The Viking Corporation, a provider of fire protection and life safety systems, enhances the cULus Listing for its 5.6 (80) K-factor quick response COIN® sprinkler.
The new Listing allows the VK950 upright sprinkler to protect combustible concealed spaces without the use of draft curtains in most applications, making it an ideal replacement for competitive sprinklers that have more stringent and expensive draft curtain requirements.
Glass Bulb Sprinkler
The new VK950 UL Listing applies when sprinkler spacing is up to 16' X 16' (4,9 m X 4,9 m) for truss construction with top chord member on face (not on edge) for wet or dry systems. The Listing is also applicable when sprinkler spacing is up to 14' X 14' (4,3 m X 4,3 m) for trusses with top chord member on edge or solid wood joists for wet systems. The updated VK950 technical datasheet contains complete design and installation details.
The COIN® VK950 5.6 K-factor Quick Response Upright is a glass bulb sprinkler with a thread size of ½” NPT (15 mm BSPT) and an intermediate temperature rating of 200°F (93°C). Available finishes include brass and an ENT coating for installation in corrosive environments.
