Fire Alarm Control Cable

Galvanized Interlocking Steel Armor Color Coded Red featuring ColorSpec®®

Features & Benefits

  • Red armor identifies Fire Alarm® Cable
  • Type FPLP or Dual-Rated Type MC/FPLP is plenum rated
  • Available with twisted shielded pairs
  • Superior EMI Shielding versus aluminum armor
  • UL® Classified for Through-Wall Penetrations
  • Fire Alarm®/Control Cable is a traditional Type MC cable containing one or more copper grounding conductors; the armor is not an equipment grounding means
  • Made in USA of US and/or imported materials

  • 1 In Steel Armor
  • 2 To correct for 90°C, multiply by 1.048
  • 3 Effective Impedance is defined as R cos (Theta) + X sin (Theta) where Theta is the power factor angle of the circuit. Effective impedance values shown in the table above are valid at 80% power factor.
