is triggered, a valve to the pipe system is opened, releasing the water that is kept under pressure from the pipes. The water is quickly pushed out of the pipes through the sprinkler head, spraying water downward and out to the sides.
How do sprinkler systems detect a fire?
Sprinkler systems detect a fire through rising temperatures. As the temperature at the sprinkler head rises to between 135 to 165 degrees Fahrenheit, the liquid inside the glass bulb expands and breaks the glass, thus activating the sprinkler head.
What triggers fire sprinkler systems?
Fire sprinkler systems are triggered by extreme heat and can quickly extinguish a fire in the room where it started. You've probably seen a number of movies where a small amount of smoke triggers all of the sprinklers in a building, soaking everyone and everything inside.
How effective are sprinkler systems in preventing fires?
But today, sprinkler systems are credited with reducing deaths and loss of property by more than 65 percent [source: Fleming ]. Since each sprinkler head is automatically triggered by fire-specific temperature, just one or two sprinklers can quickly extinguish and/or contain a fire to the room where it started and cause little property damage.
What makes apartment sprinklers go off?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction.
Do apartment sprinklers detect smoke?
No, Smoke Won't Trigger Fire Sprinklers The simple fact of the matter is: smoke will never set off a fire sprinkler system. The purpose of fire sprinklers is to save property and life from an actual, full-burning fire. It is not an early warning system, such as a smoke detector.
How does a building sprinkler system work?
The typical sprinkler head consists of a plug held in place by a trigger mechanism. The most common type of trigger is a glass ampule filled with a glycerin-based liquid that expands when heated. 155º As soon as the trigger mechanism is heated to the required temperature, it trips and the water is released.
How do I clean my apartment sprinklers?
Clean-up is simple, as well. All you need is warm water to rinse the SprinklerVac and a soft cloth to dry it. It really is the best option for cleaning fire sprinkler heads. Avoid spending an immense amount of effort and money replacing dirty sprinklers, or risking a burst-bulb using compressed air.
Will vaping set off a sprinkler system?
Rest assured that while there's a small possibility of triggering a fire alarm by smoking or vaping, there's no chance of setting off the fire sprinklers. Contrary to popular belief, sprinkler heads are triggered by heat, not smoke or vapor.
Can cigarette trigger sprinklers?
While there's a small chance of setting off your fire alarm while smoking, vaping, cooking, or burning candles or incense, rest assured that these items won't set off the fire sprinklers. The only exception to this statement is if you hold a lighter or candle flame directly up to a sprinkler head.
Do all sprinklers go off at once?
Typically, the answer is no. However, there is one type of system where all sprinklers will release water simultaneously. This system is called a deluge fire sprinkler system and is fairly uncommon.
Do fire sprinklers turn off automatically?
Smoke detectors activate fire sprinklers. Fire sprinklers will shut off automatically once a fire is under control.
Do sprinklers turn off automatically?
Nowadays, most sprinkler systems are equipped with a rain and freeze sensor that senses precipitation events and freezing temperatures and automatically turns off the sprinkler so that it does not water.
How do you turn off fire sprinklers in an apartment?
When fire sprinklers activate unintentionally (or when they work as intended), you basically have two options to stop the water: turn off a control valve or use fire sprinkler tools—a sprinkler stopper like the Shutgun—to stop the flow at an activated sprinkler.
How often do sprinklers need to be serviced?
How often should sprinkler systems be inspected? Due to the importance of service and maintenance, an annual service is a requirement, and has been documented in the BS EN 12845 where it states that: "The sprinkler system should be periodically inspected at least once a year by a third party."
How often should sprinkler heads be cleaned?
That way, you can eliminate the possibility of clogged sprinkler heads or trapped debris causing problems. Sprinkler systems should be cleaned at least twice a year. It's especially important to get rid of clogs before storing your system for the winter, so schedule your two cleanings for late fall and late spring.
How do I test my apartment for smoke detectors?
Press and hold the test button on the smoke detector. It can take a few seconds to begin, but a loud, ear-piercing siren should emanate from the smoke detector while the button is pressed. If the sound is weak or nonexistent, replace your batteries.
Do fire alarms detect cigarette smoke?
Yes they can. That being said it takes a good amount of smoke in an area to set off most detectors. If you smoke one cigarette in a larger room and aren't close to the detector it probably won't set it off. On a semi-related topic it is definitely recommended to keep smoking outside of a building, including your home.
Can water trigger smoke alarms?
Dense water vapor is like humidity when it comes to triggering false alarms. When you take a shower or boil water on the stove, smoke detectors can sense the steam and sound the alarm. Make sure you ventilate your bathroom and kitchen properly to prevent this.
How sensitive is a smoke detector?
How Sensitive Is a Fire Alarm? The photoelectric types of smoke detectors are very sensitive to the fuming fire that emits large-sized smoke particles. On the other hand, ionization smoke alarms are sensitive to the flames fire that emits small-sized smoke particles.
What temperature will set off a fire sprinkler?

In case of a fire, these systems are 91 percent effective in putting out a common house fire.
How many types of fire sprinkler systems are there?
There are four types of fire sprinkler systems: upright, concealed, pendent and sidewall.
How does a sprinkler system work?
Depending on the type of sprinkler system, the method of sprinkler activation can vary. Once the glass bulb breaks, the sprinkler head releases water. However, the way water is stored and is delivered through pipes depends on the type of fire sprinkler system. Wet pipe systems store water in the pipes and release it immediately when the trigger breaks. Dry pipe systems store water behind a valve that needs to be released before the water can flow through the pipes and out of the sprinkler head. A pre-action sprinkler is like a dry pipe system except for the valve is controlled by an electronic device. The only exception is the deluge sprinkler system that is not activated by heat at all. Instead, a fire alarm releases the water and a valve must be manually closed to stop the flow of water.
Why are sprinklers important?
Sprinkler systems are an important part of protection from fires. A fire sprinkler system can prevent property damage and reduce the risk of injury to workers, customers, or tenants. But how exactly does a fire sprinkler system work?
What is a deluge sprinkler system?
Deluge sprinkler systems release water from every sprinkler head once a fire alarm goes off and are used in facilities with flammable or combustible liquids where the threat of fire is extremely high. Keystone Fire Protection Co. offers a foam sprinkler system for these high-risk environments which smothers, cools, and extinguishes fires.
How does a wet pipe system work?
Wet pipe systems store water in the pipes and release it immediately when the trigger breaks. Dry pipe systems store water behind a valve that needs to be released before the water can flow through the pipes and out of the sprinkler head. A pre-action sprinkler is like a dry pipe system except for the valve is controlled by an electronic device.
What temperature does a sprinkler head need to be?
As the temperature at the sprinkler head rises to between 135 to 165 degrees Fahrenheit, the liquid inside the glass bulb expands and breaks the glass, thus activating the sprinkler head. There are various colors of liquid in these glass components, each indicating a different threshold of heat required to break the glass.
Can a sprinkler system be activated by heat?
The only exception is the deluge sprinkler system that is not activated by heat at all. Instead, a fire alarm releases the water and a valve must be manually closed to stop the flow of water.
Does a fire sprinkler system clean up?
Other fire sprinkler systems have minimal clean-up and cause little damage due to the localized response such as the Hi-Fog Water Mist system offered by Keystone Fire Protection Co.
What Sets Off A Sprinkler System?
Fire sprinkler systems are crucial for protecting buildings from fires as they are active systems, and are ready to go off when triggered. Typically, the system is activated when the air around it reaches 155 degrees or higher.
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.

Why is a fire sprinkler system important?
About Fire Sprinkler Systems! No matter if you are looking to protect a recent commercial addition or an entire office building, installing a fire sprinkler system is an important step in reducing fire risks and supporting your safety.
What Triggers a Fire Sprinkler System?
Typically, fire sprinklers are triggered when the surrounding air temperature is no less than 155 degrees Fahrenheit. At this temperature and above, they react very fast to extinguish the fire below. They are also effective at limiting the development of toxic smoke while firefighters make their way to the scene.
What does a fire sprinkler look like?
When you install a fire sprinkler system in your property, you’d be right to think that each individual fire sprinkler looks like the head of a faucet. Similar to a faucet, fire sprinkler systems contain a series of pipes that contain pressurized water. Inside the sprinkler head is a small heat-sensitive plug. ...
Do fire sprinklers go off at the same time?
Whatever the case, what you’ve seen in the movies, should stay in the movies! Most are relieved to know that the majority of fire sprinkler systems today are triggered by heat, NOT smoke, and they won’t all go off at the same time.
Do fire sprinklers have heat detectors?
Thankfully, your average fire sprinkler is built with an individual heat detector, which means it has to be triggered on its own, regardless of what is happening with other sprinklers close by. For homeowners everywhere, that means your chances of experiencing a spontaneous indoor rainstorm are rare at best!
How do sprinklers work?
So how do garden sprinklers work using this water? When the unit is switched on, a valve is opened. Water is then pulled through the pipes and distributed across your lawn through spigots. It’s the same method used to provide water through a tap, just with a few more pipes and spigots.
Where are sprinkler heads installed?
These are the spigots that distribute the water. They will be installed centrally in the sprinkler ones in your yard. It’s important to routinely inspect these heads for damage or blockages, as they could cause uneven distribution.
What is zone line in sprinkler system?
These pipes define the zone lines of your sprinkler system, meaning that they are laid out to cover the area that needs watering perfectly.
How deep are the pipes in a lawn water system?
The pipes are typically buried 6-12 inches beneath your lawn. This is partially why installing the unit yourself is not always a good idea: a neat installation isn’t as easy as it sounds. Lawn care is as much about not tearing the lawn up as keeping it watered!
What is irrigation system?
Irrigation refers to the network of pipes that channel water around your yard. They are connected to a primary water source used for other applications in your area, which is why the backflow preventer is so important. You don’t want water that may have had contact with soil or been sitting stagnant in pipes running into the local drinking water supply.
What is a shut off valve?
The main shut-off valve fully cuts off the water being fed to the unit. This is an essential safety device in the case of leaking pipes. If a pipe is leaking and water continues to seep through, it could cause damage to your lawn. The shut-off valves in additional pipes can be used to prevent water from flowing to a certain zone, which means that you can address leaky pipes locally instead of shutting down the whole unit.
What is the goal of a water disperser unit?
The goal of the unit is to disperse water evenly across your yard to keep your lawn healthy. This means:
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.
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.
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.
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.
Overview
Fire Sprinklers are a life safety device that many people may have heard about, but don’t know how they work. Fire Sprinklers are essential to protect you and others when living in an apartment. When you live in an apartment you are wall to wall with a neighbor.
Common mistakes
One thing we hear a lot when inspecting apartment units is that when we open a bathroom or closet door the occupant says “There is no sprinkler in there”. Many times this is true, but not all the time. The determining factor is the size of the room or closet. You would be surprised how many people never noticed the sprinkler head in their closet.
What to look for
When you are living in an apartment you want to make sure the entire complex is being inspected annually at a minimum. This way you can feel comfortable that your neighbor hasn’t done anything to prevent the fire sprinklers from working.
Choosing an Inspector
When you are choosing a company to inspect your fire sprinkler system, you need to make sure they have all of the proper licenses, insurance, and qualified technicians. Most companies are good and genuinely care.
Conclusion
Testing and Inspections are extremely important. If the City or Insurance company forgets to ask you for it, don’t say to your self we just saved a bunch of money. You didn’t as it may come back to haunt you one day.
How Do Rotating Sprinklers Work?
Once the in-ground home sprinkler system is activated, water travels through the PVC pipes and is released through the rotating sprinklers. The sprinklers rotate to give an even spread of water over the chosen area.
Why do sprinkler heads swing joints?
Swing joints are adjustable to ensure the sprinkler heads are not above the soil surface, which could cause damage to mowers. Sprinkler heads deliver the water from the PVC to the lawn and come in a variety of shapes and sizes. The lawn can then be divided into zones, which are a collection of sprinklers that cover a specific area of the lawn.
What is the best way to water a lawn?
Out of all the options available for watering your lawn, an automatic irrigation system is the most efficient. Sprinklers can be precisely adjusted to water only the turfgrass and avoid watering areas like concrete driveways, and also to help prevent overwatering a lawn. A watering schedule can be programmed to the systems and no further action is needed! (Set it and forget it). These schedules can be easily adjusted based on the time of the season, and recent improvements can allow you to adjust your sprinkler system from your smartphone using a Smart Controller. This ability to control your sprinkler remotely makes a great deal of difference for those who lead busy working and family lives.
When do sprinklers turn off?
Sprinkler systems are programmed to run at a specific time of day, usually early in the morning. The sprinklers do not turn on until they receive an electronic signal from the control box. Once the signal reaches the sprinklers, they run for a designated period of time and turn off automatically. You can interrupt the pre-programmed settings and turn off the sprinklers remotely using a smartphone app or when certain rain is in the forecast.
Do sprinklers save money?
After the initial investment of the in-ground sprinkler system installation, the benefits will continue for the life of the system. If you are wanting a lush green lawn throughout the year, an automatic sprinkler system not only saves you money in the long run, but also frees up your time to enable you to get on with your daily life.

Pressurized Sprinkling
- Wet pipe, dry pipe, and pre-action sprinklers all use pressurized air. In wet pipe sprinklers, pressure in the pipes ensures the water is delivered quickly. In dry pipe and pre-action sprinkler systems, pressurized air is used to fill the pipes instead of water filling the pipes. Once the air is released, due to a fire being detected, the water then flows through the pipes.
Post Fire
- It is a myth that once a fire is detected all fire sprinklers go off. fire sprinkler system detects rising temperatures at each individual sprinkler head and goes off only when the fire reaches that sprinkler. If you require a sprinkler system where all the sprinkler heads go off at the same time, then you need a deluge sprinkler system. Deluge sprinkler systems release water from every spri…
Fire Sprinkler System Maintenance, Testing, and Inspection
- Fire sprinkler systems should be inspected and tested according to NFPA 25. Weekly or monthly, gauges should be inspected. Quarterly, alarm devices and control valves should be inspected. Bracings, pipes, fittings, and signings should be inspected annually. Every five years, an internal inspection is required. Tests of mechanical devices should happen quarterly. Switch type device…
