A fire sprinkler is a safety device designed to automatically extinguish or control fires in buildings. It consists of a network of pipes filled with water and individual sprinkler heads that release water when a fire is detected. Each sprinkler head is equipped with a heat-sensitive element that activates when temperatures rise, allowing water to flow and suppress the flames. Fire sprinklers are commonly used in commercial and residential properties to enhance fire safety. They can significantly reduce the risk of fire damage and save lives by providing immediate response to a fire incident, often before firefighters arrive on the scene.
