Does the door strike have to be connected to the outdoor unit or can it b connected to the indoor unit? Basically 2 wires instead of 4.

I don't remember but I would not buy this unit if I was you. The reviews don't lie. I bought it, it worked for less than 2 minutes and was broken. When it did work, the quality was very poor. This is a cheaply built piece of junk.

It seems that only one is needed because you only have one door and it's going to close the door automatically in the time frame that you set no matter which button it's mounted near. To be sure, you could go to the official garage butler site and see if they have the answer there.

You would have to install the unit on the floor of the wall and even then you would need an automatic door opener, this system is designed to unlock an electric door strike for a brief period of time so that someone could push/pull open the door without having to unlock the door knob and use that

You would need one for each as you plug the opener into the receiver. Als the receiver is wired to the opener. It has been a while since i installed mine, but i can't see how one would work for two doors.

Yes, that's what I did in my house. I bought two of these, so I had two push buttons and two ringer units. I set one button to ring as "Door # 1" on each ringer unit, and set the second button to ring as "Door # 2". I did that so that if someone comes to either of my exterior doors, I get notified both upstairs and downstairs. You could actually have MORE units than two, as well. Hope that answers your question.

If it is a typical door bell with 2 wires going to the actual push button I would suggest looking for a 2 conductor wire so you do not have to make 2 wire runs. I have purchased and used this in a marine environment but not exposed to the elements. The insulation on the wire is not all that thick.

I bought mine to connect front door bell to either third/second floor intercom. Have not had the chance to connect and try out. I also have to question multiple units for operation. I am truly sorry that I do not have a positive answer to give to you. Joseph B.

Both buttons work on our unit. The outside back door button signal has to go through 3 walls and is 20' away, the outside front door button signal goes through 2 walls and is also 20' away.

The black box is the outside unit. There is a button on the white box when pressed sends a voltage to a connected door latch. You will need to install a door latch made this type of operation.

Mine was the same way. I found a different solution by using a wireless chime. It was a lot of work. I rigged the button to connect to the wired chime. It only worked for one door. Not 2 doors like the extend a chime. But at least it could be heard. Sometimes this stuff doesn't work. What are you going to do?

Thanks, for your question. The ones I purchased from Amazon I had installed by my Son so I could not honestly tell you why one would have 3 wires or two. Now, with that being said my home was built in 1995 so it's not that really old. I cam assuming that depending on how old or new is your home may make a difference. When I see three wire I think positive, negative and ground. A suggestion, you maybe able to connect the negative to the ground making two wires instead of three. Your neighbor if they have the same home chances are they may have change there also so they be of some help also. Good Luck..

The transmitter has to be wired to house door bell. Its not hard to do. Just remove the cover of your door bell. There is probably 3 terminals. One for the front door, one for "common" , and one for the back door. (NOTE: YOU SHOULD POWER DOWN THE CIRCUIT BEFORE ATTEMPTING THE INSTALLATION.) Just loosen the screws and add the transmitter wires to 2 of the terminals. Good luck.

This unit has no place to connect a ground so you have to just leave it out. Unless it's an old metal box which you would connect the ground, but the thermostat itself has/needs no ground. I've used this in two different homes.

The receiver plugs in a regular wall socket. The door sensor works with 1 receiver (bell)

Power input goes into the outdoor unit only. a 4 lead cable (accessory) brings the power to the indoor unit, from the outdoor unit.

I have 2 of these in my house. You install it by wiring it in parallel to our existing garage door button. There's a good guide here (http://www.bornsupercharged.com/tech-shit/controlling-overhead-garage-door-with-z-wave/) that talks about it. Once it is installed you will pair the LFM-20 to whatever z-wave system you currently have then it will allow your z-wave system to control your garage.I believe that button you see is used for pairing the LFM-20 to your z-wave hub. It is recessed since you only need to use it once when you pair.

I have two of these and they both work fine.I have the main wireless unit on the first floor: Heath Zenith SL-6187-C and two of SL-6996-C. So you do know that there is a switch under the little white door that has to match the main unit exactly, right? That is all it took for me to get this to work.
