Product Description

Senju RC-RES Residential Fast Response Concealed Pendent Fire Sprinkler delivers decorative, affordable defense against fire in intermediate hazard residential occupancies such as homes, apartments, dormitories, and hotels. Using a heat-activated compressed fusible solder, this automatic fire sprinkler opens when ambient temperatures reach 175F (79C), 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 (a $325 paint set-up fee applies). When temperatures near the ceiling reach 140F (60C), the soldered cover plate detaches, exposing the head of the Senju RC-RES concealed pendent fire sprinkler, which activates when temperatures reach 175F (79C).

The Senju Model RC-RES has a 3.7 K-Factor and installs with 1/2" (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, phosphor bronze deflector, and PTFE gasket.

To order the Senju RC-RES with custom cover plates, contact us at 888.361.6662 or fill our our contact form.

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 RC-RES sprinkler is made by Senju, Japan's largest manufacturer of fire-suppression products.

This product is UL-listed, and appropriate for use in fire protection systems when accepted by the authority having jurisdiction.
