Gav and Dan like learning and like fast things. In this episode, they learn about a fast thing.
A fire sprinkler that you can probably see above your head if you are watching this from your office when you should be working. Shame on you! Nah, just kidding. Watch more Slow Mo Guys at work!

So the way that these are normally deployed , the pipes are dry and pressurized with air at around 45 psi (3 bar). This air pressure is holding a valve closed that is holding back water at about 120psi (8 or 9 bar). The ampule breaks, releases the air out. At around 20psi, the flapper valve flies open, and the system fills with water at street pressure. They spray a lot further when they go off.

Hello! Engineer for a company that makes sprinkley bois here! I loved the graphic that popped up at 0:52 about the colors and temperatures. The "glassy, juicy ampules" (lol Dan) are called bulbs, and like the graphic shows, the color indicates the burst temperature. Several factors determine what temp bulbs you want to install, the main one being height. For example, the sprinklers at the top of a warehouse need to burst at a lower temp because of how far away the fire is, compared with a standard residential or office ceiling height. Sprinklers can also activate via "links", which are basically little plate springs that are held at tension by solder paste. The fire melts the solder, the spring explodes outward, water comes out. The explosive quality of the bulb or link is important, because you have to get everything out of the way of the water flow. Some sprinklers, known as nozzles, don't have anything holding the water back! More on that in a minute! One last thing: if you're in a building with a flat ceiling and don't see any sprinklers, look for round discs instead. These are known as coverplates, and they provide an aesthetically pleasing way to cover a sprinkler from view! They can be color-matched to any ceiling, and like links, contain a solder paste that makes them pop off and expose the sprinkler at a much lower temperature than would actually trigger the sprinklers. Couple of myths: first one was one I used to think before working here is that the round bit on the sprinkler spins around as it goes off. Sadly not true for any sprinkler! That bit is called the deflector, and it's specifically designed to spread water in a certain pattern. Deflectors vary based on many factors, but primarily where the sprinkler is installed and the orientation in which it's installed. Many hotels use sidewall sprinklers with very different deflectors than the one in this video. Another big one: sprinklers always have water immediately behind them in their pipes, like Gav and Dan's in this video. Also not true! SOME systems are like that, and those are basic wet deluge systems. The problem with them is that it's relatively easy to have an accidental activation, which is the SECOND worst thing a sprinkler can do, because water from sprinklers can cause lots of damage, but not nearly as much as a fire. The worst thing is obviously if there IS a fire and the sprinkler doesn't activate. All sprinkler companies go through GREAT measures to make sure neither of these things ever happen! Back to water in the pipes: systems that do NOT constantly have water behind the sprinklers are known as dry systems, and they rely on a trigger mechanism to open the VALVE on the water main that holds back water to the system. The trigger is typically one of three things: an electronic signal from a fire/smoke detector, a wet pilot line, or a dry pilot line. Pilot lines are located with the sprinklers in the protection area, and are pressurized with either water or air (wet and dry). When the fire trips the pilot line, the pressure on the line goes away, which trips the valve to open and converts the dry system into a wet system, but only nozzle sprinklers go off at this point. Most wait until the bulb or link sprinklers trip. Obviously the pilot lines trigger at a lower temp than the sprinklers; that way the sprinklers always have water behind them when they trip. Some valves have multiple of these fail-safes, to further ensure against accidental activation! Any questions? I promise I can either answer you myself, or get a nice, smart coworker to help me out! Hope everyone is having a great day! 😊

The bottom of the sprinkler is called the deflector and the bulb pops and the whole brass seat falls out. And no they all don’t go off like they do in the movies just where the fire is that sets the sprinkler head off. I’ve been installing them since 07.

Fun fact: this isn't the only design for sprinklers! There are some that aren't one time use, but this style is by far the most common. The only "flaw" is that you can, y'know, break the ampule with physical force, but that takes more than a slight bump. Usually something more like someone doing cartwheels and kicking it or something silly like that.
