Most of the inputs to the site monitor are ground referenced.  In fact one
of the connections labeled switch input is actually tied to ground.

If you have any sort of reference to ground tied in to the circuit hooked
to the switch input things will likely act oddly.

Above my pay grade. I'm sure Forrest can tell you why. Probably an 
internal ground path thing.

George-
I understand what you're saying, that's not the issue.  Please see attached 
photo, basically I'm asking why switching the wires on the Site Monitor's 
Switch input works one way but not the other.

C=common
NC=normally closed (connected to common when the coil is not energized) 
NO=normally open (opposite of NC)

The SiteMonitor base currently has no internal automatic logic control to 
toggle the on-board relay when the switch contact is closed. I'm guessing that 
was your assumption. That would be a good feature for Forrest to implement.

The "switch" on the base is an open/closed contact monitor (aka input).
Is there continuity or not.

Unless I'm just that dense and cannot understand what you've described here. 
Entirely possible.

Enclosure with a door relay switch.  When the door is open the relay switch 
turns on a light, and trips the site monitor's switch input to send an alert 
that the door is open.

When the circuit is connected as show in the attached PNG the site monitor 
always reads the switch input as 1 or connected regardless of the state of the 
door switch relay.  When we reverse the wires going into the site monitor 
switch input everything works perfectly.  So when the door relay switch's C is 
connected to the right hand side of the switch input and the NO is connected to 
the left it works as expected.

This totally does NOT make sense to me at all :/

I thought perhaps the Site Monitor was bridging the switch inputs and the 
negative rail of the power source internally.  To test that theory I connected 
a different power supply directly to the Site Monitor that was separate from 
the power supply used for the light and network switch and also connected to 
the door relay switch.  But even in this state it performed the exact same.  I 
must be missing something?
