This standalone coaxible cable is certified to meet the UL 2196 Standard for Fire Test for Circuit Integrity of Fire-Resistive Power, Instrumentation, Control and Data Cables. Visit the DragonSkin Cable Website: www.dragonskincable.com

FEATURES / BENEFITS

  • First UL Listed standalone communications cable meeting NFPA 72 and 1221 survivability standard
    Verifies the cable survives 2 hours at temperatures up to 1,850 degrees F and the water spray test without conduit or additional wrapping
  • Enables cellular and public safety radio communications to and from all floors of a burning building
    Ensures emergency responders and building occupants have reliable access to communcations during fires
  • No conduit or cable wrapping required
    Reduces cable size and weight; simplifies installation
  • CATVP plenum-certified
    TMeets certification for use in the environmental air handling space in buildings
  • Coaxial cable features solid inner and outer conductors
    Virtually eliminates intermodulation
  • Maintains minimum bending radius at all times
    Accelerates installations, especially in smaller spaces and older buildings
  • Uses standard RFS Technologies connectors and installation techniques
    Eliminates the need for specialized parts or expertise
