When are fire alarms to be installed in a new home?

• A. During rough-in stage
• B. After all construction is done
• C. Before any construction starts
• D. Once occupancy occurs

Answer: (B)

The timing centers on doing the fire alarm pre-wiring while the house is being built, specifically during the rough-in stage. At this point, walls and ceilings are open, so wiring can be run easily to each area, back boxes for detectors can be set, and the interconnection of alarms can be planned and tested before surfaces are finished. This ensures proper placement (in bedrooms, hallways, and outside sleeping areas as required by code), reliable power or battery backup, and a fully interconnected system without damaging finished walls later. Waiting until all construction is done would require opening finished walls or ceilings to install or modify wiring, which is costly, disruptive, and often impractical. Installing after occupancy is even more problematic for the same reasons. So the recommended time is during rough-in, not after construction is complete.
