Product Description

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

This Residential Fast Response Fire Sprinkler features a black finish, DZR brass frame, phosphor bronze deflector, and nickel/PTFE spring assembly.

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