Product Description

Victaulic V3405 Standard Response Brass Pendent Fire Sprinkler delivers reliable and easily-installed protection against fire in ordinary hazard commercial occupancies such as universities, auditoriums, churches, and parking garages. Using a heat-activated 5mm glass bulb, this automatic fire sprinkler activates when the surrounding air reaches 155F (68C), drenching the area surrounding a fire to keep it in its place of origin.

The Victaulic Model V3405 has a 8.0 K-Factor and installs with 3/4" (20 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Standard Response Fire Sprinkler features a brass finish, die-cast brass frame, bronze load screw, bronze deflector, and a beryllium nickel spring with 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) Standard Response Fire Sprinklers are preferred for use in theaters, restaurants, and other gathering spaces where human safety is the first priority. The Victaulic Model V3405 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 and local fire code. Each Model V3405 sprinkler is made by Victaulic, a piping-industry manufacturer and trusted producer of fire protection products since 1919.

This product is UL & FM approved 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 standard response fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops.
