DatasheetThe FGard IR3 delivers superior performance in the detection of hydrocarbon fires. The FGard IR3 utilises the latest IR flame detection algorithms to ensure maximum false alarm immunity.
The FGard IR3 has been independently tested to demonstrate it can detect a hydrocarbon fuel pan fire at nearly 200 feet in less than 5 seconds.
Multi spectrum IR
60 metre flame detection range – Will detect all Hydrocarbon fires which means no condensation forming on the window, improving reliability and performance across temperature.
Fast detection time
Responds in less than 5 seconds to 0.1m² fire at 60 metres
Heated optics
Intelligent heated optics – No condensation / ice / water
Advanced optical verification – No reflector
Automatic test verifies cleanliness of the lens and electronic circuitry. No reflector optical check and large optical surface results in far fewer false alarms.
