Tailor made to detect hydrocarbon flames outside the visible spectrum, the FGard UVIR flame detector is an explosion proof ultraviolet-infrared flame detector designed to provide elite detection of hydrocarbon fires.
The Fgard UVIR incorporates the latest IR flame detection algorithms to prevent the risk of false alarms, and with three different sensitivity settings, you can customise the sensors for your space and needs.
Designed to operate in all conditions, the microprocessor controlled heated optics ensure continuous operation even in harsh weather environments at risk of snow, ice, and condensation.
With advanced optical verification, an automatic test verifies cleanliness of the lens and electronic circuitry to ensure the detector is always primed for optimal performance, requiring no reflector optical check. Plus, its large optical surface minimises the risk of false alarms, so you can respond efficiently with confidence to any alarm.
False Alarm Immunity
- Utilises the latest IR flame detection algorithms to ensure maximum false alarm immunity
- Perfect for hazardous environments where false alarms are unacceptable
- Independently tested to demonstrate it can detect a hydrocarbon fuel pan fire at over 130 ft in less than 5 seconds
Adjustable Sensitivity Levels
- Choice of three different sensitivity settings for selection of the most appropriate level for your specific application
- Provides application flexibility and ensures detectors do not cross vote
Advanced Optical Verification
- Automatic test verifies cleanliness of the lens and electronic circuitry
- No need for reflector optical checks
- Large optical surface results in far fewer false alarms
- Intelligent heated optics mean no risk of condensation, ice or water on the lens for unimpaired performance in all weather
