Safety Video: Multi-Spectrum Infrared Detector Distinguishes Flames vs. Welding

A new Flame Detection Video from General Monitors (USA) demonstrates how the FL4000H Multi-Spectrum Infrared Flame Detector responds to flames 210 feet away, as well as its immunity to arc welding. The FL4000H Detector leads the industry in quickly detecting flames at the furthest distance, monitors them longer, and prevents nuisance false alarms.

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.

The NNT flame discrimination algorithm classifies the output signals from the MSIR sensor array as either fire or non-fire. The MSIR/NNT combination is highly immune to false alarms caused by lightning, arc welding, hot objects, and other sources of radiation.

Founded in 1961, General Monitors (an MSA company) is a global leader in gas and flame detection technologies. The company offers the industry’s widest selection of the most advanced fixed gas and flame sensing technologies. Whether the requirement is single-point gas and flame detection or a large multi-point integrated fire and gas system, General Monitors provides the solution with a single-point of responsibility for total project management.
