Edwards Signaling SD-2W two-wire duct smoke detector

Technical Specification

Features:

Make: Edwards Signaling
Model code: SD-2W
Type: Smoke
Style: Rate of rise
Mode: Conventional

Additional info:

Edwards Signaling SD-2W is a two-wire duct smoke detector that use differential sensing to prevent gradual environmental changes from triggering false alarms. A rapid change in environmental conditions, such as smoke from a fire, causes the detector to automatically signal an alarm condition but dust and debris accumulated over time does not change alarm sensitivity.
