Some keypads have a zone input on them.  If the installer
pre-wired the door contact at the same height as the keypad he
may have intended using that feature.

That transformer *might* be for a doorbell or some other
non-alarm function.  The cable protruding below the duplex outlet
was probably intended for the alarm transformer.  Although it's
not really the proper cable, I've seen some installations where
the tech bundled two pairs of CAT5 wire to one terminal and two
to the other for the transformer.  If you parallel four 24-gauge
wires together, the effect is ~18-gauge.

The alarm transformer.

In the USA they would not be a code violation since they're low
voltage.  You'll find the same thing in almost every home -- a
doorbell transformer.  It's possible someone installed that
doorbell transformer instead of the usual alarm transformer but
I'm guessing that's not it.
