General Monitors - FL4000H Flame Detectors

The Model FL4000H is an advanced multi-spectrum infrared (MSIR) flame detector designed to provide superior false alarm immunity with the widest field of view. The FL4000H employs a multi-spectral optical IR sensing array with a sophisticated Neural Network Technology (NNT) system to reliably discriminate between actual flames and the vast majority of false alarm sources (such as arc welding). The FL4000H is designed to detect typical fires such as alcohol, n-heptane, gasoline, jet fuels and hydrocarbons. In addition, the FL4000H can see through dense smoke produced by diesel, rubber, plastics and lube oil fires.
