The General Monitors FL4000H Multi-Spectral Infrared (MSIR)/Neural Network Technology (NNT) Flame Detector sets a new industry standard for performance, reliability, and value. The FL4000H is the industry’s first MSIR/NNT Flame Detector designed to operate at longer range with a wider field of view and at higher accuracy for superior false alarm immunity. Combining a precision multi-spectral IR sensing array with highly intelligent neural network processors, the FL4000H reliably discriminates between actual flames and nuisance false alarm.
