To all the people saying that it's a smoke detector. Well, no it's not. The system is under water pressure. When the fire heats up the glass bulb, it literally shatters and let the water out
@@RAXITH_playz then you will have a more complex solution that will be able to select where exactly to release water. Here, the simplicity of this one makes it all the more, a reliable solution
@@RAXITH_playz Because the chances of anything occurring at any time are present. Factors like cost and time spent could change the way construction and engineering are organized. Because the construction and maintenance of a building require many groups of people, adding all these clever ideas would increase complexity, thus increasing the cost of production and engineering. Still, one can say that the benefits are great than any actual monetary cost, yet in a natural environment, these standards are generally not applied. But maybe one day you can change those rigid standards and possibly help more people with your ideas.
In a real fire, the temperature at the ceiling would rapidly rise and set the sprinklers off. This tiny little flame is nothing in comparison to a real emergency situation.
Sprinklers act as the water output. You need fire detectors and smoke detectors and sprinklers on and off according to those sensors. If you wait until the fire reach the sprinklers, you may have nothing left..
Fire sprinkler systems are actually quite sophisticated, and are designed to be heat sensitive so that sprinklers only activate when the temperatures rise to fire-induced temps, usually somewhere between 155F to 165F, and only fire-related temperatures can trigger fire sprinklers. That’s why it’s takes a while with the small flame.
There's a difference between testing and activating. This is activating. Now you have to call a certified Fire Sprinkler Company to come out and replace the head you just set off because it is no longer good, as well as recharge the system. For those that are stating it took too long for the head to activate, fire sprinkler heads are designed to activate at specific temperatures. Whatever the temperature was for this head (155, 165 or 200 degrees), the fire had to reach it before it was activated. Testing a Fire Sprinkler System is not done this way. Contact your local certified fire sprinkler company to have it tested by a qualified technician and NEVER activate it this way.
In carparks it's usually 100+°C or the green ones. Well it's like that here on our firecode because carparks can get hot and nuisance activations are sometimes the reason why firefighters go to calls
Yeah. It's funny how the AHJ in our country also want an annual sprinkler bursting when in fact there are inspectors test valves which are designed to simulate the same.
Does the System detects smoke or fire/temperature?? if it's smoke , then if he have burned a piece of paper or Cloth then i think it could have Activated earlier..??
That’s actually not true. In most sprinkler systems this is how they work. Only in certain types IE deluge systems are all of the sprinkler heads open, and that is only used in high risk situations like gas or oil or chemical storage
Each sprinkler head has a glass bulb with liquid that expands a a certain temperature. When the fire reached that head and heats it like in the video the liquid expands and bursts the glass bulb with a opens the sprinkler head. The goal is to put out the fire before it spreads to other heads. In a real fire by the time the fire is big enough to ignite the head there will be enough smoke to set off a smoke detector and set off the fire alarm to evacuate the building. Smoke detectors are life safety, sprinkler heads are property protection untill the fire department can get there to finish.
Fire sprinkler work by heating an special ampule that has a liquid which expands when heated and explodes under the high pressure letting the water flow, thats why it took so long the liquid needed some time to heat up with that small flame if the flame was hotter or bigger it would have worked
Indian technology "Once the fire has been raging for atleast 5 minutes, the sprinkler will turn on just before the entire place is completely burnt to the ground.
@@kunalsolanki5216 Considering I used to be fire rescue.... yes. There's a wax filament that needs to burn/ melt away in order open the valve. It's extremely archaic technology. The new ones have extremely sensitive bimetal release valves and laser smoke detections. The wax release sprinklers are only used in very old buildings or 3rd world countries.

Matlb jabtak fire vo sprinkler ko touch nahi hoti ho zameen se 10ft upar hai, tabtak sprinkler chalu nahi hoga............ Matlab sprinkler start krne ke liye aag ko atleast 10 ft badi rehna padegi. Tabtak niche ka sb jal. Ke khaak ho jaega....... Shandaar technology h bhai!! Inko noble prize do plz!!!!!!

Sprinklers are "Fire suppressants" not fire extinguishers. They're not designed to put out the fire. Its a possibility depending on the size but most sprinklers wont be able to put out a fire in time it'll be too big by the time its triggered.
@@Iw1372 Lmao okay bud. Look up fire suppression system and see what the most common fire suppression system is. "What is the most important goal of fire suppression systems? Preservation of Life - The primary objective of your fire safety system is to protect the individuals inside the building." It's to give people more time to get out. It's possible a sprinkler could completely extinguish a small enough fire but that's not the goal. If I was actually wrong you'd be able to explain but you don't know what you're talking about so "You're wrong" is all you can say.
If the flame has to be that close to trigger the sprinklers, the room will have to be completely engulfed in flames to trigger it. Everything worth saving will already have been incinerated.
It did take a while. I assume they are in a different country though, so I’m not familiar with the standards there. Garages typically have higher temperature heads, it depends on building construction and occupancy type. (NFPA13)
As a career sprinkler fitter, I don't understand why they would set the head off. Most systems have an inspectors test set up on it so you don't have to bust a head.
Air is in system, water pressure drops it's wrong to assume the fire that created so intence heat near the bulb would get suppresed , area covered too is not enough
clearly people in the comments don’t know how a fire system works, he had a little flame, the bulb depending on what type sets off a certain temp. if there was a actual big fire happening, they would go off almost instantly. they don’t go off because of a little flame being put on it. it takes the required heat for them to set off
Yea nobody understands. I know a thing or two about these things and they are not going to go off to a flame the size of a birthday candle. It takes big fires. They are there in case fire extinguishers don’t do the trick or when nobody is there to put out the fire.
Sensors are super cheap i'd say it should sense it from further distance if the the fire gets the time to get that close to the sensor there won't be any point of sprinklers everything will be burnt or on fire already.
Bhai aisa system hona nahi hona same ha 😂😂😂utne upar aag pahuchegi woh pipe garam hoga then thukna suru karega usseh accha toh balti seh paani laa kar pheko
They aren’t sensors. Each sprinkler has a temperature rating. Standard temps include 155, 200 and 286 degrees F. Once glass bulb in the sprinkler heats up to its corresponding temperature rating, the glass bulb breaks and the water is released
People saying there's a delay have no clue what they're talking about. You can clearly see once the sprinkler head activates there's water on the ground instantly as the installation/sprinkler pipe is charged with water. The sprinkler glass bulb is heat activated from a small bubble inside the glass bulb expanding and breaking the bulb once the head reaches its operating temperture. There's different temperature rated heads for all different enviroments. The only way there would be a delay would be if this was a pre action system which are typically used in high water sensitive areas. Also use the waste and test drain to test the sprinkler system ffs 😂
Dry and reaction systems would cause a delay in activation. And since they are in a parking garage I'd say it's a dry system because preaction will require 2 devices before water will flow
I can understand your comment as layman side of view, the head sprinkler has some different working temperature,, the lowest once you can select the working pressure at 57 Celsius degree, the highest until 270 degree. From this video, no such of the explanation of the type, just testing it.
Bhai ye testing to aapki fail hai, jitni der tak aag sprinkler per lagani padi ki capsule burst ho jaaye itne me to already sab jal kar rakh ho jaayega 😂😂

Agreed. Not to mention this is in a car garage. Potentially a dry system which by NFPA standards can take up to 60 seconds to fill once the bulb breaks releasing the air from the pipe and allowing the water to pass the Check Valve.
It's not slow response. It's normal good response It's waiting to see if anywhere else if there is fire like if ur in mall and fire it will spread to different areas then it will activate this person just kept only one stick and he waited for some time so the sprinkler thought it started to spread
1.The fire have to reach its maximum height to break the obstaclection in the sprinkler ....... 2.It is taking too long time ... 3.I think the rate of flow of water is not enough to control big fire .... Iam just saying what I have noticed in the video ........
By the time that much flame reach to sprinkler everything would be lost. It should be quick response with good sense of temperature. Other wise it's waste.
@@lawrenceevans4920 It took way too long to trigger. (I'm now referring to german VdS CEA 4001 standards:) If this sprinkler head was really at 68°C activation temperature it's supposed to break at about 80 mili seconds.
@@doofnuss6 do you work on sprinkler systems? Just asking because you seem to know a lot about how a sprinkler works. It took not very long to activate. It was actually a good activation time.
Si las llamas están a la altura de los sensores aspersores, ya no queda absolutamente nada por salvar, se supone que debieran actuar por humo y temperatura, sólo así puede prevenir la expansión del fuego

Fire has to reach to the nozzle....or else it wont work... 😂😂😂.. Jab tak fire buld tak reach hoyega.. Tab tak to sab kuch jal 😂jayega....wats use of this...
No Sir, you are totally wrong. a lot of people smarter than you have developed fire sprinkler systems and have about a 96% success rate in saving the building. That's almost perfect The clowns conducting this test are far from the experts who developed these systems and they do work. Nearly every time. Educate yourself. Its obvious that not many in your country do. So you could be like the smartest one in your town.
There are several temperature rating sprinkler heads Judging by the length of time it took this sprinkler to go off the sprinkler head is above a high temperature. The concrete and steal building isn’t going anywhere lol so let’s relax
