Series DS-2 Dry Sprinklers

Due to the potential for ambient freezing temperatures to freeze the water within the system piping, the sprinkler is comprised of a long dry barrel that separates the sealed water inlet from the activation element and frame/deflector assembly. Water is prevented from entering the dry sprinkler assembly until the temperature within the protected space is high enough to break the activation element thereby releasing the seal. Once the seal is released, the sprinkler is activated and water automatically releases.
