VK449 Residential Dry Horizontal Sidewall Fire Sprinkler

The Viking VK449 Residential Dry Horizontal Sidewall Fire Sprinkler is engineered to provide reliable fire suppression in cold, unheated environments where freezing temperatures threaten traditional wet pipe systems. Designed to install in residential applications such as garages, balconies, and exterior corridors, this dry-type assembly keeps water sealed away from the conditioned space until system activation occurs, eliminating pipe freezing and burst risks.

To satisfy the strict installation guidelines of NFPA 13D for residential fire protection systems, this unit utilizes a K4.0 heat-sensitive operating element that achieves rapid activation upon early fire detection. The horizontal sidewall configuration provides a discreet, low-profile fit along walls, maintaining interior aesthetics while delivering controlled water distribution to suppress flames and mitigate water damage in vulnerable areas.

Key Features & Construction

• Dry-Type Configuration: Keeps water sealed upstream of the unheated zone, preventing freezing and pipe failure during sub-zero weather.
• Horizontal Sidewall Orientation: Installs flush against walls for a low-profile footprint in residential spaces like garages and balconies.
• K4.0 Discharge Rate: Delivers controlled, early-suppression water flow optimized for residential hazard parameters.
• Corrosion-Resistant Materials: Built with robust metal components to endure harsh environmental conditions and secure long-term operational integrity.

Technical Specifications & Compliance Table

Contractors must verify specific local Authority Having Jurisdiction (AHJ) mandates, spacing parameters, and temperature ratings before proceeding with installation. Always consult the manufacturer's official technical data sheets to ensure exact engineering compatibility.
