Thx Bryan 5Cradles 02-10-07, 10:47 PM If monoprice doesn't have them then maybe they don't make a plenum rated HDMI cable. James Lenexpo 12-21-07, 03:29 PM Atlona Technologies is the first and only company to release plenum HDMI and DVI cables. For schools, hospitals, and government buildings, the plenum space above drop ceiling and under raised floors is the optimal place for routing communication and A/V cables. In order to use these plenum spaces, installers need to use special cables designed to prevent the spread of fire. In the event of fire, its outer material is more resistant to flames and, when burning, produces less smoke than ordinary cabling. For installers wanting to route digital video through plenum spaces, the only option has been to use expensive CAT5 extenders, and Plenum CAT5 cable. According to Article 800 of the National Electrical Code (NEC), plenum cables must comply with the specifications for flammability and smoke density outlined in Underwriters Laboratories (UL) and National Fire Protection Association (NFPA) testing methods. Until now, the only cables made to comply with these standards were Twisted-pair and coaxial. Atlona Technologies is the first to offer HDMI and DVI cables that meet these requirements, as well as the HDMI 1.3 certification requirements. These cables will be available by the end of Q1 2008, in lengths ranging from 15 to 50 feet. kiwishred 12-21-07, 06:38 PM the only option has been to use expensive CAT5 extenders, and Plenum CAT5 cable.Is it the only option ? I am wondering if the some sort of conduit could be used, with ordinary cable within the conduit ? Brent Lenexpo 12-21-07, 06:53 PM Unfortunately no, running a conduit through a Plenum space is not going to comply with the NFPA 90A standard. Sandpiper 12-22-07, 07:45 AM Unfortunately no, running a conduit through a Plenum space is not going to comply with the NFPA 90A standard. Sorry, I'm not familiar with the NFPA 90A standard. But If I understand what you are saying, NFPA 90A says it is prohibited to run conduit in a plenum space but it is OK to run bare plenum rated cable in this same space? Is this correct? hoye0017 12-23-07, 05:37 PM Unfortunately no, running a conduit through a Plenum space is not going to comply with the NFPA 90A standard. Can you please quote an article that states this? I work in commercial buildings regularly that use MC to route high and low voltage cables in what would be considered plenum spaces. Also, bgarcia, mind if I ask why you need plenum rated specifically? Plenum rated is not necessary very often. Sandpiper 12-24-07, 08:10 AM Can you please quote an article that states this?

If his statement were true, then the NFPA 90A standard would be in direct conflict with another NFPA standard....NFPA 70, the National Electric Code. I believe it would be a very rare case where the NFPA documents would be conflicting. tiquer 05-21-08, 04:17 PM I thought the only way to avoid buying plenum cable was to run it through conduit. If that is not true, please advise!!!! |
