Mallory Sonalert: how to wire?

Issue*

I just picked up a Mallory Sonalert audio indicator but have no idea how to wire it.

I got the part from Mouser (product page) but the data sheet is pretty uninformative (data sheet link)

What I was expecting
I was expecting to have a two inputs, like all the other buzzers I have, but this instead has three pins, labeled G, F, and M.

You can see it here:

Question

How do I wire this, given that it is not + and -, but G, F, M?

See image:
You can also drive it with an Arduino output pin connected to M with G connected to GND.
Use TONE of 3400HZ.

I think the sonalert is a product with internal driver. all you can do is to add power or remove power.

it contains a piezoelectric buzzer but I think you cannot address it directly. that is why it is a sonalert and not a piezoelectric buzzer.

That's a terrible "datasheet" I even found mallory's site and put the part number in as a search but got no more.

However, with a bit of googling "piezo sounder g,f,m" I found this interesting thread that may answer your question.

Edit: Ooops. forgot the link
Here it is

Greetings,

Fwiw, here's a link to a data sheet for another model from Mallory that corroborates KenF's link.
