Does yours make a siren noise occasionally? Like mine does.

I have not heard a siren noise, unless it's a low-battery signal, and I haven't run my batteries down yet.
1322004
No, I've never heard that, but I haven't had it turned on for prolonged periods.

The signal "beeps", twice when left light is on and 'beeps" once when right is on. I do not know what would make it sound like a "siren" Mike

Hello, our signal makes ore of a "beep" noise. I would not call it a siren.

No, it doesn't! And despite being very accurate mine created a buzz after some time. I think it's the battery or sth. else ratteling at certain frequencies.

Not here. I would unplug it and see if it still happens and if it doesnt, I would assume its something to do with the volume dial.

I just started to notice that mine also makes the little humming sound. Kinda annoying

Mine do every once in awhile, but it's never bad or continuous. It just happens when a little fluid gets under the vent.

Mine makes noise so I guess it's normal for this machine my other ones did not make notice

Yes. I do it all the time. It tends to be a tad louder from the plastic parts slightly rattling from the engine vibrations. I hadn't even noticed it until a couple we know joined us one weekend with their trailer and Honda generator.

Ours made the same noises and I just turned to off and then back on again. Now it seems to be ok.

Sounds like you would pull over if you heard it behind you. The sound pulsates fairly rapidly like most other sirens. (Your question makes me think you would probably better off going to store where you can hear for yourself rather than buying online)

I can hear a slight sound on mine, along with the light going off. It seems to take several seconds to reactivate if there is constant movement.

It does but it is very subtle. I used it this morning and I only heard a small peep. Mine at least, doesn't always make much sound. Love it anyway.

Yes, mine also beeps at seemingly nothing. But I think we've been able to narrow it down to high winds. So now we just unplug it when it's windy.

I think mine makes a little noise, but definitely not a lot--sounds like yours may have something wrong with it.

Well, let me qualify my response, not unless the 'appliance' you have plugged in to happens to produce a humming sound. For whatever reason that is. LMAO!

I do NOT recall any such sounds. I use the unit only occasionally, last a few weeks ago.

I hear it also. It doesn't happen as often for me. It's probably just some coil whine and should be fine.

No, my unit does NOT make such a sound. I DO think it is faulty. Please return it, ASAP, but be sure you tell them why.
