Product Description

Victaulic V2740 Residential Fast Response Chrome Pendent Fire Sprinkler delivers reliable and easily-installed protection against fire in ordinary hazard residential occupancies such as homes, apartments, dormitories, and hotels. Using a heat-activated 3mm glass bulb, this automatic fire sprinkler activates when the surrounding air reaches 155F (68C), lowering ambient temperatures to reduce flashover and facilitate safe escape.

The Victaulic Model V2740 has a 4.9 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 chrome finish, die-cast brass frame, bronze load screw, bronze deflector, a bronze pip cap, and a PTFE-taped seal. The frame is cast with a hex-shaped wrench boss to make installation and tightening from many angles easy.

This 155F (68C) temperature rating strikes a balance between a fire sprinkler that activates too soon, causing accidental discharge, and too late. 155F (68C) Residential Fast Response Fire Sprinklers are preferred for use in theaters, restaurants, and other gathering spaces where human safety is the first priority. The Victaulic Model V2740 is also perfect for use in animal shelters, agricultural and food processing facilities, and fairgrounds.

With a maximum working pressure of 175 PSI (12.1 BAR), this pendent sprinkler mounts to ceiling pipes and may be installed and used in accordance with NFPA 13, NFPA 13R, NFPA 13D and local fire code. Each Model V2740 sprinkler is made by Victaulic, a piping-industry manufacturer and trusted producer of fire protection products since 1919.

This product is UL-listed, and appropriate for use in fire protection systems when accepted by the authority having jurisdiction. In accordance with NFPA 13, a higher temperature rating may be required when installing a residential fast response fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops.
