Product Description P/N: SD-2W
Description
The Edwards SD-2W is a two-wire photoelectric duct smoke detector designed to monitor air-handling ducts for smoke conditions. Its differential sensing technology helps distinguish rapid smoke-related environmental changes from gradual dust accumulation, while its modular construction supports installation and maintenance in confined duct spaces.

Information About SD-2W
The SD-2W is part of the Edwards EST SuperDuct detector family and uses a two-wire configuration for fire alarm system integration. Its removable dust filter and conformally coated circuit board help protect internal components from contaminants encountered in duct environments. The detector can be serviced by separating the assembly and reassembling it without complex disassembly procedures. A remote test station can also be used to check the detector for contamination without requiring direct physical access to the detector.
Key Features:
- Photoelectric Detection: Uses optical sensing to identify smoke conditions within air-handling ductwork.
- Two-Wire Design: Provides a two-wire configuration for integration with compatible fire alarm systems.
- Differential Sensing: Helps prevent gradual environmental changes from unnecessarily triggering alarm conditions.
- Contamination Protection: Includes a removable dust filter and conformally coated circuit board to help limit contaminant effects.
- Modular Construction: Allows the detector assembly to be separated for cleaning and maintenance.
- Remote Testing: Supports remote testing for dirt contamination without requiring direct detector access.
- Compact Profile: Provides a slim design suited to the restricted spaces commonly found around duct installations.
- Maintenance Access: Components can be removed and reassembled quickly for servicing.
The SD-2W delivers the reliability and precision required for smoke detection and monitoring in HVAC ductwork and air-handling systems.
