Description

The Edwards SD-TRK4 is a commercial keyed remote test/reset station designed for use with Edwards SuperDuct™ 4-wire duct smoke detectors. It provides a convenient remote location for testing, resetting, and monitoring compatible duct smoke detector systems without requiring direct access to the detector installed in HVAC ductwork.

The station features a keyed momentary test/reset switch and three status LEDs for Power (green), Alarm (red), and Trouble/Dirty Detector (yellow) indication. It simplifies routine inspection, maintenance, and NFPA-required testing while improving accessibility for service personnel. This product is intended exclusively for commercial fire alarm installations.
