Optical beam smoke detector (reflector) Generic optical beam smoke detector with transmitter and reflector. Single-ended beam smoke detector. The continuous infrared gas detection beam (projected up to 650' in length) helps to address the "area coverage" issue by enhancing the probability that the gas release will actually encounter a gas detector, significantly improving the likelihood of detection. Highly reliable, long-lasting ultraviolet (UV) receptor tube. The designer must evaluate a number of considerations to . This means that there is a region in the detector from the hadron beam towards the center of the detector in which there is no activity from the hadronic final state. The code discusses a number of detector types that a designer can use, including linear projected beam smoke detectors, duct smoke detectors and aspirating smoke detectors. This is achieved due to the beam detectors using the obscuration method, which detects fire due to smoke particles obscuring the infra-red light along the sensing path. tion under flat ceilings, providing a total area coverage of 19,800 square feet (60 feet x 330 feet), or 1844 square metres (18.3 x 100.6 m).
