18/4 Shielded Plenum (FPLP) Fire Alarm Cable
Engineered for electrically noisy environments, this 18/4 shielded FPLP plenum-rated cable features four solid bare copper conductors with aluminum mylar shielding and a low-smoke PVC jacket for safe installation in air handling spaces. 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.
Trust ETL-listed, USA-made quality for your critical fire detection systems. Sequential footage markings simplify installation, while the shielding safeguards against system noise that could compromise life-safety operations when every signal counts.
