Edwards Signaling SD-TRK SuperDuct Series Remote Test Station for 2-wire detectors, keyed

Bring reliable, code-friendly duct smoke detector testing to confined spaces with the Edwards Signaling SD-TRK SuperDuct keyed remote test station. Purpose-built for 2-wire duct smoke detectors, this remote test/reset station lets technicians exercise and verify detector operation from an accessible wall or duct location — eliminating the need to access hard-to-reach HVAC plenums and speeding routine maintenance. The low-profile design is less than 2" deep and measures 5.5" x 4.3", making it ideal for tight mechanical rooms and retrofit projects.

The SD-TRK features a PCB-mounted photoelectric sensor with patented environmental compensation to reduce false alarms from normal airflow or particulate conditions. A keyed reset prevents unauthorized resets and tampering, improving overall site security and compliance for life-safety and fire monitoring systems. Rated for 125V DC input and engineered for SuperDuct installations, this remote test station integrates smoothly into building fire detection, security, and monitoring strategies.
