Someone needs to get in there and disconnect the damn solenoids from the motor starter! That's a perfectly functional 3T22. It's just wired wrong.

Intakes are shut stopping air from running through, therefore lowering the amount of air resistance, making the chopper spin faster.

I bet I know what's going on. Did you hear the clank right before the siren started? That was both of the dampers closing. And they stayed closed throughout the test. Causing there to be little air incoming into the intake tubes. And with less air resistance, the choppers spin faster. Which causes the pitch to be raised. And with less air, the siren isn't as loud as it is supposed to be. The solenoid's relays in the controls must have shorted out somehow. Best get that checked out.

I know lots of people are arguing about what exactly is the matter with the siren. The solenoids seem to be wired to the motor contacter, meaning the dampers shut when power is applied to the motor, and open when power is cut. TrainsAndSirens1 The motor, even with brush angle tampered with, would not run this fast with the dampers open. The *clunk* sound before it starts (in case you don't know) is the dampers shutting, and they don't open up until the siren winds down. If the rotors don't get air, they have no load. Since the load on the motor is less, it runs faster. In the case of this siren (where nearly all the load is removed) the motor spins much faster than intended, which will inevitably lead to an early death of the motor when the brushes turn to dust or the bearings can no longer take the extra speed. Just in case you're wondering, this siren does test in Attack, albeit on an unusual schedule. They only test Attack during a certain chunk of the year, that chunk is constantly changing.

It’s like a Shepard’s tone. It never stops rising

3:05 I think it's voice cracked

I was surprised it didn't fly off the pole!

Mother of God...

who ever wired the solenoid like that should be fired

Top Horns (1020Hz) Bottom Horns (950Hz)

i think it's really cool how u pretty much just hear the 4/5 undertones from the rotor vanes. it is going so freaking fast, it sounds like a low speed 8/10, or a 4/5 thunderbolt on a low chopper level

I was just laughing at the sound this siren made at the start and at the end. Impressive to see a 3T22 chopper spin this fast. Jesus

Surprised that thing doesn't just fly apart going that fast, or BBQ the motor.

sounds more like an automobile horn

Sounds like the THX opening in movies. Yeah, something's stuck inside it.

Surprised the T-128 can be heard in the background almost clearly the entire duration of the video, this thing must've been heck of quiet with both the solenoids shut. Nice recording!

Sounds like the dampers engaged when it went off in alert. at the end you can hear them open. Interesting how they open slowly from the vacuum, hi side first then lo side.

Eows 1212: You dare challenge my stats?

The dampers are engaged which allows less are in the intake tubes, making the choppers spin faster and the siren to be low in volume Edit: literally started laughing how at the end of the test, the pitch of the siren changed so suddenly I after the dampers reopened

If a 2001 was dual tone it would sound like this

Part of the reason why it is so high-pitched is because the solenoids shut as soon as it starts

That's one high chopper level!!!

Dampers are closed which made i high pitched but very quiet because you can hear other sirens pretty clearly.

How balanced are the choppers in that thing holy cow

Could that damage the dampers by it going high pitched like that though the test and is that a T-128 heard coming around in spots in the background

The dampers reopened when it powered off so it sucked a whole bunch of air in while it was still running too fast which is why it screamed at beginning of wind down

WOW. What happens if the solenoid boxes were not stuck ? XO That will make it high pitched as CRAP. Someone must have messed up the brushes in the motor. This siren is a single phase 3T22 (3T22B). Also, can this siren do attack?

Just because the Thunderbolt and Hurricane Sirens were supercharged. *DOESNT MEAN THAT EVERY SIREN SHOULD BE SUPERCHARGED!* _This is a joke_

THE POWER OF 3T22!!!!!!!!!!!!!!!!!!!!!!

I didn't think a 3t22 could produce a higher sound than it already does...

That was it!!!! This was the one that had a creepy wind down in attack

Damn that shut off sound ☺

3:05

When you pause the video and the sirens are still going...

O_O it sound like a T-Bolt Chopper without the blower both it is strange I hope this siren never get replaced

Sounds like it's about to blow up

THQ

it's that one high-pitched 3T 22

You may hear the 2 T-128s in the distance as well

3:05 the dampers open back up slowly

Mom is EOWS 612 Dad is 3t22A. This 3t22b is their baby. Solenoids close when siren is on, open when off.

That sounds like a Airplane Jet engine sounding very close to the passengers.

It was kinda funny at the end to hear the dampers open and reaaallly scream for a second at full tilt

It sounds like its in G major....

GOD DAMN. something got screwed up in there! know underpowered well this might me overpowered! or brushes got screwed. imagine it with a stuck solenoid box! damn

Well they're saving energy

This is the electro mechanical version of Modulator.

All hail Clyde the Thunder God siren🤴

Is it supercharged

the dampers close when activated

Ok! That’s scary!

oh my thats a bit of mega spaghet going on there, its so high pitched due to one of the dampers being stuck

What a weird siren, the sound was playing a trick on me

It was so high that my I pad cracked

It sounds like a sick 3T22

During my gap year, I want to see if I can get some siren footage.

When it tried to activate i heard a whelen siren in the background and another siren when you listen closely

Heard that clutch snap in at the start! Probably the cause of the high pitch wale, but I think it sounds cool!

I love this

OK. It seems i keep finding more things to say about it, so, as opposed to filling up the comment section up, I'll put them all here: I bet this think is PAINFUL when the dampers open and it winds down. SE3T632 SiraTone EOWS*612 3T22 it sounds like it's running on 70 Hz. (I know it isn't.)

it sounds so weird when it starts up

It has been drinking helium

Damn that sounds good like this.

Is It single phase?

You can hear solenoids click at the beginning, but they dont reset, thats probably the problem.

Dampers closed?

That sounds cool!

it screams on the wind down because of how overloaded the motor was...

0:09 it starts

The reason it is high pitch right as the siren activates the dampers on it closed due to two-tone

the low tone solenoid is broken, that is why it is high pitched

Sounds normal on the wind down since the dampers open up after being shut the whole tone.

The reason why it's so high pitches is because the 10 port row air intake is blocked and that causes less drag. If the 12 port row was blocked it would be even faster because no drag

The reason why it is high pitched is because the top intake is blocked

Ok, that is VERY high!

did they replace the motor on this siren? Or its getting high voltage...

Is that running on a higher voltage

What was that click at the beginning? Sounded like the dampners opening like on a Klaxon CS-8 siren before doing all clear

I got 3T22 at home

The bottom solenoid is stuck, maybe it is because of the air intake made the solenoid close

This has an issue with the RC6A and FC cabinet When they wired it they wired all the inputs into one relay on the FC lmao

Sounds like its a friggen decot , probably the reason why its so high pitched is that it could be both solenoids where closed , its like a vacuum if you put your hand over the hose nozzle the higher rpm the motor goes because its starving for air .

I need that in my fire truck

*Me when a girl steps towards me within a 5 foot radius* 0:09

A klaxon cs8 on stareroids

Why is it so high pitched?

IT'S GONNA BLOW!!

Wow very highly pitched

Mdf board material would've blown to smitherines at that speed!!

Almost all the sirens in Clyde 3t22s are really high pitched

It sounds beautiful

chopper spinning faster than normal

I cannot imagine how loud it is when it first shuts down.

AHHHH!!!!!!

Could you call this an overpowered 3t22?

must be 6000 RPM motor

It’s high pitch because when the damper close it makes it high pitch

Sounds like they’re running the motor on 80Hz.

Thats what its suppose to soundlike when some idiot wires the solenoids up with the motor starter. It sounds that high pitched because there is little to no air going through the intakes, thus causing the rotor to spin faster then normal. Solenoids are supposed to be connected to thier own timing box. (a RC6 penel I believe)

Not even the 2001 siren was as loud as this siren
