Fun little fact, the first siren to use alternate sounding was the Ferderal Signal Thunderbolt 1003. In production from 1961-1990, the 1003 used solenoids to alternate the sounding by opining on opposite timing or pulsing by opening in sync. The 1003 could do steady, alternate steady, pulse steady, wail, alternate wail, and pulse wail. Feel free to correct me in the comments! Also well done on the 100K!

Just sent him a British fire sounder so I can’t wait to see that on the channel

On behalf of the siren community, thank you for not calling it the "siren head" tone.

Some things I want to point out in this video 1. Many emergency sirens like for emergency vehicles or civil defense use a frequency sweep/modulated sound so that way it's distinctive over any other sounds in the environment that have a steady frequency that's not for an emergency like a truck back up beeper and the reason why it's not at the same pitch as a fire alarm is because it's it's avoid being a noise maker to a large population that's used for many emergencies and with the same thing for voice evac fire alarm systems but different as the tone they make is a low pitched 1 Khz tone but to be distinctive over other sounds it has to sound in temporal 3 where's a ear-piercing noise maker alarm for a small population yet still public mode like a burglar alarm is ear-piercing in order to involve fast reactions to the alarm like if a burglar alarm goes off the their will run away but if it's a large population emergency alarm then it's not ear-piercing to that way when people are taking action like hearing civil defense sirens during a tornado warning then it's to make sure there aren't any fast or weird reactions to people that can fail if they're high pitched which is why they're low pitched to eliminate the annoyance to large populations 2. The frequency sweep rate on many alarms is also different from one's that are lower in order to make sure they don't sound like a personal alarm device or something like that of it sounding like that as many fire alarms have a frequency sweep around 40-60 Hz to sound distinctive and warbling on the ears 3. It is very nice that on the LED EST Genesis Speaker Strobes allow you to change the Watts in real time while it's going off so that way you can quickly meet the noise level requirements on the alarm depending on it's space like a large room gets 2 Watts and a small room gets 1/4 Watts to be 15 dB higher than the ambient noise level if it's above 60 dB but if it's rarely below 60 dB then the alarms have to be 75 dB

fun fact, in Switzerland we had been extremly serious about which alarms and sirens do we use, but even more important, they are all the same all over Switzerland: 1 population alarm siren autorized 1 evacuation siren autorized 1 emergency vehicles's siren autorized (to be more precise, it's 2 volumes (campagne/highway and city/town), 2 tons (1 high, 1 low and they have to alternate at 1 speed), but different system are autorized (usually pneumatic and electronic)) 1 AMOK siren autorized (AMOK=american high school situation protocol (to be more serious, amok is a french word coming from malaisian and meaning something like "sudden and indiscriminate murderous behavior")) and there is a lot more, but basically, warning noise and siren are the same all over Switzerland and that's probably the most important.

MY HEADPHONES!

man you're gonna turn me into a tornado siren junkie lol that wail is so haunting, but super cool

the wheellock RSSA-24MCW with that blue strobe is my favorite strobe only alarm. also congrats on 100k🥳🥳🥳🥳🥳🥳

That sounds absolutely amazing, I sure do love those Federal Signal sirens on that tone and it’s interesting to hear it on a fire alarm sounder. Amazing video mate! 🔊🔥

They used alternate wail in my area near Albany, NY back in the early 80's. As a small child it would wake me at night and upset me to the point off tears. It works.

101K subs, congratulations! 👏👏

Congratulations to reaching 100K subscribers!

Just installed a visiplex system at work. The bullhorn speakers are quite loud. Couldn't find a proper tornado siren audio file so I installed an air raid siren.. definitely gets the job done.

I don't know why but this channel came back 🥰🥰 it was always my childhood

I like how you used the iconic Chicago siren

That sounds so pleasant

I am a weather nerd and hope to be a future meteorologist one day! I also love sirens to! Alternate wail is really cool too! Keep up the great work S.E.R. Safety!

i 100% agree with your those 2 sounds are very good at there job

I love this channel

Great video, Grant!

Congrats on 100k!

Great Video, Enjoyed It.

Awesome! 😊

Very cool! My personal favorite signal is attack

Very interesting test!

Hi! this video was awesome!

This is awsome

I love watching his videos they are so entertaining and fun to watch great videos SER safety and great job on 100k subs

this is a great idea i think schools should have these

I never thought that fire alarms were such good speakers😂😊

Wow that cool Sounding

S. E. R. Safety I’m a huge fan of you and of course fire alarms

The alternate wale can be played on thunderbolt 1003 and the speaker sirens as well

I had no idea you could do alternate wail on a fire alarm! Like imagine your in school, then you hear this

This video is awesome

Congrats on 100K subscribers! You should look into buying one of System Sensor's new LED devices. They're pretty cool!

They should have more of those tornado alarm switches in schools and buildings, then have that sound an actual tornado siren.

congrats in hitting 100k subscribers🥳🥳

There is tons of engineering that goes into fire alarms to make scary sounds. A key way is binaural tones or fast pulsating sounds, engineers typically choose a tone in the high pitched zone because it is more likely to scare someone to get attention. Slow down any fire alarm sound from the u.s and you will see that in some way it is changing pitch like a siren or simply pulsating. And how fire alarms are so loud and still using less than 5 watts is amazing. This is why I like fire alarms!

i like how they used the ewos 612 siren, cool!

I think the traditional "attack/wail" siren tone especially from an old school mechanical air raid siren is the spookiest.

Did you know a Whelen Vortex actually ran this signal? It was a finback in Hoover AL

My 8 year old is obsessed with your collection is your website up yet?

Letsss go congrats for 100k!

Congrats on 100k

hi, here are two suggestions : first, i know you have a MS-190 siren, but, theres something cooler than the MS-190, the carter minimite. this siren is from the UK and is the size of the MS-190. it is extremly old and is from the 1970s to 1990s. it comes in multple voltages : 6 volts, 12 volts, 24 volts, 50 volts and 220 volts (the 220 volt one is AC, not DC unlike the others), so you can choose the one that suits your need. they are extremly hard to find, so good luck trying to find one, and also, i own 4 of them (used to own 5 but gave one away), so i am quite lucky. second, if you cant get your hands on the very rare carter minimite, there is also the MS-390 siren which is larger than the MS-190 and is way better, and these can be found on amazon, aliexpress or even ebay very easily.

Congrats on 100k, I love your video's.

Good job on 100k

0:35 scared the heck out of me!

Congratulations! You have officially summoned siren head! Jokes aside, nice video! And congrats on the 100k subs! Alot of electronic sirens such as the modulators, the EOWS and the Whelen sirens have an alternate wail tone. But alot of older mechanical sirens such as the 3T22, the Thunderbolt 1003 and the super banshee (to name a few) also have the ability to do an alt wail tone as well. Also the phone alert attention tone isn't just used on phones but also TV and AM/FM EAS alert's use them too. (NOAA weather radio has a 1050hz single tone attention tone) Albeit its a continuous tone for 8 seconds rather than pulsed like the cell phones.

Thats awesome! I wonder how you can do that.

So cool

That's siren sounds like the urban legend of siren head

Yooo enjoy your sliver play button!

Please do a review of the EST Genesis.

I love alternate wail

That hi lo wail will probably scare the tornadoes away. Lol

I love Alarm Switches, if its expected, I want Alarms to have a more calm noise, not loud, but can get the job done still, will get people to not be Jumpscared by the sounds.

I have a theory that the mentioned Chicago Loop siren is set to that tone to make it more noticeable in that area due to existing loud ambient noises.

She did those louder sent to Canada and USA Too That's why we saw them Ready Yesterday

Interesting

Hope chicago was ok after that storm. That was a really bad severe storm in that clip

How many different alerts can be on one system?

I could only imagine if schools used that sound for severe weather alerts

To month or two weeks ago I had no problem getting back in shape for a few hours to walk to a house channel to get him

As far as weather sirens, I wish they would go back to the mechanical Thunderbolt that use a rotor and blower. Those made an eerie sound when wailing up, and winding down. They would rise in tone, hold it steady for X amount of minutes, then they would wind down. Around here, they don't keep rising and falling, and they also changed to a digital tone that's not nearly as spooky nor cool as the vintage Thunderbolt sirens. Though technically misnamed as a sound wave isn't a bolt, but a sonic boom. Lightning can be a bolt as the veins streak across the sky. But that's just my pedantic quirk. As for Fire Alarms, the ones that I like most are the ones that rise from a low tone and keep repeating that sequence. And when there are multiple ones, it sounds even more ominous. Back when I was a kid, they were just loud buzzers with trumpet shape horns attached to make them louder. According to my Mother, I got a big kick out of pulling fire alarms and opening alarmed fire doors when I was like 3 years old. While I don't recall specifically doing it, I do recall the noise and did get a kick out of seeing people scrambling. Also, I really HATE this LED nonsense. They're not only deteriorating our eyes, but they're just too bright when looking at, but don't put out good ambient light. For example, when Police, Ambulance, or Fire would go down my street, I'd see the orbs on my curtains and walls, moving. Scared the HELL out of me until I realized what is going on. Now, I don't even notice emergency vehicles are around until I actually look outside to see what the vehicle with the siren I heard or the rumble of the firetruck that happened to be on my street. Halogen rotators are the best, for those applications and for fire horns and strobes incandescent, halogen, lighting up the sign itself is better with also a Xenon strobe tube flashing to grab attention. The reason why the sign that reads fire should also be lit is because, often with strobe, all you see is a flash. Not where it came from.

Didn’t know you liked sirens too!

i FUCKIN LOVE alt wail

Kid:oh no its siren head! Dad:thats not f**king siren head its a f**king federal tornado siren!!

Great

Speaking of tornadoes, Houston (where I live) had a tornado on Thursday before the power outage.

My favorite tornado siren is the Thunderbolt 1003 B series

If you pull down this alarm the tornado alarm will come off and it will make you freak out lol

Est genesies have a good alerting tone too. Something about the carrier tone being between G and Ab makes it sound more urgent and somewhat creepy. The same can be said of the siemens mxl code 3 tone, except it’s between A and Bb Also at 3:23 you could’ve just swapped the front covers lol. You didn’t have to swap the lenses

Awesome!!!!!!❤❤❤❤❤❤😍😍😍😍😍😍😍😍😍😍😍😍😍 Finally got to hear that new eward's speaker strobe device!!!!!❤❤❤❤❤😍😍😍😍😍😍😍 (2:31]‐[2:38) (4:29]‐[4:30]‐[4:31]‐[4:32)

cool

Fun!

I think the alternative wail would be good for a nuclear or biological release. We use the alert tone for tornado, the alternating tone for flood, and wail for attack. I actually think those high pitch screech fire alarms they've been using since the 90s are horrible. I actually feel like ripping the alarm off the wall they are so irritating. In the 80s, my elementary school just had a buzzer. They used a continuous buzz for fire and a pulse for tornado. We knew exactly what it meant, but the tornado pulsing buzz was scary even during drills. We actually did have a real tornado warning once. It made you feel that a monster was lurking around the school. In sixth grade, they modernized it, and no one knew what to do. Funky computer tones that you couldn't tell the difference. That's dangerous! The old system worked, and it worked well. Now, they just want to give you a migraine.

Federal signal has a 15 sec alternate wails just look up the MP3 file site

i know why you did a blue strobe i think its probaly because it means the color of a storm alert?

Here in Florida we don’t really get tornadoes so I don’t really hear any sirens here in Florida

I was kind of disappointed that the alternate wail sound in the in the alarm was just playing a MP3 of a KZfaq video. If you want me to I could recreate that sound and send you the file. So that you have a fresh source of it instead of a microphone recording of it 🙂

Interesting tone, ill admit. Though appears to be a dual tone thunderbolt, just "speakernized". Cool in a way, i suppose?

I see new fire alarms

You should check out the dutch airraid siren. Its very uniqe

are you giving away fire alarms still

It's almost like the Chicago alarm

Tbh I totally agree with you that Chicago alarm is fascinating and it sounds scary too alert the people into going to safety

Is the mentos towers!

Can you do a slow deep whoop with a male massage saying ( may I have your attention please there has been a fire alarm reported in the building ) next video

Put on is that siren head I didn't know you liked videos of

I forgot all about him to electroboom!!!

Wow 10K

Um- (how do I react to this?)

Why does it pop at the end

Bro, I do have a police one, but I don’t have the tornado one😢

i don’t know how peapole wire alarms! i’m drained after wiring a hWl system sensor horn only! 😂

Bro had it on thunderbolt siren

Oh no I’m sorry he’s coming

4:36 Alternate Wail
