Alarm Grid is proud to announce that the Honeywell LTEM-XA and Honeywell LTEM-XV are now available! These are both brand-new cellular communicators for VISTA Systems. They follow the same installation process as the LTE-XA and LTE-XV, which are being phased out in favor of these new models.
What separates the LTEM-XA and the LTEM-XV from their predecessors is that they connect with the advanced LTE Cat M1 networks. These networks allow for stronger security and more effective signal penetration than other LTE cellular networks. The LTEM-XA receives service from the AT&T, while the LTEM-XV is covered by Verizon. As usual, the decision to go with one over the other has nothing to do with your personal phone, and it will have no impact on the cost of your monitoring service.
It should be noted that the older LTE-XA and LTE-XV will still continue to work as intended. Anyone using one of these modules does not need to upgrade to a newer model or replace their existing equipment. In fact, there is very little reason to do so if your system is working as intended. You can confirm that your communicator is receiving a strong cellular signal by checking the Signal LED on the front of the module. A solid green light indicates a strong signal. It's also worth mentioning that the LTE-XA and LTE-XV will continue to remain available for purchase while stock remains of these products. However, there is little reason to buy them, as the LTEM-XA and LTEM-XV are now the recommended models.
One other important note about the LTEM-XA and LTEM-XV is that they offer cellular connectivity only. These are not dual-path communicators, and they do not provide internet connectivity. This is not a huge concern, as LTE Cat M1 service is plenty fast and extremely reliable on its own. But if you do want a dual-path option for your Honeywell VISTA System, then the Honeywell LTE-IA (AT&T LTE & IP) and the Honeywell LTE-IV (Verizon LTE & IP) are still readily available. Just remember that the LTE-IA and the LTE-IV only use "standard" LTE connectivity, as opposed to the LTE Cat M1 service offered by the LTE-XA and LTE-XV. It is currently unknown if Resideo will eventually release dual-path communicators that utilize LTE Cat M1 connectivity. Like always, we promise to keep you informed about any updates.
The function of the LTEM-XA and LTE-XV remains largely the same from other AlarmNet Communicators. By installing and activating one of these modules, your Honeywell VISTA Security System will be able to communicate with the Resideo AlarmNet Servers across a fast and reliable LTE Cat M1 cellular network. If your alarm panel supports Total Connect 2.0, then you will be able to take advantage of that great service as well, provided that access to the TC2 platform is included in your monitoring plan. Remember that a VISTA-15P or VISTA-20P System must have PROM Chip Version of 9.12 or higher to support Total Connect 2.0. We sell PROM Chip Upgrades for the 15P and for the 20P if you need them. Please also refer to this FAQ on identifying and replacing PROM Chips.
While the 15P and 20P are most likely going to be the most commonly used systems with the LTEM-XA and LTEM-XV, you can technically use these communicators with any Honeywell VISTA System that supports ECP mode.
