VL-Service 09 refers to the customized integration of the DMT-10 digital audio module into a VARIO-LINE compact control unit, featuring automated “All CALL” activation upon audio playback. When a stored message is triggered, the system automatically switches to “All CALL” mode—broadcasting the announcement across all zones or speaker lines.

This configuration is particularly suited for critical safety applications where immediate, full-area message distribution is essential—such as evacuation alerts or emergency instructions. The DMT-10 reliably plays preloaded audio files and simultaneously controls the zone routing, eliminating the need for manual intervention.

Example Use Case:

Press button to start announcement → DMT-10 begins playback → System automatically switches to “All CALL” → Message is broadcast to all areas.
