Everything you've said up to this point is pretty much what I
would have done as well.  The detector covering hallway 126
(below) can work if it's a short enough range so as not to "see"
the windows and if there's no chance of reflected sunlight,
headlights, etc., hitting the detector face.

As an alternative to the detector near 107 which protects hallway
126, have you considered installing a detector in the NE corner
of room 105.  That would cover room 105 and almost half of
corridor 126 (assuming that the back of the L-shaped counter in
room 105 isn't very high.  If the partition is too high, you
might consider placing a narrow angle detector on the wall above
the window near the SE corner of room 105.
