System Sensor ST-5 Metal Sampling Tube for Duct widths 4'-8'

Optimize your duct smoke monitoring with the System Sensor ST-5 Metal Sampling Tube, engineered to deliver reliable air sampling for commercial HVAC and life-safety systems. This ST-series sampling tube is purpose-built for duct widths from 4' to 8', providing consistent intake across the duct when installed with the air inlet holes facing the airflow. The rugged metal construction offers durable performance for security and monitoring environments, and the recommended 2/3 duct coverage improves detector sensitivity and reduces nuisance alarms. For duct smoke systems using the DH400ACDCIHT detector, the ST-5 integrates seamlessly, enabling efficient surveillance and early smoke detection in critical facilities. Installers will appreciate the clear orientation guidance and the need to support tubes longer than 3 ft for secure, code-compliant mounting. Ideal for building managers, contractors, and integrators seeking dependable duct sampling for fire detection and security monitoring. Upgrade your duct smoke detection layout with the System Sensor ST-5—order now or contact our team for configuration and installation guidance.
