The Viking VK300 K5.6 Quick Response Upright Fire Sprinkler is engineered for rapid heat detection and targeted water delivery in commercial, industrial, and light-hazard fire suppression assemblies. Installed in an upright orientation, this component mounts directly onto overhead piping networks—including wet pipe, dry pipe, pre-action, and deluge systems—to protect ceilings and wide open-span structural spaces from rapid fire propagation.
This sprinkler satisfies strict life safety mandates by complying directly with NFPA 13 design and installation standards for commercial fire protection systems. Operating via a finely calibrated, thermosensitive glass bulb, the unit swiftly detects initial thermal signatures to initiate immediate discharge, fulfilling code-required rapid suppression parameters in high-risk environments.
