Edwards SD-TRM Remote Test Station

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

• Provides remote testing of compatible duct smoke detectors
• Uses magnetic test activation
• Provides remote alarm indication
• Provides remote trouble indication
• Allows detector status to be viewed from an accessible location
• Designed for Edwards SuperDuct systems
• Supports compatible intelligent duct smoke detectors
• Provides a momentary test switch
• Uses LED status indicators
• Installs remotely from the duct detector
• Designed for single-gang installation

LED Status Indication

The SD-TRM incorporates LED indication to provide remote information about the connected duct detector.

The remote station provides visual indication associated with:

• Alarm condition
• Trouble condition
• Detector testing

SD-TRM vs. SD-TRK

Edwards provides two common remote test-station configurations:

SD-TRM: Magnetic remote test station

SD-TRK: Keyed remote test station

Installation Information

The SD-TRM is intended for installation at an accessible location where maintenance personnel can conveniently perform duct detector testing and observe status indication.

Typical installation includes:

• Selecting an accessible remote location
• Installing the appropriate electrical box
• Routing wiring from the duct detector
• Securing the SD-TRM
• Restoring detector operation
• Applying the test magnet
• Confirming detector alarm response
• Confirming remote LED indication
• Verifying alarm reporting at the fire alarm control panel

The exact terminal connections and allowable wiring distance should follow the documentation for the compatible SuperDuct detector.
