Composed of a sprinkler frame, sealant, and glass bulb, the residential fire sprinkler is installed in the protected area via duct work, functioning as both a fire detector and an auto sprayer. When a fire breaks out in the protected area, the ambient temperature rises. The liquid inside the glass bulb expands upon heating and bursts when the operating temperature of the glass bulb is reached. Then the sealant drops, and the sprinkler sprays water into the protected area in a preset pattern to extinguish the fire.
