Applications
- Use in security system wiring where a plenum-rated cable is required for indoor routing.
- Support intercom/PA installations that need multi-conductor cabling for signal distribution.
- Connect audio/speaker runs in building spaces where plenum compliance is specified.
- Fit power-limited controls for indoor control circuits that call for a shielded construction.
- Handle noisy environment installations where shielding helps manage interference in the cable run.
