FCDC-3 - Backwards compatibility

The FCDC-3 is fully compatible with FCDC-1, FCDC-2 (including TFIX stations and https://exigo.zenitel.com/wiki/Category:Ex_Access_Panels Exigo Ex Access Panels) after these devices have been upgraded to software version 4.1.3.13 or newer.

• If these devices are running version 4.1.3.12 or older, there will be no compatibility. There will be no connection between the Flowire units.

If you mix software version 4.1.2.12 (or older) and version 4.1.2.13 (or newer) on the same Flowire network, there will be limited compatibility. You can do software upgrade, but regular operations will not work.

Update of EX-stations must be done using a FCDC2
