Fibaro FGSD-002 reports system alert

[Ernstl]

Hi there,

i own 5 Fibaro Smoke Sensor FGSD-002 an connect them to my Z-Wave System running on domoticz.
Now i got some Problems.
First all was ok with them, but now one by one they report System Alert in domoticz. There are no lights or acoustic signals on the hardware, so i don't understand what the alert is worth.
The only thing i found is the command class for this. But i´m not sure if its right.
I think it means malfunction, found it in the manual of z-way. Correct me if i´m wrong.

Now i want to delete the alerts.
I tried to reset bei software, and a Hardware reset with exclusion and new inclusion. Nothing worked. The only thing i found was a timeout notification in the protocoI.
don't belive that all have Malefunction, but what can i do?
any suggestions?

I have one FGSD002 that is showing the a similar behaviour but it send Alarm Level: Secure. Still investigating so any help would be appreciated.
