Marc,

There are some photo beams that come without a
conventional housing.  Basically, you get an emitter
and a sensor, each attached to a wire.  They're very
small and can be worked into a cabinet, door frame
or whatever during construction.  Unfortunately, from
what you've shared about your home, they would be
a royal pain to install there.  Also, they are a bit on
the pricey side.  The make and model number escapes
me at the moment but if you're interested in knowing,
give me a shout during the work and I'll find ot.

BTW, from the image of the Pyronix sensor, I doubt
it would score high on the WAF scale.  It's pretty
large and kind of commercial looking.
