Information About 3-DSDC
The 3-DSDC is an EST3 local rail module that provides two independent Signature data circuits for high-capacity addressable fire alarm installations. Each circuit supports up to 125 Signature detectors and 125 Signature module addresses, allowing one 3-DSDC to manage as many as 250 detectors and 250 modules across both loops. The controller uses Edwards Signature digital communication technology with electronic addressing, automatic device mapping, nonvolatile mapping storage, detector sensitivity management, and diagnostic reporting for compatible field devices. Class A or Class B circuit configurations and EST3 local-rail integration allow the module to serve as a scalable detection and control interface in commercial, institutional, industrial, and campus fire alarm networks.
Key Features:
- Dual Signature Loops: Provides two independent Signature signaling line circuits from a single EST3 local rail module.
- High Device Capacity: Each loop supports up to 125 Signature detectors and 125 Signature module addresses.
- 500-Address Combined Capacity: Supports as many as 250 detectors plus 250 module addresses across both circuits.
- Signature Digital Protocol: Communicates digitally with compatible Edwards Signature Series detectors and modules.
- Electronic Addressing: Compatible Signature devices are electronically addressed without conventional mechanical address switches.
- Automatic Device Mapping: Creates and maintains a map of connected field devices to simplify commissioning and troubleshooting.
- Device Location Monitoring: Detects changes involving missing, added, or relocated Signature devices.
- Nonvolatile Mapping Storage: Retains circuit mapping information in nonvolatile memory for reliable system operation.
- Detector Sensitivity Management: Supports programmable sensitivity functions and maintenance reporting for compatible Signature detectors.
- Class A or Class B Wiring: Supports common addressable signaling circuit configurations for flexible system design.
- Local Rail Integration: Installs directly into the EST3 local rail architecture for panel power and system communication.
- Removable Field Terminals: Provides service-friendly terminal connections for Signature circuit field wiring.
The 3-DSDC delivers the reliability and precision required for high-capacity addressable detection, supervision, and Signature device control in Edwards EST3 fire alarm systems.
