Viking Mirage® EC/QREC ELO Concealed Pendent Sprinkler VK538 is a thermo-sensitive solder link spray sprinkler designed for installation on concealed pipe systems where the appearance of a smooth ceiling is desired. With a K-factor of 11.2, the sprinkler produces flows required to meet Ordinary Hazard density requirements at lower pressures than 5.6K or 8.0K sprinklers. The fusible operat-ing element and special deflector characteristics meet the challenges of quick response extended coverage standards. Sprinkler VK538 has cULus Listings as both standard and quick response.

The sprinkler is pre-assembled with a threaded adapter for installation with a low-profile cover assembly that provides up to ½” (12.7 mm) of vertical adjustment. The two-piece design allows installation and testing of the sprinkler prior to instal-lation of the cover plate. The “push-on”, “thread-off” design of the concealed cover plate assembly allows easy installation of the cover plate after the system has been tested and the ceiling finish has been applied. The cover assembly can be removed and reinstalled, allowing temporary removal of ceiling panels without tak-ing the sprinkler system out of service or removing the sprinkler.
