Calhan, CO | Federal Signal 500 DH-TT Siren Test [4K]

[@Savage2413Official]

THANK GOD THEY STILL HAVE THIS

Still here as of the day I’m writing this. I do t think they will take it down until it dies. In fact, they may just leave it up after it does die.

[@TriangIe]

I love the 500 DH-TT because of how it’s constantly rotating between an 8 port side and a 12 port side. Creates a beautiful harmonizing sound. Probably the best sounding outdoor warning siren ever made IMO.

[@notanuser-sorry]

It does exactly the same sound the ACA Cyclone and ACA P50 does

[@doggo3354]

@@notanuser-sorry the motor has a different horsepower rating. It doesn’t

[@youraveragepen-7481]

the 12 port side is like an sth-10 (or half of a 2t22) and the 8 port side sounds like an aca banshee

[@MidwestSirenProductions]

Truly the best siren video I’ve ever seen, not to mention one of a rare beast! Keep it up!!

[@lucerozuniga-gonzalez3643]

Hello

[@MaxtheSirenHunter]

@SirenTube if you ask in the whole us, there is 3 in nevada

[@brodie_love]

@SirenTube There is 5 I think in Nevada. They are active, but they aren’t tested.

[@kyezun]

there’s an inactive 550-DHTT down the road from my house

[@sirensofneohio3979]

Yes! Finally someone got a good recording of it! This is hands down the best video ever!

[@iowansirenrecordings2454]

Easily the best siren video on KZbin! I cant wait for other videos to come from you if they're gonna be this good!

This has to be the best 500DH-TT vid I've ever seen, hands down Amazing capture, DaSamNudge!

the sound, the looks, and the vibe it's giving and the sun it's a cure for my depression

Pretty much an early ACA P-50. I hope that they still have it today, as it is a VERY rare siren

[@abandonedaccount3313]

Best siren video hands down. Earned a like and a sub

[@geaeliska858]

great video. Loved the quality in full HD and even the sound quality. You could here the control box clicking when the siren activates.

[@djscrizzle]

Ain't nothing quiet about a NEMA size 2 or 3 DOL motor starter slamming in. This puppy sits on a 70 amp 240v 3 phase hi-leg delta circuit. That's why it's got such a fast pick-up when the power applies.

[@NeilPrasad_1905]

Attack signal ( Fire ) at 0:11 Alert signal at 4:42 During test - Wind downs at 1:11 , 2:41 , 4:11 and 7:41 Windups at 0:11 , 1:41 and 3:11

[@WilliamNealyMusic]

Fire signal is a short 15 second version of attack signal constantly going on and off, it didn’t do that at 11 seconds in the video so it’s just attack. Just so there’s no confusion for anyone.

[@radiosnmore1225]

BEST VIDEO OF THIS YET I ACTUALLY LIKE THIS SIREN

[@grace-jc6jp]

SAME

[@wadessirenvideos6750]

There are probably less than 25 of this model of siren left in the United States still in use today. This design of a rotating siren is rarely seen nowadays. This one looks like each side has a 90° beam of sound, being very efficient at doing its job. Sounds like a P-50, but with a faster start up.

[@Sipex6484]

I think there are less than 10. I know of like 3 in new york, there's 4 or 5 in nevada, and then there's this one, the only active one.

[@Vacuum_And_Siren_Expert]

​@@Sipex6484I think Sugar City 's DHTT is active

[@Siren1000T1]

The three users who disliked this video, I wonder what was going through their minds. I mean what did they think they were going to see? Otherwise, excellent video and could not have done it better myself.

We can use some warning sirens in Lenoir City TN and through out Loudon County TN and all over Knox County and Knoxville TN.

When does Calhan test? I’ve got to come here...

first Friday in May. times seem to be different every year but that year it was at 7:00PM

@@DaSamNudge Thank you so much

[@SouthernRailfan]

That is an awesome siren. We can use more of them sirens around. Should defeat Welen sirens.

[@United_HVAC_and_Fans]

Whelens are still good. But i dont think they hold up to these.

[@SouthernRailfan]

@@United_HVAC_and_Fans I agree. But that was a good attention getter by the way one side was high pitch and other side was medium pitch.

Is this thing still alive?

@@SirensAndAlarmsOfNorthernIL i heard that another is activate just not tested. This was around a year ago so I'm not sure of its current status.

[@charlie_nolan]

Does one tone play out of each side? That seems like an ineffective way of making a dual tone siren (at a distance)

[@borkluchtalarm]

One side is 8 port, and the other is 12 port. And, you're right. It's kinda ineffective.

[@sy3the384]

Why does it sound like a p50

[@PlatinumEagleStudios]

Both use the same port ratio, witch is 8/12

[@Tigers9596]

Amazing work? Why did they have that weird testing cycle? 1 minute of alert 3 times or something?

[@DrpanProductions]

Attack from older videos is their tornado warning signal. Alert is all clear.

[@DaSamNudge]

I think that’s how Calhan’s warning protocol works, it’s not exactly the attack signal but I know that they use a 3 minute alert tone for all clear.

[@SETX_Sirens_and_Rail_02]

3 one minute blasts with 30 seconds between blasts for take cover and a 3 minute blast for all clear.

[@TheJakeman789]

They still haven't gotten something newer and more reliable? They need something new and louder. Still surprised it's still around.

[@DaSamNudge]

it’s plenty loud, and obviously reliable, it’s definitely way louder than Lakewood’s Whelen system

[@samschannel531]

Wasn’t this louder than the Thunderbolt, but over advertising for the Thunderbolt caused it to outsell this?

[@TheJakeman789]

DaSamNudge I’m sure it is, but I’m concerned it won’t last much longer. It can’t go on forever.

[@SWMOWoodsman]

TheJakeman789 Idk if y’all knew this or not, but she’s got a 3 phase motor. 3 phase Federal sirens never die unless something catastrophic happens to the motors such as a lightning strike
