Help identifuing a wire

["JOhn" <barnesj@xxxxxxx>]

Ive seen my share of poorly done prewires, but this one really has me
scratching my head. The PIR's are wired at 6ft. The doors are drilled
through  the casing, not the jamb, so a standard flush mount 3/8 contact
isnt an option.  The keypads are wired to the same hieght as the swiches
(not above)


all that aside....
This is a pic of the inside of the mstr bdr walk-in closet, above the door.

The cat5 dangling out of the wall runs to the alarm panel location.  Any
idea what device it may have been intended for?

... And whats the 120v duplex outlet for?  In the old days they used to put
an outlet centred, above a high traffic door for a clock.

Also, wondering if the exposed terminals on the t-stat transformer are a
violation of code. (this is B.C. Canada)
