Replacing a First Alert PROA7 or PROA7PLUS panel sounds simple enough. Alarm dealers perform replacements daily using AlarmNet360 (AN360), and when the recommended process is followed, everything works fine. But for a DIYer with no AN360 access, the proper order of things may not be clear.

DIY users often run into a unique problem. While in the process of replacing their existing PROA7 or PROA7PLUS, they also decide to add to the system and purchase new PROSIX sensors for that purpose. The hood's already up, might as well give it a tune up, right?

We've seen customers receive their replacement panel and immediately begin adding new sensors before performing the actual panel swap. We get it, new sensors are exciting! But please curb your enthusiasm until you've worked with one of our support agents to move all existing PROSIX sensors from the old panel to the new one. Otherwise, you may lose either your original PROSIX sensors or the new ones you've already added.

Why This Happens

Unlike older wireless sensors, PROSIX devices become permanently paired, or “married,” to a specific alarm panel during enrollment.

Once a PROSIX sensor is learned into a system, it cannot simply be moved to another panel later unless it is properly released from the original system first.

That means if you:

• Power up a replacement PROA7 or PROA7PLUS
• Enroll new PROSIX sensors into it
• Then later perform a panel replacement in AN360

...you may unintentionally overwrite sensor programming during the restore process.

This can go wrong in any number of ways, but the end result of not following the proper steps is that you lose sensor programming, and the affected sensors may not be recoverable. Once a PROSIX sensor has been paired with a system and powered on for 24 hours or more, it can no longer be factory defaulted. So a sensor in this position, paired with a system that no longer exists with no possibility of being factory defaulted, is a sensor that must be replaced.

But the Panel Does Exist!

Yes...and no. When a PRO Series panel is registered and communicating properly with AlarmNet360, the panel and server stay in constant sync. If programming changes, AN360 updates the panel "image" stored on the server. During a panel replacement, this saved image is transferred to the new PROA7 or PROA7PLUS.

If you get a new panel and begin programming it with new PROSIX sensors, you're creating a new and separate image. One that isn't synced with AN360. When the panel pairs with a PROSIX sensor, it chooses a channel for communication. You may be familiar with this process from older 2.4 GHz WIFI networks. The panel makes its choice based on the least noisy channel at the time of sensor programming. This information becomes part of the new image.

If that channel later becomes noisy, the panel can switch to a cleaner channel and notify all enrolled PROSIX sensors to follow it. If a sensor misses that message, it may remain stuck trying to communicate on the old channel. For more information on PROSIX wireless best practices, check out this FAQ.

The proper channel setting, the encryption key for each PROSIX sensor, and all other panel programming are stored in AN360 as part of the original panel's "image". When you initiate a panel replacement, you're telling AN360 to send the most recent image taken from the old panel to the new one. By necessity, this process replaces the new panel image you began creating when you started adding PROSIX sensors to the new panel prior to the swap. There is no way to merge these two images together.

If the replacement succeeds, the new panel becomes an exact copy of the last synced version of the old panel. That's the intended result. However, if you enrolled new PROSIX sensors into the replacement panel beforehand, those sensors will be overwritten during the replacement process. If they were powered on and paired for more than 24 hours prior to this, they cannot be factory defaulted and will have to be replaced.

The Most Important Rule

If you are replacing a PROA7 or PROA7PLUS system: DO NOT power up or enroll any new PROSIX sensors before the panel replacement is fully completed.

This includes:

• Door/window sensors
• Motion detectors
• Smoke detectors
• Heat detectors
• Glass breaks
• Key fobs
• Sirens
• Any additional PROSIX device

Leave any new sensors in the box until the replacement process is completely finished.

The Correct Way to Replace a PROA7 or PROA7PLUS

Follow these steps to avoid losing sensors or corrupting system programming:

1. Don't power on the new panel. Leave the new panel powered completely down until you are ready to physically replace the old one. Don't perform any programming on the new panel. If you have gotten to this point and you realize you've made the mistake of powering on the new panel and adding PROSIX Sensors, you should factory reset the new panel, then once all PROSIX sensors have received the reset command, power the panel down completely. You can tell a PROSIX sensor has been released if you open or fault the sensor and the LED begins blinking rapidly. If it's going to be hours or days before you can complete the replacement through AN360, remove the batteries from the new PROSIX sensors to conserve power.

If you happen to be replacing your existing panel with a used PROA7 or PROA7PLUS, be sure the "new" panel has the latest firmware. This ensures compatibility with all sensors. After updating, be sure to perform a factory reset before continuing. To do this, the panel will need to be powered on. As long as you complete these steps, then power back down before the swap is initiated in AN360, you're good. You'll need to work with your alarm dealer to arrange the firmware update, if one is needed.

2. Verify the programming. At this stage, you may want to verify that the "image" of the old panel in AN360 matches the actual programming in the old panel as closely as possible. You'll need to work with your alarm dealer to do this, as end users don't have access to AN360. If the old panel is completely dead, just do your best to complete this step.
3. Perform the panel replacement in AlarmNet360. Provide the MAC and MAC CRC from the new panel to your alarm dealer. They can now initiate the panel replacement process in AlarmNet360. If you plan to reuse the cellular module, PROWIFIZW*, or any other modules from the existing panel, power it down, remove those modules, and NEVER POWER THAT PANEL ON AGAIN WITHIN RANGE OF THE SENSORS unless your alarm dealer tells you to do so.

*When replacing a PRO Series panel paired with Z-Wave devices, AN360 can bring those devices to the new panel, preventing you from having to exclude and then include them again. However, this is only possible when the PROWIFIZW module from the old panel is moved to the new one.

4. Allow the replacement process to finish completely. After the replacement has been initiated in AN360, you should:
   • Power up the new PROA7 or PROA7PLUS.
   • Tap the Setup button for WIFI > choose your SSID > enter your password > Save > Connect.
   • Once connected to WIFI, tap Next, then tap Register.
   • Let the new panel fully sync with AlarmNet360. As it goes through the process of adding the existing PROSIX sensors, the panel will chime for each sensor.
   Do not interrupt this process. Depending on signal strength and the number of enrolled sensors, synchronization may take several minutes to complete. Be sure your alarm dealer also knows not to access the account in AN360 until the replacement process has fully finished.
5. Confirm all existing sensors restored properly. Tap the hamburger menu icon (☰) at the bottom center of the Home screen, then tap Sensors. You should see a list of all enrolled sensors. Verify that the sensor names are correct. To the right of each sensor name, the panel will display the signal strength and battery status of the sensor. Initially, these fields may appear blank. As the panel completes synchronization with the sensors, the signal and battery indicators will gradually populate. The replacement process is not complete until every sensor shows both a valid signal strength and an accurate battery level.

If the old panel was completely dead, or otherwise unable to communicate with the PROSIX sensors for an extended period of time, some sensors may show a low battery condition sooner than expected. PROSIX sensors continuously attempt to check in with the panel. If the panel does not respond, the sensors continue trying repeatedly, which can prematurely drain their batteries. If you suspect that an existing PROSIX sensor may have a dead battery, replace the batteries in the device and make sure it communicates fully with the panel before you enter panel programming.

6. Add new PROSIX sensors. Only after completing the previous steps should you begin enrolling any newly purchased sensors. Once you have verified that all programming has been synced from AN360 to the new panel, you can add additional sensors and make any other necessary changes.

Final Thoughts

We understand why DIY users try to prepare the new panel ahead of time. It feels like the faster and more organized approach. Unfortunately, with PROA7 and PROA7PLUS systems using PROSIX sensors, doing this can actually create major problems during the replacement process.

The safest approach is simple:

• Keep the replacement panel powered off.
• Leave all new PROSIX sensors unopened and unpowered.
• Work with your alarm dealer to complete the AlarmNet360 replacement first.
• Verify old sensors restored correctly.
• Finally, add any new devices and test for proper operation.

Following the proper order prevents lost programming, sensor lockouts, and hours of unnecessary troubleshooting. Alarm Grid customers who need to perform a PROA7, PROA7PLUS, or even VISTAH3 replacement with existing PROSIX sensors should contact support prior to taking any action on the replacement. Our support team is here Monday - Friday from 9:00 AM - 8:00 PM Eastern. You can contact us at 888-818-7728 or by emailing support@alarmgrid.com.

Resideo recently released a new firmware version for its PRO Series. Firmware 03.2476.204 is now available for PROA7 and PROA7PLUS panels, improving touchscreen response, clarifying the disarm process, and restoring PROSIX signal strength display. Learn more in the official Resideo notice.

Silent Alarm Button Renamed to Police Alarm (Silent)

This is the most important change in the update and it applies to all PRO Series models. In previous versions, during an active alarm, some users were pressing the Panic icon and then pressing the Silent Alarm button to silence the alarm. In reality, what they were doing was sending a silent panic signal, telling central station dispatchers to send the police immediately.

Doing this did silence the alarm, but without warning, police officers were being sent to the address. To make the function clearer, Resideo has renamed the button to POLICE ALARM (SILENT) and provided the instructions to enter a PIN in bold. The behavior is unchanged. But the new description makes it obvious that pressing this button calls the police, and that entering your user code is the correct way to silence an alarm.

Before (left) and after (right) — the Silent Alarm button is now labeled Police Alarm (Silent)

Touchscreen Sensitivity Fix

The touchscreen fix applies specifically to PROA7-FA and PROA7PLUS-FA panels. A small number of these units have experienced inaccuracy or lag when using the touchscreen, and the new firmware adjusts the sensitivity to resolve it. If your panel has felt sluggish or inconsistent to the touch, this update should take care of it. Standard PROA7 and PROA7PLUS models are not affected by this issue, though they can still receive the update.

RFSIX (PROSIX) Signal Strength Display Fix

PROSIX sensors paired with a PRO Series panel show their signal strength, making it easy to confirm they’re communicating properly and to troubleshoot any supervision issues. The display updates daily at 1:00 AM local time, or within about two minutes after using walk test mode.

The third fix addresses an issue that affected some PROA7-FA panels updated to firmware versions 03.2476.174 or 03.2476.183 in August 2025. On those systems, the RFSIX signal strength bar graph could disappear from the screen after the update. This new firmware brings that display back for affected panels. PROA7PLUS-FA and earlier ProSeries models aren’t impacted and don’t require any action. However, it is always recommended to keep your system updated to the latest firmware.

How to Get the Update

The firmware is now available through the AlarmNet360 portal. Alarm dealers can push it remotely to installed panels, or apply it during a new installation if the panel in the box is on an older version. Before the update can be pushed, the panel should:

• Be disarmed.
• Be connected to WIFI.
• Be free of alarm memory.
• Not have an AC loss condition.
• Not be actively reporting.
• Not be in walk test or programming mode.

New PROA7-FA and PROA7PLUS-FA units are already being shipped with 03.2476.204 pre-installed, though it may take a few weeks for all distributor inventory to cycle through. The firmware revision is printed on a label on the side of the box if you want to verify the version before opening a unit.

For help with your PRO Series system, the Alarm Grid support team is available Monday through Friday from 9:00 AM - 8:00 PM Eastern Time. Email us at support@alarmgrid.com, call us at 888-818-7728, or chat with us on our website. Live chat agents are available from 9:00 AM - 6:00 PM Eastern.

At Alarm Grid, we believe customers should have the freedom to purchase alarm equipment from the source that works best for them. That includes third-party distributors, online marketplaces, and even other end users.

We do not discourage customers from bringing their own equipment. However, it is important to understand that purchasing equipment outside of Alarm Grid can come with certain risks.

One of the most common issues involves used or outdated equipment. While a device may power on and appear functional, it could have hidden problems. Sensors may have reduced battery life, keypads could show excessive wear, and communicators might not perform as expected. In some cases, equipment may be damaged, outdated, or missing critical components.

We have also encountered activation issues with older LTEM-P, LTEM-PX, and IP-COM communicators purchased through third-party sellers. Some older stock did not receive a required critical firmware update and can no longer be serviced. Units with MAC addresses beginning with B82CA0, typically manufactured around 2020 or 2021, and some beginning with 48A2E6, may be affected. Even if these communicators are new in box, they may not be capable of activation.

Another serious concern is account association. Many alarm communicators are registered to an AlarmNet or Alarm.com account. If a used communicator was previously installed and removed during an upgrade, it may automatically attempt to re-register to the original account.

When that happens, the communicator ties back to the previous dealer or seller. If they do not release it, we cannot activate or service the unit. In some cases, the only options are to convince the seller to release the device or purchase a new communicator, which can delay monitoring by days.

Before purchasing from a third party, confirm the seller has a clear return policy. Verify that the communicator firmware is current and that it does not have a B82CA0 or 48A2E6 MAC prefix. Whenever possible, purchase newer equipment from a reputable distributor or retailer.

If you already have a communicator, and you suspect it may be affected by this issue, do not connect it to a wired network before activation. Immediately after powering it up, press and hold the test or registration button for 30 seconds, then release it to default the unit. Completing this step prior to your activation appointment can help prevent registration conflicts.

Ultimately, the simplest way to avoid these issues is to purchase new equipment from a trusted source. When a communicator is purchased through Alarm Grid and found to be defective, we can typically process a replacement in less than 24 hours, helping to minimize downtime.

Alarm Grid is here to support our current and future monitored customers, no matter where you purchase your equipment. We simply want you to begin the process informed and prepared. Our team is available Monday through Friday from 9:00 AM to 8:00 PM. If you have questions, reach out to us by email at support@alarmgrid.com or by phone at 888-818-7728. You can also use the live chat feature available on our website at alarmgrid.com.

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.

Update 12:30 PM EDT: Total Connect 2.0 Email Notification Issue Resolved

This morning, Resideo identified and resolved an issue that was affecting Total Connect 2.0 email notifications. The temporary problem was caused by a third-party vendor, Mailjet, and may have prevented the delivery of system notifications, password reset emails, and welcome messages.

Apparently, the undelivered email messages were queued, and when service was restored these messages went through. This may cause some Total Connect 2.0 notifications to arrive out of sequence until all queued messages are delivered. Any time you receive a notification that you question, log into Total Connect 2.0 and check the Activity screen as well as the current status page. You can also check the panel's Event Log from the touchscreen by tapping Menu (≡) > Events.

Who Was Affected?

The service disruption was reported at approximately 8:44 AM EDT. If you were expecting an email from Total Connect 2.0 this morning and did not receive it, you were likely affected by this brief outage.

Why Redundancy Matters

This incident highlights the importance of enabling multiple notification methods. We strongly recommend setting up push notifications on your mobile device as a reliable backup. For customers affected by today's email issue, push notifications would have still been delivered successfully, ensuring no critical alerts were missed.

As of approximately 12:30 PM EDT the issue has been resolved. If you're an Alarm Grid monitored customer and you continue to have any issues receiving email notifications for TC2 alerts, you can contact our support team by calling 1-888-818-7728, M - F 9:00 AM - 8:00 PM. You can also email us at support@alarmgrid.com.

The problem outlined in this notice arises if you attempt to pair an older firmware ProSeries touchscreen keypad to a newer or recently updated ProSeries panel. If the keypad is on version 3.324.46 or lower, and the panel is on 03.3206.57+, then the keypad won't pair and ceases functioning.

ProSeries keypads, specifically the PROWLTOUCH and PROWLTOUCHC, may require a special upgrade process to install the latest firmware in certain cases. Normally, these keypads receive updates from the ProSeries panel. However, if the keypad can’t pair with the panel, or loses connection, it won’t be able to receive the update.

If you have a ProSeries panel and touchscreen keypad that stay paired, connected to WIFI, and in regular communication most of the time, you shouldn’t have any issues. When the panel updates its firmware via WIFI, it will pass along any available update to the keypad automatically. If your keypad has trouble staying connected, you may want to set it up using Access Point (AP) Mode. This helpful FAQ can show you how.

As we mentioned earlier, most users won’t run into this issue. However, certain situations make it more likely. For example, if you buy a used ProSeries touchscreen keypad, or if you purchase one from stock that has been sitting on the shelf for a long time, you may encounter the problem.

If your panel hasn’t been updated regularly, jumping from an older firmware straight to the latest release can cause the issue described above. It can also occur with panels that have been installed for a long time and communicate with AlarmNet360 only over cellular.

If your system has a PROWIFI or PROWIFIZW module, the panel and keypad may have been paired using AP Mode. Since the panel can’t update firmware over cellular, suddenly connecting it to WIFI could trigger an upgrade to the latest version, potentially leaving the keypad behind on older firmware.

If you purchase a new keypad that has been sitting in stock, and you discover it suffers from this issue, you should be able to return it to the dealer or distributor for a refund or replacement. However, if you buy a used keypad, inherit one with a home purchase, or receive a second-hand keypad as a gift, you may need to follow specific steps to update it. The first step is to check the firmware version.

Our Advice: If you’re considering buying a used touchscreen keypad, ask the seller to verify its firmware before you commit. Request a picture of the firmware screen as proof. Even if the keypad isn’t paired to a panel, you can still see its firmware version.

To check the firmware, power on the keypad and let it attempt to connect to a panel. Press "Pair to Panel". On the next screen, you’ll see options for connecting the keypad to WIFI. At the bottom of that screen, the current firmware version is displayed.

Once you know the keypad firmware, verify your ProSeries panel version. On the panel begin by tapping the Menu icon (≡) at the bottom center of the panel screen. Scroll down and tap Tools > Enter the Installer or Master Code (4112 or 1234, by default) > tap System Information > General. The panel firmware version will be displayed in a XX.XXXX.XX format.

If the keypad is on version 3.324.46 or lower and the ProSeries panel is on firmware version 03.2306.57 or higher, the touchscreen keypad will not pair with the panel. There is no way to make the keypad in this example pair with a panel at that firmware version. However, the keypad will still function if it is used with a panel on a lower firmware version that is then upgraded properly.

Important Note: You cannot downgrade the firmware on a ProSeries panel, per Resideo support.

Another drawback to this situation is that an end-user can't control when their panel updates, or to what version. The only control you have as an end-user is that if you remove your ProSeries panel from WIFI, it will not receive firmware updates. These panels don't update using cellular data.

Important Notes At A Glance:

• Keypads on v3.324.46 or lower can’t pair with panels on v03.2306.57 or higher.
• ProSeries panel firmware can’t be downgraded.
• Panels update only over WIFI, not cellular.
• Disconnecting WIFI stops panel updates.
• Check firmware before buying a used keypad.
• Contact your alarm dealer for upgrade help.

If you're a customer with concerns about this potential issue, contact your alarm dealer. They will be able to push the necessary upgrades to your ProSeries panel in the correct order. Alarm Grid has a list of customers with touchscreen keypads that may be susceptible and we are proactively reaching out via email or phone to those customers. If you are not an Alarm Grid customer your alarm dealer should have a similar list.

As we told you in February, Resideo is sunsetting first-gen Total Connect 2.0 cameras. After July 31, 2025, they’ll no longer work in TC2 and will be removed from all accounts. Any recorded clips will also be deleted. Be sure to download and save any important footage outside of TC2 now.

The sunsetting of first-gen Total Connect 2.0 cameras is now just days away. If you still have any of the original TC2 cameras on your account, you should be preparing to replace those cameras with new ones. Otherwise, you will lose video coverage in those areas.

Even more important is downloading any critical video clips uploaded from first-generation cameras. Once the sunset occurs, both the cameras and their recorded footage will be removed from Total Connect 2.0 and will likely be unrecoverable.

It's easy to save these video clips from Total Connect 2.0.

1. Log into TC2 as normal.
2. Tap Activity from the menu options at the bottom of the screen, or from the left navigation pane, if you're logged in on the website.
   
   
3. From the Activity screen, find the clip you want to save.
4. Tap the three dots to the right of the clip title and then choose Download.
5. In iOS you can access your downloaded clip from Photos. In Android devices, the options may vary depending on device manufacturer, but generally you can access the clip from Files (All or Downloads) and from Gallery:

Recommended VX Series Replacements for EOL Cameras

Product Name	Recommended Replacement
IPCAM-WI	VX5 Indoor Camera
IPCAM-WI2	VX5 Indoor Camera
IPCAM-WL	VX5 Indoor Camera
IPCAM-WO	VX3 Outdoor Camera
IPCAM-PT/IPCAM-PT2/PT2A	One or More VX5 Indoor Cameras
ACU	Replace ACU and Camera with appropriate Indoor or Outdoor VX5 Camera
AP/WAP-PLUS/WREX	No Replacement Available

The first Total Connect 2.0 cameras did their job well after launching in late 2011 or early 2012, but video tech has come a long way since then. Today's AI motion detection is way better than the old method of analyzing pixel-changes. The newer cameras, such as those in the table above, use AI to actually tell the difference between a person and an animal, for example. With all the available improvements, it makes sense to phase out the original cameras.

Are you clinging to an older alarm system that uses a phone line? You're not alone. Many reliable old systems are still in use, but finding POTS service may be a challenge. Dialer capture modules offer an easy way to update your older system, allowing it to communicate over cellular networks.

An LTEM-P is shown on the right, and the PRODCM is shown on the left below. The PRODCM mounts inside the enclosure for the LTEM-P:

This means you can keep your existing alarm panel and sensors while upgrading to a more reliable and future-proof communication method. Here we'll explore two popular options: the Resideo PRODCM and the all-new Alarm.com Universal Communicator (LX30B-Q50TU-AUC).

Resideo PRODCM Dialer Capture Module

The Resideo PRODCM is a compact plug-in module designed to work with Resideo's LTEM-PA and LTEM-PV communicators. It's a great choice for alarm panels that don't support Resideo's ECP data communication but can send signals in the Contact ID (CID) format through a telephone output.

Key Features of the Resideo PRODCM:

• Seamless Integration: The PRODCM cleverly mimics a phone line. When your alarm panel tries to dial the central station, the module provides a dial tone, receives the dialed number, and then captures the Contact ID message. If a panel can report using CID format and has a working dialer, it can be used with the PRODCM
• Reliable Communication: Once the alarm signal is captured, it's passed to the LTEM-P series communicator, which then sends it to the central monitoring station over the internet, if available, or a cellular network, if enabled.
• One-Way Communication: It's important to note that the PRODCM only supports one-way communication from the control panel to the central station. This means features like remote access via Total Connect 2.0 or remote downloading to the panel are not supported.
• Simple Installation: The module plugs directly into the main board of an LTEM-P series communicator. The alarm panel's Tip and Ring terminals are then wired to the terminals on the PRODCM.

Alarm.com Universal Communicator LX30B-Q50TU-AUC

The Alarm.com Universal Communicator (AUC) LX30B-Q50TU-AUC is another excellent option for upgrading older POTS-based security systems. It is compatible with a wide range of panels from manufacturers like DSC, Honeywell, GE, and Paradox. This device not only provides a modern communication path but also adds some smart features.

The Alarm.com LX30B-Q50TU-AUC is shown below:

Key Features of the Alarm.com LX30B-Q50TU-AUC:

• Broad Compatibility: The AUC can work with many different brands of older alarm panels, making it a versatile choice. It supports both Contact ID (CID) and SIA signaling formats.
• Interactive Services: A major advantage of the AUC is its ability to connect to the Alarm.com platform. This allows you to remotely arm and disarm a compatible system using the Alarm.com app and receive notifications for events, like alarms.
• Remote Arming and Status: By using a keyswitch zone and a programmable output (PGM) on your existing panel, the AUC can provide remote arming capabilities and allow you to view the system's status from your phone. To clear an alarm, the user must log into the customer website. You cannot clear an alarm through the app. For VISTA panels, the alarm must be cleared locally through the panel keypad. The system can't be armed again until the alarm is cleared locally.
• Flexible Installation: The AUC wires to the control panel's auxiliary power and telephone terminals. For remote arming and status updates, it also connects to a zone and a PGM on the panel.

Feature Comparison

Which One is Right for You?

Choosing between the Resideo PRODCM and the Alarm.com LX30B-Q50TU-AUC really comes down to what you want to achieve.

If your main goal is to simply replace your old phone line with a modern, reliable cellular or internet communication path to a central station, and you already have or plan to purchase a Resideo LTEM-P series communicator, the PRODCM is a straightforward and effective solution.

However, if you're looking to not only upgrade your communication path but also add smart control to your existing system, the Alarm.com AUC LX30B is the clear winner. The ability to remotely arm and disarm your system and receive notifications through the powerful Alarm.com platform brings a whole new level of convenience and peace of mind to an older alarm panel.

Update 6:46 PM 05/12/25: Per AlarmNet and Resideo, both Total Connect 2.0 and alarm communications are fully restored. This update isn't time stamped, so it's unclear exactly when services were restored. Alarm dealers may continue to see some issues in programming legacy devices and video-only accounts. PRO Series and VISTAH3 device programming is completely restored.

Original Post:

AlarmNet has alerted all dealers to an issue with their communicators that began at 8:15 AM today. They are investigating the issue and working diligently toward a solution. Preliminary investigation shows that this interruption is not the result of malicious activity or a security breach.

What You May See:

As a result of this issue, you may have seen a communicator failure message on your system. This could show up as a "Check 103" message, "Reporter Failure", and possibly others. You may also have noticed issues logging into Total Connect 2.0, or delays or failures in completing commands using TC2.

According to AlarmNet, they are seeing some system recovery with improvements in latency, etc. However, the AlarmNet network is still not at 100%, so if you notice an issue logging into Total Connect 2.0, or an issue with sluggish or failed command execution, this is why.

In the past, we've seen queued signals and notifications being delivered once communication is restored. This can present as a notification coming through that seems out of place. For example, you may receive a notification that your system was disarmed when you know that you armed it. This is just a disarm notification from a previous instance that was delayed in being delivered. The best thing to do is log into Total Connect 2.0 and verify your system status. You can check the panel's event log to confirm exactly what has taken place on your system.

What You Can Do:

If you receive a trouble message on your system you silence it by acknowledging it. This process can vary depending on what system you're using. On a VISTA system, press any key on the keypad to silence the trouble beeping. Enter a disarm sequence by pressing your four-digit code plus one (1) or OFF. Do this twice.

If the communication issue has been resolved, the second disarm command will clear the trouble message from your keypad. If not, the message will remain until the condition has been resolved and you enter a disarm command again.

On the various touchscreen panels or keypads, you should be able to follow prompts on the display to silence and clear the trouble message. On the PRO Series panels, tap the red alert indicator at the bottom right of the display. This will silence the trouble beep and bring up the alert screen. Any active trouble conditions will be displayed. Press "Clear" at the upper right and enter a valid user code.

As with a VISTA system, if the trouble condition has been resolved, this will clear the display. If not, the message will remain under "Active Issues" until the trouble condition is resolved. In this case, until whatever is causing the communication problems has been taken care of. Once the condition has been resolved, press "Clear" again and enter your user code to clear the message.

Stay tuned, as we receive updates we'll update this blog post with any available information.

The First Alert VISTAH3 is Resideo's premiere hybrid panel. It offers built-in wired zones and a built-in PROSIX receiver. With an added module, it can support legacy RF from various manufacturers. However, a touchscreen keypad must be added for local programming, and WIFI isn't included.

The VISTAH3 supports up to 96 zones total, with up to four (4) partitions. There are eight (8) built in hardwired zones, expandable up to a total of 64 hardwired zones. The panel has an RJ45 connector built-in for hardwired Ethernet. If a hardwired network connection isn't possible, the panel can support WIFI with the addition of a module.

The VISTAH3 supports the following agency listings (in no particular order):

• UL 985 - Household Fire
• UL 1023 - Household Burg
• UL 2610 - Commercial Burg
• UL 1637 - Home Healthcare Signaling Equipment
• UL 2017 - Safety General Purpose Signaling Devices
• ULC S545 - Residential Fire Warning System Control Units (Canada)
• ULC S304 - Standard for Control Units, Accessories and Receiving Equipment for Intrusion Alarm Systems (Canada)
• ANSI/SIA CP-01 - False Alarm Reduction Standard

Once the VISTAH3 is registered with AlarmNet it can be used with Total Connect 2.0. This allows the end-user to monitor their system remotely, check system status, arm and disarm from nearly any location, control home automation devices that are associated with the account and view video, if included in the monitoring plan.

Like the Honeywell Home PROA7 and PROA7PLUS and the Resideo PROA7C and PROA7PLUSC the First Alert VISTAH3 can be programmed remotely through AlarmNet360 or locally through a touchscreen keypad. Unlike the PRO Series panels though, the VISTAH3 doesn't come with a touchscreen interface from the factory.

To add a touchscreen to the VISTAH3, you must also add WIFI capability. This can be done by adding either the PROWIFI (WIFI only) or the PROWIFIZW (WIFI and Z-Wave Plus). Once the panel has access to WIFI the Honeywell Home PROWLTOUCH, Resideo PROWLTOUCHC, or the First Alert VISTAHTCHWLC can be added.

Up to eight (8) touchscreen keypads are supported per VISTAH3 panel. You can read all about the number and types of supported keypads in this helpful FAQ. In the table below, we have a list of all the VISTAH3 associated products with links to each.
