Some aircraft have a red guarded Smoke Detector switch
for each lavatory located at the adjacent Flight Attendant
panel. Move the switch to the OFF position.

(Continued)
If the red guarded smoke detector switch is not installed, locate the smoke detector unit under the sink area or in a compartment between the sink and toilet. Disconnect the cannon plug located on the smoke detector.
The affected lavatory must be locked and not used for the remainder of the flight. Make a logbook entry.
