Senju CN-RES Residential Fast Response Concealed Pendent Fire Sprinkler delivers decorative, affordable defense against fire in residential occupancies such as homes and apartments. Using a heat-activated compressed fusible solder, this automatic fire sprinkler opens when ambient temperatures reach 162F (72C), reducing the likelihood of flashover and facilitating safe evacuation.

Low-profile cover plates mount flush to the ceiling and are available with a painted wood finish, metallic finish, or simple colors. Custom-colored cover plates are available by special order when ordering in quantities larger than 100 units . When temperatures near the ceiling reach 140F (60C), the soldered cover plate detaches, exposing the head of the Senju CN-RES concealed pendent fire sprinkler, which activates when temperatures reach 162F (72C).

The Senju Model CN-RES has a 4.9 K-Factor and installs with 1/2 in. (12.7 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Residential Fast Response Fire Sprinkler features a copper alloy body, bronze frame, phosphor bronze deflector, and PTFE gasket.
