Series DS-8 Dry Sprinklers


For Areas Exposed to Freezing Temperatures

DS-8 sprinklers are used in wet, dry, or seasonal safety systems where the sprinkler or piping is exposed to freezing temperatures – for example, in the wall of an unheated building. Due to the potential for ambient freezing temperatures to freeze 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.
