Allertor 125 siren test in Chaska, MN

[andyt1424]

Must have the 15 Hp motor instead of the 10 Hp.

[Bonemeal2]

To my fellow Minnesotans: have your sirens been tested at all this year? Not once, in 2011, have I heard any of the 2001's fire-up one the first Wednesday of the month at 1PM.

[lilaj34siren]

dang it works well ill give it that most allertors have a slow fire up

[hillbillyprofane]

For whatever reason, the Allertor sirens sound the scariest to me. Almost like they're angry.

[MaterialIssueFan]

I live in Chaska. I hate the Allertor's. I live just on the NW corner of downtown and on my deck not even a mile away I can barely hear the one behind Von Hanson's.

[Eep386]

9/12 port FTW

[Bonemeal2]

I think these sound particularly wicked in Attack Mode.

@SuicuneRider

Here in MN, they're used for tornado warnings, although many were installed during the Cold War and WOULD'VE been used for nuclear war. Doesn't CA have any sort of imminent danger/alert system? I know you've had a tornado or two hit your state every now and then.

[SuicuneRider]

Forgive me for asking such a stupid question but what exactly are these sirens used for? (California resident here.) Tornado warnings? Nuclear warnings? Cause they sound ominous.

[joek0617]

@SuicuneRider all of the above. the've gotten a workout lately

[FordMan055]

@SuicuneRider Mostly tornadoes or bad weather.

[FoolOfThaNight]

ENEMY AC130 ABOVE!

[turtlerocks16]

@FoolOfThaNight >.>

[worlwr2]

Excellent sound and fantastic siren :thumbs up:

[PINKBOY1006]

nice wind up sound :)

[allison2590]

We used to have these all over my city... but they were taken down a long time ago.

[bulldozer950]

i LOVE aan allertor that sounds like this!

[turbocountry]

I have seen Allertor videos on here before and I have not ever seen one run this well. I bet if this siren were to have the motor changed out for battery backup it would be a great siren to have. Its not the thunderbolt but when I live in Bolivar, MO they had 8 of these. The sound coverage is amazing!!! This siren wound up so fast to.

[capdasejb]

monthly tests? sounds kinda like the boy who cried wolf. what if there really IS danger coming, but pple are like F it, its just a regular test. then they are screwed.

[clowj69]

LONG LIVE THE ALLERTOR!!!!

[DasMidnightDrifter]

Whoa, counter-clockwise rotation. Don't see THAT every day!

[TspesVladD]

@DasMidnightDrifter, the majority of the allertors spin counter-clockqise because of it''s potential output. Credit goes to Murrfarms for that knowledge.

[SuperWeaves]

what was the goofy top part for?

[KSE828]

Actually, i read that wrong, the top part actually makes the sound, and the bottom part is the air intake.

[SuperWeaves]

Air intake? How old is the allertor?

[KSE828]

No idea, but all allertors are designed that way. At least, all that i've seen.

[sickVoDKa]

They were produced from 68' to 80' so all are nearly 3 decades old at the least.

[SuperWeaves]

@sickVoDKa used for the cold war?

[sickVoDKa]

I am not sure. Possibly. Vietnam was a bigger foreign issue in the late 60s though.

[penguinmaster7]

whoa! put that sound on my roland!

[beaman220]

I want to take a dump in it.

[bigbluecrane5]

@beaman220 and you would have shit shooting all over the place chen you go to flush it :P

[beaman220]

That would be the fun part.

[flippy941]

XD lawlz

[KSE828]

Why the hell would you make a stupid comment like that?

[seawind0721]

This is one distinctive-looking and sounding siren! There's no mistaking that for anything but an Allertor!

[TspesVladD]

It is distinctive, but some P-10s and P-15s sound like this too.

[twotailedavenger]

Or any other ACA siren. They use the same chopper motor.

[TspesVladD]

The hollar sounds like this too.

[Antipwnsurmum]

No.. they use the same port ratio. The Allertor shares the same assembly as a dual-tone P-10 but there were some that had a 15hp motor.. just like the P-15.

[TspesVladD]

This allertor is very loud!

[kfeyzi]

This is one good-sounding Allertor!

[Johnporter271]

This allertor has a very good ending, but it's very scary.

[vigilante11485]

What's scary about it?

[Coolio65234234234]

question why do you record these things?

[dwronan12]

I don't know myself but we just like them LOL

[bytor55110]

I wonder if these things can be set to rotate clockwise or if they can only be rotated around counter-clockwise...

[Johnporter271]

They can rotate clockwise. The one in Bloomington Minnesota goes clockwise. And so does the red one in Eden Prarie. The one in Madison goes clockwise as well. View these movies, and you'll see.

[bytor55110]

I guess I have seen all of those videos of the sirens mentioned above, and you are right. I just didn't see that. Thanks.

[Blue10AEMia]

They are supposed to rotate counterclockwise, since ACA sirens use directional rotors and stators.

[bigbluecrane3]

not very often you hear them in a high pitched

[Johnporter271]

I like allertors that are bright yellow like this one. A lot of them are this color, but there seems to be other new interesting colors out there now. This siren has a great ending.

[Russell1971]

Awesome siren!! I wish we had those where I live, even though they're already out of production now.

In my area, we have four ACA P-15 Penetrator, built back in the mid-1980s, but our sirens here are nowhere near as loud as the one in this video. The foilage somehow dampens the sound during their weekly test runs, and I usually have to open my front door to hear my neighborhood unit.

Thanks again for sharing.

[carexpertandy]

This one, I'm not sure if this is 10 or 15hp.

[Blue10AEMia]

15hp

[carexpertandy]

Then this is an Allertor 127.

[Blue10AEMia]

No it's still an allertor 125. They went to a 15 horsepower motor because ACA switched motor manufacturers, and it took a 15hp Baldor to run what the old 10hp Doer did.

[PGMEagle]

I must say that allertor runs like a well oiled machine.

[juterman]

I like ACA allertors! its to bad that they do not make these enymore.

[Coolio65234234234]

man dude i leave real close to tht place and tht thing freakd me out 1 day wen i was asleep i thought there was sum nuclear war

[carexpertandy]

That Allertor reminds me of Hamilton County, Ohio's only one in Springdale, except Hamilton County's has a broken rotator.

[bethatonegirl]

That sounds like the SD-10

[Siren1000T1]

Holy Cow! That has got to be the highest pitch Allertor I have heard. 5 stars!

[CoolBalla15]

Dang! That Allertor 125 is very high-pitched! It sounds a lot like a P-15!

[CoolBalla15]

Oops. I meant P-10.

[TroySundt]

hey! its rotating 'federal signal' style...
