Friday, March 2, 2012


Hastings, Michigan, USA - With the release of its model VK486 horizontal sidewall sprinkler, Viking Corporation, a global leader in fire protection and life safety systems, has set a new standard in performance for residential fire protection. The VK486, which is the latest addition to Viking’s leading Freedom® residential line, is cULus Listed with a flow rate of 13 gpm (49.5 L/min) for a 16 x 16 ft (4.9 x 4.9 m) room size. This is the lowest UL Listed flow rate possible for NFPA 13D or 13R residential sprinkler systems requiring a 0.05 gpm/ft 2 (2.04 mm/min) minimum design density.

Built from Viking’s patented flow shaper platform, the VK486 sprinkler also offers larger coverage areas including 20 x 20 ft (6.1 x 6.1 m) and 16 x 22 ft (4.9 x 6. 7 m). Furthermore, in each of its UL Listed areas of coverage, it provides the lowest flow rates available in the industry. The result is a ground-breaking new sprinkler that offers contractors a distinct competitive advantage in designing the most efficient and cost-effective residential fire sprinkler systems.

The new Freedom® model VK486 sprinkler is available in 155°F (68°C) and 175°F (79°C) temperature ratings. It can also be ordered in several standard colors and a nearly unlimited range of custom finishes to match virtually any home decor. The new sprinkler is approved for installation up to 12 in (305 mm) below the ceiling for greater flexibility around light fixtures, sconces, large crown moldings, and other potential obstructions. It is also available with Viking’s exclusive Model G slope ceiling escutcheon, which allows for easy installation in slope ceiling arrangements.
