Bosch Twinguard Binding - received alarm is missing

Hi,

I have several Bosch Twinguard smoke detectors. This is also available via the existing Bosch binding. I only have the problem that there is no value in the binding that maps the alarm. if the Twinguard triggers an alarm, I would like to receive it in OpenHAB. how does it work, is this function missing in the binding?

Many thanks!
