Engineered for 2-wire circuits in electrically noisy environments without the premium cost of plenum rating, this 18/2 shielded FPLR riser-rated cable features two 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 for notification circuits, audio systems, and control applications in challenging electrical environments—all at the economical pricing of riser rating.

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 2-wire installations in vertical runs and non-plenum spaces. Sequential footage markings simplify installation tracking and reduce labor time.

Why Choose Shielded Riser 2-Conductor Cable?

Shielded riser 2-wire fire alarm cable offers the best value for simple circuits in noisy environments:

• EMI/RFI protection at riser pricing - significant cost savings vs shielded plenum
• Simplified 2-wire installation with interference protection
• Signal integrity for notification and audio circuits in electrically noisy vertical runs
• Reduced false alarms by eliminating electrical noise pickup
• Most economical shielded option - 2-conductor with riser rating

When to use Shielded FPLR vs Shielded FPLP:

• Use Shielded FPLR (Riser): 2-wire vertical runs near motors/equipment, noisy standard rooms
• Use Shielded FPLP (Plenum): 2-wire circuits in air handling spaces with interference sources

Shielded 2-Wire vs Unshielded or 4-Wire:

• Choose Shielded 2-Wire: Notification/audio circuits near motors, transformers, or electrically noisy areas
• Choose Unshielded 2-Wire: Clean electrical environments without interference
• Choose 4-Wire: When applications require additional conductors

Ideal for notification circuits, audio systems, simple control applications in industrial facilities, manufacturing plants, and any 2-wire riser installation where electrical interference could compromise system performance but plenum rating isn't required by code—providing professional-grade EMI protection for simple circuits at the most economical price point.
