Duct Smoke Detector

Duct Smoke Detector provides early warning of smoke by continually sampling air movement within heating and ventilation ducts in industrial and commercial premises. The duct smoke detector provides switching facilities to shut down associated fans to prevent the spread of smoke and toxic gases into other areas. DDH has been designed to operate in ventilation air ducts and combines an optical smoke detector, housing and sampling tube. DDH has been designed to maximise venturi airflow through the optical smoke detector.
