What is a requirement for coaxial cables entering buildings?

Coaxial cables entering buildings must be separated from lighting conductors to minimize the risk of electromagnetic interference (EMI) and ensure signal integrity. This separation helps prevent electrical noise generated by lighting systems from affecting the performance of the coaxial cable, which is especially important for maintaining clear communication and data transmission in fire alarm systems and other critical infrastructure.

Additionally, keeping coaxial cables at a distance from lighting conductors also adheres to safety standards and regulations, which dictate appropriate installation practices to protect both the cables and the overall electrical systems within a building. Maintaining this separation supports the reliability and functionality of fire alarm systems by ensuring that they operate correctly without disruptions caused by other electrical components.
