Upgrading a Honeywell Lyric to Use LTE

In this video, Michael from Alarm Grid explains how to upgrade a Honeywell Lyric Controller to use LTE cellular communication. The Lyric Alarm System has built-in WIFI, but if you want to use cellular connectivity, then you must add a cellular communicator. You need to make sure to get an LTE cellular communicator, because old 3G and CDMA communicators can no longer be activated for monitoring service.Show more

The Lyric uses WIFI and/or cellular connectivity to communicate with the Resideo AlarmNet Servers. When an important system event occurs, such as a burglary or fire alarm, the Lyric will send the signal to AlarmNet. From there, the notification is forwarded to a central monitoring station and/or the end user directly, depending on the user's monitoring plan. Since the Lyric can already communicate with AlarmNet via WIFI, cellular communication is optional. But there are still some good reasons to consider adding a cellular communicator and making the Lyric System dual-path with both WIFI and cellular.

When compared with WIFI, cellular communication is more reliable. It is unaffected by power outages, and a strong cellular signal will almost never go down or become unavailable. While internet outages are fairly common, a cellular connection will almost never go down or become unavailable. Additionally, many users simply feel comforted in knowing that their system has multiple communication paths available.

If you do decide to add a cellular communicator to your Lyric System, then the modules to consider are the Honeywell LYRICLTE-A and the Honeywell LYRICLTE-V. Both units accomplish the same end result. But the LYRICLTE-A communicates across the AT&T LTE Network, while the LYRICLTE-V communicates across the Verizon LTE Network. We recommend going with whichever network works best in the area where the system will be used. Keep in mind that you will need a cellular monitoring plan to activate a cellular communicator for monitoring service.
