Fire sprinklers are highly effective active systems against fires. Over 96% of fires in buildings are controlled by fire sprinklers alone. They’re affordable, effective and simple, which explains why every year over 40 million fire sprinkler heads are fitted in houses, large and small, factories and commercial buildings. In some countries these systems are mandatory in such places as hotels, factories, meeting places, schools, and museums. Let’s look how they work.
The essential components are a water supply system and a fire sprinkler head. The sprinkler head is made up of a plug, a liquid-filled glass bulb, a sprinkler, and a frame. When a fire starts, the temperature of the environment rises and the liquid in the glass bulb begins to expand. If the temperature continues to rise, the liquid expands so much that it breaks the glass. There’s then nothing left to stop the water and it begins to come out from the plug. When water hits the sprinkler, it’s spread over a larger area.
There are different types of glass bulb filled with different liquids and these are color-coded. Orange bulbs have an operational temperature of 57C/135F, red bulbs’ 68C/155F, yellow bulbs’ 79C/175F, green bulbs’ 93C/200F, blue bulbs’ 141C/286F, purple bulbs’ 182C/360F, and black bulbs’ 227C/440F.
Fire sprinkler systems operate in different ways as well. The type we’ve just explained is known as a wet pipe system and is the commonest in use. Each sprinkler head is activated independently and the main goal is to reduce water damage in the event of a false alarm.
Another type is the dry pipe system. In this, the pipes are filled with pressurized nitrogen, which is released if a fire activates the valves in the sprinkler head. The pipes then fill with water, which is discharged over the smoke or flames. Dry pipe systems are widely used in cold climates since there’s a high risk of frozen pipes preventing an emergency fire response
Pre-action systems are a kind of dry pipe sprinkler system that require two activation steps. When heat or smoke is detected, the pre-action valve opens and allow water into the pipes. Then, the sprinkler heads can be individually activated to release water over the fire. This two-step process enables facilities to shut off the system in case of a false alarm, protecting assets from water damage. Pre-action systems are especially useful in places where accidental discharge could lead to irreparable damage, such as in museums, libraries, and data centers.
Another type of system is the deluge sprinkler system, which also uses dry pipe technology. However, in this system, the sprinkler heads are always open. The sprinkler heads don’t have heat-sensing elements but, instead, are activated by external smoke or heat sensors. Once heat is detected, water fills the pipes and is released to all open sprinkler heads, creating a flooding effect across the entire area. This system is most often used in industries with flammable liquids, which pose the threat of rapidly-spreading fires.

Another thing is, sprinkler systems are always connected to the fire alarm system (in commercial buildings). There’s a flow switch on the system somewhere and when it detects water flowing it’ll trigger the system. Most fire alarm activation scenarios allow for the alarm to be silenced, but waterflow alarms cannot be silenced, you have to reset the system, and if the flow switch is still active, the system will sound again after you reset.
now i know why the laundry room has the green bulb yay
Also the liquid doesn’t expand the air bubble that is in the liquid expands and the temperature difference between the heads the air bubble is smaller and bigger
I was wondering how these work thank you
Great explanation. Sir, let me share this youtube channel for my friends in my office to share this knowledge. Thank you
So smoke doesn’t trigger them 😂 I learned something new
Tools saving lives.
Was at YMCA Toledo ohio. One way up high in a swimming pool room. One opened up with no fire. I was thinking about it five minutes before it happened.
*This is very informative and relaxing haha! The narrator has such a relaxing voice* 🔥
Most valuable information 👌
at 2:51 that isn't a pre activate system that is a recessed fire sprinkler pre activate sprays some sort of foam
For some reason, I have a massive fear of these. I will not go into a shower if there is a sprinkler in there. I refuse to goo a small room if there is a sprinkler inside. This has kinda helped
I know what you mean, I’m just scared it will go off even if there is no reason for it to. I have a similar fear to smoke alarms as well 😅
@@skatingrat3502What an irrational fear
Yeah. Get a fvcking grip ffs.
Ignorance of the general public is mind blowing.
As someone who designs/install fire sprinkler systems, this makes absolutely no sense to me?? 😂 Why the fear?
@@collectgemsosrs6298 I don't really know. It's just one of those fears that make no sense.
I love your video.
its a good generalinfo video. but many pictures and small general stuff is wrong.
Very informative video thanks allot.
Most educational. We have the red pipe sprinklers at our apartment.
I have noticed red is the most common.
what is the software that you use to make this 3D animation?
Very interesting!
Sir i want to buy how much 1 fire sprinkler
If only it was this simple
Watching this to know if I can still vape inside hotel room.
អរគុណ បង❤
Great video. I learned a lot even after being in fire protection for 2 years
Hey hows it going. I'm interested in this career . Any idea where to start?
If you didn´t know that being in fire protection for 2 years, you are bad in your job. I learned all of this in my first 3 months on my job.
@@d.j.105 start apprenticing at companies
love it... why are different colors of bulbs for different temps used?
different temperature sprinklers are needed in different parts of buildings and as an installer it would be a nightmare trying to figure out which one is which if they are all the same color. Kinda like a guaranteed way to make sure the right thing is where it needs to be. :)
I'm thinking the color of the liquid has chemicals in it that can withstand high temperatures that's what makes it the color.
Do you happen to know how far away does the sprinkler needs to be from a wall?
Sorry, I don't know the exact numbers but NFPA 13, 13R or 13D standards are used for sprinkler installation.
4 inches is the minimum for most applications.
You can learn NFPA-13 at Chapter 10 Page 10-80 have explain about ur question. First we need to know our fire hazard because its mean light or ordinary or extra hazard. All of these hazards have maximum distance from wall.
Most of the hazards allows 1.5m or 5ft, but as someone says here, it depends a lot of your hazard and a lot lot of things that must be considerated.
if the tube on the sprinkler breaks how do they replace it
You isolate the subsidiary stop valve leading to that sprinkler head/zone, or use the main isolation valve in the sprinkler installation (then drain remaining water if needed to do manually) and simply screw on a new sprinkler head, then de-isolate it. In Australia at least, AS1851-2012 requires spare sprinkler heads to be available for each installation at a site.
Whats the nameof the song in the bareground plz

I’m going to get a little more information from my friend
Yes I like the movies where all the sprinkler heads go off that's only in the movies
You are almost 100% right. However, There are some systems where all the sprinklers are open and that would happen, very uncommon though
@@cleatis79 depends I guess I've installed quite a few deluge systems, but yes not as common.
:47 is a deflector, the whole thing is the 'sprinkler'
Dry systems are most commonly filled with compressed air not nitrogen
@@cleatis79 that's in buildings with freezing temperatures. That's called a dry system. But regular systems are called wet systems. So only the effected sprinkler head will go off.
Sprinklers help you to keep safe because if it's fire the sprinkler will come out
Did anyone notice slide at 0:09 seconds? Common
Nice catch 😁 This is because the camera goes through window glass.
👍🤝😊
Hi sprinkler
Dry systems CAN be filled with pressurized nitrogen, but 100% of the Dry Systems I have designed use plan old air. Nitrogen can get very expensive.
Sir, liquid name in sprinkler
Mainly glycerin.

Seating at hospital
Looking at the ceiling
And wonder how sprinkler system works....🤣🤣🤣 Boring
How about after the bulb breaks the plug gets pushed out from the orifice and then water hits the deflector. Should of had a sprinkler person review first.
Big fear of these for no reason. Sprinkler in shower? Nope, near a fire sprinkler? Get me out of there. Alone with a sprinkler with me? *AAA* like the comment under me i have a fear of them and its stupid. I wish i didnt have it
Any sprinkler with a yellow bulb over higher is unsafe.
I DONT HAVE AN SPRINKLER OR FIRE EXTINGUISHER💀💀💀🔥🔥😭💀🔥😭
you sure spronklers are good at putting out a fire?
Not all , some have to be designed in specific ways like there orifices should be larger and water density should be more or else in case of a fire these water droplest can evaporate due to heat and due to which the fire can spread causing nearby sprinklers to activate resulting in loss of pressure on the sprinkler head directly over the seat of the fire.
The purpose of a sprinkler isn’t always to directly extinguish a fire. It’s to assist with compartmentalising a growing fire and preventing it from spreading to different compartments or exposures until the fire brigade arrive, hence the circular shape. It’s like a shielding dome around the fire.
