Edwards Signaling 60-Inch Sampling Tube

Optimize duct smoke monitoring with the Edwards Signaling 60-Inch Sampling Tube (SD-T60), engineered to deliver reliable, low-profile detection where space is limited. This detector accessory provides stable, drift-resistant photoelectric sensing mounted on a PCB with onboard intelligence, minimizing false alarms and reducing maintenance for building security and fire monitoring programs. At 60 inches long and under 2 inches deep (1.9" height), the sampling tube installs cleanly in tight HVAC plenums and duct runs while supporting high air velocities up to 4000 ft/min—ideal for commercial and industrial ventilation systems. Designed to work with standard Kidde Intelligent detectors and the Four-wire Duct Smoke Detector SD-4WJ, the SD-T60 integrates into existing fire detection, surveillance, and building automation systems with minimal rework. Rely on Edwards Signaling quality to enhance your smoke detection strategy across data centers, retail, healthcare and other critical facilities. Add the SD-T60 sampling tube to your duct detection layout to improve response times and maintain regulatory compliance—contact us to specify or order for your next installation.
