Viking VK2523 Standard Response Dry Sidewall Sprinkler

The Viking VK2523 Standard Response Dry Sidewall Sprinkler is engineered for commercial fire protection in ordinary hazard areas vulnerable to freezing conditions, such as warehouses, loading docks, and exterior corridors. Designed for installation along sidewalls where traditional overhead piping is impractical, this unit features a dry barrel design that restrains water from entering the assembly until thermal activation occurs, effectively eliminating freeze damage risks in unheated or semi-exposed environments.

This assembly satisfies strict NFPA 13 standards for code-compliant fire suppression installations in ordinary hazard environments. It meets UL Listed and FM Approved criteria to ensure dependable operational readiness and reliable water delivery during active fire events.
