  • The " juice" inside the glass vial on the sprinkler head doesnt expand actually... the color of the liquid inside only designates the size of the tiny air bubble loaded in each vial... so..the bigger the bubble...the lower the temp it takes to break the vial and trigger the sprinkler. 🔥🚨

  • That’s not how sprinklers are made and the US, they just have smoke sensors, when they go off the metal gear shape spins and gets a wider angle of output, there’s no crystal

  • Another great video. I didn't see in the comments that in a real sprinkler installation there's no water in the system. The whole system is filled with air under a low pressure. When one of the capsules is triggered a sudden drop in (air-)pressure is detected. This will open a valve in some small pressurised watertanks to fill the pumps and to start filling the tubes with water. At the same time these big pumps (driven by electric motors) are started. After just a few seconds the sprinkler will flood the area. The advantage of the dry system is, is that you can detect leaking seals without dripping water into someones keyboard or so (there will be air lost without the sudden drop). This also makes maintenance a lot less messy. Valves permits to isolate floors to locate the section with the leakage. With an ultrasound microphone you can then find the leak in the concerned area. Hope you found this interesting. Tada from me and looking forward to the next slow-mo.
