Edwards Signaling DSD-4W-RJ45 is a photoelectric duct smoke detector subassembly designed for installation in HVAC ductwork. It uses a four-wire RJ45 interface to connect with Edwards fire alarm systems, providing a duct-mounted smoke sensing capability. This subassembly leverages photoelectric sensing to detect smoke particles in the airstream, enabling early warning when paired with the appropriate Edwards components. It is configured for use in commercial or industrial air handling applications where duct smoke detection is required.
