Nearing the end

While it has taken more than 15 minutes, I inherited a hot mess  installed by some "trained professional in the past:

Issues so far: 

One busted window sensor.

Two finicky motion sensors (Honeywell DT-7235T) reporting no motion but powered up.

and scaring the crap out of everyone when I first disconnected the power before disconnecting the battery and started removing things, The old system went into a tamper alarm.

And finally not ordering enough modules to cover my updated zones after separating all the exterior doors off. (a second master is on the way) Thanks guys.
