The Viking VK320 K5.6 Quick Response Horizontal Sidewall Sprinkler is a specialized fire protection device engineered for commercial and industrial installations where ceiling-mounted assemblies are structurally impractical. Installed horizontally on walls, it utilizes a quick-response fusible link mechanism to rapidly detect heat events, initiating prompt water discharge to suppress fires and minimize property damage.

Fully compliant with NFPA 13 installation guidelines, this sprinkler satisfies strict commercial life safety requirements for light hazard and specialized spaces. It is designed for seamless integration into both wet and dry pipe fire sprinkler systems, ensuring reliable performance across diverse commercial and industrial facility layouts.
