50 per Box 1.  Description Viking Standard/Quick Response Extended Coverage Ordinary Hazard (ECOH) Pendent Sprinkler VK572 is a thermosensitive glass bulb spray sprinkler with a 14.0 (202 metric*) nominal K-Factor. The sprinkler produces the flows required to meet Ordinary Hazard density requirements at lower pressures than 8.0 or 11.2 (115.2 or 161.4 metric*) K-Factor sprinklers. The glass bulb operating element and special deflector characteristics meet the challenges of quick response extended coverage standards. Viking EC/QREC Ordinary Hazard Sprinklers are available in various finishes and temperature ratings to meet design requirements. The special PTFE, Polyester, and Electroless Nickel PTFE (ENT) coatings can be used in decorative applications where colors are desired. In addition, ENT coating has been investigated for installation in corrosive atmospheres. See Approval Charts. The Viking VK572 Sprinkler may be ordered and/or used as an open sprinkler (glass bulb and pip-cap assembly removed) on deluge systems. 2.  listings and approvals cULus listed: Category VNIV FM approved: Class 2022 nyc approved: MEA 89-92-E, Volume 38 Refer to Approval Chart 1 and Design Criteria on pages 83t-u for cULus Listing requirements and refer to Approval Chart 2 and Design Criteria on page 83v for FM Approval requirements that must be followed
