In which applications are CMR communication riser cables permitted to be used?

CMR communication riser cables are specifically designed for use in vertical spaces between floors in a building, known as risers. They are rated for this purpose due to their fire-resistant properties, which help prevent the spread of fire along vertical spaces. The rating ensures that these cables can be used safely in both in-wall setups and riser applications, providing flexibility for installation in various environments within a building.

These riser-rated cables are suitable for use in-wall applications because they meet the necessary fire safety standards for residential and commercial structures. They can help maintain fire safety regulations while delivering reliable communication capabilities.

While riser cables are primarily intended for the vertical spaces (riser applications), their approval for in-wall applications further emphasizes their versatility, allowing them to be utilized wherever there is a need for reliable communication wiring within walls or vertical spaces. This makes them practical for a wide range of projects and installations, ensuring both performance and safety in the electrical infrastructure of buildings.
