DST Sampling Tubes for Duct Smoke Detectors

The DST family of sampling tubes are pieces of steel piping with a series of holes drilled the entire length of the tube and should extend the entire width of the duct.

The sampling tube must be purchased separately. The correct length has to be chosen for width of the duct where it will be installed. The sampling tube length must extend at least 5/8 across the duct width for optimal performance. The sampling tube is always installed with the air inlet holes facing into the air flow.
