    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.

    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.

    • @dang48

      Which is why the system needs to be flushed every two years. It can foul a sprinkler head and interfere with its operation.

      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.

  • @Dredpath1
    @Dredpath1 8 ปีที่แล้ว +1

    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.

    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.

    @dnews The bulbs pictured in the video are called "frangible bulbs". Fusible links that Trace said, are small pieces of metal that have a low melting point, thus they melt and release the suppression agent. Great video though!

      @barryrose8360 6 ปีที่แล้ว

      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

  • @TheDerperado
    @TheDerperado 5 ปีที่แล้ว +1

    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.

    • @dang48
      @dang48 หลายเดือนก่อน

      True. The air pressure is what's keeping the valve closed and the water pressure behind the valve is what's trying to open the valve. When the air pressure drops, the water pressure becomes stronger and opens the valve through simple force.

    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.

    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

    @timm.6391 7 ปีที่แล้ว

    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.

    • @currbag

  • @ss4u2nv
    @ss4u2nv 8 ปีที่แล้ว

    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.

    • @Aaronproductions
      @Aaronproductions 7 ปีที่แล้ว +1

      ss4u2nv you can flush the system via a flow valve at the end of the run

  • @SoYFooD2
    @SoYFooD2 8 ปีที่แล้ว

    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
      @barryrose8360 6 ปีที่แล้ว +1

      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.

    Should of included how smoke alarms work, how does it know there is lots of CO2 or whatever in the air?

    • @dang48
      @dang48 หลายเดือนก่อน

      Smoke alarms work by 'seeing' the particles in the smoke when it enters their sensing chamber. The particles will either interrupt or scatter a light beam (photoelectric), or in the ionization type devices, cause a disruption in the ion field. The disruptions are sensed as changes in electrical current to activate the device.
      CO2 which is carbon dioxide is naturally occurring from us breathing etc and is a gas. CO which is carbon monoxide, is created when carbon based fuels like wood, gas, propane etc are burned without enough oxygen. That too is a gas and a different sensing system is required to pick it up.

    • @dang48

      That as well as:
      1) reduced pressure at the sprinkler head that is closest to the fire assuming it's the most remote from the water source
      2) additional hazards for evacuation like slippery floors/stairs, energized puddles where the water may come into contact with the electrical system and poor visibility.

      Pre-action system has no water in the pipes (dry pipe), and the air is not compressed. The system is initiated when a device like a smoke detector is activated. That sends a signal to the panel which then causes a solenoid valve to open and allow water into the pipes. That water sits and if there is a fire, the sprinkler head closest to it will open causing the water to be discharged. After the fire is out and the all clear is given, the supply valve is closed, the system is reset and the solenoid valve is allowed to close. The system is drained and the sprinkler heads that were opened are replaced before putting the system back into service.
      If there is no fire and the all clear is given, the panel is reset. The solenoid valve is closed and the system is drained before the system is put back into operation.

    Yep, seen it. Some hotels/motels have had to install signs to tell the stupid not to to use the sprinklers that way.

      Of course it does, any sort of heat at the right temperature will trigger the sprinklers.

      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.

    • @dang48

      @@WooferCooker Same with the dry pipe system. All closed sprinkler heads that are used in dry pipe, wet pipe and pre action systems are one time use and need to be replaced after they're activated. That bulb (fusible link in the older style heads), is called a thermal element and is designed to break when exposed to heat exceeding its temperature rating.
      The sprinkler heads in a deluge system though are open heads (no thermal element or bulb), and don't need to be replaced.

    • @dang48

      Exactly! That's with all closed type sprinkler heads. A deluge system uses open heads and those don't need to be replaced.

    • @dang48
      @dang48 หลายเดือนก่อน

      The glass is clear. It's the fluid inside that's colour coded to identify the temperature rating of the sprinkler head. That expands and breaks the glass bead to allow a small piece blocking the orifice to fall away to allow the water to flow out.

    • @dang48
      @dang48 หลายเดือนก่อน

      There are different types of systems in data centers. Inert gas, halon, clean agents and water mist systems. The halon is banned because it destroys the ozone layer. Water mist systems can be used as they produce very fine water droplets that will cool down the air and not cause issues with the electrical equipment.

    Why would you want to have it break at higher temperatures, wouldn't you want it to go off at the same temperature, you know, to prevent the fire?

    • @majorlazer914
      @majorlazer914 8 ปีที่แล้ว +1

      some warehouses where I live don't have air conditioner units and the temperature can get up to 120 F so I'm sure the ceiling gets even hotter so you'd want a sprinkler for a higher temperature

    • @silverlik
      @silverlik 8 ปีที่แล้ว

      Also some factories have machines which produce lots of heat, so thats also a reason. Or else the sprinklers will go off every time you use that machine.

    • @cluckedfuster2709
      @cluckedfuster2709 8 ปีที่แล้ว +1

      sometimes you want a sprinkler head to go off at a higher temperature so you do not have too many go off at the same time. if you have to many go off at the same time there will not be enough water pressure to get the required water density out of the sprinkler heads and on the floor to effectively control the fire. ( I do this for a living)

    • @dang48
      @dang48 หลายเดือนก่อน

      There are many factors involved. The occupancy hazard which is determined by the amount and type of fuels is one example. Different fuels have different temperatures when burning.
      As for preventing the fire, the water coming out would cause water damage. Fire prevention is done through other methods like safety procedures, maintenance etc. The sprinklers are there in case the prevention doesn't work and it hits the fan.

      no

    • @dang48
      @dang48 หลายเดือนก่อน

      That would happen only with a deluge system where the heads are all open. With a deluge system, the pipes are dry and when a fire detector like a heat or smoke detector activates, a solenoid valve opens to allow water into the system. Residential buildings would use a combination of wet or dry pipe systems and not a deluge system. A deluge system would be used in high hazard occupancies like a saw mill where there is a lot of combustible dust laying around.
      The dry pipe systems use closed sprinkler heads like the wet pipe system and have compressed air to hold the valve closed. Those would be used in colder locations like the parking garage which may not be heated properly in colder climates to prevent the system from freezing up. The heated areas in the building would use a wet pipe system. Both these systems don't have every sprinkler head going off at the same time. Only the ones that were closest to the fire would be activated.
      The only way all the sprinklers in your building would go off at the same time is if someone was running around breaking them or using a heat source to pop them.
