With a Honeywell VISTA Panel, a communicator is required to get the system up and running for alarm monitoring service. The ADC-SEM210-VT-AT is a special communicator, that allows a VISTA to work with the platform. The module provides dual-path connectivity across cellular and IP.

In the past, Honeywell and Resideo Alarm Panels were restricted to using the Total Connect 2.0 platform for interactive monitoring. But started releasing System Enhancement Modules (SEMs) that allow these panels to access the platform instead. There really isn't much of a difference between ADC and TC2 when you look at their features. But there are some users who want to use the ADC platform, while also having a high-quality system from Resideo. Accessing ADC can be particularly important for users who already own Security Cameras and/or want to take advantage of ADC Video Analytics features. Now there is an effective and easy solution with the ADC-SEM210-VT-AT.

Making sure that your alarm monitoring communicator is dependable is very important. You won't have to worry abut that with the ADC-SEM210-VT-AT. This module actually works across both the AT&T LTE Network and an IP network using a hardwired ethernet connection. If one communication path goes down or becomes unavailable, the other one will still be there to provide backup. This allows you to get the best of both worlds. You get the speed and quickness of an IP communicator, plus the reliability and dependability of the AT&T LTE Network. And since AT&T plans to support LTE communication well into the very distant future, you can expect your ADC-SEM210-VT-AT to keep your VISTA Panel monitored for many years to come. If you don't have strong AT&T service in your area, there are also similar SEM devices that use the Verizon LTE Network or the Telus LTE Network (Canada only). Please note that you will need a Gold Plan or higher from Alarm Grid to unlock the full potential of these communication modules.

The ADC-SEM210-VT-AT also doubles as a perfectly functional Z-Wave Plus controller. By installing this device and activating it with, you can start creating a robust network of Z-Wave devices. This includes smart peripherals like lights, locks and thermostats. We recommend using Z-Wave Plus devices with the ADC-SEM210-VT-AT, since they offer the best wireless range and battery life. However, you can still use older Z-Wave classic devices if you have any around. Just be aware that all Z-Wave operation and control will need to occur through A VISTA Panel cannot support on-site Z-Wave operation when an SEM device is used as the central hub.

Only VISTA P-Series Panels are compatible with System Enhancement Modules like the ADC-SEM210-VT-AT. This includes the VISTA 10P, 15P, 20P and 21iP Systems. The panel must also be from 2005 or later, and it needs to be running firmware version 3.1 or higher. You can determine this information by checking the system's PROM Chip. The PROM Chip is a small black chip found on the main circuit board. This chip has a white sticker with a code that begins with "WA". Using this code, you can determine if your system can support an SEM device. Keep in mind that certain branded equivalents of VISTA Panels, like the First Alert FA16CPS can also support SEM devices.
