Hastings, Michigan, USA - The Viking Corporation, a global leader in fire protection and life safety systems, announces that it has successfully completed all UL testing for its new Freedom® residential flat plate concealed pendent sprinkler (Model VK494). The new 4.9 K-factor sprinkler, which will be available this fall,representsa significant advancement in residential fire protection.
The new VK494 is UL Listed at the minimum flow rates for 16 x 16’, 18 x 18’, and 20 x 20’coverage areas in all three of its available temperature ratings; 155°F, 175°F, and 200°F. It is the first residential concealed sprinkler with the same listed flow rates for both ordinary and intermediate temperature- ratings. As a result, residential sprinkler installers can now standardize on an intermediate temperature-rated sprinkler, without having to sacrificeeither performance or aesthetics.
While ordinary temperature-rated sprinklers, with an operating range between 135°F and 170°F, can only be used when ambient temperatures are below 101°F, intermediate temperature-rated sprinklers (175-225°F) can be installed in environments up to 150°F. Standardizing on intermediate temperature sprinklers offers several benefits including greater installation flexibility around potential heat sources such as fireplaces, heat diffusers, skylights, and ovens, as well as reduced inventory complexity and less confusion at the job site.
The new Model VK494 sprinkler is available with three cover plate styles (standard diameter, large diameter, and square), each offered in nine standard finishes and a nearly unlimited array of custom colors. The cover plates, as well as installation wrenches, are the same as used on Viking’s current line of residential concealed pendent sprinklers.
