FL500 UV/IR Flame Detector

The performance of the FL500 UV/IR Flame Detector has been approved by Factory Mutual (FM) for hydrocarbon fires. Every two minutes, the integrated self-check function with continuous optical path monitoring performs an optical and electrical check to ensure that the optical path is clear and that the electronic circuits are working properly.
