I use the Aeon Labs ZW080-A17 Z-Wave siren with SmartThings. It makes a high-pitched whine when plugged in. Does the Fortrezz buzz or whine like that?

I use it with a Piper system and No mine dose not wine or buzz. Only when it's set off or un-plugged will it chearp or sound. Yours might be defective , I would exchange or return it. Hope this helps.

It did not work at all, and when I sent it back I never got my money back or any follow up from them

Mine does not buzz. However, if you are looking for a serious strobe, keep looking. This is more like a weak blinking light. No strobe effect at all.

The Fortrezz siren is silent unless activated in alarm state or in a power loss state with battery installed; also using with SmartThings

I had the same noise with mine. Couldn't figure out why. It stopped when I upgraded to the Nest Thermostat.

I'd send it back if you can--I've had mine for a while and it oscillates just fine with no noise other than WD40 I wouldn't know what to do to it.

I have 2 units. One I bought about 20 yrs ago, the other in the past 6 months or so. Both vibrate (oscillate), Neither make a terrible loud noise. The older one is a little more quiet then the newer. Both are not annoying, but do make 'drumming' hum. I do not leave them plugged in, I empty the tank each time and dry it out. I also put a capful of mouthwash into it each time I use it. The new unit is equal to the old one, except maybe for build quality....it could be a perception thing. so far so good.

That long whistle sound pops on when power supply is not sufficient. At least from my experience. Try a much lower power draw device on it like a mini Christmas light set and see if the problem persists.

Yes, mine makes a buzzing noise when it is charging. It is not very loud, at least in my garage, but I can hear it pretty clearly when I put my ear against the box.

This is just a siren, not an alarm system. When power is applied, it makes a loud noise. And when no power is applied, it is silent.

You need these contacts http://www.amazon.com/gp/product/B001G0MB4G/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 and either http://www.amazon.com/Honeywell-RCWL300A1006-Premium-Portable-Wireless/dp/B001CMLAZ4/ref=pd_tcs_subst_hi_1?ie=UTF8&refRID=164CK9JWFMV7AKD1833D or http://www.amazon.com/gp/product/B001G0MAVA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 to receive the signal and make the alert noise.

when it is on blue (the lowest level) you cannot even hear it. When it is purple (second level) it is a low quiet hum of "white noise." When it is on the highest level you can definitely hear it, but it isn't particularly annoying. I keep it on automatic, so it will cycle up to purple or red if it needs too, but literally 90-95% of the time it is on blue and I forget it is there.

Mine has a very faint ticking (electric discharge) noise when in ionization mode. But it is hardly audible from 2 feet away. Manual says it is normal. As the noise does not increase or decrease and disappears once you push ion button, i too believe it is normal.

I have not wired it in yet. Ones made ban other manufacturer do make that noise when they are powering a load. That is why I purchased this version to test for that. Sorry.

Did you ever get an answer? Mine appears to be buzzing all the time too - I agree. Extremely annoying.

Once in awhile when I power mine up, I get a "rushing" noise that requires it to be powered down and powered back up again. Not sure what that is. It's not interference from my home wireless network. Mildly annoying.

Never had a high pitched noise when plugged in. It makes a high pitched noise when bread pops just to alert you . I would not exchange for a different brand. This has been the BEST toaster we have ever owned.

Mine is noisier than I would expect at times, but nothing that has caused me too much alarm. I thought I heard it click a few times, but so far nothing reproducible or any overheating.

Hi there fellow "alarmist"! My siren has three leads: White, Red, and Yellow. White is negative. If yours has a Black wire instead, it's negative. Red to Positive makes the Siren YELP. If you connect Yellow to Positive, the sound is Steady! That's all there is to it... It operates on 12 VDC.Have fun, Walley Bendz

My bedroom is where I use one of the 4 I bought. It makes a soft whirrrrr sound. More like white noise. Never keeps me awake.
