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 (¡Ô) > 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 (¡Ô) 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:

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.

In addition to the individual components listed in the table, we provide a list of curated kits below.

Time for the CellBounce to, well, bounce. This device, which served as a temporary bridge for AT&T customers clinging to their 3G communicators, is now being discontinued. For those who rely on CellBounce to convert 3G signals for use on the LTE network, it's time to consider the next steps.

Mark your calendars: as of May 1, 2025, AT&T will officially cease support for CellBounce devices on its network. This means if you're currently relying on a CellBounce to bridge the gap between your old AT&T 3G/4G communicator and the AT&T LTE network, it's time to upgrade.

Failure to upgrade to a new LTE communicator, or a new system before the deadline will likely result in a complete loss of communication, compromising alarm signals. This includes critical life-safety signals like fire and carbon monoxide alerts.

You may be wondering which communicator to choose. Below, we'll give you some suggestions for how best to move past the Resideo CellBounce and that old 3G/4G communicator:

We realize upgrading to a new panel may be a big undertaking for a DIYer. We've got content on upgrading from a VISTA-20P to a VISTAH3 and on upgrading from several older panels to the PROA7PLUS:

• Upgrade from an L3000 to a PROA7PLUS
• Upgrade from an L5200 to a PROA7PLUS
• Upgrade from an L5210 to a PROA7PLUS
• Upgrade from an L7000 to a PROA7PLUS

If you fail to replace the Resideo CellBounce before the deadline, here's what you may experience:

• Communication Failures: "Comm fail," or communication failure, means your alarm system's regular check-in with AlarmNet didn't happen and they sent a message to the monitoring station. These supervision check-ins usually occur daily or monthly. If a comm fail happens, the monitoring station will normally contact the alarm dealer, who will then contact you, though exact procedures may vary. For Alarm Grid customers with cellular communicators, these check-ins are typically set for every day. It is possible that your system is set as "unsupervised". If that is the case, your system might be incapable of communicating and neither you nor the monitoring station would know.
• Trouble message on display. This issue can vary widely, depending on your panel type and supervision settings. When a cellular communicator is in use, there is a "cell fault time" setting within communicator programming. By default, this is usually set to 60 minutes. With this setting, if the communicator loses contact with the cellular network for 60 consecutive minutes, a trouble message is displayed by the panel. This means you'll likely see that there is a problem before your alarm dealer. This may be displayed as a bF or Check 103 depending on the panel and keypad used. If a CellBounce is the issue, the most effective way to clear this message permanently is to disable the cellular communicator in panel programming. This will effectively disable cellular reporting. A better option is to upgrade the communicator or the system.

If you happen to have an IP and GSM communicator, it is usually possible, depending on your communicator version, to disable only the cellular path for the communicator. This will leave the IP communicator working. This might be a temporary solution, until you can upgrade to a new LTE communicator, or a new system.

The CellBounce was always intended as a short-term fix for a long-term problem. Let's face it, some people just don't like being told they have to upgrade their stuff. I remember when the old 2G network shut down, I had family members who clung to their old phones right up until the bitter end! But eventually, we all have to move with the times. Funny thing is, those same family members wouldn't give up their smartphones without a fight today.

Although users accustomed to the Lyric's all-in-one style and convenience are unlikely to switch to a hybrid panel, it is still possible. Therefore, in this installment of "Preparing for the Eventual Lyric End-of-Life," we will discuss replacing the Lyric with the new First Alert VISTAH3.

Replacing The Lyric With A Hybrid Panel:

The First Alert VISTAH3 may be a good choice to replace an aging Lyric. Much like the PRO Series panels, the VISTAH3 supports SiX and PROSIX sensors right out of the box. It can also support a variety of wired and wireless devices.

The VISTAH3 is more of a traditional system, like the VISTA-20P. The main control panel is installed in a remote location, away from entry points. Then, either wired or wireless keypads are used to control the system. This is the first panel Resideo has produced that can support wired zones, wireless devices, legacy wireless, ECP zone expansion, and V-PLEX zone expansion. That's every type of expansion the company has ever made.

While the VISTAH3 might seem complex, its programming closely resembles that of the PRO Series panels. When replacing a Lyric system, you may not immediately utilize the new panel's more advanced features. However, it's nice knowing these capabilities are available for future expansion.

Recommended Keypads:

DIY installers of the VISTAH3 should be aware that local programming requires a touchscreen WIFI keypad. This means adding either a PROWIFI (WIFI-only) or a PROWIFIZW (WIFI and Z-Wave Plus) module before connecting a programming keypad.

There are three (3) touchscreen keypads to choose from when using the VISTAH3. The Honeywell Home PROWLTOUCH, the Resideo PROWLTOUCHC, and the First Alert VISTAHTCHWLC. If you'll be purchasing a new touchscreen keypad for use with this panel, we recommend the First Alert model. It is compatible with all versions of the VISTAH3 panel without having to undergo a firmware update.

Before using either the PROWLTOUCH or PROWLTOUCHC with the VISTAH3, a firmware update is required. This update can take up to 30 minutes to download and install. The VISTAH3 panel must be registered and updated first; then, it will automatically push the necessary firmware to the keypad. If you intend to set up and program your system before registration, the First Alert VISTAHTCHWLC is the best keypad for you.

Although touchscreen keypads offer the best functionality and control of both the system and automation devices, it is recommended that you have at least one wired keypad to provide control of the alarm system in the event of a wireless failure.

The First Alert VISTAHLKP and First Alert VISTAHPKP both connect to the panel through the iBus. This new bus technology leverages RS-485 and provides robust flexibility for long wire runs.

RS-485 is not a protocol. Instead, it's a standard that defines the electrical characteristics of drivers and receivers in a serial network. It's been commonly used in manufacturing automation for years due to its relative immunity to electrical noise. It supports long wire runs in noisy environments and multiple devices connected to a single bus.

Support for Legacy Wireless:

The VISTAH3 is compatible with the First Alert VISTAHTKVRWL for legacy wireless zone support. This legacy wireless takeover module works exactly like the PROTAKEOVER module used with the PROA7C and PROA7PLUSC. The biggest difference between the two modules is in their antennas.

The PROTAKEOVER includes a new PRO Series panel backplate with integrated antennas. The original backplate must be replaced for proper module function. Similarly, the VISTAHTKVRWL utilizes two external antennas, installed within the VISTAH3 panel's enclosure, to ensure effective wireless signal reception.

Similar to the PROTAKEOVER, the VISTAHTKVRWL cannot support multiple legacy wireless frequencies simultaneously. That means it cannot support both 5800 Series 345 MHz sensors and 2GIG 345 MHz sensors. If your Lyric panel incorporates both sensor types, a decision will have to be made as to which wireless series to keep and which to replace.

Communicators:

The VISTAH3 features an integrated Ethernet communicator. If a wired Ethernet connection is unavailable, or if you plan to use a WIFI keypad, you'll need to add either the PROWIFI (WIFI-only) or PROWIFIZW (WIFI and Z-Wave Plus) module. For enhanced reliability, consider installing either the PROLTE-A or PROLTE-V2 LTE cellular communicator. However, similar to the PRO Series, the VISTAH3 requires an Ethernet or WIFI connection for firmware updates. Over-the-air updates are not allowed via cellular connection.

Total Connect 2.0:

As with choosing a PRO Series panel as a replacement for the Lyric the First Alert VISTAH3 also comes with the added convenience of supporting Total Connect 2.0 (TC2). Whether you've already been using TC2 with the Lyric, or you want to begin using it with the replacement panel, the VISTAH3 provides you with that opportunity.

TC2 is the remote accessibility platform offered by AlarmNet. AlarmNet is a subsidiary of Resideo. It started life as a means of providing backup communication for alarm systems that relied on telephone lines for a communication path. A savvy burglar could cut the phone lines from outside the building, then make entry, secure in the knowledge that the alarm system was unable to communicate.

AlarmNet changed all that by providing cellular communication capabilities for alarm systems. Those old analog cellular communicators were used only in instances where the primary means of communication, namely the copper phone line, was compromised.

Now, cellular communication is often the primary or the only communication path used. With the addition of IP communication, in the form of an Ethernet or WIFI path alarm users can have the best of both worlds. The speed of IP communication with the reliability of cellular. Total Connect 2.0 leverages these paths to provide remote control, along with real-time remote monitoring and notification capability.

Be sure to check out the rest of this series on Preparing For the Eventual Lyric End-of-Life. In Part 1, we discuss the considerations when continuing to use the Lyric. In Part 2 we discuss replacing the Lyric with another all-in-one panel, in particular with one of the PRO Series systems. In Part 4 we discuss using an Alarm.com compatible system as a replacement.

Preparing for the Eventual Lyric End-of-Life - Part 2

Preparing for the Eventual Lyric End-of-Life - Part 4

I began with the intention of making a single post about possible replacement options for the Lyric. But the post grew out of control and took on a life of its own! So instead, I'm making a series of posts, one for each suggestion. In Part 2, we'll concentrate on the Resideo PRO Series panels.

The Lyric was discontinued in 2021 and production of all SiX Series sensors has now ended. With that in mind, I've been looking at the various ways forward for current Lyric users. In Part 1 we explored the option of simply continuing to use the Lyric Alarm. In Part 2, we'll discuss replacing the Lyric with a like-panel. In this case, the Resideo PROA7C or PROA7PLUSC.

Replace the Lyric With Another All-In-One System:

If you choose to replace the Lyric panel, using another all-in-one system is a great idea. The Honeywell Home PROA7, Resideo PROA7C and PROA7PLUSC panels are a natural choice. The PROA7, PROA7C and PROA7PLUSC can support nearly all the same sensors as the Lyric, though there are some exceptions as we discuss in this FAQ.

NOTE: The Honeywell Home PROA7 and the Resideo PROA7C are virtually the same panel with a different manufacturer's badge on the front. The Honeywell Home PROA7PLUS and the Resideo PROA7PLUSC are also virtually the same. In early 2025, Resideo announced they would discontinue the PROA7PLUS and begin only manufacturing the PROA7PLUSC.

Between the two panels, the PROA7PLUSC is the most like the Lyric in terms of features. For example, the Lyric has a front-facing camera as does the PROA7PLUSC. The PROA7C has no camera. The PROA7PLUSC comes with both WIFI and Z-Wave support included, the PROA7C doesn't, though you can add those features. You can see a full feature comparison between the PROA7C and the PROA7PLUSC here.

The PROA7C and PROA7PLUSC both support PROSIX and SiX Series sensors right out of the box. When a SiX Series sensor is added to either of the PRO Series panels the sensor is updated, effectively becoming a PROSIX sensor. Once this upgrade occurs, the SiX Series device cannot be downgraded again. That means it can never work with a Lyric panel after the upgrade takes place.

Another important thing to remember is that every SiX and PROSIX sensor can only be paired to one panel at a time. When replacing a Lyric system with a PRO Series panel, a specific set of steps should be completed, and in the proper order. You can read the steps for replacing a Lyric with a PRO Series panel here.

You'll need to work closely with your alarm dealer to complete a replacement steps linked above as only your alarm dealer can perform certain steps in the list. There is no direct replacement option through AlarmNet360 currently, as there is when going from one Lyric panel to another Lyric panel. You will be reprogramming all your zones when performing this replacement.

As previously mentioned, SiX Series devices are paired with the Lyric panel during programming. To disassociate a sensor for use with another panel, either the individual zone must be deleted while the sensor is powered on and can receive the delete command, or the entire panel must be defaulted with all SiX sensors powered and receptive to the default signal.

In the event of a Lyric panel failure with multiple paired SiX Series devices, sending the delete or default command may become impossible. Consequently, not only would the Lyric panel require replacement, but all paired SiX Sensors would also need to be replaced, as they would be unresponsive to pairing with a new panel. For this reason, it is better to replace the Lyric panel before a failure occurs.

Honeywell 5800 Series Support:

The PROA7C and PROA7PLUSC don't offer native 5800 Series support. To support 5800 Series devices a Honeywell Home PROTAKEOVER module must be added. With a PROTAKEOVER the system can support any one (1) legacy RF frequency from the following:

• Honeywell 5800 Series - 345 MHz
• 2GIG Unencrypted Sensors - 345 MHz
• Qolsys/Interlogix Unencrypted - 319.5 MHz
• DSC Legacy (not PowerG) - 433 MHz
• Bosch - 433 MHz

In spite of the fact that several of the above mentioned manufacturers use the same basic frequency for legacy wireless, none of these are interchangeable. That means you can only support 2GIG or Honeywell 5800 Series, not both. We have tested this and this is a definite limitation. Incidentally, the FF345 behaves as a Honeywell 5800 Series device rather than a 2GIG one. The same rule holds true for DSC and Bosch 433 MHz sensors.

Communicators:

A key advantage of Resideo and First Alert panels is their versatile communication options, offering IP, LTE cellular (AT&T or Verizon), or dual-path connectivity. However, it's important to point out that IP-only communication leaves the system vulnerable to network outages. LTE cellular communication is much more reliable, though it is slightly more expensive when choosing a monthly monitoring plan.

Despite the reliability of LTE cellular communication, Alarm Grid still recommends a connection to WIFI. This is due in part to the fact that PRO Series panels can only receive over-the-air firmware updates via WIFI. Updates will not be sent using cellular data. If you have a panel in a location with no WIFI available, you can use your cell phone as a wireless hotspot. The panel will see this as a WIFI connection and should be able to download any available update.

Apple HomeKit Support:

If your Lyric is using Apple HomeKit you will be able to continue using it with the Resideo PROA7PLUSC. Unfortunately, the Resideo PROA7C does not support HomeKit. Also, once you have the PROA7PLUSC configured, you'll need to go through the process of setting up HomeKit with the new PROA7PLUSC from scratch. There is a bit of difference in using the PROA7PLUSC with HomeKit, you can read about that here.

HomeKit is a great way to automate you lifestyle-enhancement devices and integrate them with your alarm system, or vise versa. However, there are limitations to the security and life-safety devices you can monitor with it. For example, Apple HomeKit doesn't provide detailed notifications for fire or carbon monoxide alarms. You can read a comparison between HomeKit and Total Connect 2.0 here. Because of these differences, we still recommend that HomeKit users also use TC2.

Total Connect 2.0:

Switching from the Lyric to a PRO Series panel enables continued or new access to Total Connect 2.0. This remote platform mirrors panel functionality, allowing you to monitor status, arm/disarm, control automation, and program scene-based automation schedules and system event triggers.

If you must replace a PROA7 or PROA7PLUS* panel, it is important to perform not only the proper steps but in the proper order. Failure to do so may cause some PROSIX sensors to become unresponsive, forcing a replacement of those sensors. In this blog, we'll outline the proper procedure.

As we've often noted, Resideo's SiX Series and PROSIX sensors are uniquely paired to the alarm panel during initial panel and sensor configuration. Once paired, they cannot be used with any other panel until they are properly unpaired from the original. Without this unpairing, a failed original panel can potentially render a sensor unusable.

AlarmNet360 (AN360) acts as an important safeguard. When a PRO Series panel is registered with AN360, it begins near-constant two-way communication. Any programming change at the panel triggers an upload of the panel's configuration to AN360. This creates a backup of the panel's current programming, including the essential configuration information for all PROSIX sensors.

In the event of a PRO Series panel failure, a replacement panel can be configured with the exact same zone and system programming parameters as the original. The sensor information, including wireless channel data and encryption keys, is transferred to the new panel, ensuring it matches the existing sensor programming. By following the proper replacement process, the existing PROSIX sensors function seamlessly, unaware of the panel change.

However, a significant problem arises when DIY users add new PROSIX sensors to the replacement panel before a proper AN360-based panel replacement is performed. We've observed this issue on several occasions. Customers, awaiting a scheduled panel replacement, decide to add new PROSIX sensors in the interim.

Because the panel replacement requires dealer involvement, and in the case of Alarm Grid customers, a scheduled appointment with an Alarm Grid activator, customers often utilize their wait time by tinkering with their system. This can include adding new PROSIX devices.

When the scheduled replacement occurs, customers often overlook the newly added sensors, failing to mention them to the activator. This oversight, due to the unique way PROSIX sensors function, can create a serious conflict.

PROSIX sensors communicate using 2.4 GHz, similar to some WIFI networks. Like WIFI, PROSIX sensors utilize channels within the 2.4 GHz band. If a PRO Series panel detects interference on its current channel, it can instruct all PROSIX sensors to switch to a less congested one. This ensures the most consistent ongoing communication.

During pairing, encryption keys and the designated communication channel are established. All PROSIX devices on a PROA7 or PROA7PLUS panel operate on the same channel. This channel information is regularly backed up to AN360 and transferred to the replacement panel during the swap.

Consequently, AN360 holds a complete backup of the original panel's configuration. However, the new panel now contains configuration information for the recently added sensors, including new encryption keys and a potentially different 2.4 GHz channel.

During the replacement process, the new panel's configuration is overwritten with the backup from the original panel. The information for the newly added PROSIX sensors is lost. Effectively, the new panel becomes the original panel. Unfortunately, the new sensors were paired with the actual new panel, not the restored version.

Consequently, from this point there is no mechanism to instruct the newly added sensors to release or unpair, allowing them to be paired with the restored panel. There is a narrow 24 hour window from the time of enrollment where most PROSIX sensors can be defaulted. If the window for default is missed, and the replacement through AlarmNet360 is completed, the newly added PROSIX sensors become unusable. For that reason, we recommend anyone replacing a PRO Series panel follow these steps.

Recommended Steps, In Order, For Replacing a PROA7 or PROA7PLUS:

1. Make sure the replacement panel is the same revision, or higher, as the original panel. Work with your alarm dealer to verify the panel versions. It is possible to replace a PROA7 with a PROA7PLUS. It is NOT possible to replace a PROA7PLUS with a PROA7.
   NOTE: Firmware updates require WIFI. If your location doesn't have WIFI you can use a phone as a hotspot. This will be seen as a WIFI connection by the panel and AN360, and should allow you to perform the update. Obviously, this means the panel will need a PROWIFI or PROWIFIZW.
2. Make sure both panels are powered down.
3. Your alarm dealer will begin the replacement process in AN360. They will instruct you when to move to the next step.
4. With both panels still powered down, remove any modules such as PROLTE-A/PROLTE-V2, PROTAKEOVER, PROWIFI/PROWIFIZW from the original panel and install them into the new panel. If you have a PROTAKEOVER, be sure you move the backplate from the old panel to the new panel as well. It contains the antennas for the PROTAKEOVER.
5. Power up the NEW panel. You can immediately join the WIFI network when prompted, if applicable, or wait for the cellular module to initialize then press NEXT.
6. Press REGISTER, when prompted. The panel will register then pull all available programming from AN360. When this process is finished, the panel will display the Home screen.
7. If any PROWLTOUCH or PROWLTOUCHC WIFI keypads are associated with the panel, each will prompt you to "Pair to Panel". Do this at each keypad.
8. If the original panel was a Version 01 or 02 and there were PROINDMV Motion Viewers associated with it, these will have to be repaired with the new system. Your alarm dealer will give you specific instructions on what to do. The alarm dealer will need to go to each PROINDMV zone within AN360, select EDIT, then select LEARN. At that point they will tell you to activate the Motion Viewer. You can either remove the cover, or remove and replace the batteries. The PROINDMV will then be repaired.
9. Thoroughly test each component including zones, keypads, keyfobs, communicators, etc. Use the system test mode.
10. It is now safe to add new PROSIX devices to the panel.
11. If you're using BlueTooth Disarming, all cell phones will have to be manually paired with the new panel.
12. If you used Alexa with the original panel, you'll need to set that up manually with the new panel.
13. All Z-Wave devices that were paired with the original panel will need to be excluded then included with the new panel.
14. All Total Connect 2.0 scenes will need to be recreated.

Resideo recently announced they would discontinue the Honeywell Home PROA7PLUS and would continue to produce the Resideo PROA7PLUSC. We now use PROA7PLUS and PROA7PLUSC interchangeably.
