Why does the bell sound when the light is turned on?

Eugenia asks:
2 times it was like this: turn on the light in the hallway, at the same time, by itself, within a split second, the bell rings !!!

The 1st time when I turned on the sconce, working from the outlet. Another time - when you turn on the chandelier. Changed the electric meter. 1 time was with the old counter, the 2nd - with the new one.

Is such a situation dangerous? Where can there be a problem in the wiring? Is there anything to do? thank

 

The answer to the question:
Hello! If this were constant, then the problem is clearly that the light and the bell are interconnected. But since this happens rarely and, as you write, for a split second, the question arises: what call? Is it plugged in? How is it connected? I think that when the light is turned on, interference may occur, which leads to a short-term response of the call. Most likely, everything is in order and nothing special can be done about it.
