Know before you buy
This rating indicates that the cable jacket is designed to be fire-resistant and produce low smoke, making it safe for use in plenum spaces like drop ceilings or raised floors where air circulation occurs. It meets strict fire safety codes for commercial and residential buildings.
Yes, the jacket is UV- and rain-resistant, which allows for outdoor use. However, it is not rated for direct burial or constant water immersion, so it should be run through conduit if installed underground or in areas prone to standing water.
The shielding helps protect your signal from electromagnetic interference (EMI) caused by nearby power lines or electronic devices. This ensures a more stable and reliable connection for sensitive security and sound equipment.
This cable features stranded bare copper conductors. Stranded wire is more flexible than solid wire, making it easier to route through tight spaces or around corners during installation.
No, this is a low-voltage cable designed specifically for security, alarm, control, and sound systems. It should not be used for high-voltage electrical wiring.
