Viking VK178 Quick Response Standard Dry Horizontal Sidewall Fire Sprinkler

The Viking VK178 Quick Response Standard Dry Horizontal Sidewall Fire Sprinkler is engineered for installation in dry, preaction, or wet pipe fire suppression systems protecting unheated spaces, narrow corridors, and areas where ceiling access is restricted. Its dry-pipe configuration isolates water behind a seal valve outside the freezing zone until thermal activation occurs, preventing ice blockages and pipe ruptures in cold environments.

This unit satisfies NFPA 13 installation requirements for dry horizontal sidewall applications and complies with UL and FM code mandates for commercial life safety systems. The quick-response mechanism detects elevated temperatures rapidly to initiate early water delivery, mitigating fire spread in restricted commercial environments.

• Dry Pipe Configuration: Keeps water out of the drop nipple until thermal activation, eliminating freeze damage risks in unheated environments.
• Quick Response Element: Detects heat swiftly to accelerate suppression action and minimize fire development.
• Horizontal Sidewall Orientation: Directs discharge spray outward and down along walls, optimized for narrow hallways and rooms lacking ceiling space.
• Heavy-Duty Build: Assembled with robust commercial-grade materials and corrosion-resistant finishes to endure harsh operating environments.
• Precision Deflector: Shapes water distribution for maximum coverage effectiveness along sidewall boundary areas.
