Fire sprinkler activation test

Video description:

A hand brings a lighter flame close to a fire sprinkler head mounted on what appears to be a ceiling or overhead fixture. The heat from the lighter flame triggers the sprinkler's thermal activation mechanism, causing the sprinkler head to activate and begin spraying water. The sequence shows the moment when the sprinkler system responds to the heat source by releasing water in a typical spray pattern, demonstrating how fire suppression systems are designed to activate when exposed to sufficient heat.
