The Ferrodos do not come with a wear sensor, no.
My pads were worn but the sensor didn't come on anyway.
There's a way round it. The sensor is on the left wheel, just cut the wire, tape it up and then join up, solder or use a paperclip on the other two wires.
Like I say my mate Ovni_Al did it so my knowledge is a bit sketchy, but there are guides on here. Use the search thingy...
