each fan has a separate switch.

Then I will show you that there are many fans in this mosque, each fan has a separate switch. I am giving a picture of the fan here and also a picture of the switch board. Then I saw that two sound boxes are installed, these sound boxes are used during every prayer. Because the Bazaar Station Mosque is always crowded with people, so the sound box always has to be used. Using a sound box benefits everyone. Because those who are at the back often cannot hear the sound, so the sound box is used to make it easier for them to hear the sound.
