Viking C-1 Window Fire Sprinkler 3/4" NPT VK79 - Deluge System

The Viking Model C-1 Window Fire Sprinkler (VK79 series) is an open-type, non-automatic specialized sprinkler engineered for installation within deluge fire protection systems. It mounts directly above glass openings, walls, and architectural structures to establish a protective water curtain upon system activation. When connected detection systems trip, the deluge valve opens to supply all networked open sprinklers simultaneously, discharging a uniform flat spray pattern across window surfaces to absorb radiant heat and block flame propagation.

This deployment satisfies key life safety objectives for commercial and residential buildings requiring rigorous code compliance without sacrificing open architectural glazing. Operating in alignment with NFPA standards for deluge water spray systems, this component provides reliable defensive coverage across working pressures ranging from 7 psi up to 175 psi. The directional discharge design forms an overlapping water barrier that protects vulnerable envelope penetrations from structural fire escalation.

Key Features & Construction

• Material Construction: Forged from high-grade, corrosion-resistant brass to withstand demanding mechanical and environmental job site conditions.
• Spray Pattern: Engineered to discharge a directional, flat 180° fan-shaped water distribution curtain specifically targeted at glass and window assemblies.
• System Integration: Operates as a non-automatic open sprinkler designed strictly for simultaneous activation within dedicated deluge fire suppression assemblies.
• Pressure Range: Functions dependably across a broad operating window from 7 psi up to 175 psi working pressure.
• Connection Type: Features a 3/4" NPT threaded connection sized for precise commercial and residential piping configurations.

Technical Specifications & Compliance Table

Contractors must verify specific hydraulic calculations, spacing rules, and local Authority Having Jurisdiction (AHJ) mandates prior to final installation. Always review the official manufacturer cut sheets for complete design criteria.
