Re: City of Raleigh's Flood Warning Sirens

Wow, dredged this one up from the archives!! OK, I'll try to clear up a few things. But know, I have not been directly associated with the system since, like, late 2010. That's 13 years. 1) Test with Shearon Harris? No, certainly not when I was asociated with the outside contractor doing the mainten...

NCSU - WolfAlert System.

Just found out that there are 11 WolfAlert sirens across the campus. Guess I gotta go round and find the rest of 'em!!

Discussion on sirens in communities in NZ.

Just came across this fresh article from New Zealand. https://www.stuff.co.nz/timaru-herald/news/129258363/why-we-still-have-fire-sirens-in-some-small-community-volunteer-fire-stations Still good words to have: When that siren is going off, someone in the community is asking for help. It's that simp...

Re: Siren Mystery

Meh, maybe not, may be just badly programmed. Check these other things first. Quick other question, related to the tones: How did whoever know what tones to program into the decoder? Were they just 'handed out' from the 911 center? Again, sometimes errors can creep in without anybody seeing it happe...

Re: Siren Mystery

1st quick pass of all that audio thru Audacity, looks like all the tone sets are 1 sec. A tone, 3 seconds B-tone. Standard. I'd say it's still something on the decoder board. Notice starting at 0:40 seconds, there's one tone, and Tone 1 light comes on, and stays on thru the 2nd tone, even tho they a...

Re: Siren Mystery

Haven't had a chance to listen closely, or put the audio thru Audacity, but the audio I hear is rather scratchy; how is that being added to your video? Is it a separate radio or scanner, or does the decoder box have a speaker? Edit: removed comment on something I hadn't read properly. Start brain be...

Re: Siren Mystery

OK, couple more questions: (blunt): How good is your electrician? Is it just one contact closure to start the siren? Siren runs the same for each of the 2 tone sets? Or is there one siren sound for one set, and another siren sound for another set? This, I could see would be 2 separate contacts. It a...

Re: Siren Mystery

Late to the party, but here are some other questions, just kinda random, but thinks to look at/find out. What was the radio and controller brand and model of the old system? Who was the company/contractor who put in the system? (I know, this may open a can of worms) Just a thought, are there any aud...
