alarm siren with 4 wires, why ?

i have an alarm siren with the regular wires going into it ,  black and red normal gauge ...and then some (2) really thin black wires   what would this be for ???   the model # on the sticker says : au-72   made in taiwan .   patent pending .......   it is a little older , came out a car a freind bought and he didnt car about alarms so he took it out along with the complete alarm but he just cut all the wires so i cant trace anything .  anyone seen this type of alarm siren ??

They are either trigger or they could be the loop wire for siren volumeWOW Sight and Sound

Nothing is impossible!

Do it right the first time or don't do it at all.

i see now that its not 4 wires , but the smaller wires used to be a loop .   it was cut ,   can i reconect it ??? whats the loop for ???  a volume ??? 

It is an Omega/excalibur.If I'm nor mistaken it's for the chirping function. With the loop and short burst (chirp) is not as loud as a full activation. Cutting it makes a full volume chirp.

 Yeah what Floaterr said. It only effects the loudness of the chirp when is triggered. Cut its louder uncut (or in your case reconnected) low chirp.

UHH .......yep.......MO
