New project necessitating a "plenum" rating

[turk182]

I have been assigned a new project for an electrical device for use in a &quot;ceiling tile / suspended ceiling&quot; setting. It is a low voltage device (only 9V DC running into the ceiling).<br>
<br>
Does anyone know what UL or NFPA plenum ratings I will need on my enclosure, cable, and connectors.<br>
<br>
Plenum rated cat-5 cable is available, but I am wondering about the connection at the enclosure, which is in an air-handling space.<br>
<br>
Any help / insight would be greatly appreciated.<br>

I belive the boxes and connector must be plenum rated.
