FyreLine Analogue Nylon, SS LHD Cable


Key Features

  • UL 521 approved and compliant with the EN54:22 draft standard
  • Self-restorable analogue type system with optional pre-alarm setting
  • Cable based sensing allows detection at the point of risk
  • Low installation, maintenance and repair costs
  • Reliable solution for hazardous areas


A Nylon coated cable is the common choice when hazardous hydrocarbons such as fuel oils, diesel, kerosene etc. are present. Nylon cables are coloured black and provide suitable UV protection when used in direct sunlight. Nylon is much tougher than PVC and therefore provides additional mechanical protection. An additional stainless steel braiding over the outside of the cable is included thus providing protection for areas where the cable may be accidentally cut or where it may be subject to mechanical abrasion.


The FyreLine analogue linear heat detection cables are fully approved by the Underwriters Laboratories (UL) and bears the CE mark to show that they comply with all the applicable Directives including the CPR, EMC and the Low Voltage Directive (LVD).
