VK680 - QREC Concealed Horizontal Sidewall Sprinkler (K8.0)
Viking’s patented VK680 flat plate concealed sidewall sprinkler is cULus Listed as an extended coverage sprinkler for light hazard occupancies. The VK680 has a ¾ in (20 mm) NPT thread size and a K-factor of 8.0 (115). The sprinkler is cULus Listed for coverage areas up to and including 16' x 24' (4,9 x 7,3 m) and 18’ x 22’ (5,5 m x 6,7 m). Additionally, it has a temperature rating of 165°F (74°C) and can be installed up to 12” (305 mm) below the ceiling to better accommodate potential installation obstructions, such as light fixtures and crown moldings. The VK680 has a compact design, with a total length of only 2 inches (51 mm), allowing for easier installation in tight wall spaces. The cover plate for the VK680 commercial sidewall sprinkler is offered in a standard white finish and has a 135°F (57°C) temperature rating. Through Viking’s industry-leading custom paint program, Viking can apply virtually any brand and type of paint to the cover plate as well. Refer to technical datasheet for required design and installation criteria.
