DESCRIPTION <br /> Viking Standard Response Dry Pendent Sprinklers are thermosensitive spray sprin- <br /> klers suitable for use in areas subject to freezing.The sprinklers are designed for dry <br /> systems and preaction systems where it is necessary to prevent water or conden- <br /> sation from entering the drop nipple before sprinkler operation. They may also be <br /> installed in spaces subject to freezing and supplied from a wet system in an adjacent <br /> heated area. Viking Standard Response Dry Pendent Sprinklers are available in <br /> various finishes and temperature ratings to meet design requirements. <br /> The special Polyester and Electroless Nickel PTFE (ENT) coatings have been <br /> investigated for installation in corrosive environments and are listed/approved as <br /> indicated in the approval charts. <br /> NOTE: When installed in some corrosive environments,the Polyester finish <br /> may change color.This natural discoloration over time is not in itself an indi- <br /> cation of corrosion and should not be treated as such.All sprinklers installed <br /> in corrosive environments should be replaced or tested as described in NFPA 25 <br /> on a more frequent basis. <br /> 2.
