Resideo Communication Failure Update – LTE-CFV, HWF2V-COM, LTE-IV, LTE-L3V, VISTA-21IPLTE

Resideo has discovered an anomaly that can lead to a communication failure in the following communicators: LTE-CFV, HWF2V-COM, LTE-IV, LTE-L3V, Vista-21IPLTE

This anomaly may cause the SIM card in the device to become locked and may lead to reports of communication failures. We have reports that certain communicators may have experienced this issue between March 19 and March 28, 2022.  Additionally, devices that are set to 30-day check in that are not communicating can be confirmed with your sales representative (even if you have not yet received a communication failure message). 

Devices that are set up using IP and Cellular paths may have reported a secondary path failure instead of a communications failure.  Once the issue occurs with a communicator, it will not recommence communications absent you are following the procedures below.

Resideo’s AlarmNet 360 has reported communication failures as identified on the chart above.

How to determine if your device is affected?

Devices that are affected by this anomaly will show the following symptoms:

A. Locally on the device:

LEDs on the device will flash regularly at a rate of two times per second.

B. On AlarmNet 360:

Devices performed normal check in procedures (QOS) for a period leading up to March 19, 2022.  Beginning on March 19 through March 28, 2022, certain units stopped communicating and reported a communication failure as identified on the chart above. 

Correction procedures?

Devices that are affected by this issue must be corrected by replacing the SIM card.  SIM cards will be available to order using the SKU SIMKITV beginning on April 7 as needed.  Customers may also contact the GeoArm or Resideo Sales (800-645-7492) team to arrange for shipment of SIMs .

Procedures for replacing the SIMS will be included in the SIMKITV, we have also posted the procedures at this link: SIM Card Replacement

Resideo is confident that the anomaly that led to this issue is corrected and will not occur again after replacing the SIM Card.

Alarm.com Announces it will still support GE Interlogix!

As you all know United Technologies announced that Interlogix after all these years is closing their doors at the end of 2019. Alarm.com a few days later sent us a confirmation email that they would still provide Alarm.com compatible communications devices for monitoring abilities. In addition, Alarm.com announced it will continue to support the product lines for dealer tech support.

This is big news for anyone who has an Interlogix such as a Concord, NX Series or Simon security system. This news confirms that the Interlogix systems life span has been extended at least up until LTE cellular modules are phased out. After LTE cellular communicators are phased out well down the line we are not sure what will happen from there or what communication modules will support the monitoring of Interlogix!

What we do know is that end-users that have Interlogix will still be able to enjoy Alarm.com monitoring services, remote app control with the Alarm.com interactive app, Z-Wave home automation control, Amazon Alexa / Google Home / Apple Siri voice control and Alarm.com compatible IP security camera abilities for quite some time.

Here is an example email that Alarm.com is sending to its dealer’s.

United Technologies recently announced that they are winding down their Interlogix security business in the U.S. and Canada, but they will continue to manufacture and sell through the end of the year.

Alarm.com will continue to support all Interlogix panels currently installed, as well as all new installations going forward. Our services will continue to work seamlessly on the lineup of Interlogix panels we support, now and into the future. Also, we will continue to manufacture Interlogix LTE upgrade modules.
