September 2026 Archives

Resideo has extended AlarmNet360 (AN360) connectivity for the Lyric® security system. This extension runs through June 1, 2028, reversing notices sent out earlier this year that signaled an end to remote Lyric management. Here's what changed, and why an upgrade is still worth planning.

A Quick Timeline

The First Two Notices: TN-140 and TN-142

Resideo's first notice, Technical Notification #140, explained that the legacy authentication process Lyric panels use to connect to AN360 was expiring on April 15, 2026. After that date, AN360 would no longer support adding new Lyric systems, enrolling new sensors, syncing configuration changes, modifying system settings remotely, applying dealer branding, pushing firmware updates over the air, or changing central stations. Core system functionality (arming, disarming, user codes) and connected services (Total Connect, alarm reporting, two-way voice) were not affected.

TN-142 arrived three weeks later and officially superseded TN-140 with more detail. It confirmed that communicator-level settings, like TC2 configuration, comm path, and central station changes, would keep working through AN360 as before. Panel-level settings, like partition and system changes, two-way voice, Home Kit, Lyric Lock, and firmware updates, would instead require USB (firmware update only) or local panel programming. TN-142 also warned that AN360 would automatically disable the Local Programming Lockout and Lyric Lock features on all panels during the week of April 6, 2026.

The Latest Update: TN-150 Restores Support Through 2028

Technical Notification #150, issued September 21, 2026, explained that the root cause of these changes was an expired security certificate with Resideo's certificate provider. While alarm routing continued working throughout, remote capabilities like configuration changes, sensor additions, and device replacements were no longer available.

Resideo has now secured an extension with the certificate provider, restoring full AN360 remote management for Lyric systems through June 1, 2028. TN-150 officially replaces TN-140, and no immediate action is required on your part.

Can You Still Activate a New Lyric System?

We're not sure yet whether a brand new, previously unregistered Lyric panel can currently be activated on AN360. In theory, the answer is yes. We want to confirm the current activation process ourselves before telling you it's a 100% safe bet. We'll update this post as soon as we know more.

UPDATE 09/25/26: We have confirmed that it is possible to activate a new, previously unregistered Lyric. However, we still firmly believe it's time to begin planning your system upgrade. Don't wait until the last minute and get caught up in a backlog of users trying to upgrade.

It's Still Time to Plan Your Upgrade

Even with support extended, June 2028 isn't that far off. If you're running a Lyric system today, now is a good time to start planning a move to a newer platform. Alarm Grid recommends the PROA7 or PROA7PLUS when you're ready to upgrade.

Both of these panels work with the full line of SIX Series wireless sensors right out of the box, so much of what you already own will likely carry over. If your Lyric setup uses older 5800 Series sensors instead, you'll need to add a PROTAKEOVER module along with the Pro Series panel.

2GIG released Firmware Version 1.2 for the GC Touch security panel in August 2026. This update adds new chime options, additional Dark Mode options, and the ability to control door locks straight from the video doorbell screen.

Adding these new features doesn't require a new panel or a truck roll. The update can be installed over the air or via the panel's USB port, and it makes a panel you already own more convenient and user-friendly every day. The GC Touch is available in both AT&T and Verizon versions, with the cellular communicator included from the factory.

What's New in Firmware 1.2

• Custom chime options. The primary user can now select which chime plays for door and window activity, instead of being stuck with one default sound.
• Voice annunciation with chimes. Voice announcements can now run alongside the chime options above, so the panel can speak and chime when a zone is faulted.
• Manual date and time. Date and time can be set right on the panel instead of relying only on automatic updates.
• Improved localization screens. The screens used to set language and region have been cleaned up.
• Scheduled Night Mode. Night Mode can now be set to turn on and off automatically at times you choose.
• Scheduled or automatic Dark Mode. Dark Mode can run on a schedule you set, or follow sunset and sunrise automatically.
• Lock control from the video doorbell screen. Locks can now be controlled directly from the video doorbell streaming screen, without backing out to a different menu.
• Faster code entry on PAD1. PAD1 no longer requires pressing "Enter" after a code, so arming and disarming take one less step.
• Chime added to walk test. Walk tests now include a chime, making it easier to confirm a sensor triggered during testing.

How to Update Your GC Touch

2GIG makes this update available over the air, through cellular or WIFI via Alarm.com. If you'd like your panel updated to Firmware 1.2 now, contact Alarm Grid support and we can get it scheduled. Updates using WIFI are free. If you don't have WIFI, there is a small charge for sending the update. The amount depends on the size of the download.

If you don't have WIFI at your panel and want to avoid this charge, you can update your panel yourself. Download the firmware from our site and apply it through the USB-C port on the back of the panel. Full instructions are available in our GC Touch firmware update guide, and you can download the firmware file from our downloads page. Alarm Grid passes the cellular update fee along at cost, with no markup, and it's added to your next billing cycle.

Update:

This issue was resolved September 17, 2026 before midnight. No further details were provided.

Alarm.com is dealing with an ongoing signaling issue that started on September 17, 2026, affecting signaling on some customer accounts, plus access to the Alarm.com dealer and customer interfaces. As of Alarm.com’s most recent update, the issue has not yet been marked resolved.

Alarm.com said the issue began around 5:00 PM ET on 9/17/26. By 5:50 PM ET, systems had stabilized, though customers could still see delays receiving notifications or sending commands like arming and disarming. As of the most recent update at 7:47 PM ET, Alarm.com reported the situation remains stable, but has not issued a notice that the issue is resolved.

What This Means for You

If you use Alarm.com’s app for notifications or remote arming and disarming, you may notice a lag or a missed alert while this is ongoing. It's also possible that a queued notification will be delayed, then come through at a later time.

What to Do Now

Since Alarm.com hasn’t posted an all-clear yet, keep an eye on your app for delayed notifications, a system that shows offline, or trouble sending commands. If you notice any of these, try closing and reopening the app first. If the problem continues or you have questions about your account, contact our support team and we’ll help you check your system’s status.
