The Viking Corporation, a global pioneer in fire protection and life safety systems, announced the availability of new specific application window sprinklers.
Designed to provide interior protection of windows or glazing, the sprinklers are used with fixed glazed assemblies to provide an alternative to a fire-resistance-rated wall assembly and feature a unique spray pattern that coats the surface of the glass with water, reducing the risk of cracking or shattering glass in the event of a fire.
Sprinkler dimensions
Viking’s new window sprinklers are available in both pendant vertical sidewall (VK960) and horizontal sidewall (VK962) models. The VK960 is Listed for up to 12’ (3,7 m) spacing between sprinklers, along with 7’ (2,1 m) maximum distance from vertical mullions, providing significant installation advantages. The VK960 is also listed at 15 gpm at all spacings up to 12’ (3,7 m). Additionally, both sprinklers have a maximum pressure rating of 175 psi in all approved applications.
The cULus Listed sprinklers are available in brass, chrome, white polyester, black polyester, or corrosion-resistant ENT plating. With a thread size of 1/2” NPT or 15 mm BSPT, the 5.6 (81) K-factor sprinkler can be ordered with temperature ratings of 155° F (68° C) or 200° F (93° C).
