The Viking MicrofastHP® Fixed Temperature Release is a fixed-temperature, heat-responsive device. It is designed for use on pilot line release systems to activate deluge and preaction systems. The fixed temperature release is equipped with a 3 mm glass bulb and is available in several finishes and temperature ratings to meet design requirements. The special Polyester and Teflon® coatings can be used in decorative applications where colors are desired. In addition, these two finishes are listed as corrosion-resistant finishes and provide protection against many corrosive environments. The fixed temperature release design closely resembles the Model M frame-style sprinkler design, but is easily identified by its special listing information plate. This is important when fixed-temperature releases are installed along with sprinklers below ceilings on concealed systems.
