System Sensor ST-10 Metal Sampling Tube for Duct widths 8'-12'

Ensure dependable duct smoke detection with the System Sensor ST-10 metal sampling tube, engineered for precise air sampling in 8'-12' duct widths. This sampling tube, compatible with standard duct smoke detector systems, delivers consistent smoke monitoring and helps security and fire teams detect events early before they escalate. Constructed from robust metal, the ST-10 stands up to HVAC conditions for long-term reliability and lower lifecycle costs. Key installation best practices—place the tube with the series of air inlet holes facing the airflow and extend the tube at least two-thirds across the duct—maximize detection performance and reduce nuisance alarms. For lengths over 3 ft, support the tube at the opposite end of the detector to maintain alignment and compliance. Ideal for commercial HVAC, surveillance-integrated fire detection, and building security monitoring, the ST-10 sampling tube simplifies integration with existing duct smoke detectors and control systems. Add the System Sensor ST-10 to your next installation to enhance duct smoke monitoring and overall facility protection.
