Optical beam smoke detectors are used to provide wide area smoke detection. These are usually used in situations where it is impractical, inappropriate or not cost effective (installation, wiring & maintenance) to use traditional point-type detectors. It also enables coverage of a large area. Optical beam smoke detectors are also ideally suited for situations that might include high ceilings, dusty and dirty environments, or environments that experience temperature extremes. The optical beam smoke detector works on the principle of light obscuration. The photosensitive element of the optical beam smoke detector sees light produced by the transmitter in a normal condition. The receiver is calibrated to a preset sensitivity level based on a percentage of total obscuration. There are two general types of optical beam smoke detector, such as projected and reflective. The type used will be dictated by the installation & environment conditions and constraints.
