Fire Alarm Going off in My College Dorm

We all know how Michael Scott loves to wake up to the smell of crackling bacon in the morning. Meanwhile, I had to get up to the sound of a fire alarm being activated by crackling bacon. My dorm has a Simplex 4906 Truealert Era Horn strobe, upstairs is a Simplex 4903 that is upside down, and our entrance has a First Gen Wheelock LED Exceder horn strobe. This dorm complex predominately uses Simplex 4903's now. All are upside down so they put FIRE stickers on them. The 4906 may have replaced something a bit newer (maybe a 2903) but odds are, with the Simplex 4251-30 pull stations, there maybe have been Simplex 4051/4050-80 horn strobes way back when this dorm was built.
