The Omniguard Model 660 UV flame detector is designed to detect unwanted fires and output alarm information. The Model 660 senses ultraviolet radiation in the appropriate wavelength for fast detection of hydrocarbon and non-hydrocarbon fires. Available in two versions: one for standard industrial applications, and one suited for turbine enclosure and high temperature industrial applications.
