Can I Update the Firmware On a Honeywell L5210, L7000 Alarm System?

Yes, you can update the firmware on a Honeywell L5210 or L7000 Alarm System. However, you will need a Honeywell LYNXTOUCH-MSD Firmware Updater Tool to successfully perform the upgrade. It is no longer possible to push down an automatic over-the-air (OTA) firmware update to these panels.

Performing a firmware update on a Honeywell LYNX Touch System is necessary for unlocking certain features and functions for the system. You may need to update the firmware to use a newer communicator or to fix various bugs and problems. That is why keeping your system on the latest firmware is very important.

By purchasing the Honeywell LYNXTOUCH-MSD Firmware Updater Tool, you will be able to conveniently update the firmware on your L5210 or L7000 whenever a new update comes available. The LYNXTOUCH-MSD uses a micro-SD card that has the latest firmware installed. If a new firmware version is released, you can first apply the update to the LYNXTOUCH-MSD and its micro-SD card. Then you will apply it to the L5210 or L7000 System.

In the past, it was possible to update the firmware on an L5210 or L7000 by pushing an OTA firmware update down to the panel from the AlarmNet Servers. This made it possible to update the firmware without the use of an updater tool. However, the downside was that OTA updates would regularly fail, and the process would need to be repeated. Performing OTA updates was also very time-consuming.

The new LYNXTOUCH-MSD performs firmware updates faster and more reliably than OTA updates. As a result, Resideo decided to make OTA updates no longer possible for these systems. Fortunately, the LYNXTOUCH-MSD is very affordable, and it provides a long-term solution for updating the firmware on a LYNX Touch System.

Please note that the LYNXTOUCH-MSD uses the same slot as the L5100-WIFI Card. If you have this module installed, you must remove it before performing the upgrade. The panel should be powered down before doing this. For more information on using a LYNXTOUCH-MSD Firmware Updater Tool, please check this FAQ.
