Requirements for cables in fire protection distribution boxes
What are the requirements for cables to minimise the spread of fire? To prevent the spread of fire between fire segregated compartments, cables shall be installed in accordance with Section 527 of BS 7671:2018. 1 or cables with resistance to flame propagation according to the recommended requirements of the relevant part of BS EN 60332-3 series or, where. Correct cabling practices are fundamental to the reliability of life safety, security, and electrical systems. Poor segregation, inadequate fire resistance, or unsuitable fixings can compromise both system performance and occupant safety. The principal reference standards are: BS 5839-1:2025 - Fire. All cables for fire alarm, security, signaling systems, and emergency communications shall be shielded twisted pair cables or installed to comply with the performance requirements of the system. The 2016 amendment 1 to BS EN 50575 states that from July 2017 it was obligatory for cables to be accompanied by a DoP (declaration of conformity) and inc ude a CE mark. What this means, is that only.
