Model 4000: Perimeter Fire Curtain Performance Standards

The Model 4000 Perimeter curtain provides unsurpassed flexibility when it comes to fire protection and open atrium design.

Until now, meeting fire code requirements in atriums meant corner posts or columns were needed. However, the new Model 4000 perimeter curtain creates an enclosure of fire-rated curtains surrounding large openings such as a grand staircase without the need for corner posts or columns.

Despite being a great benefit to design, the Model 4000 is most impressive in its effectiveness. The Model 4000 maintains the following performance standards:

  • 120-minute UL 10D “Fire Tests for Fire Protective Curtains”
  • 20-minute UL 10C “Positive Pressure Fire Tests of Door Assemblies”
  • 20-minute UL 10B “Five Tests of Door Assemblies”
  • 20-minute NFPA 252 “Standard Methods of Fire Tests of Door Assemblies”
  • UL 864 “Control Units for Fire Protective Signaling Systems”
  • ASTM E 84 Class A “Surface Burning Characteristics of Building Materials”
