The Simplex 4098-9858 is a 97-inch duct sampling tube. It draws air from HVAC ductwork into a compatible Simplex duct smoke detector housing.
Specifically, the sampling tube spans the full width of the duct. As a result, the detector pulls a representative air sample from across the entire airflow, not just one corner.
Why Tube Length Matters
Correct tube length is critical to proper duct detector operation. Therefore, the tube must match the duct width so the inlet holes line up with the moving airstream.
The 4098-9858 is sized for duct widths up to 97 inches. In addition, the inlet holes along the tube ensure even sampling across the duct cross-section.
Compatible Duct Housings
The Simplex 4098-9858 sampling tube is intended for use with Simplex 4098-series duct smoke detector housings, including the 4098-9755 and related models.
