It dosn't sound that horrible, but it dosn't sound healthy, the pitch jumps around. Not sure if that is voltage problems or not.

In the video, it dosn't even look as if it has a power source going to it. Maybe the batteries are low and no AC power source has been hooked up yet?ver tum wrote:That's the worst sounding 2001-130 I've ever heard. It sounds really underpowered, and the pitch does jump around a lot. I would almost bet that that siren isn't even producing 128 DB at 100 feet.
Makes me wonder if this siren was used recently. The pitch isn't even correct, nor is the rotation. If a siren is used recently, (according to our EM director in this county) the 2001 when tested they will run for a max of 5 to 10 minutes during a test. After that time the battery backup takes a day or so to fully recharge correctly. However, looking at this 2001, I see a tilted panel so it probably is just running off of batteries and solar power.2t22boy wrote:In the video, it dosn't even look as if it has a power source going to it.

The more I listen to this siren, the more I like that tone being thrown out. Much more ear pleasing then the shrill tone it makes at full RPM.ver tum wrote:That jumping pitch thing really concerns me, because every single one of the 2001-130's I've ever heard do that to some degree. Even if this one was getting it's full supply of power, it's pitch would probably still jump around. I think that there's definitely a link between the jumping pitch, and the siren's rotation. That can't be good for the siren.
Man! A day for batteries to recharge? Better hope we don't get a severe weather outbreak next year, the sirens would only be able to be sounded twice. Last June a Tornado was reported just South of Topeka, Shawnee County sounded the sirens about 5 times, I can only imagine what some of our 2001s were sounding like.md5 wrote:Makes me wonder if this siren was used recently.

I wouldn't be too worried. If you remember back this past year in Johnson county KS, lightning or something related set off a tornado siren for a good 30 mins, if not longer according to media. It was running on the main power, not the battery backup. however, when the siren was D/C'd from the main power the batteries kicked in and it kept going until they cut the power from the batteries.2t22boy wrote:Man!
