Worked with that same system for over 35 years in a Skilled Nursing Facility. Was very dependable, few problems and there was no way to miss those horns.
I have these 9838s at my school, which was built in the 1900s. Fortunately, the alarms are in the hallway. Unlike some schools, which have one fire alarm in every classroom
I found that the Gaylord Opryland hotel is Nashville has these exact simplex 2903 light plate fire alarms. A couple of them have been replaced with True alerts and 4903 horn strobes but many of these original light plates are still in this hotel
It's like Music Notes. It goes by A B C D E F G and depending on the pitch, it can be either Sharp or Flat. The original comment up there is trying to say that the Alarms had different pitches.
@@joeycaridi3030 There's a metal tab that you can move up and down to adjust the pitch. The same thing can be done with the early models of the Simplex 4903s. Only you have to use an allen wrench to adjust the pitch.
@@joeycaridi3030 There's metal tabs that you can adjust to change the pitch of the sounds. This can also be done with the 4903 series as well. Only difference is you loosen or tighten the screws on the horn.
You mean figure out what the pitch is? Or an interval, or a chord? I hope you don’t fall yourself a professional musician, unless you know your music theory
I honestly dont know why they put a horn sound in these like you would be able to hear it if there was a bell or a whistle or anything else but they had to put a horn in because thats all people can hear nowadays
@@FireRescue80 no. I was not wearing any. This was a real alarm so that was why the video was fairly short. Luckily it was just smoke from a units kitchen
As the horn sounds each time during a fire alarm condition, the sounder plate warps over time and that's what changes the pitch. The closer the metal disc is to the sound plate, the higher the pitch. The farther the metal disc is to the sounder plate, the lower the pitch. When they begin dying, that means the contacts have been corroded because of them vibrating so long. Or it could be because the contacts need to be adjusted.

same with my school because its too loud so they put it in the halls
Those are really heathy sounding considering their age.
Simplex honkers age well.
Heathy
Don't all them sound like that?
0:46 that is one of my favorite fire alarm
my favorite horn 0:13
Same
I literally watch this over and over just because I like the sound of Simplex mechanical horns...
lol :)
Me too people should make more of these
yeah i agree because they sound a little quiet :)
Same.
The horns sound neat even the true alerte and M3
What a beautiful sound
Those alarms sound so cool
BEEP BEEP BEEP
@@ambercockrum3708 KAPO I just wanted you
Love how the sound of the alarm gets lower in octave every floor
I always found that interesting back then. Could never figure out what caused it

There is no way a person can make A sound of a fire alarm
Dang, those things sound new! You rarely hear mechanical horns that sound that good anymore.
Yep
They're all over my school-
Yep!
1st alarm key: C
2nd alarm key: C#
3rd alarm key: C (off pitch)

Interesting how all the same mechanical horn can all have their own pitch variances!
I know right!
Are there any settings on the back of the alarms to change the pitch in semitones. Or they pre adjusted by simplex.

These were the fire alarms my high school had
I love the sound of those alarms 💯👍😎
Your lucky cuz I got those ones that are inside your room, the first time it happened it. Was pure hell it was 11pm btw
quantie we got simplex horns in the apts (which I think are disconnected) and there are like smoke detectors now
At least it wasn’t coded to continuous
Matt Johnson it was coded to code three...
That is cool
That would give me a headache 🤣
I love simplex horns withe these light plates
I kept trying to find a harmony note to every alarm on this video

lori del valle thanks
Sorta sounds similar with the hall way alarms with the other ones reminds me of my old school but i think it was strobe lights
CA in a nutshell during wildfires: Fire alarms going off every minute, people screaming
nobody was screaming.
covered in shit too.
The strobe says fire, fire on each side
WOW SIMPLEX FIRE ALARMS BEST FIRE ALARMS
I’m glad those fire aIarms 🚨still work
I have those same exact alarms at my apartment but instead of going du, du, du, it goes duuuuuuuuuuuuuuuuuuuuuuuuuu
The fact you go near more fire alarms and they just get louder..
When you pause the video but you still hear the alarm...

It is very simple!!!

Sorry,I not goot at English...
Are they still in use as of today?
FriedFrudda yes.
I actually love it when the old mixes in with the new.
Do you know Old School Fire Alarms channel? The Simplex 4030 is my most favorite.
I like how the lettering is on the light. It's as if it's saying "Fire! Fire! Fire!"

those are so rare
the stairwells were a bit quiet. Notifier ftw, soo ez to use. simplex and fire-lite are ok. Edwards are the devil.
brian bowen there were not any horns in the stairwells. It’s echoing from the walls.

Woah

My favourite fire alarm 🚨 is gent vigilon
Why do they have all different pitches?
Because as the horns age the pitch changes. That is what I've heard many times
As the horn sounds each time during a fire alarm condition, the sounder plate warps over time and that's what changes the pitch. The closer the metal disc is to the sound plate, the higher the pitch. The farther the metal disc is to the sounder plate, the lower the pitch.
