actually, you are ok running non plenum cable above drop in ceilings if 
both the send and return for the HVAC is in a tube thingie.  only if the 
air passes through the area above the drop in ceiling should you use 
plenum cable.

i have yet to see any drop in ceilings in a residence, though.

Regards,
