What happens to the door opening and shutting when the power goes out??? Is it controlled by the magnet only?

Its an electromagnetic switch powered by a 9 volt battery. Pet wears a magnetic key witch triggers the switch to unlock.

This was the worst purchase I've ever made. The door hasn't worked since I purchased it. After many attempts to contact the company they said they would consider a refund if they decided something was wrong with it and I would have to pay for shipping both ways. I ended up just leaving it in and using white duct tape across the bottom to keep it closed. I will never buy anything from this company again. Read the customer reviews mine is there along with others who have had their own dealings with this company. Hope this helps. Good luck.

It's battery operated. But don't worry, it doesn't work with batteries, either.

I have this model door closer and it closes perfectly - complete closes, quietly and quickly, with a soft close. Ours does not keep the door open, but I do not know if it has the ability to do so.

That is correct. It works with a magnet when you open the door it pulls a string that when releases hits the bell.

There is a plunger on the back (opposite end of the bulb) that pushes in when the door is closed. Same as a refrigerator interior light. Great item!

It closes pretty well...it has a magnetic closer on both doors....you could also rubberband the doorknobs together to keep a young child from opening them. Hope this helps

When the magnetic connection between the two parts of this sensor is broken, your alarm system will register an open condition. I guess if the window or door is struck in such a way that would cause the sensor parts to move enough to break the magnetic contact it might trigger the alarm. However, I think they were only meant to register open or closed.

I was told by Sentry if the lock fails, call a locksmith to cut the door off. Probably the same if electronics melt. I suggest U call Sentry

If it is making constant contact, thus allowing constant voltage on your opener from a full time closed loop instead of a momentary pulse, which it should be doing, then yes it will keep the opener in one position. It is an override for the safety sensors at the bottom of the door. If the sensors fail, the only way to close the door is to stand there and hold the button down until the door is fully closed. If this is not the first time you have had to change the button, then I would guess that you have a short in the wire, most commonly caused by a staple shorting the two wires together somewhere between the button and the opener.

It is not magnetic, it is mechanical in operation. The stop lever has two tabs that engage to hold the stop button closed. So the power will be off if the power is disconnected.

it comes in the "closed" position. What this does it stretch out as it "opens" and then holds it there. This won't pull your door closed, instead it holds it open and resists the closing.

It is limited by the timer you use. When power to the motor comes on the door opens or closes depending on what position it is in ( if closed it will open, if open it will close). So as many times as you can set the timer to turn on and turn off is the maximum number of times it will open and close. For example mine is set to close at 7 pm and open at 6 am. If I manually open the door before 6 am, it will close at 6am and stay closed till 7 pm unless I manually open before then, if I close the door before 7pm it will open at 7pm.

Not sure I understand what you mean by "if I open using the knob it autocloses." Do you mean if you turn the dial to unlock the lock manually, it will then relock automatically? That's weird. If I manually unlock mine, it doesn't auto relock unless I open the door and then shut it again so the magnet triggers the relock. And if the open/close button does nothing, it sounds like maybe you got a defective unit.

the key is not needed to open and close the unit. it uses a magnetic push mechanism. so, you just push in on the door and the magnet releases and the door opens. to close, just push on the door and the magnet is engaged.

It's like any door knob lock. If you shut it in the open position, you won't be locked out. You can shut it in the locked position also. It's actually an interior knob for bedrooms and baths. It has the little hole on the outside that you can pick to open it if you accidentally get locked out. It replaced a knob that was on my son's door for 14 years. I had to pick it so many times when he was younger that it finally broke. LOL I have a different kind on my front door. You have to use the key to open it if it's locked. We leave the key in it. If we want to go out, we just turn the key to open it. You can't get locked out. It will stay unlocked until you turn the key again from the inside to the lock position. It's not a knob, but has a handle. It's the kind you use your thumb to depress it and push. LOL, sometimes I forget to lock it back, but I live in a very rural area.

This item is not spring operated. It is simply held in place by the magnet. I am not in this property often but I remember the door seems to be in the same position as a standard stop. Appx. 3". Hope this helps.

It does not. When closed, it is held shut by some fairly weak magnets, but when open, does not do any sort of locking.

Mine doesn't automatically shut. You have to lift and close the gate door each time. It will stay open if you open it.
