VK900 - Microfast COIN QR Upright Sprinkler (Specific Application)

VK-12493AD

Viking QR COIN® Sprinklers are quick response specific application sprinklers for combustible interstitial (concealed) spaces (i.e., between floors, as well as low pitch attics that meet the criteria. These upright sprinklers are designed for use in specific light hazard combustible, as well as non-combustible, concealed spaces requiring sprinkler protection. The orifice design of the Viking QR COIN® Sprinkler, with a nominal K-Factor of 4.2 (57 metric*), allows efficient use of available water supplies for hydraulically designed fire protection systems. The glass bulb operating element and special deflector combine speed of operation and area of coverage to meet the crucial fire protection requirement for shallow space combustible concealed spaces.

    Product Information

    In some cases COIN® Sprinklers can allow the use of CPVC piping within the concealed spaces of applications requiring sprinkler protection in open truss construction of both wood and steel trusses and solid wood or composite wood joist with upper deck filled with non-combustible insulation. COIN® Sprinklers can also be installed with steel pipe in protected areas constructed of solid wood joists, and solid wood or composite wood joist with upper deck filled with non-combustible insulation, and in open truss construction of both wood and steel trusses. When using steel pipe, COIN® Sprinklers can be applied as a dry system using air or gas as a supervisory medium.
