bOS Bacnet ID

Hi all!

At an installation, the fire system was changed to a Siemens Cerberus.
Their system communicates in BACnet but needs to know the BACnet ID of the system that queries it.

How do I set the ComfortClick (physical JigsawPro machine) to have the Bacnet ID that they associated with me?
I can't find anything about it in the settings.

Thanks
