Power-limited fire alarm circuits in hoist ways must be installed in

• A. RMC, NMC, IMC, or EMT
• B. PVC conduit
• C. Rigid steel conduit
• D. Nonmetallic conduit

Answer: (A)

In hoistways, power-limited fire alarm circuits must be run in a protective raceway to guard the wiring from physical damage and harsh conditions inside the elevator shaft. The code allows a range of conduit types for this purpose: rigid metal conduit, intermediate metal conduit, electrical metallic tubing, and nonmetallic conduit. This means any of those listed raceways is acceptable, giving installers flexibility to choose the best option for the installation. The other choices narrow the options to a single type (such as PVC or rigid steel only) and don’t reflect all approved raceways, so they don’t meet the requirement.
