Detectors 129
Detectors 129 : Particle Detectors: (4.11) Flame Detector: (1) Optical Types: (1. 7) Visible Sensors: In some detectors a sensor for visible radiation is added to the design in order to be able to discriminate against false alarms better or improve the detection range. Example: UV/IR/vis, IR/IR/vis, IR/IR/IR/vis flame detectors
