No it stops after about a minute and remains armed. I dont regret buying it. Ofcourse is not a $200 system works just fine. Pretty loud!

if the person lifts up to turn, it will go off, but normally shuts right off. I have not experienced false alarms. This was very beneficial to us.

The batteries will last approximately two years when in standby mode. If the alarm is sounding continuously, the batteries will last approximately five hours. With normal use the alarm will not constantly be in standby mode or sounding continuously. Therefore, the user can expect the batteries to last anywhere from 3-12 months depending on how often the alarm is activated.

Apparently not. The alarm seems to activate only when the temperature is above the set point.

It depends on your surrounding ambient noise. We did hear ours going off in the basement from the upstairs and the other side of the house, but we didn't have much other noise on at the time. If we'd had the TV on, we probably wouldn't have heard it right away. If you change out the batteries For these when you do your smoke detectors, then it should sound the alarm for at least a day before losing power. Should be enough time for you to hear it when the house is quiet, like bedtime.

From my experience it will go off with almost any movement. Even a strong wind blowing against the window will set the alarm off.

Yes. On radio and mem-card playing there is no interruption when the plug is pulled. I have not tried anything like the alarm function but I doubt there would be a problem. I keep my radio loaded with rechargeable batteries just in case there is a power failure. Check you battery connections regularly as the contact tends to bend and leave the battery floating without making contact.

No unless you want it to dial out when set off. If you want it as a alert when a door is opened or a window works perfect. I got it to keep my teenager from sneaking out havnt had a problem since.

I have never experienced a false alarm. The unit has a low battery light to tell you when it is time to change the battery. I have used my unit since 10/27/11 and have not needed to install a battery yet. I personally think it is a tremendous value for the money!

if you touch the alarm when it's on it will go off and will scare the crap out of the theif before he can turn it off it is very loud. i have placed it to where it can't be seen so there is no chance of anyone turning it off with out alerting me.

Yes, the alarm continues to sound until you acknowledge. However, be careful to re-enable the alarm when the temperature is restored.

No. If chime is turned on, the control panel will beep. If the alarm is armed then the siren will go off. But the contact itself makes no sound.

The unit has a battery in case you lose electric power, but they are also connected to your house's electric wiring so the battery doesn't need to be replaced so often. In addition, when one smoke alarm goes off, all the smoke alarms in the house go off. This is important as I have a smoke alarm in the basement that I might not hear from some of the bedrooms if they all didn't go off together.

Yes, the alarm is AC power. The battery is only meant for the possibility of a power outage. The battery only last for the 36 hours after the alarm is triggered, but I don't know how long the battery last if it is not sounding. Since there is only pull on the battery after the trigger, I am guessing that the length of the battery life is as long the battery itself. I have one more thing to tell you. This thing is pretty loud when it goes off if you haven't heard it yet, so you'd definately be able to hear it...probably in your neighbors basement!If you have anymore questions, don't hesitate.

When the batteries run down, the alarm will go off continuously to let you know the batteries need to be replaced.

Sensors are always on. The master unit/receiver (alarm) can be muted. You would have to remove the sensor from the window, or door, (thus triggering the alarm) to remove the battery. Best to keep master unit in your bedroom. I have a sensor on my back door AND my daughter's window. You can set different beep quantities for the different sensors.

There is a remote that you place in the house and yes that will go off along with the alarm on the unit.no it can not be remotely turned off. I don't thin any of the alarms can. Its part of the code so you have to go look at why the alarm went off.
