The X3301 is a multispectrum infrared flame detector that uses patented signal processing to detect hydrocarbon fires while rejecting false alarm sources (hot CO₂, welding, sunlight, etc.). It provides very high-speed response and excellent detection range, making it one of the most trusted flame detectors in high-risk oil & gas and petrochemical facilities.
