An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building. … See more Optical beam smoke detectors work on the principle of light obscuration, where the presence of smoke blocks some of the light from the beam, typically through either absorbance or light scattering. Once a certain percentage … See more Early examples of optical beam smoke detectors were prone to false alarms, which were caused by many different factors. Most commonly, the build-up of dust, dirt and other debris would lower the detection threshold for the detector, causing the system … See more Optical beam smoke detectors consist of at least one light transmitter and one receiver, which is photosensitive. The photosensitive receiver monitors light produced by the transmitter under normal conditions. In the absence of smoke, light passes from the … See more • Aspirating smoke detector • Automatic fire suppression • Carbon monoxide detector • Fire alarm • Fire sprinkler See more WebThe FIRERAY® 3000 End to End infrared Optical Beam Smoke Detector (OBSD) has been designed using the latest optical technology, incorporating modern industrial, electronic and software techniques.
