Any false alarms, white it is hanging on door, because of unit itself ?

Yes, a few times the alarm has activated;even with new batterys.it sent me on a "search" but it likely was triggered by small vibes from who knows where or possibly air moving between the door and door frame,as that is where I had the alarm placed.All in all, for the price,it is well worth the purchase in my opinion.

I had no problems with false alarms. I suppose if it was on a door that was very loose in its frame or a gate that might sway in the wind, it is possible. For a typical home/apartment type door, there should be no problem. The only issue I had was not being able to turn it off, without triggering it briefly.

No, I have had no problem with false alarms. I am very satisfied with this economical product.

Yes. Sometimes the vibrations from closing another door or dropping something set off the alarm

It's been aawhile since I configured and installed my system but I'm pretty sure there were hidden door sensors. Mounted in the jam I believe.

My unit shuts off autatically if I leave it on. Also I'm not aware of any alarm to indicate a full filter.

Just turn it so the zero is facing up. The alarm should stop when you do that

The little door can stay on or off. If its off the detection angle will become wider causing the unit to be tripped at a wider peripheral.

Happened to me at 1 am a few times! It is alarm. I don't have it handy or I could give more details. The instruction sheet should help you out though. Good luck :)

No. All you see are green dashes showing it is working the way it should. You can test it and the alarm is very loud so you would certainly hear it no matter where you are in the house.

It is a magnetic door alarm. You attach 1 side to the door, and the other to the door frame. When the connection is broken the device alarm sounds.

I lined it up, opened the door. When the alarm went off, I took the backing off and stuck it permanently. It works perfectly. Someone opened my door one night and I heard the alarm from upstairs. The intruder left promptly. Also, it alerts when children leave or enter the house, or leave the door open.

Just make sure you hide it properly. The element of surprise will usually catch a person and move away. There's a magnet on the alarm it sticks pretty good if not use those gray packing tape.

Hi,They are showing the door open on the photograph. It's a weird photo and in no way representative of the way the unit looks in real life. I have one of these and an extremely happy so far. We have had it since March. Good luck!

The contact could only be mounted to one door which would leave the other with no alarm. Unless, you mounted the the whole alarm unit. To one door and the contact to the other door. That wouldn't look good.

There is a setting to reverse the sensor status. Out of the box it said the door was closed when open, etc
