Viking's Mirage® Model VK538 EC/QREC OH-ELO Concealed Pendent Sprinkler is cULus Listed for OH-1 and OH-2 occupancies, and designed for installation on concealed pipe systems where the appearance of a smooth ceiling is desired. With a K-factor of 11.2 (161), the sprinkler produces flows required to meet Ordinary Hazard density requirements at lower pressures than 5.6K or 8.0K sprinklers. The fusible operating element and special deflector characteristics meet the challenges of quick response extended coverage standards. The K-factor of 11.2 (161) makes the VK538 well suited for systems requiring higher water densities, as well as situations where the available water pressure is limited. Potential applications include casinos, hotel atriums, retail environments, libraries, automotive showrooms, and shopping malls. The VK538 is Listed for coverage areas as large as 20 x 20 ft. (6.1 x 6.1 m) and has required flows and pressures that are less than or equal to most non-concealed sprinklers for OH occupancies. Refer to technical datasheet for required design and installation criteria.
