Product Description

Using a heat-activated fusible metal assembly, this automatic fire sprinkler opens when ambient temperatures reach 162F (72C), drenching the area surrounding a fire to keep it in its place of origin.

The Senju Model ZN-UF has a 5.6 K-Factor and installs with 1/2" (12.7 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Standard Response Fire Sprinkler features a white finish, copper alloy body, bronze frame, copper alloy deflector, and PFTE gasket.

With a maximum working pressure of 175 PSI (12.1 BAR), this pendent sprinkler hangs from above-ceiling piping and may be installed and used in accordance with NFPA 13 and local fire code. Each Model ZN-UF sprinkler is made by Senju, Japan's largest manufacturer of fire-suppression products.
