yes...better than the eq that has become so popular. you can actually hear this siren. i think LA county still uses these on engines. or perhaps a newer version that doesnt sound synthetic.
The A refers to not having a brake installed, the brake was an option, if it was supplied with a brake, it was a Q2B. The major changes over the years were in the clutch assembly and the motor. Newer Q's have front grills that have perforated metal covering the center where the F logo is. The older grills are open as mine is.
This siren is 12 volts, the Q was introduced in the early 1950's and it was available in 6 volts because a lot of vehicles still had 6 volt electrical systems. I have a 1963 Federal catalog and you could still get a 6 volt or 12 volt model at that time.
Thank you very much for that information. It is interesting how much the sound had changed over the years, unless the current models just have to be "broken in" first? They've lost the characteristic growl to some degree and coast down much faster. Thanks again!
No you're mixing it with the Q2B which has a build up before going down, it's like a Q wail siren, this one is a Q2A and is a manual Q siren. I prefer the Q2A over anything else because it allows you to control how load the siren is depending on the traffic and the speed you're going, unlike the Q2B which plays automatically.
@@peacefulrevolutionist No, you are thinking about the EQ2B which is the electronic version. It sounds somewhat close to the classic Q. The EQ2 does have the ability to auto wail but not the Q which uses momentary contact switches (through a high current solenoid).
@douro20 Good to know! I want to install magnaflows, flowmasters, or cherrybomb glass packs...which one would sound the best and somewhat of a low tone/grumble?
The new Q's use a one way bearing for the clutch and I have noticed on CZcams fire apparatus videos that many of them have a short coast time. My Q's have the simple ball & ramp clutch and I know both of them are over 40 years old and had the heck run out of them and the clutches still work great. I guess it was a cost saving to replace the ball & ramp clutch with a screw clutch and then the current one way bearing. It also helps to have a well broken in rotor bearing for long coast times.
@robertgift I personally love the high pitch of the Q (you probablly could've guessed by my username...lol). It gives me chills when it screams at full power. I find lower pitch sirens to be less satisfying. The high pitch of the Q is not just due to the number of ports, but also the high speed of the motor. Of course, the faster it spins, the more air it pushes through the ports and the louder the siren is.
one of our engines has a Q2b and we had a bad snow storm last winter and the siren doesn't roll as long as it should anymore. what do you think is wrong with the siren?
how much does somthing like that go for? im asking because ive re done my whole basement with fire fighting equipment, and my son and his friends always sleep over. And a tradition of mine is going down there before they get up and waking them up with an old alarm bell ive installed and it would be hilarious if this was installed to. i know its loud but still
where would i be able to find something like this as a collectible or even a grover stutertone second hand off a decommissioned vehicle or is that just not possible? I can always dream right
I am using some custom made 1 gauge cables 10' long to the siren to keep the voltage drop to a minimum and 2 8D batteries in parallel for a power source. The 2 8D batteries power a traffic control arrow board that we use in our business.
@AppleBlossom7713 The easiest place to find them is on Ebay, there are usually at least 1 listed at any given time. Expect to pay $300.00-700.00 depending on condition.
Is this a 6 volt siren? I'm looking at sirens on ebay and such and I saw a Q2a once and the seller stated it was a 6 volt siren not 12 volt like the modern sirens. Is this true for older 50-60s Qs?
Most mechanical sirens sound output is measured in db (decibles,measure of sound pressure level). Federal claims 123 db at 10 feet from front of siren. Most electronic sirens are very directional, most of the sound is directed foward by dssign of the speaker, with a mechanical, most of the sound is from the side.
Nice. Thanks But lets hear whole wind-down. Especially good when close near end of wind-down. I would paint the rotor's front edge half white and half black to visually show rotation. I painted one rotor vane of my Federal Signal 2t22 air raid siren (tornado siren) to show rotation better. (Also, after each monthly test, when I line that vane up in a particular stator port, the vanes of both rotors are blocking their ports, keeping out birds, bugs, snow, etc.)
maybe its just me or maybe there actually is a pitch difference.. my department has a ladder truck with a Federal Q2A and its pitch is a lot higher than our engine that has a Federal Q2B
How many ports in this beautiful siren? Federal Signal made a mistake having it attain such a high pitch. Better to have HALF the number of ports so that the sound would be an octave lower and carry farther. Hey, why not wind down to silence? Did I post here before? Is there a way to knowithout searching? Thank you.
@Henry455 Thank you. Don't I know it! At a 02:30 heart attack scene!!!, I stupidly accidentally hit our ambulance's Q2A foot switch. Quickly I tightly sealed the front (intake) with my coato diminish the volume as much as possible. I have a working 2t22A which averages 2-1/2 minutes from 3,450 rpm to rotor stop. Last 30 seconds or so is fairy quiet. Wanted to seal the bottom intake to see how much longer windown becomes. At 5,300 ft ASL, our less dense air does not impart as much drag.
+Edaan Friedman Years ago Federal made a painted model of the Q with no back cover and painted instead of chrome plated. This was a Q1, they also sold the Q without a brake, this was the A model, the optional brake was the B model. Now all Q's come standard with chrome plating and brakes.
@robertgift The Q has 14 ports and I agree the pitch is too high. My Sireno 40010 has the same dia. rotor and has 12 ports but sounds almost identical to the Q. That could be due to motor rpm's. The reason for no wind down to silence is strictly because of video file size. The slower the rotor turns, the longer it will coast if that makes sense. As the rotor slows, it is not working to move as much air so the drag becomes less and less. Watch the first part of my video "Old Q2 Rebuilt".
I HATE THAT! Are you referring to the "siren brake"? Pushing a button causes a pad to be pushed against the rotor to bring it to a much quicker halt. I like it when it coasts down natually to inaudibility.
Do not want to get involved in any dispute but I do like to keep facts straight on my channel. Federal Q2b MSRP, $2,374.00, B&M SC, $2,133.00. SC weighs 27 lbs., My Q weighs 33 lbs.
Sounds like angels coming to the rescue to me!
Why?!
OH YEAH!! The sweet sound of a Q....
A REAL Fire Truck Siren

That is my favorite siren. In the mornings when we start the trucks up and check the lights and siren I look forward to hear that one

Gotta LOVE a Q! Strikes fear in the hearts of men.
123 db's that are music to my ears.
the sound of this thing growling is just....beautiful
Awesome! I love the wind down!! The Q is such a beautiful sound!
Love those old Federal sirens
Next time I run a fire call in my truck I'm playing this over the PA
Be immensely cheaper.
Alex Neumeister nice picture!
I wish I could. We're only allowed blue courtesy lights
the power it take to run that it would drain ur battery
Jason Powell it's not a real Q. Playing the recording over the PA.
All the firetrucks where I live have Q2B's. Never seen a 2QA before. :)
Caroline Cunningham This model does not have a brake. The Q2B does. The brake helps stop the siren when the truck arrives at the scene.
Caroline didn't say it had a brake...
this is my favorite siren
i just love the sounds of these when im on a call...
Just need the guy laying on the horn
45barber1 EXACTLY THATS THE BEST PART
Music to my ears
wow that just ran chills down my spine, very nice haha
i only played this so my dog would howl... and he did
Hahaha! XD
The best sounding, and most effective, siren known to man 😁👌👌👌👌👏👏👏👏👏

This sound makes it official. Some bad shit is goin' down.
i like the tone on this one. looks snazzy too
I would like some info on where I can purchase one of those please
@douro20
Good to know! I want to install magnaflows, flowmasters, or cherrybomb glass packs...which one would sound the best and somewhat of a low tone/grumble?
I also rescued riley McMurray with that loudest fire engine siren in the 1969 tv show called sesame street
Pullin' up to the scene, jumpin' off, pulling hose, masking up...getting ready to go to work...

nothing like a federal Q- nothing else sounds like them in the world- good vid!!!
mind if i use this for a report on the old q vs the new q and driver responce?
one of our engines has a Q2b and we had a bad snow storm last winter and the siren doesn't roll as long as it should anymore. what do you think is wrong with the siren?
Ohh my god !! I love it !!
Can Someone Explain To Me The Difference Between The Q2A And The Q2B, is this the one they mount on FDNY Rigs or is It always the Q2B
i like this video nice high pitch sound great video henry455
Very nice siren!
how much does somthing like that go for? im asking because ive re done my whole basement with fire fighting equipment, and my son and his friends always sleep over. And a tradition of mine is going down there before they get up and waking them up with an old alarm bell ive installed and it would be hilarious if this was installed to. i know its loud but still
Can you make a video of the Q2BS thats the one we got on our ladder at my station
Do you have one like that one for sale or where you bought that one. I'm looking for that same one, but can't seem to find one.
That is what a q should sound like
Earlier models of the Q were available without a brake (Q2A). The model with a brake was a Q2B. They are only available now with a brake.
where would i be able to find something like this as a collectible or even a grover stutertone second hand off a decommissioned vehicle or is that just not possible? I can always dream right
That would be the Federal Signal company, the same people who invented the Thunderbolts and Federal 2001 air raid siren.
How long will it stay good when running on full power
where can you get one of theas?

1:00-2:03 fav part love the slow shut down
Where can I get one
i wont one ware did you get it from
how did you power this, doesn't it take 12V and 100amps?
lol that will wake up your whole area with that
Were there substantial changes between the "A" and "B" versions?
can i get just the audio to that??? that would be sweet...
I want this on my 1999 Crown Victoria!
Nice.
Thanks

You are SO right!
Still the best.
@PNSB101 I have a brake for this one but did not install it. You can add brakes to A series sirens if you wanted to.
You can get them on Ebay. They go for alot, like around $300-$700.
is Q2A larger than a Q2B siren
How to perchase thish system

That got some attention in the house. lol
awesome 6 chord scream
No, the A model came without a brake, the B model had a brake installed. All new Q's come with a brake as standard.
We have a Q2A that does not rev as fast as this one. Thinking ours needs some cleaning and lube.
What is the difference with the model q and q2.
also why is there like q2a, q2b, what are the letters for?

How do you have so many sirens?
Also I'm getting a model 28 is 300 bucks a good deal?
+Edaan Friedman About one of the best you'll find really.
I got a C5 for $165 and a 76A for $450.
The C5 is from Ebay, it works and I now sent it to B&M to get it fully restored.
The 76A is from Craigslist.
Edaan Friedman
exactly how loud are these sirens? can they be measured in watts, and if so, how many watts?
nice vid
They can reach up to 140 decibels.
Nice

we use these on all our trucks
This siren is on some of my firetrucks on roblox
Ebay, there is at least one listed now.
Q2B has a electrically operated brake to stop the siren from coasting.
Sounds just like a fire truck
I
This is one of the sounds used in the Photon Sirens mod in Garrys Mod!
I can send you a HQ MP3 audio file taken from the raw video if it will help. Just PM me your email address.
cool
I HATE THAT!
Are you referring to the "siren brake"?
Pushing a button causes a pad to be pushed against the rotor to bring it to a much quicker halt.
I like it when it coasts down natually to inaudibility.
I could go for some Q action right now. Haven't been on a call in a couple months
Just got back from a medical call
We run a brush truck for medical calls with covid
I could also use some Q in my life right now

Sure, no problem.
Sounds like the Fire Trucks in New Blockers City in Roblox
Wish our fire apparatæ Q sirens had 1/3rd the ports.
Lower frequencies penetrate vehicles better and carry farther.
Pretty much ALL of the Seminole/Orange county fire trucks have this siren
