Hochiki 0400-01570 is the part number for the 10 ft air intake sampling tube (model STS-10.0) for the Hochiki DH-100-A analog duct smoke detector. The detector samples duct air through two tubes that protrude into the duct, and the intake tube must be ordered separately once the duct width is known. Installers select the 10 ft length for wide ducts and cut it down to fit.
