Hello everyone - I seemed to have bitten off more than I can chew. A couple of years ago we had a Galaxy G2-20 installed, I recently decided to change that unit out for a Galaxy Dimension with an separate Ethernet module. The mistake possibly was thinking I could do it myself.
Below is the steps I've taken so far:
*** Removal of the G2-20 ***
Disconnected power & battery
Disconnected battery from the outside bell
Wrote down and took photos of the G2-20 wiring
Removed wiring
Removed unit from the wall
*** Installation of new Dimension unit ***
Fitted unit to the wall
Connected the MK7 to the RS485 line 2
Power up and all works OK
Now I want to start connecting up the inputs (PIR's & 1 door sensor), the outputs (internal bell & external bell). However, the 2 issues I'm having are, firstly the G2-20 had a negative on the AUX power, yet I cant find any negative on the Dimension. Secondly, I cant work out how to connect the internal and external bells. I have included the photo I took of the G2-20 before removal and the new Dimension installed. If anyone can help I would really appreciated it?
Many thanks
Tony
