Reply to "Wiring an Atlas 6924 N-D Board w/ #57 Switch Control"

Stewart - Just starting to wire my layout and am practicing on a couple of 072 atlas switches joined to form a simple (and short) siding. I have the 6924 non-derail board and a dwarf signal kit 6931 which comes with a circuit board. After looking at the Atlas wiring instructions for this combination, it appears I do not need the board supplied with the 6931 kit because I should be able to control the dwarf signal directly from the 6924 - J3. Can you confirm this?

A few more questions - The instruction say the 6924 will work for 2 switches, but I don't think I see how to wire a second switch and last, if I am reading the diagram right, I must connect 2 wires to the isolated rails right near the switch convergence, which seems like last second switching when the derail detection occurs. Is there a way to move detection out further with an isolated rail prior to actually getting on the switch track?

Thanks,

Mike Monjure
