What are the key performance requirements a cable must meet to be considered BS 5839-1 compliant?

To comply with BS 5839-1:2017, a fire alarm cable must demonstrate enhanced fire resistance as defined by the standard, typically requiring the cable to maintain circuit integrity when tested in accordance with BS EN 50200 and, for high-risk areas, the more onerous 30-minute flame and water spray test of BS 8434-2. The cable should be rated as ‘standard’ or ‘enhanced’ depending on the anticipated fire duration, and must use low-smoke zero halogen (LSZH) materials to protect occupants and equipment in the event of a fire.
