Emergency Alert System Sirens

Video taken during the annual test of the San Luis Obispo county emergency alert siren system.

This system is designed to alert the public in the event of radiological or other natural disaster. The system is tested at full operation once per year, and is a process involving hundreds of volunteer observers. The County Office of Emergency Services in union with the Amateur Radio Emergency Service and other organizations provide much of the logistical ground volunteers needed for such an operation.

 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.

Goodbye eardrums

@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...

[NetCheetah]

@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.

Great vid! This is in California, right?

[acahurricane1275]

@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 )

1 person lost his eardrums.

[ricofojas2011]

[poke931]

@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

[mespacetoday]

who dislikes a sound....really?

[epicstuntman10]

@101kipkayfan so it everyone around it hears!

[KosukiFire]

@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...
