I bought a new house last month, and I inherited a newer ADT monitored system. I do not want ADT to monitor the system.

Using the collective knowledge of this site, I was able to learn a tremendous amount about how to get the installer code, reprogram the pager to put my cell phone number in etc. The problem I now have is that I am not sure if the alarm system can send out a phone call.

The previous owner did not have a land line. They only used cell phone, and hence the existing ADT Safewatch Pro 3000EN (rebranded Vista 20p) is connected to a DSC? cellphone or wireless box as well as another box which seems to look like a router with an ethernet cable coming out of it going to a plug that must use WIFI through the electric outlets?

I do have a land line, but I would prefer not to have to put new wiring in as I am not that knowledgeable. Obviously, I could figure it out as I see that I would simply have to wire the four cables into the 18 inch beige box, but I would prefer not to do so.

 

Welcome to the forums.

Mr Ron is away and I'm filling in. You'll need to connect an actual phone line to the panel. The GSM/Ethernet module will only connect you directly to ADT. The following two threads can be of some help.

They may have been using some type of IP communicator. Name and model off of the existing devices will make it easier to tell what you have to work with.

Most cell and ip communicators are dealer specific and can't be used for generic communication. Your system may have been pre-wired for landline, but it was never connected.
