DH100LP Duct Detector

2 Wire 12/24V Photo Duct Detector


The DH100 Series Low-Flow photoelectric duct smoke detectors are capable of sensing smoke in air velocities from 0.5 to 20 m/sec. The Innovair range features low-flow technology that enables duct smoke detection throughout a broad range of airflow environments. Many difficult to solve HVAC applications occur in low airflow ducts where reliable smoke detection is critical. Innovair low-flow technology can detect smoke at air speed velocities of 30 meters per minute or greater, while continuing the same reliable performance to 1200 meters per minute. The DH100 Series Detector samples air currents passing through a duct and gives dependable performance for shutdown of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke and fire gases through the protected area.
