Product Description

Senju RC-QR-EC Quick Response Concealed Pendent Fire Sprinkler delivers decorative, affordable defense against fire in light hazard commercial occupancies such as universities, auditoriums, churches, and parking garages. Using a heat-activated fusible metal assembly, this automatic fire sprinkler opens when ambient temperatures reach 162F (72C), reducing the likelihood of flashover and facilitating safe evacuation. With coverage areas from 16 square feet (4.9 square meters) to 20 square feet (6.1 square meters), the extended coverage design increases the chance of a successful evacuation in case of fire.

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-QR-EC concealed pendent fire sprinkler, which activates when temperatures reach 162F (72C).

The Senju Model RC-QR-EC 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 Quick Response Fire Sprinkler features a copper alloy body, phosphor bronze deflector, and PFTE gasket.

To order the Senju RC-QR-EC 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 and local fire code. Each Model RC-QR-EC 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.
