UL Listed Standard Response Concealed Sprinkler

Overview

The concealed sprinkler head uses a secondary temperature sensing action. In the event of a fire, the ambient temperature first melts the fusible alloy weld between the outer cover and the base, causing the cover to detach and the deflector plate to move downwards. Subsequently, as the temperature continues to rise, the internal glass bulb ruptures due to heat, and the sprinkler head begins to spray water.
