The Viking VK320 K5.6 Quick Response Horizontal Sidewall Fire Sprinkler provides targeted fire suppression in commercial, industrial, and storage facilities where traditional ceiling-mounted configurations are impractical. Designed for installation along walls and structural bulkheads, this unit discharges water outward and downward in a quarter-spherical pattern to protect narrow corridors, aisles, and rooms with specialized architectural layouts. Its sensitive fusible element assembly activates rapidly upon heat detection, ensuring immediate fire containment in the earliest stages.

This sprinkler is engineered to satisfy strict design and installation mandates under NFPA 13 for standard sidewall spray sprinklers. It fulfills commercial code requirements for rapid-response life safety and property protection in light and ordinary hazard environments.

  • Fusible Element Assembly: Melts swiftly at a specific temperature to initiate fast-response water discharge.
  • Horizontal Sidewall Orientation: Mounts directly to walls to protect spaces where ceiling installations are unfeasible or aesthetically restricted.
  • High-Pressure Rating: Engineered for demanding high-pressure water networks with a maximum working pressure of 250 PSI (17 bar).
  • 5.6 K-Factor Orifice: Delivers precise, consistent water flow characteristics for hydraulic calculations.
  • Corrosion-Resistant Materials: Built with a brass frame casting and a phosphor bronze deflector for long-term operational durability.
