Description

Protect Large Areas Exposed to Freezing Temperatures

Tyco® DS-3 sprinklers are designed to protect areas that may be exposed to freezing temperatures, such as a loading dock. They are intended for extended coverage use in ordinary hazard occupancies. They also provide a much larger protection area than a standard coverage sprinkler: 320 square feet compared to 100 square feet. 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.
