What action should be taken if lavatory smoke indications are no longer present?

• A. Pressing smoke reset outside lav or on FAP
• B. Notify the captain
• C. Close lavatory door
• D. Ignore it

Answer: (A)

When a lavatory smoke indication has latched but the indication is no longer present, you reset the system to clear the alarm and re-arm the detector. Pressing the smoke reset button outside the lavatory or on the Flight Attendant Panel performs this action, ensuring the detector is ready to alert again if smoke recurs. This keeps the system accurate and avoids confusion from a lingering latched alarm. If you don’t reset, the alarm can remain in a latched state even if the area is safe, which could delay a real check or future alerts. The other options don’t address re-arming the detection system and aren’t the prescribed immediate action.
