Choose the conductor gauge by matching the cable to the system’s current requirements and the installation distance, using a larger conductor, such as 16 or 18 AWG, when the application calls for more capacity or longer runs, and smaller conductors, such as 22 AWG, for compatible low-current circuits. Choose the number of conductors based on the devices and signals being connected, such as two conductors for a simple circuit, four or six for systems with multiple connections, or shielded cable when the equipment documentation calls for added signal protection.

Shielded riser rated cables include a conductive layer that helps reduce electromagnetic interference in environments with electrical noise. Unshielded riser rated cables do not have that layer and can offer a simpler installation for many security, alarm, intercom, audio, and control applications where interference is less of a concern.

Yes, riser-rated cables can support security, fire alarm, audio, and data installations when the cable’s conductor count, gauge, shielding, and application rating match the system requirements. Use designated fire alarm cable for fire alarm circuits, Category-rated cable for data networks, and compatible security or audio cable for alarm, intercom, control, and sound applications.

When installing riser rated cables, confirm that the cable’s rating, such as CL3R, CMR, or FPLR, matches the building code, pathway, and application, and select the appropriate conductor count, gauge, shielding, and signal type for the system. Plan routes through vertical spaces, keep power and signal cabling separated as required, follow fire-stopping practices, and use clear length markings and tangle-resistant packaging to support a cleaner installation.
