Plenum rated 3.5mm audio cables should be used when installing in the airspace above a suspended ceiling or plenum. These plenum-rated 3.5mm cables are constructed from twisted pair 22AWG wire and precision 3.5mm connectors for a solid and reliable connection. The CMP-rated PVC jacket and FEP inner insulator provide the fire protection required to run these cables within walls and air plenums without the need for conduit. The cable features 22AWG copper conductors covered by aluminum polyester shielding for 100% shield coverage.
