It would stop as soon as you close the door it sounds off when it doesn't detect the sensor.

It you wish to use the alarm when you leave the house, you need to change the setting on the side of the alarm from (Home) to ( Leave) setting. This will allow you 45 seconds for you enter the code to get the door closed. When you return you will have only 30 seconds to re-enter the code before the alarm will sound after opening the door. Hope this information helps.

If I unplug the unit, the alarm goes activates. If I plug it back in, the alarm goes off. Hope this helps.

There is a switch on the side of the alarm to turn it off. It will go off when you open the door. It is very sensitive and even a heavy truck going by our house on the road will set it off. I have another alarm that might suit your purpose better that I use. It is a GE 45117 and it has a key pad on the unit. You set your own code. If the door is opened it will go off and it has an ear-splitting screech on that baby. You can put this on the outside of your door, it comes with removable adhesive. You could use the Techko on the inside while you are sleeping. This one just hangs on the door knob. Just a thought. There is a switch on the side of the alarm to turn it off.

Does not work with an on or off switch. It has a 2 pronged extension that fits between the door and door frame. When it is set the prongs are together, but when door is opened the prongs separate and the alarm goes off. To set you pull the prongs out of main unit and place in between door and door frame and it is set. Sounds like a legitimate alarm and somewhat loud. I am happy with the product.

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.

Since the reason the alarm goes off is that the "connection" is opened I don't see what difference it would make if the window opened in or out. It works like two magnets...when they are touching the alarm is silent, when they are "opened" or separated then the alarm goes off. Very loud!!! Friend put one on door on his boat, forgot about it, went out weeks later and scared HIMSELF when the alarm went off!! You can turn it off when you don't need it. Installs easily, takes about 2 minutes. Hope this helps.

It is very loud but it alarms near the bed the person is in. We used it for my Dad who was not supposed to get out of bed but didn't understand it. What I did was put a baby monitor next to the alarm in the bedroom so I could hear it in another room and then would run in and try to get there before he actually got up. The alarm also tends to go off when the person is just turning over or sitting up in bed.... there are a lot of false alarms. It's not ideal but it's better than not having it. Hope this helps.

I can see your point about turning it off. I have a cheaper unit that I keep in my shop. Thinking about upgrading. I just turn the sensor toward the wall when I'm working out there so the alarm will not be sounding constantly all day when I'm out cleaning or working. Kind of like telling the guard "don't shoot! It's me! Just take the afternoon off"! I just have to turn it back around when I lock up. Form a habit like pulling your keys out of the door after you lock the lock. It's just habit.

You have to move it for the alarm to trigger. Opening the door won't do it, but closing it will. You can adjust how sensitive it is, and how long it takes to arm after turning the key. So if you move it, it will start beeping and if you don't disarm it, it will trigger the alarm. Don't know how long the 9V battery lasts, because I just got mine a few weeks ago.

If once you lock the trailer there won't be any chance of it accidentally going off, I'd say this is a good application. The only thing that I think about is what I would do at home. I wouldn't leave it directly in front of my front door, as the mailman puts mail through the slot. I wouldn't want that to accidentally set off the alarm (it IS loud!). But if you have a good spot for it in your trailer, this should work.

It will not go off unless you pull the trip cord. It's like a Hand Grenade. If you had the string hanging on the outside of your bag around your wrist and someone grabbed your bag then yes, it would go off inside the bag. I think better to have the alarm cord on your arm and if someone messes with you pull it and toss the alarm. It will continue to sound for one hour so that if you were knocked down the perp couldn't just stop the noise if you threw it out of reach. Well worth the small price for this much attention. Also, it would be comforting to someone to place one by the bedside if you hear something you could pull the cord and get that screaming alarm. It will not go off unless you pull the trip cord.

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.

The easiest answer is to buy some extra presence sensors. Then when they are detected you can have the home disarm. For example, I keep one on my keychain (mostly because from your phone you can make the presence sensors beep to find it) and one in the glove box of my car. When my keys and car are both gone, it activates away mode which arms the alarm and locks any doors that i left unlocked. It also turns off all the lights in the house. When the sensors are detected again, the alarm disarms and the door coming in from the garage unlocks, and the system is changed back to either night or home depending on the time of day. Does this answer your question? As an added bonus, you'll be able to check the app on your phone to see who is home.

Hi! No, unless that door was never opened. The alarm would go off anytime you closed the door, so unless you're just protecting that door and not using it--I wouldn't buy it for that purpose.

I've had these for years. If one alarm senses smoke they all go off but will report the name of the alarm location, such as "Kitchen". To silence all alarms I believe you must silence the one in that location. This makes sense as you'd want to check that location. The other alarms will silence after a few seconds. I'm not sure if hitting the silence button on a different alarm will silence them all or just that remote location as the only times they've gone off I've just run to the one that is triggering the alarm. I think this has happened only in our kitchen and we're usually right there cooking when that has happened. I've had these for years.

You set the alarm to sound for a certain amount of time(for my mother I set it to stay on for 1 hr). After the hour is up the door stays open until the next alarm goes off. For my mother we had 3 alarms that went off in the course of a day.
