Re: Vista 20 and IR motion problem

[Nomen Nescio <nobody@xxxxxxxxx>]

You are giving two different ways to do this, one of which disarms the
system automatically, and one of which only shunts the downstairs IR zones.
The zone shunting version I think I'd need to see drawn out, I don't
entirely follow that from your description.  However, I see one big problem
with the automatic disarming version, if I understand you correctly:

Burglar trips downstairs motion.  Alarm sounds.  Burglar heads upstairs,
crossing the arm/disarm motion along the way, and disarms the system.
Alarm stops.  Maybe even sends in a cancel signal.

And if I understand this correctly, under normal conditions the system does
not rearm itself when the user heads back upstairs.  That would be a
drawback for a sleepy homeowner who heads downstairs at night, and remains
unprotected from then on.
