Yes.  I thought about an expander and doing it the shortcut way , or
running new wire for the tamper zone and put them all together on a 24
hour (almost useless).  Or do it right and run more wire AND add the
expander.  <sigh>  Me and my big mouth.  We never discussed this
feature - I added the tampers for him to see if a motion was bad when
he armed.  But then I had to open my big mouth and tell him about
scheduling, which is programmed to auto-arm, which led to this cluster
fuck.  In retrospect I made the error.  I should have anticipated his
needs and offered it from the beginning.  Shit.

Ahh,  I didn't recognize (recognise for Doug) the acronym.  Ademco
does not support it-- but it does give me an idea.  I could swap the
board for a Vista-20 and do some zone doubling nappy-headed-ho
rigging.
