Omniguard Model 660 UV Flame Detector

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

The Omniguard model 660 is available in two versions, one for standard industrial applications where a maximum operating temperature of 85°C is the norm, 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 are available with an automatic self-test function to monitor the detector’s ability to sense fires and report a fault condition when impaired.

 Key Features:

  • Available in special high temperature version (-40°C to +125°C)
  • All inclusive three-year warranty on parts and labor
  • Widest field of view in the industry (120°)
  • Robust, weatherproof enclosure for indoor or outdoor applications
  • FM, CSA, IECEx and ATEX approved
  • Improved, advanced through-the-lens diagnostic self-test
  • Long range detection
  • Self-contained, explosion-proof enclosure
  • Economical no-test version available
  • Field configurable relays and sensitivity
  • State-of-the-art microprocessor control
  • High intensity, localized indication of fire or fault
