During a residential fire safety survey, what should be done with each smoke alarm?

• A. Replace all smoke alarms
• B. Test each one
• C. Leave them unchanged
• D. Remove them

Answer: (B)

Testing each smoke alarm during a residential safety survey verifies that it will actually warn occupants in a real fire. Pressing the test button confirms the unit is powered and its sensing and alarm circuitry are functioning, so you know the device can perform when needed. If a unit doesn’t sound, chirps, or has a battery issue, address it right away rather than removing alarms or assuming everything is fine—the goal is to ensure every device can reliably provide early warning. In practice, you go from room to room, testing every alarm, and also check that interconnected alarms all respond together if the system is wired to interconnect.
