I guess someone would probably at the same time remove the tamper wires and
set them in whatever state (closed or opened) that would be needed to fool
the panel?   There would be a brief tamper alarm, but it would go away and
the alarm center might not act on it.

What would be a lot more useful to me would be some device that would send
out e-mail notifications to a list of people based on circuits being seen as
open or closed (user settable).   That way even a single tamper alarm is
going to be seen by someone inside the company, almost for sure.    Does
such a thing exist, or I guess you could just use a separate alarm panel for
this purpose?

Does having the tamper circuit in place improve this situation?
