Water is normally discharged whenever a sprinkler is broken or set off by heat, except for a dry system which is charged with air, this is to avoid frost damage, air will discharge first quickly followed by water - However I sense you are referring to a Pre-Action system, these have special control valves that only release water into pipes after a set of detectors sense a fire, normally before a sprinkler would activate - and therefor if pipe or sprinkler was damaged, these valves would still hold back the water as no fire was detected. This is explained just after the 7 minute mark in the video.
Thanks, the video itself actually dates back to the mid 1990’s, although standards have updated, the basics remain the same, I am glad you found it helpful.
Invented 120 years ago, still cost like $6,000 dollars to get installed in a home.💰 Not sure how much it cost else where but in America it's expensive.
I think there are some sprinkers that can be activated manuall but I I thinks its only common in an industrial application if I live in a condo which I do the buildings around are mall houses theaters and hosopitals and grocery stores I think a system that would allow for manual activatiion is limited to special insdustral building maybe an aircraft hanger or something int he above metioned buildings they have an automatic sprinkler system if any most sprinkler systems do not have a method of manual activation but most building like the above mentioned may possibly be required in addtion to having automaitc sprinklers like the things metnioned above could possibly be required to have automatic fire extinguishers like over a restaurant fat fryer such a system example here these type of extingusihing systems might allow for manual activation : th-cam.com/video/Ktnc2Xsub0s/w-d-xo.htmlsi=bOzksecpmp8Ki_QF
One of my favorite passions while working Security was learning about fire systems. One mall I worked at had actual Fire Life Safety guys that were full time, they were a huge help. As the years go by sometimes branch lines get installed (retail suites are always changing size and location) so System 10 may now service a different suite or area than in years prior as an example. I loved draining and filling systems. I got good at panels as well. I'm usually the only non "expert" that can disable devices, figure out if a waterflow sensor is acting up, heck even filling a system correctly (if you leave too much air in a wet system you can trigger false alarms etc). That being said, I only have experience with wet systems so I still have a ton more to learn. I think I might go into the Fire Life Safety field!
You should do it! I was a security director and learned all about the trade from the engineers in the building and the contractors that came in to work. After proving my competency and good work ethic they picked me up and its been amazing. Life changing
i have hit one with a axe and the head did not go off. they work. had to put some heat on it to get it to trip.... Fire Department we had a small fire in a building to small to trip the sprinkle but big enough it was a problem. stupids left paint thinner in the stair well next to the ashtray.
Mmm glass tubes, with the liquid inside, that bursts when heated....and only still the sprinklers will activate when heat is present...not when the tube gets damaged, now I know how they work! Very interesting.
Are Europeans stingy with oxygen masks for firefighters or...? Cause in America in those scenes of firefighter in action each would be wearing oxygen. Also, in Europe, is it common for sprinklers to be in homes?
I don't believe they are stingy, no-one would deny protective equipment where needed, I noted they do have oxygen in some scenes (going into buildings) and perhaps the external scenes either do not need or the angle may make the fire look closer. I would not say it is common, each country makes it own legislation, they are more prevalent in Nordic countries such as Sweden, Norway, Denmark and Finland. The UK is becoming more aware of the benefits after Grenfell.
my true question for you is if you are calling scba oxygen how much do you really now about firefighting ??? scba tanks contain special compressed air I refilled a few of those type cylinders when I was employed at the fire department I was never shown how to fill a cylinder with oxygen !!! which could possibly be more dangerous and you would possibly need more specialized equipment to do so ???
@@tbah9402 If you live in an appartement the fire can start downstairs. By the time you are aware of it, it might be too late. Most people die from the smoke caused by the fire and not the fire itself.
The Generalissimo so many models and so many variations on deflector styles, but biggest mistake is assuming all sidewalls are horizontal sidewall type.
@@stuartlloyd2861 Yeah, they're pendant ones and they hang down, and the deflector points TOWARDS the wall, which I thought was funky, so I came here. Lol.

you know this video was made by Wormald
Yes, I once worked for them
Perfect information. Thank you.
Sir,Why sprinkler head have red color and greed color and yellow color?
Indicates temperature rating of sprinkler
Thank you @@stuartlloyd2861
Thanks a lot. I was stuck in understanding the working of the pre-action sprinkler system. And here I'm clear and quite satisfied.
Such as everything,😊
Fire Brigade Ohh the english
Why doesnt any water come out if the glass valve of the sprinkler is destroyed by physical impact and not by heat?

@@stuartlloyd2861 Thank you!
now this, this is the type of video i like to watch at 2 am
It’s actually 2am rn lol😂😊
I'd love to know if the attack line blew off the side of the engine after that stunt at 4:45

Hi, friend, I'm a Chinese manufacturer. Can we get to know each other?
Hey, thanks for making this video. It's very informative.
Can this system be activated manually?!

Sir i want to buy how much 1 sprinkler water?
Please language Hindi translation

GREAT....
I saw that and I loved it!
Sir please explain about hydraulic calculation of Sprinkler and Standpipe system
Excellent video!!!
How to reset the system? Pls tell to meeeeeee
contact manufacturer for data sheet, each type or make of valve set may be different - ideally use a specialist contractor.
great content for everyone thanks..

If its flat send it back, if its cone leave it alone.
AWESOME
Superb sir.
I install these systems for a living. You’re welcome 😉
They don’t always active to fire dept
i have hit one with a axe and the head did not go off. they work. had to put some heat on it to get it to trip.... Fire Department we had a small fire in a building to small to trip the sprinkle but big enough it was a problem. stupids left paint thinner in the stair well next to the ashtray.
I install these systems very helpful and a life saving device
Very informative!
Thanks useful info for my studies
I love my job, 3 years ago getting into this industry installing fire systems and shit. Pays great😂
Is it your own business or you work for a company ? Because I’m thinking of starting a firefighting system business here in MENA region.
Mmm glass tubes, with the liquid inside, that bursts when heated....and only still the sprinklers will activate when heat is present...not when the tube gets damaged, now I know how they work! Very interesting.
this is wonderful, thank you we provide fire fighting system installation you can also visit th-cam.com/video/pz-1K2RX14w/w-d-xo.html
I had no idea that there were different types of sprinklers.

It's not oxygen, it's compressed air, 4500 psi.

A video from 2002 that brings back memories from that decade in so many ways XD
But this video is from 2014
My work I'm proud of your explanation
Proud to be working in Fire Sprinkler Systems
what a fantastic video
I will want to have sprinklers installed when I own my own house. Having them in my current apartment gives me peace of mind.
dickcheney6 try to get the pop out ones, they blend in with the ceiling and they’re way less likely to go off from something stupid like getting hit.
Just get a fire extinguisher
@@tbah9402 that’s not the same idiot
@@tbah9402 If you live in an appartement the fire can start downstairs. By the time you are aware of it, it might be too late. Most people die from the smoke caused by the fire and not the fire itself.
? That's ridiculous.
I'm trying to figure out if the sidewall deflectors are the rightway round in my local library. Hmmm. Edit, they're not. Hmmmm.
The Generalissimo so many models and so many variations on deflector styles, but biggest mistake is assuming all sidewalls are horizontal sidewall type.
@@stuartlloyd2861 Yeah, they're pendant ones and they hang down, and the deflector points TOWARDS the wall, which I thought was funky, so I came here. Lol.
