If on the ground and engine stopped you will have several warnings obviously.
No doubt you are aware that in the B3 you are obliged to have 2 functioning headsets ( Pilot and Co-Pilot) and ICS as per RFM Limitations.
The Pilot ISO is just doing as it should - isolate the ICS.
I would guess that your warning unit and/or sensor that talks to the warning unit is duff.
You are right, engine at flight idle and ready to depart. I did not test it with all the bells and whistles because you probably would not recognise it anyway. I did unplug the headsets to see whether it makes any difference.
Some people (i.e. older) might not even hear it as it is very high frequent tone and not very loud. It is clearly linked to anything which engages with the HORN switch and the warning unit is a good start...
Thank you for the hint. I will relay it ... and get back as soon as I know what it was.
