Product Description

Viking XT1 Quick Response Brass Upright Fire Sprinkler provides reliable and easily-installed protection against fire, and is perfect for ordinary-hazard commercial and industrial occupancies, such as hotel lobbies, office buildings, churches, and restaurants. Using a 3mm glass bulb, this automatic fire sprinkler opens when ambient temperatures reach 155F (54C), supporting rescue and evacuation efforts by lowering ambient temperatures. This sprinkler replaces and improves upon the Viking VK350, with a reduced size (as short as 1 9/16" when installed), a corrosion-resistant deflector, a smooth and finish-ready frame, and a laser-etched deflector.

Viking XT1 Quick Response Brass Upright Fire Sprinkler has an 8.0 K-Factor and installs with 3/4" NPT thread, used in fire sprinkler systems throughout the United States. Each quick response head features a brass body, stainless steel deflector, and nickel alloy spring. This 155F (68C) temperature rating strikes a balance between a fire sprinkler that activates too soon, causing accidental discharge, and too late.

With a maximum working pressure of 175 PSI (12.1 BAR), this upright sprinkler installs deflector-up to prevent debris and ice accumulation and may be installed in accordance with NFPA 13 and local fire codes. Each XT1 sprinkler is made by Viking, a global leader in fire protection manufacturing for nearly 100 years.

This product is UL & FM approved and appropriate for use in fire protection systems when accepted by the authority having jurisdiction. Pendent sprinklers direct the water stream downward against the deflector to distribute water in a hemispherical spray pattern. In accordance with NFPA 13, a higher temperature rating may be required when installing a fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops.
