The Viking VK636 K11.2 ECLH PD CD is an extended coverage concealed pendent fire sprinkler engineered for commercial and industrial fire protection systems. Designed specifically for light hazard environments, this quick-response extra-large orifice (ELO) sprinkler integrates seamlessly into finished ceilings utilizing a concealed piping arrangement, providing a discreet profile while maintaining full operational capabilities in tight ceiling spaces measuring just 3.6 inches.
Fully compliant with NFPA 13 installation standards, this assembly satisfies rigorous commercial life safety requirements for extended coverage areas. By efficiently supporting larger suppression zones, it reduces the total quantity of sprinklers required across a facility layout while securing agency listings and approvals from both UL and FM for dependable, code-compliant performance.
- Concealed Pendent Design: Integrates flush with ceiling surfaces to maintain an unobtrusive architectural line.
- Extended Coverage Performance: Efficiently protects larger suppression areas to minimize total component counts per layout.
- Corrosion-Resistant Construction: Built from durable materials to ensure long-term operational reliability and reduced maintenance intervals.
- Compact Profile: Measures 3.6 inches to fit easily within restricted ceiling voids.
