3T22 Federal Signal Siren 

keep the classic sirens alive

dude the siren is perfect

I like how the birds flew off just seconds before the siren went off..like they knew it was coming.

coolest sounding of all of the sirens! this is the king Tbolts are next!

The clicking sound is the air flappers. The flappers can be set to continue to flap during the wind down so that the hi-lo sound will continue during the wind down. The flapper cut-off time delay is adjustable to suit the user.

This looks/sounds like it's from the 90's.

Sounds like one intake stays open while the other opens and closes.

I wish they still made these and the 2t22's

the windown sounds awesome!

The damper control (sometimes called flappers) has an adjustable time delay that is independent of the siren motor timer. The damper control timer can be set to continue oscillations after the siren motor is de-energized, and is winding down. This department has their damper control timer set to stop oscillations about half way during the coast down. It could be set to stop at any point during the wind down. It's a matter of preference.

Lower "valve" (damper) is remaining open. Maybe asimple as no power getting to it. Normally open, power closes the damper.

The 3T22 has solenoids to make for additional signals. The 2t22 does not have this solenoid and thus can produce these tones. These signals include hi-low, and Pulse, and can be used in combination with alert for a steady tone, or attack for a wailing.

kinda nice to hear this 3T22 sound the fire signal/attack tone.

l.o.l. @ 0:06 those birds must have shit themselves when that went off :P

Please film this siren again. Its very intresting. I mean this paticular one.

They may have also felt the motor jerk when it was first turned on, but before it got fast enough to produce noise.

The 3T22 produces 3 Tones: Alert, Attack, and Hi Lo. The 2T22 Produces 2: Alert and Attack. As a result, om;y the 3T22 has Solenoids to produce a Hi Lo sound.

I newer heard siren my town And I like the siren and tone

a 2T22 is this siren but can only do attack which is a steady up and down sound and alert which is one pitch and this siren in the video is a 3T22 which can do attack, alert and a 3rd signal which you can hear in the video which is a fire signal that is the alert signal but solenoids block the intakes creating a Hi Lo signal *breath*........

@ twotailedavenger: Judging by the 'frame-line' at the bottom of the screen, this is a recording from an analog camera, but from a bad tape.

I'll past your comment on the the fire department. Maybe they can take a look at it the next time they service it.

@iwnproductions dont forget with the 2t22 can also do fast wail

@Surgethearcticfox The 3t22 is capible of alternate steady and alternate wail.

@Ouranos94 No. It has been on a pole since it was installed in the mid-60's.

@Surgethearcticfox Other than that they look the same, the 3t22 is capable of alternate steady and alternate wail. I hope this answers your question ;)

Yes. It's a normal function of the 2T22 and 3T22 sirens.

@Surgethearcticfox The 3t22 is capable of alternate steady and wail (but doesn't alternate durring wind down/wind up

It sounds like the bottom solenoid damper is stuck in the open position, making it sound "Pulsed", instead of the normal "Hi-lo".

Good job to whoever rebuilt it. :))

The 3t22 has solinoids, what makes it capable of producing hi lo.

The birds are like " WHAT THE HAYL IS THAT NOISE?! GET THE NEST OUT OF THAT THING!"

Thanks for the info. I'll pass it on to the firemen. The sound might also be little distorted because I was in a vacant lot between two buildings, so you may be hearing some echo. Also my video camera sound pickup capablities may have been a little overwhelmed by the extreme volume of the siren. Maybe I try it again sometime with a better camera and sound system.

never saw a red 3t22 before but now i have

@mikey125612 Exactly, the lower damper is stuck open so it makes a sound like WEEH WEEH WEEH WEEH WOOOOOOOOOOOOOOOOOOO instead of WEE-WOO-WEE-WOO-WEE-WOO-WEE-WOO

@Surgethearcticfox the difference between the federal 2t22 and the 3t22 is that the 3t22 can do hi lo mode.

@deeredad That's because the lower solenoid is broken. >.>

A 2T22 can only do steady and wail, as for a 3T22 can do steady, wail, and Hi-Lo because it has solenoids that dampen the air intake.

@Surgethearcticfox I don't know. Maybe it's the year made or the optional features. You'll have to ask a siren expert.

whats tht sound tht sounds like DA DA DA DA during the siren windup and during the steady signal

2t22s and 3t22s are exactly the same except the 3t22 can do attack, alert and hi-lo, while the 2t22 can only do attack or alert.

the low tone damper is stuck, it isnt the pulse signal, and it's a very old video, so the motor is probably very healthy.

these are so weird 1open and closes and 1 stright foward open

awesome video

@Surgethearcticfox Well (im not really and expert) but the difference in the 3t22 can do hi-lo signal using a damper while the 2t22 doesn't have a damper so cannot do that signal.

@deeredad 2t22 dosen't have soloniods so the 2t22 cant do hi-lo but 3t22 does have soloniods

The Yellow is CD Yellow (Civil Defense)

2T22 Because it only does 2 signals Alert and Attack the 3T22 does 3 signals Alert,Attack and Fire Hi-Lo

Oh it's red, how awesome.

he's backing up!!

Faison huh? I'll have to drive down there to listen to a Noon test. Faison is halfway between Wilmington & Raleigh.

3T22's are like the same as 2T22's but the 2T22 does not have the 2 solenoids. D: also it can actually make 4 things (talking about the 3t22) it can do alert it can do attack it does hi lo and it does hi lo WAIL.

how much would one of these cost used? I only ask because I wouldn't mind getting one and putting it up on my roof

@gnutelliums whats the difference be tween the 2t22 and the 3t22?

My God! Now there's some memories there! The next town over has one of those sirens and they still use it! Sounds just like Ft. Edward. Also sounds a little like the one in Ft. Johnson which was the department I belonged to. Do you think you could burn me a copy of this because I could use it for my structure fire scene on the model train layout at my model train club.:)

its the opposite way around the 2t22 doesnt have dampers and the 3t22 does

haha the birds were like oh shit

lol the birds flew away

Repainted red. It was yellow. I don't know why they decided to paint it red.

@deeredad the difference between a 2t22 and a 3t22 is that a 3t22 can do hi low as a 2t22 cannot a 3t22 has selinoids and a 2t22 dont look at the name.....3t means 3 Tone and 22 means 22 horns...22 ports so its 3T22 and 2 Tone 22 2T22 its actually simple lol

In the wind down after the high notes why does it make clicking sounds like HI click HI click Hi click HI click

@acahurricane1275 manually yes but timer ran no it cannot

@yoyobass100 I think around october of 2006

what year is this and is this a film camara

sounds like the low solenoid is broken

Is the lower damper stuck or the solenoid for it is broken?

the 3T22 has dampers that make the Hi-Lo/Fire call. the 2T22 doesnt.

Its sounded like that for years, reminds me of grandmas :)

After 1:18 if you turn up the volume, you can hear a tapping noise, like this: da *tap* da *tap*

was a federal signal siren red 3T22 siren is a fire siren.

I think the sound might have just been a bad tape.

Is one of the dampers stuck or is it doing a pulse signal?

@RawrinVideos Why do some people take bath salts?...

i havent seen this siren the past few times ive been through faison. where is it?

that's a high & low tone

JVC VHS-C GR-AXM18U Edited with Pinnacle studio

I've never heard of a red t-bolt before. -_-

At first the dampers are working fine, but suddenly the bottom one stops .

it wasnt it looks that way, but if u look close the flag is on a white pole, and all the way up that pole

Why did hi-lo mode stop at 1:23?

Newly rebuilt? The low side intake isn't working.

Did this used to be roof mounted? It looks like it has a roof mount setup.

3T22's are like the same as 2T22's but the 2T22 does not have the 2 solenoids. D:

I believe the difference is that 3T22s can do the hi/lo, while 2T22s cannot.

Something is wrong with one of the dampers

The 3t22 can do a hi lo signal like in this video.

Bycial? What's a bycial? You'd be surprised how many younger folks are also into horns, bells, whistles and sirens.

@Surgethearticfox a 3T22 has a hexagonal pipe going down and a 2T22 has a round one.

Are ya sure you're not just hearing the tone-pulsing effect there?

yes

Sounds like only the high tone damper is actuating.

Where is this?

@Luckyb41103 3t22 has solenoids, 2t22 doesn't

the poor thing needs a coffee its not well

its the video. oold video.

its odd that its painted red in this video

it's doing a hi lo/fast wail

I have seen a yellow 3T22 but I haven't seen a red one!

When was that taped?

nice

what is the difference between a model 5 and a model 7??? ( i know it has nothing to do with this video but nobody has told me on any other... :( i saw a lot of friendly ppl here so i thought i would ask...)
