What is a fusible link sprinkler head?

A fusible link sprinkler head is a type of fire protection device that activates when exposed to high temperatures. It features a metal link that melts at a specific temperature, releasing a cover and allowing water to flow and extinguish or control a fire. This mechanism ensures that the sprinkler activates only when necessary, minimizing water damage to areas not affected by fire. Fusible link sprinkler heads are commonly used in commercial and industrial settings.
