Buzzer(?) on 48VU panel A320

Can't find anything about it in the FCOM. Looked in the maintenance manual but couldn't find anything to help. Even Google is not being much help!

To the left of the "Toilet occupied" light on overhead panel 48VU, there's what looks like a buzzer. Is that what it is? If not, what is it?

It’s the evac horn

I remember asking one maintenance guy and he had no clue lol. Could it be the buzzer for the emergency evacuation alarm?
I’m flying with a maintenance guy on board tomorrow. Hopefully this one will know. I will keep you posted if I get an answer.


EDIT: Oupsy! EGPFlyer posted while I was typing! xD
Well now we know. Thanks!
