For electronic alarms, I’d say the Wheelock MT set to continuous horn and the Gentex Commander 2 & 3 set to Mechanical tone. For mechanical horns, I’d go with the Simplex 2901-9833/FOS 6120+2903 and Federal Signal 450D+VALS.
What are the loudest fire alarms you have heard? These are mine, in order:
Spectralert Advance
Wheelock AS
Simplex TrueAlert
Gentex GX90 or other mini horns
EST Genesis or Integrity

Loudest I’ve heard was a E2S sounder on full volume, that thing shook the entire shed it was in…
If it actually made the structure shake, I would be concerned the shed is not very stable…

Is the shed made of sheet metal? If it is, that’s why it might be doing that. Sheet metal can resonate sound.

Nope t’was a wooden shed, but still, even outside the shed you could hear the E2S screaming.

Oh the structure was fine, just the walls started shaking like crazy, it wasn’t obvious but when you touched the walls you could feel the vibration.
But yeah that shed was temporary (the foundations weren’t permanent) a new and bigger one took its place and this time my friend tried to blast the e2s, it didn’t shake anything but the windows (oops)
I still have that e2s though (and it’s actually the AE&T T100 that I shown in my collection, it’s small but by far it can get super loud, I’m too afraid to run it at full power)
To be honest
3rd The Spectralert Classic w/ tile floors
Back in my elementary schools there were set to code 3. Extremely ear piercing
2nd The Spectralert Low Frenquency Sounder w/ concrete floors
At my friends apartments they were again set to
code 3. Not as ear piercing but still extremely loud
1st Simplex 4030/4903-9219
In my dad’s factory they had 4030s in the machinary area and the 9219s in the office area set on continous, worst pain in my ears EVER

- EST genesis damn near anywhere.
5(Tie). Edwards Adaptahorn, Simplex 4050 and 4051.
5(Tie). SpectrAlert series in a bathroom (yes this exists, I hate it too.)
5(Tie). E2S A100 (As Alex pointed out.)
5(Tie). L-Series standard tone. - L-Series 3 kHz tone.
- Wheelock MT.
- Siemens U-MMT.
On the contrary, here is the quietest: - Edwards pre-Int. electronic horn.
- System sensor CH series.
- Wheelock CH series.
- Autocall Executive Series chime.
The loudest I have heard has to be the simplex 9838, they had them at my elementary school, and they were crazy loud and they had strobe-less simplex mechanical horns at the end of every hallway but the simplex 9838s were louder but, now they have quiet system sensor ch series at my school.
One time at a hotel in Tennessee, the fire alarm went off, and there were ch series outside and Gentex remote horns inside the rooms, and those were pretty loud but as always the system sensor ch series was quiet.
I am in middle school now and they have pretty loud system sensor l-series but, in the new building, they have voice evacs.
now a ranking of all the alarms I have heard,
1- simplex 9838
2- simplex mechanical horn
3- system sensor l-series
4- Gentex remote horn
5- system sensor ch series

Sorry for the bump but the loudest alarm I have heard is probably a System sensor L series, My modded upphote alarm ripoff thingy. And an EST genesis.

At hampton elsamentry school and parish hill in hampton and chaplin both have very loud alarms but the sounds are diffrent.
Nice giant noisemaker! Is this a siren or a klaxon? Or it is just an electromechanical horn that runs on mains power?
Fanhai Sanjiang Electronics Co.Ltd. SG-991. My ears was almost crapped by it during a false alarm in a hotel. It generates an ear-shattering 120dB of wailing tone (fire truck tone) and emits powerful pulses of red light beam. Believe me, I don’t wanna experience that again…

I’ve only heard electric fire alarms. The loudest I’ve heard is the Gent C3. It has around 90dB and above. My elementary school (where I was many years ago) were placed quite close. There would be 3 in about a 60 metre hallway.

Yes. Some suppression systems have whistles or air horns or something alike. They’re usually connected between the primary agent bottle(s) and the delay bottle.
After the solenoid got tripped, extinguishing agent will first feed both the delay bottle, which builds up pressure slowly and then bypasses itself after typically 30 seconds, and the pneumatic noise-making thingy, which works as the final stage of evacuation signal. In some systems, a wintergreen odorizer will add strong smell signal to the gas shooting out.

yeah a tough one. it is sad that they do not make these mechanical horns anymore jeez. it’s kinda made out of metal or something.
My daycare had Wheelock NS’s on high volume. Those were LOUD.
