Viking Standard Response Dry Pendent Sprinklers are thermosensitive spray sprinklers suitable for use in areas subject to freezing. The sprinklers are designed for dry systems and preaction systems where it is necessary to prevent water or condensation from entering the drop nipple before sprinkler operation. They may also be installed in spaces subject to freezing and supplied from a wet system in an adjacent heated area. Viking Standard Response Dry Pendent Sprinklers are available in various finishes and temperature ratings to meet design requirements.

The special Polyester and Electroless Nickel PTFE (ENT) coatings have been investigated for installation in corrosive environments and are listed/approved as indicated in the approval charts.
