Hi
I found this buzzer in a carbon monoxide alarm I was throwing out.
Must be 10 years old or so It was powered by 3-4 AA batteries.
Its has 3 pins marked F G M
Markings (Made IN Korea by SUN JIN) no part number.
I am trying to make it
buzz , want to add to an alarm i am making.
I been doing a bit research and found this circuit, I set it up but nothing happened.

thanks
