The hazmat tone you hear is ASC's Fire tone. It's basically a more stretched out attack signal. After the test is done, the system is polled for each sirens status.
Beautiful recordings of the signal, its called Compulert and was developed by American Signal Corporation. There is an encoder modelled CSC-960 that generates the FSK signals heard, decoded by a special receiver on the siren's end.
Gotta love the sentry! I wonder why and when did Porter county decided to be like LaPorte and switch to FSK. I really miss their good old DTMF triple activations
Is there a way to decode these transmissions to see what these tones are communicating? Or is that something that is limited information? Im curious because if you can decode those tones and see what they're trying to transmit, Id love to see whats happening in my area. Just recently got into radio technology and ive been really interested in all this stuff
@@seanjuth run again you can actually decode it by simply recording it and replaying it and it would actually activate those sirens it's easy to do it in Loop mode
The best way to get your frequencys in your county is radioreference, also its a Baofang but IDK the model number but it could possibly be a UV-5R (I have this model)
@@novawarningsirens Oh, I didnt know, I got that UV-5R for my bday but thanks for letting me know about this, im still trying to confirm what channels has the FSK activation for my county. I will look into this
NOAA radios are totally separate from this handheld, and this radio in the video (a baofeng uv-5r) is not all that special, just a basic analog transceiver with the dispatch frequency programmed in. It’s also illegal to transmit but not to listen
How do you find the frequencys where the tones are broadcasted to activate the sirens? I do have a scanner, and I can receive frequencies from 108-199 and 400-512. The scanner is a Uniden SR30C.
Those DTMF tones that you heard that sounded like a phone dialing at the end it was the pound of symbol that went through six times and then it dialed 12 so that basically knows that I know how to decode that shit so anybody could set that shit off and it's using that compulert system which is why you were hearing those squeals and whatnot prior to the DTMF on the VHF repeater system

The decoder is called an ASC RTU. I bet the CSC-960 is what does Two-Tone as well as those encoders can do DTMF and Two-Tone besides FSK

The ambiance sounds crazy man
That’s Sounds Like Donna From NOAA Weather Radio.
I think Donna found a new job
I Miss Her.
Who the heck is Donna
@@scottconner5401 she used to be on noaa Weather Radio she was a female who recorded computer voice.
also (if you dont mind) i would like to see more monthly tests with the scanner
It’s a hand-held ham radio
@@MegaUh if you had it, you could try to tune to your NOAA frequency to say 162.XXX (X for digit)
and its probally hazmat. here in hawaii there's a hazmat tone (different from the mainland since we got a "unique" siren system.)

The FSK protocol you hear is proprietary, so no you can't decode it.

@@414RadioTech you clearly didn't read my message correctly
Alert Attack then Fire Signals the Fire Signal is a longer version of the Attack Signal usually a longer steady then off cycle
Thats really cool! Few Questions, What scanner do you use and how do i know what frequency to go to the hear the tones?

@@SailorKirby Normal UV-5R. Would suggest a bc75xlt because baofengs u can transmit just by pressing ptt, so i wouldn't reccommend a uv54
@@novawarningsirens Oh, I didnt know, I got that UV-5R for my bday but thanks for letting me know about this, im still trying to confirm what channels has the FSK activation for my county. I will look into this
@@SailorKirby well, theres a setting in the menu to disable PTT, so if you do that, no worries on transmitting,
@@novawarningsirens Ok, btw what does ptt stand for? And is that how you hear the FSK activation?
The Closest One I think Was A Sentry 10V2T Siren And The Faint one Farther Away Is A Federal Signal 2001
Yea
very cool! does it work with regular noaa weather radios or do you need a special radio for that?

I've been trying to do this in PC as well, but they haven't done the test in 2 months
What does the DTMF activate?
How did you find the channel for the encoder?
I love that walkie-talkie
same
i own it
That is called a scanner. It can be used as a walkie-talkie but usually it is a scanner
@@SirensAndAlarmsOfNorthernIL the more proper term is two way radio
@@SirensAndAlarmsOfNorthernIL its a transceiver not a scanner
@@chipweather Ik now lol that was from a year ago
the voice who was speaking was the Crs old gir voice

Radioreference
My city uses “Project 25 Phase 2”. What is the frequency of it?
What is the name of that tone?
what scanner is this?
3:12 what kinda scanner do you use
Its a baofeng UV-5R
How did you find the Fequnces
What would I look for when finding frequencies?
@@CoolSirens1000T ok. Thanks.
Isnt that a Baofeng UV5r
It is, i have 6 of them and they are cheap to get. Pretty useful when u are into HAM radio
@@MrIdklolidk I work at walmart right now and a lot of us carry them because they are so much cheaper then the proper radio.
What antenna are you using
um to my knowledge the siren should have motor cooldown
?
siren cool down @@ElevatorWasher5000
don't burn out the motor @@ElevatorWasher5000
Nice sentry?

The DTMF sent was a very common code for older units
It was 3333348
can you reply the link so i can buy a Siren Scanner plz
Well the model is a Baofeng (Possibly a UV-5R)
Why haven’t u been postin?
What radio is this ?
Some type of Baofeng Radio, possibly a UV-5R
Will this work the fire department sirens??
Depends if your county has a station that broadcasts the scan codes or uses them
0:35 Donna from NWR??
Sounds like it
Is Laporte 151.340?
The lady said Porter County
@@OhioOutdoorWarningSirens Of course you would be watching this video
@@CentralOHSirens you watched it too lmao 🗿🗿
@@OhioOutdoorWarningSirens yeah but the difference here is i didn’t hack a sys- nvm

Donna?
