What's the monthly fee (approximate)?

Do you need line of site through a window, or do you need to mount an
external antenna on the roof?    How many feet of coax can that cable run to
the base unit?

Well that's nasty.    Why would they limit it so much?     Is there any way
to map all of the extra zones into one of those four zones so you at least
get a generic zone triggering?   You could get the detail from the primary
