2005 tf horn or sounder

Not having a working alarm sounder, ive checked fuses had pektron sorted and as i type sorted again. checked wiring fuses. Searched interweb till im sick looked at pictures under bonnet some show 2 horns some show 1 others speak of having one horn and a hidden sounder cant find that either. Can someone please answer the definitive question. is there supposed to be 2 horns or one horn or one horn and an alarm sounder. 2005 tf spark. If its just one single horn shared between steering wheel and alarm then its working from steering wheel but not on alarm side.................very confusing..............further reading of this site has educated me further
