UHHHHMMMMM. Locate the wires that go to the speaker, cut them, make them longer if you want, then connect it directly to some kind of audio output and play a continuous tone. This is really the only way to do it. Basically you are converting it to a Speaker/Strobe. If you really don’t care about the module, try messing around with the tone generator to see if you can short it on some way to out out a continuous tone. It is very unlikely so my first suggestion is probably best…
let me know if that helps!
