Choose red plenum cable marked FPLP or CL3P for plenum spaces, such as areas used for air circulation, and choose riser cable marked FPLR or CL3R for vertical runs between floors or similar pathways, based on local code requirements. For equipment interconnects, red Cat 5e or Cat 6 patch cables provide a flexible option, while the cable type, conductor size, and jacket rating should match the installation environment and system requirements.

Consider 14, 16, or 18 AWG solid bare copper fire alarm cable, with two or four conductors, based on the circuit and connected devices; plenum and riser configurations support different installation spaces. For networking, audio, or video connections, red Cat 5e and Cat 6 patch cables use 24 AWG stranded unshielded twisted pair construction, with length selected to suit the installation.

Red cable jackets provide a quick visual cue that can help installers identify and separate circuits during installation, troubleshooting, and maintenance. When combined with labeling and consistent wiring practices, the red color helps organize fire alarm, networking, and AV cable runs.

For network or AV connections, choose Cat 5e or Cat 6 based on the performance your system supports, and look for RJ45 connectors, stranded unshielded twisted pair construction, and snagless boots for flexible routing and clip protection. Measure the cable path before selecting a length, allowing enough slack for connections while avoiding excess cable, especially in tight equipment spaces.
