@NetCheetah that low tone sounds like a sentry but i could be wrong , the town i live in has about 10 of these sirens total and there really creepy (during a tornado warning )
@mespacetoday well lets say this dude is randomly making this loud obnoxious noise, then you in your mind would probably dislike it. XD But dont worry ol chap i get what you mean lol
There appears to be multiple harmonies while this siren is going off-- like a lower tone that is also sounding off... I don't know if that's vibration resonance or a different siren,but...
they are not that loud, i was visiting my friend up in florida when one of them went off about 50 yds away from where i was and it didnt hurt my ears.
@TheCodmw2rocks I wear a headset when parked close for the test. No eardrum worries. Besides, this one overshadows a retirement RV park. Got to walk up them old folks somehow.
@NetCheetah I'm near an alert siren in South OC... its near the infamous San Onofre plant... but they're not the same sirens as the one in your county... Why??? I find it odd that CA doesn't have the same, uniform sirens...
Any way, sorry to comment after about three years of inactivity...
@Crazymandarinorange Depending on what municipality owns/operates the plant, and the year when it was installed there will be different sirens. San Onofre is run by SCE, while Diablo Canyon is run by PG&E.. Also from what I understand some of them have different audio propagation and are thus suited for different terrain.
@LennonRickenbacher01 They are maintained by PG&E for early warning and unusual situation notification at Diablo Canyon, a nuclear power plant near Avila Beach.
@NetCheetah Also for Tsumani Warnings, Evacuation reasons. San Luis Obispo has the cuesta grade that has fires a few times a year nothing to bad but we did have 2 massive fires one in the 1970's Nearly burned down SLO and one about 1993-1994 that was just as big. So the sirens pose multiple reasons for being here at the Central Coast
P.S. If you are in Avila and they come on when there is no testing...Do your self a favor and get a drink and kiss your ass good by...
Twice a year, the full power test is run last weekend in August. There is a low power 'growl' test done about a month or so before, which is just a control system test. No operator assistance is needed for that test.
This particular siren is located along Prado Rd, approximately 1.5 miles off South Higuera. It is one of dozens located in and around SLO itself, with a hundred or so distributed around south county.
Yep. Thats a 2001 SRNB alright. I believe its one of the latest SRNB models. They don't make SRNBs anymore just 2001-130s which is what my city has now.
It seems a bit odd to me. The only setting that was tested was the full attack siren?? The siren systems, especially the ones that are not really set up for severe weather, such as the ones in Texas, would be more worried about the other siren patterns. Such as the Alert, All Clear and the Hi-Lo, which if memory serves me right is used in times of Biological or HAZMAT Danger. In my opinion, that would be my bigger concerns, but then again, eah region uses different tones for different times.
San Luis Obispo county is home to Diablo Canyon nuclear power station, and these sirens are primarily intended for alert during radiological disaster. They are county controlled, so they can be used to alert for other situations. Due to the geography of the county, and particular in the region surrounding the plant, full attack has the best chance of being effective.
It's actually on the outskirts of town. The video was shot from a block away at high enough angle that you can't see the cars/structures near by. Nice job on the ID.
is that low tone hum from the siren itself or is it a different siren?

@acahurricane1275 It could be that you are hearing the siren over the hill, but they do have a low tone during spool-up.
