My school is so old, it has the original one of these....1970? ,the school was built in 1929, and has a plaque from FDR, NYS governor. 1:39

[@Fahrenheit4051]

My elementary school was similar. The oldest part of the building (now demolished) was built in 1924, and the signals everywhere were the type at 0:43. They replaced these with a voice evacuation system sometime in the mid-2000's, and the signals are now SpectrAlert classic speaker/strobes. I would like to note that the Simplex 2903 was introduced in the early 80's, and thus weren't the original fire alarm signals at either of our schools. Pre-1970's, most systems operated on AC, and if the schools were built in the 20's, the original signals were probably large, black bells.

My high school had 4903-9101 strobe plates with 2901-9838 horns on them. The strobes were actually on the bottom part of the plate instead of the top. All were on continuous. One strobe plate even had a Wheelock 34t horn on it. This was all on a Simplex 4002 system. Btw, this was a school in Milford CT

[@Fahrenheit4051]

My middle school in West Hartford had them mounted the same way. Like the 2903's at Tunxis, some of them were on 4050-80 backboxes. The larger gym still had a lone 4050-80 left, with a low-pitched -9806. The same gym also had a 4003 with 4903-9101 + 2902-9713 speakers. You could hear the whoop just fine, but the voice message was unintelligible with the loud horn.

[@siphonralarms9411]

@@Fahrenheit4051 there was also a 4051 outside the cafeteria, I don’t think it was working anymore though. After my Junior year during the summer, the entire system was replaced. The 4002 was replaced with a Napco Firewolf addressable panel. All the 4251-30 pull stations were replaced with addressable Napco T-bar pull stations (stoppers were put over them), Napco addressable detectors replaced all the 2098 ones, and all the NAs were replaced with Spectralert Advance horn/strobes. They also added horn/strobes to each classroom (on high volume i might add) and everything was on code 3. So basically, my senior year fire drills had these screeching horns that I basically have grown immune to now.

My former Elementary School had those 4903-9101 2901-9838s. For some odd reason one side of the building that had the K-2 rooms had the strobes above the speaker and the other side of the building with the 3-5 rooms had the strobe bellow the speaker. Also I remember they used to just go off with a solid tone but one year they switched it to the three burst/pause/three bursts configuration and it stayed that way ever since.

Sounds like my middle school. Some units had the strobe above the horn, others had it on the bottom. And they were on continuous. The three-pulse pattern is called "code 3" or "temporal", FYI.

Oh this is awesome. I live in South Windsor, CT and have a very small collection of mechanical horns, since these were the alarms I had in elementary school and high school.

[@ZakWolf]

Only one you have that one of my public schools did is the Simplex 4051, which my first elementary (now K-8) school had. They were VERY loud. They were mounted on 4050-80 light plates, and that seemed to make them sound even more harsh. Unfortunately the old Simplex 4208 panel started failing over five years ago and so they had to come out, and now they just have SpectrAlert Advance horn/strobes...

Alright. Here's your answer! twitter.com/SpaceAgeElect/status/1116339019619680256 From the early 1970's! Those are just metal plates and not 4041's, but now we know the AV-34 was around at the same time as them. As for "bolding" an AV-34, they made one without FIRE lettering, so you could theoretically have decals printed out like they did for the upside-down TrueAlerts at Tunxis.

[@briansmith8361]

I am trying to determine what model horns were in my elementary school. I actually attended two elementary schools (Larchmont Elementary in Tacoma, Washington and Evergreen Forest Elementary in Lacey, Washington) and both used very similar or the same horns. I "THINK" they were Simplex 4050s or 4051s and they were extremely loud. When these bastards went off, I nearly had a heart attack! I remember one time I literally jumped out of my chair! The Larchmont school had them on a strange code, I want to say code 3 but there were FOUR pulses followed by a few seconds of silence. Rinse and repeat. So it wasn't on march time or code 3 to my recollection. Evergreen Forest's horns were set on continuous. At Larchmont, each classroom had its own ceiling mounted horn, and I remember the main hallway had at least one with dual projector horns. Evergreen Forest had all of the horns in the halls but close enough to the classroom inner door that you definitely heard them. This was in the 1980's through early 1990's, and these horns were probably outdated even then. Here's a hint: I know that more than a few of them had that adjustment screw visible on the vibrating metal plate. Any thoughts?

[@Fahrenheit4051]

The "strange code" sounds like code 4-4. Two rounds of four pulses, a long pause, and repeat. There's also the similar "code 4-4-4-4" which is the same thing but repeats four times instead of two. This code could often be found on very old fire alarm systems. If it had an adjustment screw directly on the plate, it was definitely an older Faraday-made horn (probably 5410 or 5640). These include rebrands like the Simplex 4051 and 4050. - Did the horns sound like dryer buzzers, or have a higher-pitched tone like the 4051 in the video? Only at one school? At both schools? - Were there some horns where this screw was noticeably absent, and did those horns have a round plate instead of a square one? - Were the horns on the double projector square, or triangular? This isn't super important as it could a be mix-and-match.

No offense to you alarm enthusiasts out there (I'm a mechanical siren enthusiast myself) We had one that sounded like the first one at our school, but looked like the one at 2:28 except flat with beveled edges. I'm not sure if it's how the alarm was designed, or maybe they had their volumes turned up all the way, but they were deafening being within 10 feet or even more. They had them in our bathrooms at ear height. We had to walk past them to get in and out of the bathrooms as it was an L-shaped hallway to get inside, and there was no way around this. (Practically forcing us to be within 1 foot of this thing at ear-height.) My brother almost lost his hearing when he was in the bathroom once and one of these things sounded for a drill. Our school is mainly autistic kids, myself included, and sudden loud sounds aren't really something that our reactionary systems can handle well. I got acute PTSD from it. It got so bad that my principal offered to tell me when they'd be doing drills so I didn't have to deal with being jumpscared by a deafening sound. She'd give me her keys and I'd go out and sit in her car and wait for everyone to walk out to join them. My acute PTSD went like this: I'd be sitting in a quiet space, and all of a sudden my mind would send me into a psychotropic trip where the alarm from our school suddenly goes off despite it not being anywhere around me, then it would go away. I'm really hoping it was a setting or something, or that the alarms they used were meant for large areas thus they were just misusing them, because I can't imagine why they'd be designed to be so deafening.
