@omeletteaufromagenoir Besides, literally every other WTC related video on TH-cam has already been filled with such discussions, so I am pretty sure they'll survive without this one. So far the only response I've been met with from them is extremely hostile, so no one will miss them really. They can have the other video's while the rest can maintain a civil discussion here about a subject we collectively cherish.
Yeah it is actually a good idea to blacklist any comment containing words that hint towards conspiracy theories. You could do that in TH-cam Studio and any comments matching those words won't get published until you approve them
The voice on the first alarm is chilling: “A fire emergency has been reported in the building.” Given that the buildings were hit by 767s and roughly 10 floors were on fire, that’s an understatement. It’s crazy to think that some people towards the bottom didn’t feel the jet impacts and the electricity, water, telecom, etc., continued to function. That’s how huge those buildings were.
@@daftdan8589 FCP looks vaguely like the WTC twin towers (lobby esp.), but it could have been the MTCC, the convention centre, which is directly beside the CN Tower and *ahem* SkyDome, and seems to have been built closer to the time of WTC7.
I know it's just a sound, but the WTC7 is the scariest sounding alarm I've ever heard. That would explain how the building was vacated so quickly. I don't how that lone Secret Service remained there alone.
In the longer version of Melissa Doi's phone call to 911 there are moments in which you can hear the fire alarm in the background. So glad the dispatcher stayed on the phone with her to the end.
I came here after hearing the WTC7 alarm in some documentary footage taken shortly before it collapsed. That sound is... creepy, unsettling, haunting. The part with two beeps is the creepiest part for me, for some reason, but the whole thing fills your soul with dread.. I've never heard an alarm like that before. Nor have I ever felt compelled to look up an alarm sound until this one.
I think thats on purpose. Sure everyone knows thats on purpose, but let me explain further: i think the one who designed the sound, knew, that New York is filled with a lot of sounds, noises, beeps, etc.. So he had the hard task to design a alarm, which not only distinguish itself by every other possible sound in New York, but also sounds so much serious and horrifying, that everyone in that building would take it serious immediately. The sound sounds so easily designed, but it isnt. Not only the pitch is very well choosed, not to low, not to high (its in the sweet spot of the highest sensitivity of the human ear . The ear is less sensitive for higher notes, as well as for low notes). The 'attack'' (first 100 ms of the sound) is also very well choosed, which makes this ''hammering'' noice in the beginning of the beep. It literally alarms the body , because of that hammering uneasy feel. The sound designer also choosed a sawtooth-waveform, which in a subtile way differs from a piano-note. Also the rhythm of that noise is in the pattern of a heartbeat, with a long release-phase (like an echo or reverb of the noise). Everything of that sound is made to take actions, way before people smell smoke, or see fire. Its really very intelligent psychological sound design. Thats why in the comment section a lot of people point out that sound, and describe it as creepy , eerie, etc.
@@PygmalionFaciebatThat is a very good assessment of this alarm. I also was thinking something very similar to what you were saying about how it seems simple, but someone probably put a lot of thought into its sound, and did so intentionally to better establish a sense of urgency when it sounds. This is probably the one alarm people would hear and actually think twice about it (except for just finding the alarm annoying). I've seen typical alarms going off in public places like malls and even airports and they just are ignored. It's so a-typical of an alarm you'd never forget it. Also notice how it's not ear shattering loud like almost every alarm, the two people are able to have a conversation without the alarm over stepping them. Quite a fascinating thing, but I could also just be overthinking it. Would be interesting to hear from the people who designed it where the idea came from.
I can hear that ping sound at 1:30 in a lot of documentaries and I had no idea it was only for building 7. I thought it was coming from building 1 or maybe 2
@AA The chime sound was there to notify about a fire related incident whereas the whoop signaled evacuation. Firecom still provides the alarm system for the current WTC complex, and there's a video in which someone films the alarm going off within the transportation hub. Albeit a slightly different tone due to it of course being a newer variant, Firecom still utilizes it. There were no alarms associated with the destruction of buildings as such since not only because such scenario's are too specific, it would also defeat the purpose of what an alarm is for; to notify about ongoing hazards within the confinement of the building itself. WTC 7's alarm got triggered after the collapse of the South Tower, presumably due to the vast amount of smoke entering the building. Lastly, the chime sound can be heard within Mark LaGanga's video of WTC7's lobby. The North Tower was still standing at that point.
@@DylanKevilleSirens The video title is "Fire Alarm Activation at One World Trade Center in NYC" (no quotations). You'll hear a triple chime repetition with voice assistance.
Kinda bizarre that you were able to find this. I never thought I'd EVER hear the isolated alarm sound from building 7. In general there's not a lot of photographs or info pertaining to 7 in general
my mom was working in an airport the day that this happened. She wasn’t scared, but my dad and sister were pretty worried. I wasn’t born when this happened, so it’s interesting to see stuff like this and other videos and what actually happened. Easily some of the most terrifying things I’ve ever watched on TH-cam.
Dude, you have the same thoughts as me pretty much haha. I wasn't born in 2001 either, my parents always told me what it was like on the day of the attack in the USA, here in Brazil. Here in Brazil, my completely desperate grandmother picked up my mother from school, thinking that this could happen here in Brazil. My father still lived on a farm, he was in a local business watching on a small television, all the news being interrupted to give the news that a plane had collided in WTC 1. Soon after, my father reported that he saw the second aircraft hit the other tower. And so it was for the rest of the day, following everything about 9/11 in 2001 on that commercial television my father was on... It must have been something shocking to have followed that. I'm very excited about all this, it gives me something inside me, I've always been one to research and find out more about 9/11. We can say that since 2001 until today I have been very interested in looking for everything about this regrettable event. Whenever possible, I always watch videos, read articles from the USA and Brazil about the event, I go very in-depth about it, and I always look on the internet for possible things that remain from 9/11 today. This interests me a lot. Hugs here from Brazil💪🏻
I've been going through the comments and its surprising how clean you've kept them, that and you know a lot more about alarm systems than I do. Good job
Thanks! Doing my best to keep the place tidy for those who want to learn about and discuss the subject. I've learned quite a bit form the people in the comments here and even noted some inaccuracies based on their input. There aren't that many places where enthusiasts can discuss 9/11 related subjects without every discussion being overshadowed by certain individuals.
Regrettably, prior to 9/11 no one would foresee a second impact in the South Tower. I've noted in the description that despite the complex being one large superblock, each building was independently controlled. There's a sound file somewhere that did indeed declare the situation in the North Tower under control and thus ordered all occupants to return to their offices. In hindsight, that automated notice was another fatal addition to the tragedy. Not only could the South Tower have been more empty, I recall it caused a massive holdup in the stairwells due to people moving in both directions.
Robville Virtual Realisations yes they said, " Building A or Building 1 is secure, please remain at your desks. I repeat: Building A is secure, remain at your desks." They only used the second fire alarm for about 4 minutes. I was at the lobby by the time the North Tower was on fire and the Port Authority stopped me from going home. I said "I'm going home, this is a danger can't you see that it's on fire?!" They made me change my mind and went back to my office on the 56th floor, then the plane crashes into the upper floors, now the second fire alarm kicked in again but it was different. A Port Authority officer said "GET OUT NOW!" I never saw him again but he saved my life. It wasn't the same officer who prevented me from leaving the Trade Center. Ever since that day, I didn't bother to return but now, I think I should visit the Trade Center gravesite and the gravesite of my fellow companions lost on that fateful day
JSD Jade 810 I also worked in Tower 2 on the 56th floor. My office was in the far north West corner. They told me that Building A was secure, but my brother told me that Building A was on fire. I received this at 9:01 AM. I was already at the main corridor ready to leave to go home. Two minutes later, everything around me rumbles, Building B is hit. I heard a low flying plane at the time. At first I thought it was a coincidence that both buildings exploded due to some sort of accident. They officially told us to evacuate when the South Tower was hit and by the time it was hit, I was already in the 23rd floor, when I reached the main lobby, I was running out and then this guy broke his leg trying to run down the stairs. I reached out and tried to help him, he said "My nephew... my nephew is up there." I asked where and he said "the 83rd floor." I was shocked to hear that and then he asked if the fire department can save his life and rush to the upper floors. We got out of the WTC complex and we kept on going until the Empire State Building. By the time the firefighters reached the 83rd floor and we reached the State Building, from there we watched the South Tower falling. He watched his nephew perish along with the others as the tower tell. He froze for two seconds and then started praying for him. 8 hours later, they found his remains....
Damn Damian that is very sad and depressing for the guy who lost his nephew. I'm just so glad we're alive from the mess that the Islamic animals hijacked commercial airliners and smashed them into our workplace, the Pentagon, and then innocent people on the last flight. I pray every month for those who perished on that fateful day. I wonder how I'm still alive and I say "It's a miracle, god still believes I made it out." I personally think that the new WTC is haunting and scary, I wouldnt want to work there. The Twin Towers are unreplaceable and I miss them, but at the same time if I see them again in person, PTSD kicks in and then I get scared thinking about it
The WTC 7 alarm was also in WTC 5. There’s a video of people evacuating through the building and the alarm is going off in the background. Edit: Turns out the audio was dubbed in that video, but you can hear the two chimes coming from one of the low-rise plaza buildings in Jack Taliercio’s footage.
Robville Virtual Realisations I forget the name of it. I saw it on TH-cam though. Search something along the lines of “evacuating through WTC 5” or something like that. I think that was what the video was called.
@@savagepanda8458 Found it: th-cam.com/video/gv-wANt35hw/w-d-xo.html Really interesting find there since none of the reports mention that Firecom was used elsewhere besides building 7. I think it is safe to assume the other lowrise buildings had the same system then. I appreciate the feedback.
Robville Virtual Realisations Also, I just noticed that in the well known footage taken by Jack Taliercio, you can hear the two chimes in the background, at one point.
As cleverly noted by user Datamaster, it turns out the Firecom alarm was added into that video in post. I've overlapped the audio with Mark LaGanga's WTC 7 footage and not only does the alarm sound overlap perfectly, I was able to distinguish other background noises from LaGanga's video that were present in the WTC 5 evacuation video as well, at the exact same time also. He had also pointed out that in between videocuts, the chime sound continues uninterrupted. If it was an actual recording that would coincidentally overlap between takes, there would be at least some form of an audio cut. And to think of it now, it actually makes sense that the audio was edited in later, because the chime sounds signaled a notification of the fire department. They would not be required in any of the lowrise buildings. Also, the reason WTC 7 had a Firecom system was because it was built much later than the main complex and Firecom was much newer around 87. The only upgrade the main complex got was until after the bombing of 1993. By that time, Firecom was outdated compared to the voice assisted MXL system, which was then intended to succeed the original Pyrotronics alarm. That explains why no reports ever mentioned anything otherwise. *Edit* I found the original video from Evan Fairbanks where the audio was added onto: th-cam.com/video/pz6_8WAIGb4/w-d-xo.html It seems that the original footage did not have any sound, which explains why there were effects added.
@@wvs-productions2937 These were mostly just pet projects out of an interest I have in the buildings. I may upload something random about the WTC every once in a long while. Feel free to share any ideas though. Like the alarm sounds, I love sharing things that people have been looking for.
@@RobvilleVirtualRealisations iv been trying to figure out which fire alarm columbine high school used its heard in 911 calls and seen in the fire departments crime scene video i was wondering if you could figure out what kind of alarm this is and maybe make a video on it
@@wvs-productions2937 Oh I see. Unfortunately I have no knowledge about the Columbine attack, and related subjects. My knowledge of fire alarms limits itself to the WTC complex.
@@RobvilleVirtualRealisations okay thank you btw my favorite alarm is firecom 8500 i believe i may have found a video where it was in the background it was a video where a guy was leaning against wtc 7 or around it and was filming the burning wtc 5 however the firecom 8500 you can hear the chime but instead of 5 chime it is continuing without stopping
Thank you for uploading. Very good, clean generated sounds of the Firecom 8500 tones, which have fascinated me for a while. There is one quite eerie video on TH-cam, might be unlisted, called "Inside 7 World Trade Center Moments Before Collapse", and you can hear the 8500 system chiming and whooping away throughout a good chunk of the video. Sounds are spot-on. Maybe just a difference in timing, like you mentioned in the description. I have wanted to recreate these sounds for some time to use in a possible simulation system setup, but I don't know what program I would use to do it, much less how to do it. Great job.
I appreciate it! The video you're referring to was shot by Mark LaGanga, which provided a rare account on the trade center site in between collapses of the south and north tower. From what I could gather from the Firecom patent, the alternation between the whoops and chimes was regulated through circuitry rather than being a fixed sound file. That might explain the varying duration of it as heard in LaGanga's video. You can even hear the whoops either being cutoff or starting midway a repetition.
I would like to point out that the video in the description being used as evidence for the alarm systems in 4, 5 and 6 *almost certainly* has dubbed audio. It sounds exactly like the audio from the video taken in WTC7. You can even hear the part where the camera man (camera man filming WTC7) is running up the escalator which doesn't match the video at all. you can even see a part of the video where the image skips but the audio of the alarm doesn't
@@DatamasterCorporation Interesting note there. The chime sound does indeed overlap a cut. I'll download the video with LaGanga's WTC 7 video to see if the alarms overlap perfectly. If so I'll remove that note. It could explain why it doesn't make sense that the complex was partially Cerberus and partially Firecom. WTC 7 used Firecom because it was built later and a bit of a standalone entity to the complex. The concourse however was there from the beginning so it would make sense the systems within would match. I appreciate the insight.
@@DatamasterCorporation It turns out you are right. Very well spotted! The sound from Mark LaGanga's video perfectly overlaps the one in the lowrise evacuation video. Aside of the alarm sounds matching perfectly, I was able to distinguish a ringing phone in the background which can be faintly heard in both videos at the exact same time as well. I'll remove the note, and thanks again for pointing that out. *Edit* I found the original video from Evan Fairbanks: th-cam.com/video/pz6_8WAIGb4/w-d-xo.html Turns out the original does not have any sound in it, hence why the uploader of the edited footage has added effects. Shame the uploader doesn't acknowledge this.
There's a video of a few men assisting a firefighter to make sure the building below the site of impact was evacuated (I want to say it was the South Tower) moments before it fell. You can hear the alarm that begins at 1:08 in the background.
You can watch Mark LaGanga's haunting 9/11 footage where he actually walked into the lobby of WTC 7 shortly after the first tower collapsed and had a chat with a Secret Service Agent in the ash-filled lobby while the Firecom 8500 was going off. Hope he got out of there okay.
Notice for previous commenters: Due to an odd TH-cam bug, a lot of comments on this video were removed without any notification. To those who commented; I did not delete your message, and really appreciate the response given to me. I was able to read them though in my bell notification before they disappeared. It frustrates me that I wasn't able to reply to you all. It now seems that the bug has gone, so I've reopened the comments section. Fingers crossed. So, anyone, feel free to add any comments or ask any questions.
@@DylanKevilleSirens Unfortunately I wasn't able to find any documentation about it. Considering the rest of the superblock used a Cerberus system, it is somewhat likely it was incorporated in there as well. But again, there's no certainty of it due to the lack of documentation.
It most likely was a Cerberus system, as the rest of the WTC hat it other than WTC 7, which was completed later on, and is probably why the system was different, I still find the whoop/ chime tone very weird
1:12 I’ve seen a video of somebody evacuating people from building 7 I think after the north tower collapse, this alarm was playing in the background and was echoing through the whole structure, proof that hero’s don’t always wear capes.
Thank you youtube algorithm, recomending me the last sounds that many heard in a horrible incident, that is exactly what I needed to end my afternoon :)
We are hearing a piece of history right here! Interesting to see someone has preserved how the fire alarms in the WTC would have sounded like. We are hearing what the victims stuck in the towers would have heard possibly in their last moments...
In many videos of the attacks you can hear the alarms going off especially the video footage of someone going into 7 WTC and encountering the Secret Service Agent.
Rest in peace to those who died My respect goes out to them So sorry to their loved ones Thank you to police officers, firefighters, those who tried to help another life, doctors, nurses 🕊🤍
The original WTC 7 was a very mysterious building... So much in fact that you likely won't find any interior pictures or footage of it prior to the 9/11 incidents, & only a glimpse of it during the tragedies. Such a shame.
This video may well be short, but must trigger so many people in so many different ways. I hope if you were there and found the courage to listen to this, you're moving on and trying to live the best way you can. If not, try and do a little thing for you today. Take care.
00:05 To 01:08 The Alarm in the picture is a Wheelock 34-24, it's not a speaker it's a mechanical horn 01:09 To 01:42 The Alarm in the picture on the left is a Roshni Sounder, it's not a speaker it's a sounder. The Alarm in the picture on the right is a Simplex 4051 with 4050-80 light plate, it's not a chime it's a mechanical horn
Thanks for the clarification! Goes to show that I had a misunderstanding of the equipment that was described. Curious, do you know what the speaker systems should've looked like? The Wheelock 34-24 I had mistakenly assumed to be the speaker based on the Port Authority WTC evacuation video. It starts by showing the alarm whilst playing the Cerberus whoops. I did not know at the time of making this video that it was an artistic choice that I assumed to be factual.
@@RobvilleVirtualRealisations Hi again, I have seen a few discussions on the speaker strobes that WTC 7 had. it appears that they used modified Wheelock speaker strobes, similar to the E70-2430W. However, either the strobes were disabled, the lobby speakers did not have them, or the camera just didn't pick up the strobes in the video that shows WTC 7 after the south tower collapse. Either way Firecom seemed/seems to like Wheelock speaker strobes (if the assertion of what WTC 7 had is correct) because the new World Trade Center mall also uses Wheelock speaker strobes and was installed by Firecom.
I've heard a couple of these before in a video in the tower on 9/11. I wasn't born yet so it's very interesting to me and I've seen a lot of on-ground footage. Scary shit.
More info on the alarms in 1-5: They used MXL-V Slow whoop un-voice assisted. The speakers were Cerberus Pyrotronics SS25-15/75 Wall speaker strobes, With the pull stations most likely being Cerberus pyrotronics MS-MIs.
the first alarm is the one that haunts me the most, if you watch the full jules naudet tape it's constantly in the background from when the firefighters first arrive to when the south tower falls
I think all fire alarms should be voice assisted , I think it gives a clearer message to indicate a real emergency. These alarms are always so haunting to hear especially knowing where and when they were used. Take a moment of silence for those lost.
I saw a video that was like five minutes before the seven building collapsed and they’re saving people and that fire alarm was still blaring that chime kind of sounds like the back rooms
1:28 I remember hearing that exact sound in a dream where I was in Level “The Metro” in the Backrooms. I remember 2 new files on my phone’s “Files” app appeared in On My iPhone without a file extension and no spaces just snake case and the wiki said that deleting one of them would cause you to get thrown out of the train and into a void and I forgot what deleting the other one did but it was bad. But I heard that exact sound when the Metro stopped at a stop, that sound played in the metro train while it docked to open the doors, while it was totally empty both the train and station. Never saw a single entity or human.
i saw a picture of the firecom test station and one of the boards had some alarms that looked the same and there was a paper that said WTC 7 the alarm looks similar to the wheelock e-70 2475w
I watched a video of inside WTC 7 on 9/11 and it had this exact alarm. I also listened to NYFD recordings inside the twin towers that day and I could hear the fire alarms as well.
Any time i try to add a link the video gets remover It used the old version, you can hear it in this video here at 27:0228:30 (you hear it the loudest at 8:00 - & 43:57 & 45:00 VERY Faintly the video is called "First Response (Full Episode) | 9/11" and this video called "9/11 FDNY RADIO WTC 2 COLLAPSE" at 0:23 & 0:45
You can hear the fire alarm quite clearly in this video at 16:10 mark: th-cam.com/video/_KA5ifs4kD4/w-d-xo.html In fact, you can hear the faint south tower fire alarm going off as well.
Theres video insideoc wtc right before it collapsed and all you hear is people fleeing and The firecom 8500.Thats gives me goosebumps.Imagine trapped and all you hear is spine chilling alarms.
Building three actually had an Edwards system, this was because building 3 was a Marriott hotel, and was not actually part of the wtc complex, but was destroyed by falling debris anyway
That has to be the most chilling thing I’ve listened to. And to know this what people heard while watching and waiting in fear and terror, praying and hoping for whatever end was coming. It almost gives you the same sense of horror.
these massive buildings are so cool. they’re like a modern car with a bunch of different sounds and chimes and everything is controlled by some “machine room” with electrical components and ecus/computers and stuff like that.
The complex truly was a city within a city. I don't recall that there has ever been a building with more floor space than this. Both before and after 9/11.
Since I’ve been in two hotels with old Firecom systems, I wanna say the speakers in WTC 7 were made by Atlas Soundolier if they weren’t Wheelock or CP.
That's really interesting to know. I couldn't find any information at all about what kind of speakers there were used, so the images included were to my best of estimations. I'll add it as a note. Do you by any chance have some sort of reference that I can take a look at?
I don’t, unfortunately. I just know that the Stuart and Affinia Dumont hotels have Firecom systems with Atlas Soundolier speakers. It’s a stretch, and I could be very wrong, but that’s what I think WTC 7 had. Look up “Atlas Soundolier SVT-72”.
@@ticearpey3235 I really appreciate the feedback regardless. Your estimation seems a lot more plausible than mine, especially since you've seen it firsthand, and the speaker you've listed seems well capable of the frequency that Firecom used. I've noted it down in the video description as a possible inaccuracy of the video.
I also appreciate you taking the feedback! With the little info provided, and those two hotels, I only assume this is what the majority of Firecom 8500 or similar systems were like in NYC. Never forget.
Building 7 Used Wheelock ET-1010's and Wheelock E70's. Commonly Firecom 8500 Voice Evacuation Panels During that time era used Wheelock ET Speakers and Speaker/Strobes, And Sometimes Simplex. I was at a Hotel(I forgot where), And Thie sound at 1:20 Was the exact Whoop From the Firecom 8500 Voice series. So The Master Control Panel was in a Special Big Walk In Closet. If the mics were keyed, You'd hear the Chime tone,(Some systems played The Chime tone
So building 7 had a system that would make a chime sound whenever the fire department arrived. Does the fire department click something in order to enable that sound?
I think how it worked was that the whoop simply meant evacuation, and that the chime was played once the fire dept had succesfully been notified. This likely would've gone automatically just as large buildings automatically notify the fire department today.
There is a video on TH-cam from inside one of the twin towers before 9/11 and you can see some of the alarm devices throughout the video. Link th-cam.com/video/LPCvby-M-GY/w-d-xo.html Also the alarm at 0:24 you can hear in footage taken from inside one of the twin towers lobby. You can hear the slow whoop of the alarms throughout the video. Along with the alarms doing the "Ping" sound once or twice.
Building 7’s alarm is bone chilling and nostalgic at the same time. Given that I was born after 9/11 I wonder if it’s standard in the city and I heard it from there?
*Any comments hinting towards any conspiracy theories will be removed.*
Yeah, those comments arguing about how the towers collapsed because of explosives are just annoying because we know that is not true.

I find WTC 7’s alarm more haunting than the others (in my opinion)
Same, but that's point of FireCom 8500. You get scared so hard that you run out of building as fastest you can.
same especally in the real life videos... what kinda scares me is the sound of those scba alarms going off all over the place
It is
@im batman They didn't. FireCom 8500 didn't even exist at time when Twin Towers were made.
Yes
The voice on the first alarm is chilling: “A fire emergency has been reported in the building.” Given that the buildings were hit by 767s and roughly 10 floors were on fire, that’s an understatement. It’s crazy to think that some people towards the bottom didn’t feel the jet impacts and the electricity, water, telecom, etc., continued to function. That’s how huge those buildings were.
The floors under impact still had electric and water
I bet they felt the explosion in the basement prior to the first plane crash though
It's pre recorded
I’m pretty sure if a Boeing 767 slammed into your building you’d feel it no matter where you were
This is the second one and first one 0:31
WTC 7 alarm is so eerie. Hearing it makes me so sad and hollow. I can’t imagine…the fear, the pain, and sadness they all felt.
Same i Hate the sound it's so scary
At least everyone in WTC 7 was evacuated.
I think the chime mode sounds the most eerie cus it's just to
You probably heard it on the news. They did a check of the building before it collapsed and you could hear it.
No one died in WTC 7, it was evacuated
The building 7 alarm can be heard in several videos from before the collapse in towers one and two.

In the longer version of Melissa Doi's phone call to 911 there are moments in which you can hear the fire alarm in the background. So glad the dispatcher stayed on the phone with her to the end.
I came here after hearing the WTC7 alarm in some documentary footage taken shortly before it collapsed. That sound is... creepy, unsettling, haunting. The part with two beeps is the creepiest part for me, for some reason, but the whole thing fills your soul with dread.. I've never heard an alarm like that before. Nor have I ever felt compelled to look up an alarm sound until this one.
I think thats on purpose. Sure everyone knows thats on purpose, but let me explain further: i think the one who designed the sound, knew, that New York is filled with a lot of sounds, noises, beeps, etc.. So he had the hard task to design a alarm, which not only distinguish itself by every other possible sound in New York, but also sounds so much serious and horrifying, that everyone in that building would take it serious immediately. The sound sounds so easily designed, but it isnt. Not only the pitch is very well choosed, not to low, not to high (its in the sweet spot of the highest sensitivity of the human ear . The ear is less sensitive for higher notes, as well as for low notes). The 'attack'' (first 100 ms of the sound) is also very well choosed, which makes this ''hammering'' noice in the beginning of the beep. It literally alarms the body , because of that hammering uneasy feel. The sound designer also choosed a sawtooth-waveform, which in a subtile way differs from a piano-note. Also the rhythm of that noise is in the pattern of a heartbeat, with a long release-phase (like an echo or reverb of the noise).
Everything of that sound is made to take actions, way before people smell smoke, or see fire. Its really very intelligent psychological sound design. Thats why in the comment section a lot of people point out that sound, and describe it as creepy , eerie, etc.
wait a plane hit WTC7?
@@fortcraft_snv No it didnt. But WTC7 collapsed anyway, due to the damage made by the collapsing two twintowers, and hours of fire in the building.
@@fortcraft_snv no, but flying debris has a tendency to set shit on fire
@@PygmalionFaciebatThat is a very good assessment of this alarm. I also was thinking something very similar to what you were saying about how it seems simple, but someone probably put a lot of thought into its sound, and did so intentionally to better establish a sense of urgency when it sounds. This is probably the one alarm people would hear and actually think twice about it (except for just finding the alarm annoying). I've seen typical alarms going off in public places like malls and even airports and they just are ignored. It's so a-typical of an alarm you'd never forget it. Also notice how it's not ear shattering loud like almost every alarm, the two people are able to have a conversation without the alarm over stepping them. Quite a fascinating thing, but I could also just be overthinking it. Would be interesting to hear from the people who designed it where the idea came from.
I can hear that ping sound at 1:30 in a lot of documentaries and I had no idea it was only for building 7. I thought it was coming from building 1 or maybe 2
its sad that this is the last sound people heard before dying

WTC7 is literal hell
@AA The chime sound was there to notify about a fire related incident whereas the whoop signaled evacuation. Firecom still provides the alarm system for the current WTC complex, and there's a video in which someone films the alarm going off within the transportation hub. Albeit a slightly different tone due to it of course being a newer variant, Firecom still utilizes it.
There were no alarms associated with the destruction of buildings as such since not only because such scenario's are too specific, it would also defeat the purpose of what an alarm is for; to notify about ongoing hazards within the confinement of the building itself.
WTC 7's alarm got triggered after the collapse of the South Tower, presumably due to the vast amount of smoke entering the building.
Lastly, the chime sound can be heard within Mark LaGanga's video of WTC7's lobby. The North Tower was still standing at that point.
Robville Virtual Realisations
what is the video called that features the Transportation hub alarms?
@@DylanKevilleSirens The video title is "Fire Alarm Activation at One World Trade Center in NYC" (no quotations). You'll hear a triple chime repetition with voice assistance.
@@RobvilleVirtualRealisations What processor did Firecom use to generate those tones, and what was the name of the guy who wrote the software?
I have a feeling that the Staples Center in LA has that whoop, being that the system there is a Firecom.
Kinda bizarre that you were able to find this. I never thought I'd EVER hear the isolated alarm sound from building 7. In general there's not a lot of photographs or info pertaining to 7 in general
It’s so eerie how they’re all just in that building running around screaming and jumping out the windows and that noise continuously plays
absolutely terrifying
i can't even imagine the sheer terror and despair those people must've felt
Im glad tbh, beeping's far less scarier
my mom was working in an airport the day that this happened. She wasn’t scared, but my dad and sister were pretty worried. I wasn’t born when this happened, so it’s interesting to see stuff like this and other videos and what actually happened. Easily some of the most terrifying things I’ve ever watched on TH-cam.
Dude, you have the same thoughts as me pretty much haha. I wasn't born in 2001 either, my parents always told me what it was like on the day of the attack in the USA, here in Brazil. Here in Brazil, my completely desperate grandmother picked up my mother from school, thinking that this could happen here in Brazil. My father still lived on a farm, he was in a local business watching on a small television, all the news being interrupted to give the news that a plane had collided in WTC 1. Soon after, my father reported that he saw the second aircraft hit the other tower. And so it was for the rest of the day, following everything about 9/11 in 2001 on that commercial television my father was on... It must have been something shocking to have followed that. I'm very excited about all this, it gives me something inside me, I've always been one to research and find out more about 9/11. We can say that since 2001 until today I have been very interested in looking for everything about this regrettable event. Whenever possible, I always watch videos, read articles from the USA and Brazil about the event, I go very in-depth about it, and I always look on the internet for possible things that remain from 9/11 today. This interests me a lot. Hugs here from Brazil💪🏻
I was 6 years old at the time of this incident.
That nice 70s or 80s styled fire alarms. I love it.
I've been going through the comments and its surprising how clean you've kept them, that and you know a lot more about alarm systems than I do. Good job
Thanks! Doing my best to keep the place tidy for those who want to learn about and discuss the subject. I've learned quite a bit form the people in the comments here and even noted some inaccuracies based on their input. There aren't that many places where enthusiasts can discuss 9/11 related subjects without every discussion being overshadowed by certain individuals.
1:09 i will never forget that alarm
Same
So sad 😭😢
I perfectly recognised wtc 7 alert. Haunting one
THEY DIDNT TELL US TO EVACUATE, THEY TOLD US REMAIN AT OUR DESK. In the South Tower
Regrettably, prior to 9/11 no one would foresee a second impact in the South Tower. I've noted in the description that despite the complex being one large superblock, each building was independently controlled. There's a sound file somewhere that did indeed declare the situation in the North Tower under control and thus ordered all occupants to return to their offices. In hindsight, that automated notice was another fatal addition to the tragedy. Not only could the South Tower have been more empty, I recall it caused a massive holdup in the stairwells due to people moving in both directions.
Robville Virtual Realisations yes they said, " Building A or Building 1 is secure, please remain at your desks. I repeat: Building A is secure, remain at your desks." They only used the second fire alarm for about 4 minutes. I was at the lobby by the time the North Tower was on fire and the Port Authority stopped me from going home. I said "I'm going home, this is a danger can't you see that it's on fire?!" They made me change my mind and went back to my office on the 56th floor, then the plane crashes into the upper floors, now the second fire alarm kicked in again but it was different. A Port Authority officer said "GET OUT NOW!" I never saw him again but he saved my life. It wasn't the same officer who prevented me from leaving the Trade Center. Ever since that day, I didn't bother to return but now, I think I should visit the Trade Center gravesite and the gravesite of my fellow companions lost on that fateful day
@@mr.levintouge154 I'm glad you made it out alive. Thank you for sharing your story about that fateful day
JSD Jade 810 I also worked in Tower 2 on the 56th floor. My office was in the far north West corner. They told me that Building A was secure, but my brother told me that Building A was on fire. I received this at 9:01 AM. I was already at the main corridor ready to leave to go home. Two minutes later, everything around me rumbles, Building B is hit. I heard a low flying plane at the time. At first I thought it was a coincidence that both buildings exploded due to some sort of accident. They officially told us to evacuate when the South Tower was hit and by the time it was hit, I was already in the 23rd floor, when I reached the main lobby, I was running out and then this guy broke his leg trying to run down the stairs. I reached out and tried to help him, he said "My nephew... my nephew is up there." I asked where and he said "the 83rd floor." I was shocked to hear that and then he asked if the fire department can save his life and rush to the upper floors. We got out of the WTC complex and we kept on going until the Empire State Building. By the time the firefighters reached the 83rd floor and we reached the State Building, from there we watched the South Tower falling. He watched his nephew perish along with the others as the tower tell. He froze for two seconds and then started praying for him. 8 hours later, they found his remains....
Damn Damian that is very sad and depressing for the guy who lost his nephew. I'm just so glad we're alive from the mess that the Islamic animals hijacked commercial airliners and smashed them into our workplace, the Pentagon, and then innocent people on the last flight. I pray every month for those who perished on that fateful day. I wonder how I'm still alive and I say "It's a miracle, god still believes I made it out." I personally think that the new WTC is haunting and scary, I wouldnt want to work there. The Twin Towers are unreplaceable and I miss them, but at the same time if I see them again in person, PTSD kicks in and then I get scared thinking about it
The WTC 7 alarm was also in WTC 5. There’s a video of people evacuating through the building and the alarm is going off in the background.
Edit: Turns out the audio was dubbed in that video, but you can hear the two chimes coming from one of the low-rise plaza buildings in Jack Taliercio’s footage.
Do you have a link to that video?
Robville Virtual Realisations I forget the name of it. I saw it on TH-cam though. Search something along the lines of “evacuating through WTC 5” or something like that. I think that was what the video was called.
@@savagepanda8458 Found it: th-cam.com/video/gv-wANt35hw/w-d-xo.html
Really interesting find there since none of the reports mention that Firecom was used elsewhere besides building 7. I think it is safe to assume the other lowrise buildings had the same system then. I appreciate the feedback.
Robville Virtual Realisations Also, I just noticed that in the well known footage taken by Jack Taliercio, you can hear the two chimes in the background, at one point.
As cleverly noted by user Datamaster, it turns out the Firecom alarm was added into that video in post. I've overlapped the audio with Mark LaGanga's WTC 7 footage and not only does the alarm sound overlap perfectly, I was able to distinguish other background noises from LaGanga's video that were present in the WTC 5 evacuation video as well, at the exact same time also. He had also pointed out that in between videocuts, the chime sound continues uninterrupted. If it was an actual recording that would coincidentally overlap between takes, there would be at least some form of an audio cut.
And to think of it now, it actually makes sense that the audio was edited in later, because the chime sounds signaled a notification of the fire department. They would not be required in any of the lowrise buildings. Also, the reason WTC 7 had a Firecom system was because it was built much later than the main complex and Firecom was much newer around 87. The only upgrade the main complex got was until after the bombing of 1993. By that time, Firecom was outdated compared to the voice assisted MXL system, which was then intended to succeed the original Pyrotronics alarm. That explains why no reports ever mentioned anything otherwise.
*Edit*
I found the original video from Evan Fairbanks where the audio was added onto: th-cam.com/video/pz6_8WAIGb4/w-d-xo.html It seems that the original footage did not have any sound, which explains why there were effects added.

Timestamp 1:09: That is ONE scary alarm. It sends chills down my spine envisioning that alarm in the Twin Towers, even though it wasn’t actually used.
Thank you for uploading. Very good, clean generated sounds of the Firecom 8500 tones, which have fascinated me for a while. There is one quite eerie video on TH-cam, might be unlisted, called "Inside 7 World Trade Center Moments Before Collapse", and you can hear the 8500 system chiming and whooping away throughout a good chunk of the video. Sounds are spot-on. Maybe just a difference in timing, like you mentioned in the description. I have wanted to recreate these sounds for some time to use in a possible simulation system setup, but I don't know what program I would use to do it, much less how to do it. Great job.
I appreciate it! The video you're referring to was shot by Mark LaGanga, which provided a rare account on the trade center site in between collapses of the south and north tower.
From what I could gather from the Firecom patent, the alternation between the whoops and chimes was regulated through circuitry rather than being a fixed sound file. That might explain the varying duration of it as heard in LaGanga's video. You can even hear the whoops either being cutoff or starting midway a repetition.
@@RobvilleVirtualRealisations Ah, okay. Thanks for the information! You can definitely hear it was a very primitive system, and a fascinating one.

I would like to point out that the video in the description being used as evidence for the alarm systems in 4, 5 and 6 *almost certainly* has dubbed audio. It sounds exactly like the audio from the video taken in WTC7. You can even hear the part where the camera man (camera man filming WTC7) is running up the escalator which doesn't match the video at all. you can even see a part of the video where the image skips but the audio of the alarm doesn't
@@DatamasterCorporation Interesting note there. The chime sound does indeed overlap a cut. I'll download the video with LaGanga's WTC 7 video to see if the alarms overlap perfectly. If so I'll remove that note.
It could explain why it doesn't make sense that the complex was partially Cerberus and partially Firecom. WTC 7 used Firecom because it was built later and a bit of a standalone entity to the complex. The concourse however was there from the beginning so it would make sense the systems within would match.
I appreciate the insight.
@@DatamasterCorporation It turns out you are right. Very well spotted!
The sound from Mark LaGanga's video perfectly overlaps the one in the lowrise evacuation video. Aside of the alarm sounds matching perfectly, I was able to distinguish a ringing phone in the background which can be faintly heard in both videos at the exact same time as well. I'll remove the note, and thanks again for pointing that out.
*Edit*
I found the original video from Evan Fairbanks: th-cam.com/video/pz6_8WAIGb4/w-d-xo.html
Turns out the original does not have any sound in it, hence why the uploader of the edited footage has added effects. Shame the uploader doesn't acknowledge this.
This honestly makes me depressed because people didn’t have a chance to survive the explosion and fires.
Will return on the 11 to pay respects.
There's a video of a few men assisting a firefighter to make sure the building below the site of impact was evacuated (I want to say it was the South Tower) moments before it fell. You can hear the alarm that begins at 1:08 in the background.
WTC7's alarm sounds like something straight out of a sci-fi horror movie!
You can watch Mark LaGanga's haunting 9/11 footage where he actually walked into the lobby of WTC 7 shortly after the first tower collapsed and had a chat with a Secret Service Agent in the ash-filled lobby while the Firecom 8500 was going off. Hope he got out of there okay.
It's some really striking footage and truly a rare encounter. Thankfully, both LaGanga and the agent made it out safely.
The first fire alarm is actually standard across Australia.
Notice for previous commenters:
Due to an odd TH-cam bug, a lot of comments on this video were removed without any notification. To those who commented; I did not delete your message, and really appreciate the response given to me.

What did building 3 have?
@@DylanKevilleSirens Unfortunately I wasn't able to find any documentation about it. Considering the rest of the superblock used a Cerberus system, it is somewhat likely it was incorporated in there as well. But again, there's no certainty of it due to the lack of documentation.
It most likely was a Cerberus system, as the rest of the WTC hat it other than WTC 7, which was completed later on, and is probably why the system was different, I still find the whoop/ chime tone very weird
What did Building 7 have
1:12 I’ve seen a video of somebody evacuating people from building 7 I think after the north tower collapse, this alarm was playing in the background and was echoing through the whole structure, proof that hero’s don’t always wear capes.

Thank you youtube algorithm, recomending me the last sounds that many heard in a horrible incident, that is exactly what I needed to end my afternoon :)
1:09 is haunting i remember seeing it in documentaries on the attacks
We are hearing a piece of history right here! Interesting to see someone has preserved how the fire alarms in the WTC would have sounded like. We are hearing what the victims stuck in the towers would have heard possibly in their last moments...
In many videos of the attacks you can hear the alarms going off especially the video footage of someone going into 7 WTC and encountering the Secret Service Agent.
Rest in peace to those who died
My respect goes out to them
So sorry to their loved ones
Thank you to police officers, firefighters, those who tried to help another life, doctors, nurses 🕊🤍
The original WTC 7 was a very mysterious building... So much in fact that you likely won't find any interior pictures or footage of it prior to the 9/11 incidents, & only a glimpse of it during the tragedies. Such a shame.
some floors of original WTC 7 and all of WTC 6 were rented by government agencies which may explain why not much was recorded there at the time.
This video may well be short, but must trigger so many people in so many different ways.
I hope if you were there and found the courage to listen to this, you're moving on and trying to live the best way you can. If not, try and do a little thing for you today.
Take care.
00:05 To 01:08 The Alarm in the picture is a Wheelock 34-24, it's not a speaker it's a mechanical horn
01:09 To 01:42 The Alarm in the picture on the left is a Roshni Sounder, it's not a speaker it's a sounder. The Alarm in the picture on the right is a Simplex 4051 with 4050-80 light plate, it's not a chime it's a mechanical horn
Thanks for the clarification! Goes to show that I had a misunderstanding of the equipment that was described. Curious, do you know what the speaker systems should've looked like?
The Wheelock 34-24 I had mistakenly assumed to be the speaker based on the Port Authority WTC evacuation video. It starts by showing the alarm whilst playing the Cerberus whoops. I did not know at the time of making this video that it was an artistic choice that I assumed to be factual.
@@RobvilleVirtualRealisations
Hi again,
I have seen a few discussions on the speaker strobes that WTC 7 had. it appears that they used modified Wheelock speaker strobes, similar to the E70-2430W. However, either the strobes were disabled, the lobby speakers did not have them, or the camera just didn't pick up the strobes in the video that shows WTC 7 after the south tower collapse. Either way Firecom seemed/seems to like Wheelock speaker strobes (if the assertion of what WTC 7 had is correct) because the new World Trade Center mall also uses Wheelock speaker strobes and was installed by Firecom.
bro mastered the alarms
@@DatamasterCorporationThey used the loud PA Speakers and Atlas speakers too
It's not Roshni. I looked online, and fire sirens like the one on the left seem to be a red Apollo ESI-40 or ESI-50 fire siren.
I've heard a couple of these before in a video in the tower on 9/11. I wasn't born yet so it's very interesting to me and I've seen a lot of on-ground footage. Scary shit.
More info on the alarms in 1-5: They used MXL-V Slow whoop un-voice assisted. The speakers were Cerberus Pyrotronics SS25-15/75 Wall speaker strobes, With the pull stations most likely being Cerberus pyrotronics MS-MIs.
this hits differently when you remember what happened there
Got nothing on the alarms at Black Mesa.
the first alarm is the one that haunts me the most, if you watch the full jules naudet tape it's constantly in the background from when the firefighters first arrive to when the south tower falls
I think all fire alarms should be voice assisted , I think it gives a clearer message to indicate a real emergency. These alarms are always so haunting to hear especially knowing where and when they were used. Take a moment of silence for those lost.
Sound at 1:20 should still be used today in fire alarm systems cause it generates fear instantly making you want to get out immediately.
This series of Firecom has been discontinued since like the early-mid 90s.

I remember 2 new files on my phone’s “Files” app appeared in On My iPhone without a file extension and no spaces just snake case and the wiki said that deleting one of them would cause you to get thrown out of the train and into a void and I forgot what deleting the other one did but it was bad. But I heard that exact sound when the Metro stopped at a stop, that sound played in the metro train while it docked to open the doors, while it was totally empty both the train and station. Never saw a single entity or human.

Since I’ve been in two hotels with old Firecom systems, I wanna say the speakers in WTC 7 were made by Atlas Soundolier if they weren’t Wheelock or CP.
That's really interesting to know. I couldn't find any information at all about what kind of speakers there were used, so the images included were to my best of estimations. I'll add it as a note.
Do you by any chance have some sort of reference that I can take a look at?
I don’t, unfortunately. I just know that the Stuart and Affinia Dumont hotels have Firecom systems with Atlas Soundolier speakers. It’s a stretch, and I could be very wrong, but that’s what I think WTC 7 had. Look up “Atlas Soundolier SVT-72”.
@@ticearpey3235 I really appreciate the feedback regardless. Your estimation seems a lot more plausible than mine, especially since you've seen it firsthand, and the speaker you've listed seems well capable of the frequency that Firecom used.

I also appreciate you taking the feedback! With the little info provided, and those two hotels, I only assume this is what the majority of Firecom 8500 or similar systems were like in NYC.
Never forget.
Building 7 Used Wheelock ET-1010's and Wheelock E70's. Commonly Firecom 8500 Voice Evacuation Panels During that time era used Wheelock ET Speakers and Speaker/Strobes, And Sometimes Simplex. I was at a Hotel(I forgot where), And Thie sound at 1:20 Was the exact Whoop From the Firecom 8500 Voice series. So The Master Control Panel was in a Special Big Walk In Closet. If the mics were keyed, You'd hear the Chime tone,(Some systems played The Chime tone
The fire alarms are haunting. WTC7 is the most horrifying... I heard it today in my building during an alarm test.
Building 7’s sounds like the end of the world.
Building 7’s alarm has always stuck with me
You can hear building 7's alarm on Mark LaGanga's 9/11 video.
When he walks around the lobby of building 7 before the collapse
Link?
my college used the same PA system as WTC 1-6, so it was surreal hearing it at 8AM knowing that thats what people heard before they died.
All of these are very very terrifying. I would actually be terrified.
So building 7 had a system that would make a chime sound whenever the fire department arrived. Does the fire department click something in order to enable that sound?
I think how it worked was that the whoop simply meant evacuation, and that the chime was played once the fire dept had succesfully been notified. This likely would've gone automatically just as large buildings automatically notify the fire department today.
Gonna shit my pants if i keep watching these💀
Creepy that the captions say “applause” when the 2001 alarm plays. (For buildings 1,2,4,5,6, and 7
1:12 Oh wow😳
The amount of PTSD this video will give thousands of people
😩🥺 Haunting when these alarms were surely going off while everyone try escaping…
ive been looking for a cleaned up version of the wtc 7 alarm for years
0:17 Imagine this but your at the top floors.
They had no electricity up there. So they never heard this.
Message of "do not use elevators" on a freaking 100 floor is one of the most scariest thing to hear
Where can I download the WTC7 Firecom 8500 audio?
I just converted the Firecom 8500 part of the video to FLAC.
Even though I am now a Fire Alarm Enthusiast these Tones Scare Me.
There is a video on TH-cam from inside one of the twin towers before 9/11 and you can see some of the alarm devices throughout the video. Link th-cam.com/video/LPCvby-M-GY/w-d-xo.html
Also the alarm at 0:24 you can hear in footage taken from inside one of the twin towers lobby. You can hear the slow whoop of the alarms throughout the video. Along with the alarms doing the "Ping" sound once or twice.
Building 7’s alarm is bone chilling and nostalgic at the same time. Given that I was born after 9/11 I wonder if it’s standard in the city and I heard it from there?
