The Edwards SD-TRM Remote Test Station is an accessory designed for compatible Edwards SuperDuct duct smoke detectors. It provides a convenient remote location for testing and monitoring a duct detector when the detector itself is installed on HVAC ductwork, above a ceiling, or in another difficult-to-access location.
Unlike the SD-TRK keyed remote test station, the SD-TRM uses a magnetic test switch, allowing technicians to initiate a detector test with the appropriate test magnet.
Product Functions
