Overview
Senju CN-QR Quick Response Concealed Pendent Fire Sprinkler delivers decorative, competitively-priced defense against fire in intermediate hazard commercial occupancies such as hotel lobbies, office buildings, churches, and restaurants. Using a heat-activated soldered fusible link assembly, this automatic fire sprinkler opens when ambient temperatures reach 205F (96C), reducing the likelihood of flashover and facilitating safe evacuation.
Low-profile cover plates mount flush to the ceiling and are available in a factory-finished white, brushed chrome, grey white, ivory, beige, terra brown, jet black, or brushed brass. When temperatures near the ceiling reach 139F (59C), the soldered cover plate detaches, exposing the head of the Senju CN-QR concealed pendent fire sprinkler, which activates when temperatures reach 205F (96C).
The Senju Model CN-QR has a 5.6 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 Quick Response Fire Sprinkler features a copper alloy body, a phosphor bronze deflector, and a bronze frame providing 3/8 in. (9.53 mm) vertical adjustment for easy installation.
