Fire sprinkler systems don’t work the way movies show them. In real life, only the sprinkler closest to the fire activates, responding to heat and releasing water exactly where it’s needed. In this video, we break down how fire sprinkler systems actually work, from the small glass bulb inside each head to the hidden network of pipes, pumps, and water supply behind the walls. It’s a simple system, but one of the most effective forms of hidden infrastructure protecting buildings every day.
