Question: To satisfy the annual functional test requirement for smoke detectors, what action must be performed?

Answer options: ✅ Introduction of smoke or smoke simulant into the chamber

• Activating the internal magnetic test switch
• Measuring the voltage across the SLC loop
• Pushing the 'Test' button on the detector body

Correct answer: Introduction of smoke or smoke simulant into the chamber

Explanation: Section 5.7.4.1.2 requires testing smoke detectors by introducing smoke or a smoke simulant into the sensing chamber. Using a magnet or test button only tests the electronics, not the entry of smoke.
