This key can be used to request help in restrooms, report theft, give early fire alerts and for many other applications.
The SOS key is most often used in restrooms of medical and accommodation centers; it connects via a 4-pair cable to the request display located at reception. Pressing the SOS key shows the room and floor number on the display and announces it by voice so help is dispatched to the announced location.
