Fire Resistant Power Cable BS7846 – F120 Enhanced

 Description:

 Application:

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.
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.

• Areas where there is a high concentration of people eg. schools,
shopping malls, railway stations etc.
• Services where circuit integrity is very important under fire conditions eg.
special equipment in hospital
• Essential safety circuit eg. fire detection, fire alarm etc.
• Power supply to equipment used in fire-fighting eg. sprinkler pumps
• In large buildings where fire strategy involves evacuation of occupants in
phased manner.
