Please don't disturb the hotel room, please clean it immediately. What is the wiring of the doorbell?

There are generally two ways to connect. One way is to ring the doorbell switch when "Do not disturb". The other one doesn't ring.

Let me give you the route map. Figure 1 ring, Figure 2 is silent.

Don't disturb is rest, you don't need to clean, and don't let others disturb you casually.

Please clean it up immediately. It means cleaning.
