Hi,
I was wondering if someone could explain this weird setup for a phone
jack in one of my bedrooms. The wall plate has what looks like quad
wire coming out from behind it (pinched between the drywall and the
edge of the plate) and this cable in turn goes to a wall wart plugged
into an outlet with two screw terminals on the underside. One screw has
the red wire, the other the green wire. Is this some sort of alarm
circuit? My house was built in 1976, FWIW.

Alarm maybe, but doubtful. More likely, the power supply for an early
version of a trim line or princess phone.
The first versions of those phones wouldn't operate on phone line
voltage. They needed their own separate power supply to light the
buttons, etc.
Take care,
Rich
God bless the USA

This would make a lot of sense, since this bedroom is the master
bedroom...thanks for your prompt response! :)

Yep - I completely forgot that the Trimline I have in my posession is a
1982 vintage. It had the green LED lighting that ran off line current.
Problem is I modified this phone to use it with Skype. Normal plan calls
for one 9V battery but I had to parallel two 9V units for the extra
current.

If you don't have the phone, it's a good idea to disconnect the wall wart..
there was a certain model that had a tendancy to overheat, and could
cause fires.
I'm guessing that it's grey, made by western electric, and about
1.5"w X 2.5"h X 1.5"d (from memory.) rectangular, with straight sides,
and rounded corners and edges. I seem to recall that the guts were potted.
