  • The cable is marked with the phrase "Fire alarm cable” at regular intervals on the sheath. It is therefore used especially for installation in fire alarm systems.
  • Aluminium-laminated plastic foil static screen with tin-plated drain wire minimises the interference of high frequency, electromagnetic fields
  • Decoupling of circuits by means of
    twisted-pair (TP) design (crosstalk effects)

Application range

  • This installation cable is used to transmit signals.
  • For fixed installation on and under plaster, in dry and damp rooms
  • For outdoor use this cable should be installed under plaster only
