When this setting is enabled, the Casambi CBU-DCS gateway periodically checks the DALI bus for connected DT1 emergency luminaires. The scan interval determines how frequently this check occurs. During each scan, the gateway:
- Detects any newly connected or removed DT1 devices
- Updates the status and availability of existing emergency luminaires
- Ensures that the Casambi network has an up-to-date view of the emergency lighting infrastructure
This is particularly important in systems where emergency lighting compliance and monitoring are required. A shorter scan interval ensures that changes in the emergency lighting setup, such as a device failure or replacement, are detected quickly. A longer interval reduces bus traffic and is more suitable for stable, long-term installations.
