UV Infrared Detector with false alarm immunity.
The FL500-H2 is an Ultraviolet / Infrared flame detector designed specifically to detect hydrogen (H2) fires. The FL500-H2 optical flame detector monitors for radiation emitted by a hydrogen flame in both the ultraviolet (UV) and infrared (IR) spectral ranges. This UV/IR combination provides a fast response time and increased false alarm immunity against sources of radiation for reliable protection.
