Viking VK156 Standard Response Dry Horizontal Sidewall Fire Sprinkler

The Viking VK156 Standard Response Dry Horizontal Sidewall Fire Sprinkler provides targeted fire suppression in commercial, industrial, and residential settings where traditional ceiling-mounted assemblies are impractical. Designed specifically for installation in dry pipe or preaction fire protection systems, this unit features a specialized dry barrel configuration that prevents water accumulation in exposed, unheated piping runs. This mechanism eliminates freeze damage in unheated environments such as cold storage facilities, warehouses, and exterior projections until the heat-activated element operates.

This dry horizontal sidewall sprinkler satisfies the installation requirements outlined in NFPA 13 for specialized hazard areas and restricted spatial configurations. By mounting directly to walls, the assembly delivers precise water distribution in narrow hallways, corridors, and rooms lacking overhead clearance, ensuring code-compliant life safety and property protection.

• Dry Pipe Technology: Keeps water out of exposed, unheated piping to prevent freeze-ups in cold storage and exterior environments.
• Horizontal Sidewall Configuration: Mounts directly to walls for targeted suppression in areas lacking traditional overhead clearance.
• Durable Construction: Built from high-grade metals with corrosion-resistant coatings to withstand harsh commercial and industrial conditions.
• Standard Response Thermal Element: Engineered for predictable activation timing during fire events to optimize suppression performance.

Contractors must verify specific spacing, obstruction, and temperature rating requirements with the local Authority Having Jurisdiction (AHJ) prior to installation. Always consult the manufacturer's official technical data sheets for complete installation guidelines, trim dimensions, and torque specifications.
