Product Description

Using a heat-activated fusible solder element, this automatic fire sprinkler opens when ambient temperatures reach 162F (72C), lowering ambient temperatures to reduce flashover and facilitate safe escape.

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, NFPA 13R, NFPA 13D and local fire code.
