Kidde - Edwards SD-T120 Air Sampling Tube 120

Product Description

The KIDDE - EDWARDS SD-T120 is an air sampling tube designed for use with duct and beam smoke detection systems. This component draws air from a monitored space or duct and delivers it to the sensing chamber of a compatible detector, allowing the system to continuously sample for smoke or combustion byproducts. The SD-T120 is sold individually and is a replacement or supplemental accessory for existing detection installations. It is typically installed by licensed fire alarm technicians or qualified HVAC professionals working on life-safety systems.

The SD-T120 is suited for commercial and industrial applications where duct or beam-type smoke detectors are installed in air handling units, return air plenums, or open-area beam detection layouts. Air sampling tubes are a critical interface component in these systems, ensuring that air is consistently routed to the detector sensing element. This tube is appropriate for new installations and service replacements where the original sampling tube has been damaged or lost.
