System Sensor ST-3 Tube ensuring a low-impedance path andThe System Sensor ST 3 is a professional grade metal duct sampling tube engineered for precise air monitoring in commercial and industrial HVAC systems. Designed for duct widths from 2 ft to 4 ft, this 3 foot rigid tube facilitates the intake of air into the detection chamber to ensure rapid smoke identification. This duct smoke detector accessory is specifically built for integration with legacy duct smoke detector models, including the DH100, DH200,
