The EC5000R beam detector features a transmitter and receiver in a single enclosure. The transmitter emits an invisible, reflected infrared light beam that is detected by the receiver and analyzed. Smoke in the beam path will reduce the received infrared light proportionally to the density of the smoke. The detector analyzes this and initiates an alarm condition when a predetermined level of obscuration is reached. The EC5000R System features advanced innovations such as auto-alignment, which indicates the optimal location of the reflector by means of an integrated laser. Once installed, the system automatically steers and maintains the beam to the optimum position for reliable performance.
