DESCRIPTION <br /> The Viking Micromatic® Standard Response Upright VK100 Sprinkler is a small, ther- <br /> mosensitive, glass-bulb spray sprinkler available in several different finishes and tem- <br /> perature ratings to meet design requirements. The special Polyester and Electroless <br /> Nickel PTFE (ENT) coatings can be used in decorative applications where colors are Ao <br /> desired. In addition, these coatings have been investigated for installation in corrosive <br /> atmospheres and are listed/approved as corrosion resistant as indicated in the Approval <br /> Charts.(Note: FM Global approves the ENT coating as corrosion resistant.FM Global has <br /> no approval classification for Polyester coatings as corrosion resistant.) <br /> Viking standard response sprinklers may be ordered and/or used as open sprinklers (glass <br /> bulb and pip cap assembly removed)on deluge systems. Refer to Ordering Instructions. <br /> 2.
