HELP Gecko G320/G340 FAULT/RESET MANAGER circuit

I am planning on using the Gecko G320/G340 FAULT/RESET MANAGER circuit, on my
system that I am building, and have the following questions.

1. Can I still use a seperate SPDT Center off switch, with this circuit for a
manual Stop or Reset?

2. Does anyone have a Printed Circuit designed for this circuit, so I don't
have to reinvent the wheel? If so and you would like to share, please send
me a copy direct if possible. Or better yet load it in the list files
section, with the schematic if possible.

3. Is the ERR/RES terminal subject to noise, if I hook up a EStop line, from
a remote location? (18-30 inches).

Any help or answers on any of the above questions would be greatly
appreciated.
Thanks,
bill
