The Fgard IR3 delivers superior performance in the detection of hydrocarbon fires, using the latest infrared (IR) flame detection algorithms to minimise the risk of false alarms.
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, maximising the time you have to respond in an emergency.
Its multi-spectrum IR will detect all hydrocarbon fires with intelligent heated optics, meaning no condensation, ice or water affecting detection. Plus, its advanced optical verification checks cleanliness of the lens and electronic circuitry, meaning no reflector optical check is needed, and a large optical surface results in far fewer false alarm
