The Apollo Intelligent Base Mounted IR3 Flame Detector (55000-024APO) is designed to protect all indoor areas, even in dirty or smoky conditions where open flaming fires may be expected. The Apollo 55000-024 has 3 IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation.
