Kidde - Edwards SD-T24 Air Sampling Tube 24 Inch

Product Description

The KIDDE - EDWARDS SD-T24 is a 24-inch air sampling tube designed for use with duct smoke detectors. It mounts into HVAC ductwork and draws an air sample into the detector housing, allowing the detection head to monitor for smoke particulates moving through the air stream. Licensed fire alarm technicians and HVAC professionals install this component as part of a listed duct detector assembly. The tube is sold as a single unit and is a direct accessory to compatible duct smoke detector housings in the KIDDE - EDWARDS product line.

Air sampling tubes are a required component in duct smoke detection systems installed in commercial and residential HVAC applications. This 24-inch tube is suited for medium to large duct widths where the sampling inlet must reach across the duct cross-section to capture a representative air sample. It pairs with the corresponding duct detector housing and is typically installed during new construction or retrofit fire alarm system upgrades in air handling units and fan coil systems.
