Honeywell Silent Knight STS-10.0 Duct Sampling Tube

Product Description

The HONEYWELL SILENT KNIGHT STS-10.0 is a duct sampling tube designed for use with air duct smoke detection systems. It mounts inside ductwork to draw air samples into a connected smoke detector housing, allowing the detector to monitor airflow for combustion products. This component is classified as a fire control accessory and is sold as a single unit. Installation is performed by licensed fire alarm technicians and HVAC professionals working on life-safety systems in commercial and residential applications.

The STS-10.0 is intended for use with duct smoke detector installations where air sampling across the duct cross-section is required. It is suitable for duct widths in the 5 to 10 duct range, making it appropriate for medium to larger air-handling duct installations. Technicians select this tube when the duct dimensions require extended sampling reach to ensure adequate air sample collection across the full duct width.

Key Features

• Designed for duct smoke detector air sampling applications
• Sized for 5 to 10 duct width installations
• Sold individually as a single unit
• Classified as a fire control accessory for life-safety systems

Compatibility

Designed as an OEM-style replacement and accessory component for duct-mounted smoke detector assemblies requiring an air sampling tube sized for medium to larger duct widths.

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and the detector manufacturer instructions. Power down the fire alarm control panel or isolate the affected zone before servicing duct detector components. The sampling tube must be fully seated and oriented correctly within the duct to ensure proper airflow across the sampling ports. Verify system operation with a functional smoke test after installation per local authority having jurisdiction requirements.
