Non-fire alarm system components may share fire alarm wiring on a combination system.

Non-fire alarm system components may share fire alarm wiring on a combination system.

• A. True
• B. False
• C. Only with special approval
• D. Never

Answer: (A)

On a combination fire alarm system, non-fire alarm components can share fire alarm wiring when those components are designed and approved to operate on fire alarm circuits. The fire alarm wires carry signaling and supervision, so using the same cables is allowed if the non-fire devices are listed for use on fire alarm circuits and the authority having jurisdiction approves the arrangement. This setup can save on wiring and installation costs while maintaining reliability because the circuits remain monitored and faults are supervised. The key is that sharing is permitted only for equipment specifically designed for this purpose and compliant with the relevant codes and standards; devices not intended for fire alarm circuits or installed without approval should not be connected to the same wiring.
