What alarm do you have at work/school

At school we have the loudest things on earth we have only the dreaded specta alert advanced ceiling mounts. And some of the classrooms had the walls chopped off so their are usually more that one sounding one in each room sometimes up to four soundin gin the same room. These things are so loud that i can stand like 40 feet away from the building with my ears plugged and i can still aer them I even have to plug my ears and i am the kind of person who dosent wear ear protection when im standing right next to an aca alertor 125 or a planer. but these things are just loud they are also in code three so its even more annoying and we have boring bg12 pull stations and their is this one that it like pulled almost alll the way and im scared that of somebody accidently bumps it it would set it off and i thinkt hat it will happn one day because it is right next to the entrance of our gym and in between the door and theirs a drinking fountain right next to the door and the ppull station inbetween its madness. We also have no fire sprinkelrs and no fire surpression. all we have are fire extenguishers. I assum that they work because they where inspected by the state last year and they will be prably newly inspected when i come back from iwnter break. So now you know what i have and also im wondering if bells are louder that those spectra alerts.
