Tried to upload a photo of the adapter and remote. Basically, this unit has a few purposes but I’m using it as a range extender for one door. I had to buy an extra remote, the adapter and some bell wire.
The extra remote is because this unit uses the newer rolling code technology vs the older rolling code system that my original door opener uses.if you’re current opener has the yellow learn button, you should be able to just relearn your existing remote to this unit instead of your opener. I bought a 3 button keychain sized remote in case I need it for more than just one door in the future but only installed this on the one door where I was having interference, no need running wire where it wasn’t necessary for me.
Think of this as just another wall button to make the installation easier to visualize. All this does is connect to the same connector as your wall button. When you activate this/ hit the remote, it sends a pulse and tells the door to open/close just like a wall button. I just twisted it onto the same wires and then pushed them back in. There are a bunch of ‘contacts’ on this unit for various functions. They really advertise this thing as a commercial application with the ability to open/close and then stop doors at certain heights, etc.
But The other function is to just have the open/close work for 3 doors - see the photo with connectors and separate learn buttons for three doors - and it really extends the range.
You just run the bell wire from the contacts to your garage door. And it is low voltage so if it doesn’t work, you just swap the +/- and try the wires the other way. You can do this for all three of your doors if you’d like.
Then you program the remote(s) to this unit and THEN you program HomeLink using the newly programmed remote and learn button on this unit. Like an idiot, I was trying to program using the new remote and the learn button on my old opener and couldn’t figure out why I was having issues until I realized my error. Once I used the new remote and the learn button on the extender it worked like a charm. Total operator error.
All this unit really does is become an outside of the opener, new receiver unit for your garage door opener(s). I only needed it for one door but you can centrally locate it and connect it to three doors since it has enough contacts and learn buttons for all 3. It’s pretty easy. This is also a good replacements if your opener is working well but your receiver unit is broken inside the unit. This is much cheaper than a repair/replacement of the whole opener.
For the adapter, I would get the one listed in the photo. I think it’s the 85LM. It is just a barrel plug in ‘normal’ adapter. To me, it was just easier than than having to connect a few more wires but I think the other option is good if you don’t have an open outlet nearby and need a longer power run. You should be able to find the other model with a search if you need it.
As an FYI on the functionality - my original rolling code opener from 13 years ago has a purple learn button, This one has a yellow learn button so if you need a new remote(s) make sure you match up the correct technology for the correct learn button and get one for the yellow learn button. And then when you press the learn button for homelink, press the learn button on this unit NOT your opener. Each set of contacts has its own learn button. If you zoom in on the the attached photo or go to Amazon and zoom in on their picture you’ll see the learn buttons and contacts where you connect the wires. You can look up the directions online pretty easily as well but it’s a simple connect. Takes 5 minutes.
Range has been extended DRAMATICALLY and no more interference on that one door. I didn’t bother installing to the others since they work fine but the process is the same - and it’s easy.
Hope that helps!
