Honeywell LTE-L3A Posts

Resideo Technologies has announced an automatic firmware update rollout for several AlarmNet LTE communicators used in security systems. These updates are designed to enhance cellular connectivity and ensure a more stable, reliable link between your system and the AlarmNet cellular network.

According to MyWebTech Technical Notification #136, Resideo will begin pushing firmware updates over the air within the next 30 days to select radios used in burglary and residential fire applications. These updates are part of an ongoing effort to maintain optimal performance and address prior cellular connectivity issues.

Affected Radios & Latest Firmware Versions

• Honeywell Home LTE-IV — Firmware 4.1.31.0
• Honeywell Home LTE-IA — Firmware 4.1.31.0
• Honeywell Home LTE-XV — Firmware 4.0.62.0
• Honeywell Home LTE-XA — Firmware 4.0.62.0
• Honeywell Home LTE-L3V — Firmware 4.0.54.0
• Honeywell Home LTE-L3A — Firmware 4.0.54.0
• Honeywell Home LTE-HSV — Firmware 2.14.16

Many of the affected communicators, though still active in the field, have been discontinued by Resideo and AlarmNet. Because they are no longer offered by Alarm Grid, discontinued products are not linked above.

These updates will occur automatically, and no action is required from end users in most cases. However, communicators with low backup battery voltage, or with a missing backup battery, may not successfully complete the update. In those instances, the communicator battery should be replaced so that the update can occur.

A small number of systems may briefly display a “radio trouble” condition when the communicator reboots after the update. This condition can typically be cleared by entering a valid user code + 1 (Off) twice on the system keypad.

Notes on Fire Radios

The same technical notice also reminds users about firmware updates for certain commercial fire communicators (HWF2V-COM, HWF2A-COM, LTE-CFV, LTE-CFA). However, Alarm Grid does not support commercial fire alarm systems, and these devices are not sold or supported by us. If you work with fire alarm communicators, contact your fire system provider or Resideo technical support for further assistance.

Summary

Resideo’s automatic update process ensures continued reliability for AlarmNet-connected communicators. As long as your communicator is in good working order and has adequate power and a good backup battery, it is likely that no action will be required on your part. With a possible exception of a disarm command to clear a communicator trouble display on some VISTA systems.

Alarm Grid will continue to keep you informed of any further changes that may affect system performance or connectivity.

Resideo is currently in the process of pushing automatic OTA firmware updates to all active AT&T LTE Communicators. The updating process is ongoing, and we are not sure how long it will last. You should not notice any changes to your monitoring service or your Total Connect 2.0 account.

If you recall a few months ago, we announced that Resideo was pushing down automatic over-the-air (OTA) firmware updates to LTE communicators. Resideo started with the Verizon LTE Communicators, and now they are updating the AT&T LTE Communicators. This is a very similar update with no major differences.

Just like before, Resideo is expected to perform this update cycle in batches. Units that were registered first will have the update performed first. This will continue in sequential order until all active Resideo AT&T LTE Communicators have been updated. Any new AT&T LTE Communicator activated during this time will be placed at the end of the queue. If an update fails, that communicator will be pushed to the next batch to try again.

Remember, the communicator must be active and connected with the AlarmNet360 Servers in order for the update to go through. Any communicator that is not active will not be able to receive the update. This includes any communicator installed inside a panel that is currently powered off. Try and keep your panel powered on at all times to ensure that the update can go through successfully.

The following Resideo Communicators are affected by this update:

• Honeywell LYRICLTE-A for Lyric Controller
• Honeywell LTE-L57A for L5210 and L7000
• Honeywell LTE-IA for VISTA Panels
• Honeywell LTE-XA for VISTA Panels
• Honeywell LTE-L3A for L3000

It is possible that your panel may reboot as part of the updating process. However, you should not notice any other changes. Additionally, the following Contact ID messages may be generated during the process:

If you have any questions regarding this update, please do not hesitate to email us at support@alarmgrid.com. Remember that our support hours are from 9am to 8pm ET M-F. We look forward to hearing from you and answering your questions!

Resideo will be pushing down an over-the-air (OTA) firmware update for all AlarmNet LTE Communicators later this month. This update will go through automatically, and it should not affect your monitoring service in any fashion. The update will be applied sometime later this month.

This update only affects the communicator, not the panel itself. The updates will be applied automatically in batches until it has been applied to every Resideo LTE Communicator. First the Verizon LTE Radios will be updated, followed by the AT&T LTE Radios. Resideo will start each update cycle with batches of units that were registered first. The company will follow a sequential order, finishing with batches of units that were registered last. Any new unit that is activated will be placed at the end of the cycle.

It is possible that your system may reboot as part of this update process. However, it should resume normal operation after the update is complete. Additionally, you may notice the following contact ID codes in your Event Log on Total Connect 2.0:

Resideo says that this update will allow their LTE communicators to interact more effectively with the cellular network. Users should expect this update to go through sometime later this month. We do not have an exact date as to when the update process will begin. If you have any questions about this update, please contact us at support@alarmgrid.com for more information.
