A. Hi Paul, thank you for your question. We have checked with the manufacturer and they have confirmed that these are in fact not polarised.
This piezo transducer is able to generate a range of audible tones and frequencies when energised by a 12V peak square wave. Provided it is mounted rigidly in the prescribed manner, outputs of up to 80dB can be achieved.
