What does CI stand for in the context of fire alarm cabling?

• A. Circuit Integrity
• B. Circuit Interconnect
• C. Cable Interface
• D. Conduit Insulation

Answer: (A)

CI stands for Circuit Integrity. This refers to cables that are rated to maintain their electrical circuit under fire conditions for a specified period, so alarm signals and life-safety devices continue to function even as the building is exposed to heat and flames. That integrity is why these cables are used for critical fire alarm circuits. The other options aren’t standard terms used to describe fire alarm cabling ratings or functions, so they don’t fit the usual meaning of CI in this context.
