When enabled, the Casambi CBU-DCS gateway performs a comprehensive re-synchronization of all connected DT1 emergency luminaires on the DALI bus. This process includes:
- Re-reading all available data from each DT1 device
 - Updating the Casambi system with the latest battery status, lamp condition, test results, and fault reports
 - Ensuring that any changes in device configuration or status are fully reflected in the Casambi network
 
This is particularly useful in scenarios where:
- Emergency luminaires have been replaced or reconfigured
 - A manual override or reset has occurred
 - The system needs to verify compliance with emergency lighting standards
 
The full mode refresh ensures that the Casambi system and any connected DALI monitoring tools have a complete and accurate snapshot of the emergency lighting infrastructure.
