Edwards Signaling SD-T78 Air Sampling Tube SF 12/03 The LEDs can be latchedThe Edwards SD T78 78 inch Sampling Tube provides effective airflow sampling for duct smoke detection in HVAC systems with ducts up to 78 inches wide. Designed to work with Edwards duct smoke detectors, this tube draws air evenly across the ducts entire width and directs it into the detectors sensing chamber. This consistent sampling process enables earlier smoke detection and supports NFPA code compliance in larger duct systems.
