New Quick Response, Extended Coverage, Concealed Sprinkler for Ordinary Hazard Occupancies

Tuesday, December 6, 2011

Hastings, MI, USA – Viking Corporation, a global leader in fire protection and life safety systems, has introduced the industry’s first quick response, extended coverage, flat plate concealed fire sprinkler for Ordinary Hazard (OH) occupancies. The new VK538 Mirage® sprinkler, which is cULus Listed for OH-1 and OH-2 occupancies, provides for the first time the enhanced aesthetics of a flat cover plate with the design advantages of a QREC sprinkler in these applications.

With a K Factor of 11.2 (161), the VK538 is well suited for systems requiring higher water densities, as well as situations where the available water pressure is limited. Potential applications include casinos, hotel atriums, retail environments, libraries, automotive showrooms, and shopping malls. This new sprinkler further extends Viking’s leading line of Mirage® commercial concealed sprinklers, which includes standard and extended coverage versions in multiple K factors, as well as specialized concealed sprinklers for high pressure requirements, MRI rooms (non-ferrous), and clean room environments.

The new VK538 Mirage® is Listed for coverage areas as large as 20 x 20 ft. (6.1 x 6.1 m) and has required flows and pressures that are less than or equal to most non-concealed sprinklers for OH occupancies. The new sprinkler has a ¾ inch (20 mm) NPT thread size and is available in 165°F (74°C) and 205°F (96°C) temperature ratings. Like all concealed sprinklers from Viking, flat cover plates are available in several standard finishes and a nearly unlimited number of custom colors.
