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.
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
Sprinklers are intended for life safety, not just fire suppression. The sprinkler water can cool the environment so occupants have a better chance of escape/survival
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
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. :)
In dry climates where fires 🔥🔥🔥🔥 are becoming more prevalent, maybe 🤔 after the house or building is burnt 🔥 down they can be rebuilt with these in mind. Or perhaps insurance companies can give discounts to those who install these systems.
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.
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.
@@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.
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
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.
Based on both the misinformation in the video and the comments, there is a whole lot of clueless people out there. First, sprinkler “head” is not correct. That is an old Factory Mutual term. The NFPA does not use the term “head” in any of their sprinkler standards. They are just a “sprinkler” or “sprinklers”. Not all sprinklers use a glass bulb as the thermal response link. There are other. Furthermore, the temperature rating is indicated, but not determined, by the color of the liquid in the bulb. Temperature rating is principally determined by the size of the gas bubble in the bulb. For Dry pipe systems, the gas most commonly used in the piping is just compressed air, not pure nitrogen. (NFPA 13 describes five types of systems: Wet pipe, dry pipe, preaction, deluge, and dry pipe-preaction.) Limiting the number of sprinklers that open is principally not to limit water damage, but rather to prevent an excessive demand on the connected water supply. As a degreed fire protection engineer of nearly 50 years, I cringe every time scientists try to describe how fire protection works.
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.

Would a frozen bursted pipe cause it to go off?

at 2:51 that isn't a pre activate system that is a recessed fire sprinkler pre activate sprays some sort of foam
now i know why the laundry room has the green bulb yay
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.
Most valuable information 👌
Tools saving lives.
I was wondering how these work thank you
I love your video.
*This is very informative and relaxing haha! The narrator has such a relaxing voice* 🔥

its a good generalinfo video. but many pictures and small general stuff is wrong.
Great explanation. Sir, let me share this youtube channel for my friends in my office to share this knowledge. Thank you

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.
Most educational. We have the red pipe sprinklers at our apartment.
I have noticed red is the most common.
Very informative video thanks allot.
what is the software that you use to make this 3D animation?
អរគុណ បង❤
Watching this to know if I can still vape inside hotel room.
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.
If only it was this simple
Did anyone notice slide at 0:09 seconds? Common
Nice catch 😁 This is because the camera goes through window glass.
Very interesting!
So smoke doesn’t trigger them 😂 I learned something new

if the tube on the sprinkler breaks how do they replace it

Sir i want to buy how much 1 fire sprinkler
DEPENDS SIR
WHAT 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.
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

Sir, liquid name in sprinkler
Mainly glycerin.

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.
I’m going to get a little more information from my friend
Sprinklers help you to keep safe because if it's fire the sprinkler will come out
Hi sprinkler
2022
Seating at hospital
Looking at the ceiling
And wonder how sprinkler system works....🤣🤣🤣 Boring
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.
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.
👍🤝😊

you sure spronklers are good at putting out a fire?
