Firmware Issue Affecting Honeywell LTE-XV and Honeywell LTE-L3V

Posted February 12, 2020 at 09:00 am By Michael Goris

Resideo has discovered that certain Honeywell LTE-XV and Honeywell LTE-L3V Communicators have a firmware issue that makes them unable to appear in AlarmNet360. The affected communicators can still process signals and report to the central station. But these affected units must be replaced.

The Honeywell LTE-XV is a Verizon LTE Communicator for Honeywell VISTA Systems, while the Honeywell LTE-L3V is a Verizon LTE Communicator for Honeywell L3000 Systems. Only certain LTE-XV and LTE-L3V units are affected. The affected units will have a date code ranging from C305 to C365 or from D001 to D023. Modules outside of those listed dates are unaffected.

If you need to locate the date code for your LTE-XV or LTE-L3V, then it is very easy to find. You can locate the code on the inside of the module itself on the lower-left corner of the MAC sticker. Remember, date codes from C305 to C365 and from D001 to D023 may be affected. These date codes are associated with manufacture dates from November 2019 through January 2020.

Additionally, not all units within the aforementioned date codes are affected. If the communicator has a blue dot on the module or on the product packaging, then it is not affected. The images below show units with blue dots on the packaging, meaning they are not affected by the issue.

Keep in mind that these blue dots will also appear on the communicators themselves. Any communicator with a blue dot is unaffected and does not need to be replaced. Remember, this issue only affects LTE-XV and LTE-L3V units. Other AlarmNet Communicators are not affected.

If you have a Honeywell LTE-XV or Honeywell LTE-L3V without a blue dot on the packaging or on the module itself, check for the listed date code to see if your module is affected. More information on this issue can be found in this document provided from Resideo.
