Q. Hi will this make a noise if connected to a battery or does this need to be connected to an output signal form a chip of some sort? Thanks
A. Hi Mark, thank you for your question. This requires a signal applied in the region of 7KHz and no more than 30V peak to peak to operate (a little bit like a tweeter), normally it would be a buzzer you would require to work direct with a DC voltage from a battery.
