System Sensor ST-3 3' Sampling Tube

The System Sensor ST-3 Sampling Tube for Smoke Detector channels air from duct interiors toward compatible detection assemblies to support accurate monitoring of airborne particles within ventilation pathways. Measuring 3 feet in length, this tube directs airflow into the connected detector chamber, allowing air samples to pass through for condition assessment during circulation. Integrated into HVAC systems managing ducted airflow and ventilation control, it contributes to improved detection accuracy, consistent air sampling, reduced monitoring gaps, and dependable response across air-handling sections.
