OmniGuard 660 – UV Flame Detector

The Omniguard® model 660 UV flame detector is designed to detect fires and output appropriate alarm information. The model 660 senses ultraviolet radiation in the appropriate wavelength for extremely fast fire detection. The model 660 will sense both hydrocarbon and non-hydrocarbon fires, a technology which has proven itself over decades of reliable service.

The model 660 is available in two versions, one for standard industrial applications with a maximum operating temperature of 85°C, and a second which is capable of operating at a maximum sustained temperature of 125°C. This version is especially well suited for turbine enclosure and high temperature industrial applications. Both versions come with an automatic self-test function to monitor the detector’s ability to sense fires and report a fault condition when impaired. Typical applications for the Omniguard® 660 model are turbine enclosures, powerplants, compressor stations, LPG facilities, LNG facilities and engine test cells.
