Does it also "beep" when detecting voltage ?

Can't answer that, it has not worked since it arrived. I should not have bought this cheap version.

Hi, yes, there is a beep when settings are changed. When changing the thermostat setting w/remote, yes.

No. There is one short very high pitched beep at the end of the timer period. Hard to hear and only occurs once. Better to use an external timer.

It makes a "beep, beep, beep" when it is first plugged in as part of the self calibration but otherwise it makes no noise at all until the low voltage is detected then it alarms as designed.

No, it doesn't beep. And, unfortunately, it doesn't shut itself off if left on by mistake.

Yes, it will beep multiple times when the timer runs out until you turn it off or turn it so the zero is facing up.

No, it beep only when it reach preset temp. Preset that the fabricant decide! I bought this for maple syrop, and the alarm is useless... I use it like a simple digital thermo... without alarm!

No, it does not and neither does it beep. The only annoying thing that I notice is the buttons for temperature adjustment are a little hard to push,and they make a clicking noise.

Yes. It beeps. Plus it beeps faster (and blinks faster) with a stronger field. The adjustment for sensitivity is also better than other comparably priced brands. The other brands I tried had poor sensitivity, and some with push button on, you basically could not tell it they were even on half the time. The GreenLee GT-16 is the best one of several I tried. And I use it often.

No, but a little message comes up on the screen to let you know it's on or off. You can also make it "beep."

Nope no beep. And the collars stop holding a charge after 6 months. One collar only lasted 8 months before it stopped working.Vibrate lasted way too long and the zap only made my boxer twitch his ear

Frankly, I have never heard mine "beep"! I use virtually none of the functions except the H.R. monitor, so I don't know if any other uses would produce a "beep".

No.... there is no alert such as a beep or whistle.............but there is a light on the on lever that comes on when you turn it on and goes out when the water is ready. You can also tell by the sound of the water boiling in the pot when it is ready the boiling noise stops. Hope this helps.

It beeps every time you release the switch botton. Then it shows "hold" so you can see the reading for a few seconds.

Yes it does. It beeps once about every minute until you open the door. I don't know for sure but don't see a way to turn off this feature.

It will only do that if it isn't fully charged. If it continues, you got a lemon. Mine beeps if the power goes off or if I use it before it recharges if I happen to leave it on for a while during a power outage.

No. It doesn't beep when it turns on or off. Just saw someone else's answer. If it does beep it isn't very loud...I have never heard it.
