16/4 Shielded Riser (FPLR) Fire Alarm Cable
Engineered for demanding installations in electrically noisy environments without the premium cost of plenum rating, this 16/4 shielded FPLR riser-rated cable features four heavy-duty solid bare copper conductors with aluminum mylar shielding and a CMR-rated PVC jacket. The robust 16 AWG conductors deliver lower resistance and higher current capacity than 18 AWG alternatives, while the integrated 24 AWG drain wire and comprehensive shielding provide superior protection against electromagnetic interference (EMI) and radio frequency interference (RFI)—ensuring reliable signal integrity for longer cable runs in challenging electrical environments at economical riser pricing.
Proudly made in the USA and ETL-listed, this heavy-gauge shielded riser cable combines the electrical performance of premium cables with interference protection, all at a more cost-effective price point than shielded plenum for vertical runs and non-plenum installations. Sequential footage markings simplify installation tracking and reduce labor costs.

Why Choose 16/4 Shielded Riser Cable?
Heavy-gauge shielded riser fire alarm cable offers premium performance at economical pricing:
- Superior electrical performance - 16 AWG offers lower resistance than 18 AWG for longer cable runs
- EMI/RFI protection at riser pricing - significant cost savings vs shielded plenum
- Higher current capacity for power-demanding devices in noisy environments
- Signal integrity in electrically noisy vertical runs and standard installations
- Reduced voltage drop on extended cable runs near interference sources
- Professional-grade solution combining heavy-gauge performance with shielding
When to use Shielded FPLR vs Shielded FPLP:
- Use Shielded FPLR (Riser): Long vertical runs near motors/equipment, electrically noisy standard rooms
- Use Shielded FPLP (Plenum): Air handling spaces with interference sources, noisy plenums
16 AWG vs 18 AWG Shielded:
- Choose 16 AWG: Longer cable runs, higher current requirements, demanding installations in noisy areas
- Choose 18 AWG: Standard runs with moderate electrical performance needs
Ideal for commercial buildings, industrial facilities, manufacturing plants, and any demanding 4-conductor installation where both heavy-gauge electrical performance and EMI protection are required in vertical runs or non-plenum spaces—providing professional-grade interference protection with superior current capacity at economical riser pricing.
