VK2843, VK2883, VK2923 - Quick Response Ordinary Hazard Dry Horizontal Sidewall Fusible Link Sprinklers (K8.0)

Quick Response Ordinary Hazard Dry Horizontal Sidewall Fusible Link Sprinklers (K8.0)

Viking Quick Response Ordinary Hazard Dry Horizontal Sidewall Fusible Link 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 supplied from a wet system in an adjacent heated area. The large orifice dry sidewall sprinkler allows greater flows at lower pressures than standard orifice sprinklers. The newly desinged deflector carries an expanded approval for installation from 4” to 12” below the ceiling, allowing additional flexibility when installing sprinklers near crown moldings or other obstructions.  Viking Quick Response Ordinary Hazard Dry Horizontal Sidewall 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 atmospheres and are cULus listed as corrosion resistant as indicated in the Approval Chart.  Refer to technical data sheet for design and installation requirements. Dry Sprinkler Order Form(opens in a new window)
