The EST4 offers enhanced IP-based communication compared to the EST3's traditional networking.

Note: Edwards does not sell SDU directly to end users; only to authorized distributors and certified system integrators.

Programming an EST3 system with the SDU typically follows a structured sequence:

| Module | Function | |--------|----------| | | Main programming interface: define hardware, zones, messages, C&E rules | | Panel Database Creator | Prepares a blank database for a specific panel firmware version | | Graphics Manager | Links floor plans and custom graphics to points/events (used with EST3 Vision) | | Network Manager | Defines peer-to-peer messaging between nodes, including global rules | | Debugger / Simulator | Emulates panel behavior offline to test C&E logic before downloading | | Firmware Loader | Updates bootloader, application code, and voice firmware for an AMG-1 or PMC | | Event Logger Viewer | Parses and filters panel history logs downloaded via serial or TCP/IP |

Each EST3 module has three distinct software components managed by the 3-SDU:

Click the "Verify" button (Checkmark icon). The SDU checks for:

A granular interface to set parameters for every component, such as detector sensitivity levels, time delays, and device labels (up to 40 characters). Mapping & Diagnostics:

The SDU features built-in diagnostic and reporting utilities. It can generate comprehensive system reports, including loop maps, device parameters, system response matrices, and battery calculations. These reports are invaluable for submittal packages and annual NFPA testing certification. 6. Best Practices for EST3 SDU Users
