Foreign equipment is not managed by FOXMAN-UN, but can be displayed as NES with foreign object symbols on the maps.

Using a special alarm collecting unit ALCAR in a FOX51x NE, alarms and also commands can be associated with foreign objects. These alarms will then not be treated as belonging to the NE where the unit is located, but are shown as part of the relevant FO. The alarms can be customized to be visible on FO.
