Product Description

Viking VK300 Quick Response Brass Upright Fire Sprinkler delivers powerful, affordable fire suppression in ordinary hazard commercial occupancies such as universities, auditoriums, churches, and parking garages. Using a heat-activated 3mm glass bulb, this automatic fire sprinkler opens when ambient temperatures reach 155F (68C), supporting rescue and evacuation efforts by lowering ambient temperatures.

The Viking Model VK300 has a 5.6 K-Factor and installs with 1/2" (12.7 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Quick Response Fire Sprinkler features a brass finish, brass frame, brass screw, brass or copper deflector, and a spring sealing assembly made with nickel alloy and PTFE tape.

With a discharge temperature of 155F (68C), these sprinklers activate early enough to provide robust protection to people and property while reducing the risk of accidental discharge. 155F (68C) Quick Response Fire Sprinklers are preferred for use in cafeterias, auditoriums, convention centers and other gathering spaces where human safety is the first priority. The Viking Model VK300 is a multi-purpose head suitable for use in covered horse stables, canneries, and many industrial applications.

With a maximum working pressure of 175 PSI (12.1 BAR), this upright sprinkler limits debris and ice buildup by installing vertically and may be installed and used in accordance with NFPA 13 and local fire code. Each Model VK300 sprinkler is made by Viking, a global leader in fire protection manufacturing for nearly 100 years.

This product is UL & FM approved for use in fire protection systems when accepted by the authority having jurisdiction. In accordance with NFPA 13, a higher temperature rating may be required when installing a quick response fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops.
