Edwards SD-T24. 24-inch Sampling Tube.

Edwards SD-T24 24-inch Sampling Tube

The Edwards SD-T24 24-inch Sampling Tube is designed for use in HVAC duct smoke detection systems. It allows duct-mounted smoke detectors to draw a consistent air sample across medium-to-large ducts, ensuring early detection of smoke and compliance with fire protection codes. Suitable for ducts up to 24 inches wide, this sampling tube offers a balance between reach and ease of installation.

When properly installed, the SD-T24 supports fast and reliable smoke detection in commercial air handling systems.

Balanced Airflow Sampling for Better Detection

The SD-T24 includes a row of precisely drilled holes that pull air from across the full width of the duct. These openings allow the attached detector to receive a representative sample of air, improving its ability to sense smoke or other combustion products quickly. Because of this balanced airflow, the system can react faster to potential fire conditions.

In environments where HVAC systems vary in pressure or flow rate, consistent sampling becomes especially important. The SD-T24 helps maintain that consistency, even during fluctuating system conditions.

Rugged Design and Easy Installation

Made from durable, corrosion-resistant material, the SD-T24 performs reliably in both standard and demanding HVAC applications. It resists damage from vibration, temperature changes, and airflow pressure. This durability contributes to long-term accuracy and minimizes the need for maintenance or replacement.

Installation is straightforward. The tube slides into the detector housing and locks in place using standard hardware. A sealed end cap prevents airflow from escaping and ensures proper pressure for accurate sampling. Installers benefit from the quick setup and dependable fit with Edwards detector models.

Ideal for Commercial and Institutional Projects

This 24-inch sampling tube is a practical solution for schools, office buildings, healthcare centers, and similar facilities with mid-size ductwork. It allows system designers to meet code requirements without overcomplicating the installation. Whether for new construction or a retrofit, the SD-T24 integrates easily into most system designs.

The Edwards SD-T24 24-inch Sampling Tube delivers efficient and consistent airflow sampling in ducts up to 24 inches wide. Its sturdy construction, reliable performance, and compatibility with Edwards smoke detectors make it a trusted solution in fire alarm system installations. For contractors and designers who value both accuracy and ease of use, the SD-T24 offers dependable results in a wide range of applications.
