Hello, I am interested in purchasing a konnected board. I have a quite old ADT system. The only problem is the closet that the panel is all connected into has no power plugs. Though the old panel is likely getting direct connected power somehow. Is there any way to utilize these existing power cables to power the board? I'm not sure where the power cables are but I do see markings on the diagram called "AC in via 16 VAC". I have a few photos of the panel I will attach. Thanks!
