I need to add a second chime in a house. The existing unit is a standard NuTone kit with two pushbuttons (18/2 from each pushbutton, and 18/2 from xfmr to chime unit).
I haven't done this before, but thinking about it and researching it lets me believe I need to upgrade the xfmr (in mechanical room) and fish a wire (18/3) from existing chime unit to additional chime unit to tie the three terminals (Back door, front door, xfmr) from the first chime unit to the second.
Am I thinking about this correctly? Anything else I need to consider doing?
Thanks,
Sky
