Fire protection cables should be installed in separate cable trays
Dedicated Cable Trays/Ladders: Use completely separate cable tray systems for fire-resistant and ordinary cables. 5 meters between. UK electrical and fire safety standards do not prescribe a fixed minimum separation distance for roof-mounted life-safety cable trays. However, BS 7671, BS 8519, and BS 5839 collectively establish that life-safety circuits must be installed on dedicated containment and be either separated by. Data and signal cables should be segregated from power to reduce electromagnetic interference. Fire alarm circuits must be routed independently of other services. The core reason boils down to three lifesaving principles dictated by both safety logic and stringent codes like GB 50016 and GB 55037. Core Function & Safety Requirements: A Fundamental Difference. Mechanical protection – cables must be protected against physical damage, abrasion, and improper handling. Compatibility with the environment – correct ratings for plenum spaces, risers, outdoor areas, and corrosive or damp locations.
