Siren question - OnStar commercial

In the following OnStar commercial, the fire department responds to a car accident dispatched by OnStar.

At about 22 seconds as the garage door is opening, you first hear a siren. It's a really low tone before it winds up.

I know it's a long shot but does anyone know what tone this is and who makes this siren?

Thanks

Sounds more like my PA20A when it starts up. Vidoe is not mine but you can hear one here.
