'91 - I started kindergarten. That ES was built in 1975. I forget what the fire alarms were, but I remember being afraid of the noise. I think they might’ve been horns, probably either Simplex 4040s or 4050s, or Edwards 360s. The class bells were either Simplex/Faraday or Edwards 6" bells. I think they were mounted behind a flush-mount grille. That was my first time hearing a bell. Those were VERY loud in some of the smaller hallways.
'94 - the first fire drill for me in my 2nd ES, built in 1991. I was in 2nd grade. I don’t know what the panel was, but it had a Simplex system. The NAs were -9838s on 4903 strobe retrofit plates. This is the first drill I remember having and the first time I heard 9838s. Not too loud.
'97 - I was in 5th grade, in MS, which was actually 2 buildings connected together. One building, built in 1953, had Standard Electric 4-350 horns on Standard retrofit light plates, the same one wile_e2005 posted on the alarms at work/school thread. The other building, built in '56, had Standard 30A horns. That year was my first time hearing those horns. Those were loud as hell, especially the 30As.
'99 - I was in 8th grade, which at the time was the start of HS. That was built in '69, and they had an Edwards system with flush-mounted 360s. That was the 1st time I remember hearing those horns. Those were loud,but not as loud as the Standard horns from MS.
That year was also my first time hearing a voice evac system (it was a Simplex, with a code-4 horn tone) That wasn’t loud at all.
'00 - My HS was being renovated, so 9th grade was in the old MS building from '53 that year (the 2 buildings are now separated, and MS is now only in the '56 building, which was renovated in '99) The Standard horns were replaced with horizontal Wheelock ASs. That was my first time hearing an electronic horn (the AS) They must’ve been set on low, as they weren’t very loud at all.
That year I also heard the older MIZ horns for the first time, in a hotel room. That was loud.
'01 - I heard Wheelock NSs for the first time (in the MS. Those were loud.
Also that year was my first time hearing either a CP U-MHST or U-MMT in code 3 horn. Those were EXTREMELY loud!
'04 - the first time I heard either SAE 2DCDs or Simplex 9806s behind SAE retrofit plates. Those were also loud as hell
'07 - the first time hearing Gentex Commander 2s, in mechanical code 3. Those were also loud as hell.
I haven’t heard any new alarms in person since then.
