In some luxury hotels, there are elements whose use often remains unknown to guests. Recently, a video went viral on social media in which a person demonstrates a specific switch and grille in their hotel room, asking about the purpose of this system.
The video, shared by user youreaxmbuddy, shows a system installed on the wall in the room. Although this construction externally resembles ventilation equipment, users in the comments express confusion about its true function.
After the video became popular, people began making suggestions in the comments. One user suggested that the device was intended for communication with the reception. Another assumed it was a ventilation system. However, one user's opinion received wide approval and recognition for its awareness.
This user clarified that this button is a 'Do Not Disturb' function and simultaneously serves as a doorbell that can be activated or deactivated. Activating 'Do Not Disturb' mode prevents the sound from the doorbell from entering the room if the guest wishes to remain undisturbed.
This explanation was accepted by most as the correct answer. Internet searches reveal many different models of doorbells that have a similar appearance, suggesting that this is part of a doorbell system. It should be noted that some hotels also install similar grilles as gas analyzers, but such devices are usually not accompanied by such a switch.
