Here just sort of picky relating to what I connect to my OP2 panel and paranoid about damaging it or even taking a chance on doing that such that I went to the combo Elk doorbell board and debounce circuit and autonomous PS for the stuff and only used the 24VAC doorbell power supply for the LED doorbell. Overkill I guess.
