The point that he missed was that dry systems are mainly installed to prevent sludge and rust in the stagnant pipes from blocking the heads. Her in the UK, wet systems are flushed through by the service engineer at least once a year.

I always meant to get round to researching the true answer.. Thank you .. now that is one I can now tick of my list.

When I was in college somebody used a lighter to burst one of these things in my dorm. It ended up dripping through 8 stories of the building, including a radio station and an urban outfitters located below, and if I recall correctly, doing $20,000's of damage. And that was just one sprinkler going of in the building. It took the building hours to deal with the problem, and we had to spend the night in the lobby of an apartment building across the street.

Reccaman from what i have been told, if the element in the fire sprinkler is clear it has something to do with the ambient temperature/sunlight. You can google this (simplex) there is no sprinkler that comes factory with no identifying color. I have also been told that if you put the “clear element “ in a cool place the color will come back

could you please elaborate on working of sprinkler having inert gases or foam

Awesome thanks for the knowledge 😊

Being a fire sprinkler fitter, good job on this one

Is there a video about smoke alarms by DNews? I already know how they work, but it would make a neat video for those who don't.

I wonder if the "classic" sprinkler heads with a gallium plug are still in use? Gallium, a metal related to aluminum, melts at about 85 degrees Fahrenheit, so a plug of gallium would melt and release the valve when the temperature at the ceiling reaches that value.

thank you, outstanding, concise and comprehensive, go ahead and do more for the whole F.F. Systems

Is it true that no building properly equipped with sprinklers had a fire run out of control?

Everything he said is 100% correct! one other thing is that when the sprinkler's activate, it trip a device called a water flow switch. When that switch is activated is activated the fire alarm system.

how a sprinkler really works is theres a heat sensitive liquid inside a tiny glass tube and builds up pressure and explodes breaks a vacuum tube witch lets water flow water though or it breaks and lets water inside the tube flow down and the tip makes it a spinkler

I figured this out when I was just a kid, granted I thought it was different hardnesses of wax that triggered at the right temperature. But that was only because I was too short to see them in detail.

Could you still set the system off by, say, bludgeoning or shooting one of the sprinklers itself?

Red isn't the lowest bursting sprinkler head, it's orange; it bursts at 135 degrees. Red is simply the most common used for residential and commercial applications. Also black sprinkler heads aren't rated for 650 degrees, they're rated for 500. Most heads that you see in warehouses are usually green and occasionally blue.

Deluge systems like you see in movies are very rare. I’ve only ever seen one in years working in fire safety.

ive installed well over 10.

to add on. most newer sprinkler system's have a electric pump to build pressure. when the bead breaks the pressure will fall fast and a big electric or diesel pump starts up to produce low pressure but high volume off water. u can see this when it beaks u get a splash then a drip and then the big spray. as a bonus if u get a very small leak or a drip the small pump can sens that and warn the maintains team and not trip the big pump and the alarm.

@barryrose8360

6 жыл бұрын

SoY_FooD no, that is incorrect. You only get a fire pump if you do not have the pressure to support a sprinkler system. Nobody installs a $75,000 pump just because. Secondly, once the bulb or fusible link is broken you will immediately get the water pressure in the system. No drip and then big spray. If you are talking about a dry system, you will get whatever residual water may be in that system (probably just a mist) from testing and then you will get whatever pressure the dry valve is holding back. But, yes you are correct about the jockey pump. This maintains the system pressure generally to within 10psi of the main fire pump. However, there is no warning that I’m aware of to the maintenance team unless they are seeing the jockey pump running excessively. The jock pump is supposed to run when it detects a loss of pressure.

It is possible to physically break the bead causing the system to activate?

I always though that the red was wax and that it melted to let the water out.

also in a wet system, the water inside will be absolutely filthy to the point where it is black due to sitting in piping for what is most likely years on end.

thanks

The main purpose of them is so you have a much higher chance of getting out alive. Most cases they will put out or seriously hinder a fire, but their purpose is life safely, not saving the building. The flood damage is typically higher than the fire damage when these systems activate. Hence, almost always, the fire system does more building damage than the fire.

Dry systems are not empty, they have pressurized air inside the pipes. When a sprinkler head goes off, the air-pressure inside the pipes drop dramatically telling the system to open the valve for water.

People install these systems due to the lower cost. It is a very false economy, particularly when they trigger accidentally. Some insurance companies exclude water damage in areas remote from any fire area.

How about air ducts in buildings being used as an escape route!

To add, the water that comes out of wet systems is also laden with oil that was used to cut and tread the original piping. This "water" is black and smells like oil. It may save your building, but everything that is under that particular head will be all but ruined.

How it is stop

It seems like they also wouldn't want all of the sprinklers to go off at the same time because they wouldn't want an entire building to get water damage if there was just a localized fire.

got up and walked around my building just staring at all the different sprinklers

...over 300°C.. at least Trace told it correctly :)

When I get a house, I'm gonna have it built like a commercial building. A building built of 2x4s is asking for trouble and fire. Your average house is like a pile of twigs.

Dry systems do have pressurized air in them

I am pretty proud of myself. I figured this out on my own working in a sbarros pizza in the mid 2000's. We had a low ceiling where you could touch one of the heads and I realized that they are independent of each other. I did however think they used a wax rod and not a glass tube but I was close.

I really hate the person who decided it was a good idea to put the subtitles in a yellow frame. When I see a shiny colour (like the yellow in the frame) contrasted with another bright colour (like white) it gets borrowed, I can barely see anything, and it tires my eyes so it hurts within a few minutes.
