BS7846 – F120 (Enhanced)

Special fire resistant cables designed to survive and operate during arduous fire conditions. These are designed as per BS 7846 standard and are LPCB approved for F120 fire test as per BS 8491 standard as well as BASEC approval.

 

Cable Uses

  • Fire Alarms
  • Fire Detection
  • Hospitals
  • Large Buildings
  • Railway Stations
  • Schools
  • Shopping Centres
  • Sprinkler Pumps

Fire Standards

As described in BS 8519, fire resistant cables are classified for Life Safety and Fire Fighting systems with different fire survival time of 30 minutes, 60 minutes or 120 minutes. These cables meet the 120 minutes fire survival test. During the F120 fire survival test as per BS 8491 the cable sample is subjected to fire and mechanical shock with direct impact on the cable as well as being subjected to high pressure water spray. For more information, please visit Fire Standards
