18/4 Shielded Riser (FPLR) Fire Alarm Cable
Engineered for electrically noisy environments without the cost of plenum rating, this 18/4 shielded FPLR riser-rated cable features four solid bare copper conductors with aluminum mylar shielding and a CMR-rated PVC jacket. 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 in challenging installations near motors, electrical equipment, or high-traffic electrical areas—all at the economical pricing of riser rating for vertical runs and non-plenum spaces.
Proudly made in the USA and ETL-listed, this shielded riser cable delivers the interference protection of shielded plenum alternatives at a more cost-effective price point for installations where building codes permit riser-rated cable. Sequential footage markings simplify installation tracking and reduce labor costs.

Why Choose Shielded Riser Cable?
Shielded riser fire alarm cable combines interference protection with economical pricing:
- EMI/RFI protection at riser pricing - significant cost savings vs shielded plenum
- Signal integrity in electrically noisy vertical runs and standard installations
- Reduced false alarms by eliminating electrical noise pickup
- Code-compliant for riser applications with interference concerns
- Budget-friendly solution for noisy environments where plenum isn't required
When to use Shielded FPLR vs Shielded FPLP:
- Use Shielded FPLR (Riser): Vertical runs near motors/equipment, electrically noisy standard rooms
- Use Shielded FPLP (Plenum): Air handling spaces with interference sources, noisy plenums
Shielded vs Unshielded:
- Choose Shielded: Near motors, transformers, VFDs, high-voltage equipment, or electrically noisy areas
- Choose Unshielded: Clean electrical environments without interference concerns
Ideal for industrial facilities, manufacturing plants, hospitals, data centers with vertical cable runs, and any riser installation where electrical interference could compromise fire safety system performance but plenum rating isn't required by code—providing professional-grade EMI protection at economical riser pricing.
