Residential | Freedom® VK494 Flat Plate Concealed Pendent Sprinkler

The new Freedom® Model VK494 is Viking's next generation residential concealed pendent sprinkler, featuring "ultra-fast" glass bulb technology. The 4.9 K-factor sprinkler is the first residential concealed sprinkler with the same cULus Listed flow rates for both ordinary and intermediate temperature ratings. As a result, you can now standardize on an intermediate temperature-rated sprinkler without sacrificing either performance or aesthetics.

Rated for ambient temperatures up to 150°F, the intermediate temperature VK494 model offers greater flexibility when positioning sprinklers around potential heat sources.

  • Flat plate concealed design with a nearly unlimited variety of custom color finishes, for a smooth ceiling look that doesn’t compromise aesthetics.
  • Available in both ordinary (155°F) and intermediate (200°F) temperature ratings.
  • Minimum achievable flow rates for 16' x 16', 18' x 18', and 20' x 20' coverage areas at both temperature ratings (0.05 gpm/sq. ft. density requirements).
  • Because VK494 ordinary and intermediate temperature flow rates are identical, you can standardize on the intermediate temperature models, simplifying inventory and reducing job site confusion.
