Viking Launches New Flat Plate Concealed Sidewall Sprinkler for Ordinary Hazard Occupancies

Thursday, July 26, 2012


Hastings, Michigan, USA - Viking Corporation, a global leader in fire protection and life safety systems, is pleased to introduce a new “flat plate concealed” horizontal sidewall sprinkler for light and ordinary hazard occupancies (Group 1 and 2). The new model VK481, which is Viking’s fifth concealed sidewall sprinkler, uses the same innovative design platform as the VK480 concealed sidewall for residential applications and VK680 extended coverage concealed sidewall sprinkler for commercial properties.

The 5.6 (81) K factor VK481 has a ½ in (15 mm) NPT thread size and is available in 165°F (74°C) and 220°F (104°C) temperature ratings. The cULus Listed, quick response sprinkler can be installed with the deflector between 4 and 12 in (102-305 mm) below the ceiling to better accommodate potential installation obstructions, such as light fixtures and crown moldings. With a total length of only 2 in (51 mm), the VK481 sprinkler’s compact design also allows for easier installation in tight wall spaces.

The sprinkler’s flat concealed cover plate provides an enhanced aesthetic solution for any area with an ordinary hazard classification. This may include applications such as hospitals, casinos, residence halls, automotive showrooms, libraries, mercantile, and exhibition areas. The VK481 cover plate, which is the same cover plate used for the VK480 and VK680 sprinklers, is offered in a standard white finish and is available in temperature ratings of 135°F (57°C) and 165°F (74°C). Additionally, through Viking’s UL Listed custom paint program, Viking can apply virtually any brand and type of paint to the cover plate for a clean, seamless installed appearance.
