Only the D7412GV4 and D9412GV4 have firmware version 2.x available.
The D7212 type panel has been discontinued after GV4 version 1, therefore the version 2 firmware is not available for the D7212GV4. If the funtionality of firmware version 2 was needed, then upgrading the D7212GV4 to a D7412GV4 or D9412GV4 is recomended.
As an additional option, replacing with a B3512, B4412, B5512 or B6512 may be an excellent option for replacement should the upgrade be desired. Please refer to the B Series documentation on our website at http://us.boschsecurity.com/.
