Viking XT1 Quick Response Brass Pendent Fire Sprinkler provides reliable and easily-installed protection against fire, and is perfect for high-hazard commercial and industrial occupancies, such as factories, refineries, and chemical plants. Using a 3mm glass bulb, this automatic fire sprinkler opens when ambient temperatures reach 286F (127C), supporting rescue and evacuation efforts by lowering ambient temperatures. This sprinkler replaces and improves upon the Viking VK352, with a reduced size (as short as 13/16" when installed with the NP-1 recessed escutcheon), a corrosion-resistant deflector, a smooth and finish-ready frame, and a laser-etched deflector.
Viking XT1 Quick Response Brass Pendent 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.
With a maximum working pressure of 175 PSI (12.1 BAR), this pendent sprinkler hangs from above-ceiling piping 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.
