IR3 Flame Detectors

Details

The IR3 flame detectors are utilize advanced microprocessor technology for precise electronic signal analysis. These detectors require the Infrared sensors to surpass their alarm threshold balance, with an additional flame flicker-frequency analysis criterion for enhanced detection. Offering robust false alarm rejection capabilities, including Arc Welding (>3m) and chopped sunlight or halogen lights, while still effectively detecting real fires, they ensure reliable performance. With a dynamic delay time of 4-8 seconds to prevent unwarranted alarms and suitability for detecting light and heavy Hydrocarbon fires, they offer versatile protection. Regular self-tests and availability of a Test Lamp for inspections ensure optimal sensor and electronics functionality.
