System Sensor Metal Sampling Tube Duct Widths 0.3 to 0.6m (Not Compatible with DH400E and DH400ACDC-E)

The DST1.5 is a Conventional sampling tube designed for duct widths ranging from 0.3m to 0.6m, supplied as an accessory under order code FG-01-006 for use with both Conventional and Intelligent Duct Smoke Detectors. It is constructed from metal and is UL listed, helping to ensure compliance with safety standards for air sampling applications in HVAC systems.

This sampling tube is engineered to extend across the duct to facilitate representative air sampling, supporting effective detection when paired with compatible duct detector housings such as the DNR/DNRW intelligent housings or the D2 2-wire conventional duct detector. Physical wiring and installation details are not included in the published product data and must be referenced from the official installation manual. The tube’s metal construction provides durability in typical duct environments, and its UL listing confirms adherence to recognised safety benchmarks. It is intended solely as a sampling component and does not include detection electronics, which must be sourced separately as part of a complete duct detection system. Proper installation requires adherence to the manufacturer’s guidelines to ensure optimal performance and sampling accuracy across the specified duct size range.
