Honeywell Silent Knight SD505-T10 Sampling Tube

Product Description

The HONEYWELL SILENT KNIGHT SD505-T10 is a sampling tube designed for use with duct smoke detection systems. Sampling tubes draw air from inside HVAC ductwork into the detector housing, allowing the detector to sense smoke or combustion products moving through the air stream. This component is a field-installed accessory that pairs with compatible duct detector housings. Licensed fire alarm or HVAC technicians typically handle installation as part of a duct detection assembly. Note that this part has been discontinued by the manufacturer, so availability may be limited to existing inventory.

The SD505-T10 sampling tube is intended for duct detector installations in commercial and light-commercial HVAC systems. Duct detectors are commonly installed in air-handling units and main supply or return ducts where early smoke detection is required by code. This tube fits into the inlet or exhaust port of a compatible duct detector housing and is sized to span the duct opening, pulling an air sample across the sensing chamber. Consult current project documentation and local fire codes for approved substitutes given the discontinued status of this part.

Installation Notes

Installation of duct smoke detectors and associated sampling tubes should be performed by a licensed fire alarm contractor or qualified HVAC technician in accordance with NFPA 72 and local authority-having-jurisdiction requirements. Power down and de-energize the fire alarm control panel circuit and the associated HVAC unit before servicing. Do not install the sampling tube in a duct that operates outside the velocity range specified in the detector housing documentation. Verify all connections and test detector response per the applicable fire alarm system commissioning procedure after installation.
