Overview

Tyco TY3551 Standard Response Concealed Pendent Fire Sprinkler delivers decorative, competitively-priced defense against fire in ordinary-temperature applications.This automatic fire sprinkler opens when ambient temperatures reach 155F (68C).

Choose from a factory-finished white cover plate, brushed chrome cover plate, polished chrome cover plate, or painted black cover plate that mounts flush to the ceiling for minimal visual impact. When temperatures near the ceiling reach 139F (59C), the soldered cover plate detaches, exposing the head of the Tyco TY3531 concealed pendent fire sprinkler, which activates when temperatures reach 155F (68C).

The Tyco Model TY3531 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 Standard Response Fire Sprinkler features a bronze frame, bronze deflector, and a beryllium-nickel seating assembly with PTFE.

With a maximum working pressure of 175 PSI FM or 250 PSI UL (12.1 BAR FM or 17.3 BAR UL), this pendent sprinkler hangs from above-ceiling piping behind a decorative cover plate. Pendent sprinklers direct the water stream downward against the deflector to distribute water in a circular or conical discharge pattern. and may be installed and used in accordance with NFPA 13 and local fire code.
