Beam detector are used for detection of smoke in remote areas.

This works on the principle of light obscuration. When the transmitted light percentage is blocked by the smoke the detector activates and sends signal, It uses beam light to project across an area to monitor for smoke emitted by an incipient fire. When the smoke is present in the beam path.
