Reading out the alarm memory
The last 10 DWA alarms are saved in the FZD control unit alarm memory. The alarm memory is read out together with the fault memory. Each time an antitheft alarm is triggered the following supplementary information is also stored:
- Alarm trigger signal with history
- Date and time display
- Ambient temperature
NOTE:
The charge status of the internal batteries in the emergency power siren can be accessed using the diagnosis tool.
