Issue
The DALI Emergency Status Light object contains several status-related properties that are represented as an Integer value. Each Integer value corresponds to one or more status flags reported by the DALI device.
The purpose of this article is to provide a clear mapping between the Integer values and their corresponding flags for each DALI Emergency Status property.

Resolution
The DALI Emergency Status Light object reports several status-related properties as Integer values. Each value represents one or more active status flags using a bitmask calculation.
How to interpret a status value
- Identify the property being evaluated (for example, Emergency Mode or Emergency Status).
- Locate the corresponding flag table below.
- Compare the reported Integer value against the available flag values.
- Determine which flag values add up to the reported Integer value.
- The resulting flags represent the current state reported by the DALI emergency device.
Example
A device reports an Emergency Mode value of 10.
| Value | Flag |
|---|---|
| 2 | Normal Mode |
| 8 | Extended Emergency Mode |
Because:
10 = 8 + 2
the following flags are active:
- Normal Mode
- Extended Emergency Mode
Multiple flags can be active simultaneously, resulting in a combined Integer value.

| 128 | Duration test failed |
Emergency Status
| Value | Flag |
|---|---|
| 1 | Inhibit Mode |
| 2 | Function test done and result valid |
| 4 | Duration test done and result valid |
| 8 | Battery fully charged |
| 16 | Function test request pending |
| 32 | Duration test request pending |
| 64 | Identification active |
| 128 | Physically selected |
Validation
After decoding the reported value, compare the active flags against the current device condition, including:
- Emergency lighting operating mode
- Test status
- Battery status
- Reported device failures or alarms
Confirm that the decoded flags accurately reflect the observed state of the DALI emergency device before proceeding with further troubleshooting.
Important Notes
- Each status flag is represented by a unique bit value.
- Multiple active flags are combined into a single Integer value.
- A higher value does not necessarily indicate a more severe condition.
- Always decode the Integer value into its component flags to understand the actual device status being reported.
