A simulation of my high school's fire alarm system. I think the original system was a Siemens system judging by the EHS series alarms. Other than that, it's your usual TrueAlerts and MT's. Pretty loud...
I fixed a few sound files recently, so they should sound better than ever. Sorry for the raspy bell sound effect. It's too loud for the website to handle, and I don't know how to fix that. You get the idea though.
