The Honeywell LYNXTOUCH-MSD is the firmware updater tool for the LYNX Touch L5200, L5210 and L7000 Systems. By using this convenient device, you can quickly update the firmware version for your LYNX Touch System. This is necessary for getting your L5210 or L7000 working with an LTE communicator.
There are two LTE communicators available for the L5210 and L7000. The first is the LTE-L57A, which connects with the AT&T LTE Network. In order to use this communicator the panel must be on revision 9.00.209 or higher. The other is the LTE-L57V, which connects with the Verizon LTE Network. In order to use this communicator the panel must be on revision 9.00.201 or higher. Getting your system connected with an LTE network is important for ensuring that your system experiences the fastest and most reliable communication possible. It will also "future-proof" your system, as the LTE networks are expected to be kept in service for many years to come.
Although it was previously possible to push down a firmware update to an L5210 or L7000 over-the-air (OTA), this is no longer the case. Instead, this firmware updater tool is required for anyone who wants to provide a firmware update for their L5210 or L7000 System. The updater tool is easy to use, though it will require that the user accesses the back of their panel to make some hardware configuration changes. Alarm Grid has an FAQ on how to use the module which can be seen here. We also invite you to view the install guide for the module.
Additionally, upgrading to a higher firmware version may unlock new features and functions for your panel as they become available. Updating the firmware can also be necessary for fixing various bugs and problems so that your system functions as reliably as possible. Finally, the newest version of the L5100-WIFI with the MAC prefix B8:2C:A0 requires that the LYNX Touch System is running Firmware Version 8.00.183 or higher. More information on this requirement can be found here. All of this makes getting the firmware updater tool extremely important for anyone with an older model L5210 or L7000 who wants to get the most out of their system.
Note: Alarm Grid has discovered that updating a LYNX Touch Panel to firmware version 9 will prevent the LYNX Touch Panel from working with the Lynx Connect App. Resideo has advised that there will be no fix for this issue. If you wish to have local WIFI app control of your panel, the only option would be to upgrade to a Lyric Alarm Panel, and use the MyHomeController app instead.
Update: As of October 2019, the LYNXTOUCH-MSD Firmware Updater Tool can also be used with the Honeywell L5200 System. Please see this blog post for more information. When an L5200 is updated to version 9.00.xxx, the AlarmNet 360 server will see it as an L5210 from that point forward.
