Escape Room Props Hold Hands As Bridge to Unlock Support 1-5 People Exit Game to Control 12V EM Lock

The usb interface to change audio files is not being recognized on computer. how can i get it to come up to change audio files?

Can you splice in longer wires to make the distance longer?

Hi, I'd like to order the version that includes a speaker / allows custom audio files. Is that available? It seems that this one just has the buzzer?
