VK110 K5.6 Standard Response Fusible Link Pendent Fire Sprinkler

The VK110 K5.6 Standard Response Fusible Link Pendent Fire Sprinkler delivers targeted water suppression for commercial, retail, and light-industrial ceiling installations. Designed for wet fire sprinkler assemblies, this downward-facing pendent unit utilizes a thermosensitive fusible link that reacts reliably to specific heat thresholds while preventing false activations.

Engineered to satisfy strict code requirements, this sprinkler is UL Listed and FM Approved in direct accordance with NFPA 13 standards for standard hazard settings. Facility managers and trade contractors rely on its precise thermal response and calibrated orifice to maintain full compliance, protect building occupants, and minimize property damage during fire emergencies.

• Discharge Coefficient: Features a calibrated K5.6 orifice that provides a controlled flow rate tailored for standard hazard environments, optimizing your water supply use.
• Thermal Activation: Incorporates a thermosensitive fusible link that responds promptly to fire conditions while reducing accidental trips.
• Downward Pendent Design: Directs water flow straight down to maximize ceiling-area coverage across open commercial layouts.
• Thread Connection: Utilizes a standard 1/2" NPT thread to simplify retrofits and integrate smoothly into existing piping systems.
• Corrosion-Resistant Build: Built with rugged, corrosion-resistant materials to withstand humid facilities and reduce replacement frequency.

Contractors must verify local Authority Having Jurisdiction (AHJ) guidelines and review manufacturer data sheets prior to system layout and installation.
