The Edwards 4-LCD is the main colour touchscreen LCD display for the Edwards EST4 life safety control platform. It mounts on the inner door frame of EST4 control panels, where the inner door also acts as a deadfront separating users from the field wiring behind it.
The display always shows the last highest-priority event, sorts events into easy-to-access queues by type, and shows a count of active events with a visual flag for anything not yet viewed or acknowledged. Messages can be shown in any two of the EST4-supported languages, switched with a language button on screen. This is the display module on its own; Edwards also offers it pre-cabled as the 4-LCDANN (annunciator mounting) and 4-LCDLE (cabinet and large annunciator mounting).
