Viking VK190 Dry Concealed Pendent Fire Sprinkler Standard Response.

Protect your facility from freezing hazards while keeping ceilings clean with the Viking VK190 Standard Response Dry Concealed Pendent Fire Sprinkler. This component installs in dry, pre-action, or wet fire suppression systems, specifically protecting unheated areas like attics, parking garages, and exterior canopies where trapped water could otherwise freeze.

Engineered to comply with NFPA 13 standards, this sprinkler satisfies critical commercial safety requirements for properties requiring hidden fire suppression hardware. The glass bulb activation mechanism expands and shatters when exposed to heat, releasing water through a standard K-factor 5.6 orifice to control active fires.

• Brass Construction: High-grade brass resists rust and environmental wear in varied climate conditions, protecting long-term system integrity.
• Concealed Pendent Design: Sits flush with the ceiling behind a domed cover plate that detaches automatically during a fire.
• Vertical Adjustment: Threaded adapter design allows up to ½ inch (13 mm) of vertical adjustment during installation.
• Standard Response: Standard orifice and response design provide dependable water discharge when triggered.
• Flexible Installation: Push-on, thread-off cover lets you install components before ceiling construction finishes.

Always verify local Authority Having Jurisdiction (AHJ) requirements and consult manufacturer technical cut sheets prior to beginning your installation.
