Can you add another indoor unit unit for a total of 2 units wired together so both indoor rooms can communicate with the outside unit?

Unsure of answer. But our unit broke down in less than a year so not much of a fan of the system.

Will have to change speakers to ones that are double the impedance of those coming with the 121, with that volume at/from the remote units will be "less"

I believe that the two units must share a common ground, Most homes are wired this way. Our units worked well from one end of our house to the other.

I don see why not, it is essentially like having another phone jack installed on the same line, much like you can have a phone jack in each room of your home all on the same line

No. You can buy an additional piece so they don't all 4 have to be wired to the unit though. Either way I wouldn't recommend this model.

While we've not had the occasion to do this, it shouldn't be a problem. The wires connect by just pushing into the unit and plugging the unit in. If you have the wiring at the second location, you should be good to go.

Yes you can, however my unit seems to forget what was set into it. In my opinion these newer units are less reliable than the older units I have.

Hello J, I bought it in a pair. Make sure you have access to the same electric circuit in the rooms you want to connect. In case you have three-phase electric network, chances are some areas are served by different phases, in which case your powerline is not an option. Good luck, Sergio Bergson

yes you can wire them witha swith. there is a switch on the unit but just leave that switch on and you can run another wall swith

Hi BMcDuffey. Yes, you may use more than one Powerline device and install them in different rooms. Just make sure that it will be on the same electrical circuit with that one being used by the router.

Yes, that is called daisy-chaining. We recommend that you do not do more than two unit though as the network speed will decrease with every unit you add to the chain.

Yes, if you have 2 units, you pair them with each other and just talk to each other that way. That's primarily how we use them.

I have not tried this configuration, but, this product acts like an ethernet cable using your home power. As long as the units identify themselves to each other, I think it might work.

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.

I have three units. Two of them are in the house, the 3rd in my office above a detached garage. Two most distant unit are about 150' apart ... works great for two/three way communication.

These intercoms require that both buildings' electrical systems be tied together. My recommendation is to use walkie-talkies. That is the solution I chose for a similar problem.

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.

Yes, you can. We had two units for a long time together. They didn't interfere right away with each other. I think we have someone that moved into our neighborhood that has another unit that is interfering with ours. We just purchased a new unit this week actually to replace one of ours in our set of Mobi's. The one that we replaced also was having battery issues. It would barely hold a charge for more than a few hours. :( The second unit is still running strong though!
