The Sampling Unit Detector detects smoke in the air traveling through heating, ventilation, and air conditioning ducts in commercial buildings. It was created to track smoke levels in air ducts with speeds ranging from 0.5 to 20 meters per second.
Enables air ducts to be monitored without requiring the detector to be mounted within the duct . Avoid sensor drift due to air-flow effects . Simple, easy to install design . Simple detector maintenance: there is no need to access the duct for calibration purposes . Extremely reliable; ASU has no moving parts
Sampling Unit should be installed in the center of a straight section of duct at least six times its width.
