If I have an existing single-room Grafik Eye 3106 installation and want to integrate it into a new Homeworks 4/8 series whole-building installation by connecting it to a dedicated Grafik Eye/WPM communication link, what is going to happen with the existing GRX wallstations? Can they
1) remain connected to the Grafik Eye
2) have to be connected to a dedicated keypad link or
3) are they redundant in a Homeworks system?
