I have to replace the alarm panel (keypad) in my house with a more up to date one. The old one did not have a transformer and was powered by a separate PSU supply providing the 12v supply. The new panel has a built in transformer that should be connected to the mains.
Is it possible that I can bypass the built in transformer and simply use the existing PSU supply? If so, can I connect the PSU +/- to the AC connections on the board?
