Understanding the distinctions between functional earth and protective conductors is vital for fire detection and fire alarm system safety and functionality. Our latest technical bulletin delves into the critical roles these conductors play, detailing the unique colour coding standards that prevent misidentification. You'll learn how pink sleeving identifies functional earths, ensuring proper operation of fire detection and fire alarm equipment, and how green and yellow sleeving denotes protective conductors, safeguarding against electric shocks. By following these guidelines, outlined in BS 7671 and BS 5839-1, you can ensure the integrity and safety of your fire safety systems.
