The Viking VK534 K11.2 Thermosensitive Pendent Sprinkler is engineered for installation in wet and dry fire suppression systems protecting light and ordinary hazard occupancies. Operating via a precision glass bulb thermal element, this extended coverage pendent sprinkler activates rapidly during fire events to deliver efficient water distribution across wide floor areas. Its extra-large orifice design produces required flow rates at lower operating pressures, optimizing hydraulic performance throughout the assembly.

This component satisfies governing NFPA standards for quick-response, extended-coverage fire sprinkler systems and thermal sensitivity requirements. It carries strict third-party agency testing validations, meeting UL listing criteria for safety and performance while maintaining Factory Mutual (FM) approval for commercial trade compliance.

  • Extended Coverage Design: Protects broader floor zones with fewer sprinklers while meeting hydraulic and hazard density requirements.
  • Extra-Large Orifice (K11.2): Delivers necessary water flow at reduced working pressures for efficient system demand management.
  • Glass Bulb Thermal Element: Provides reliable, quick-response activation during a thermal event.
  • Corrosion-Resistant Coating: Available with Nickel PTFE (ENT) coating options for installation in corrosive atmospheres.
  • Hazard Compatibility: Engineered for standard fire suppression systems in light and ordinary hazard occupancies.
