Resideo has released several MyWebTech Technical Notifications this week. Technical Notification #119 announces a firmware update for PROSeries panels and PROWLTOUCH touchscreen keypads. Notification #121 addresses a firmware update for some legacy AT&T communicators. No action is required.

Technical Notification #119:

Technical Notification #119 announces a recommended firmware update for all PROA7, PROA7C, PROA7PLUS, PROA7PLUSC, PROWLTOUCH, and PROWLTOUCHC products. The panel firmware will be updated to version 03.2306.55, and the touchscreen keypads will be updated to version 3.424.34. This update improves WIFI connectivity between the panel and keypad.

It's important to remember that these panels cannot perform firmware updates using only an LTE cellular connection. A WIFI connection is required to download and install new firmware. This is why we strongly recommend installing a PROWIFI or PROWIFIZW module and connecting the panel to WIFI. If the panel won't use WIFI and you don't have touchscreen keypads, this update is not necessary.

Resideo is shipping updated units to their distributors. In the meantime, new panels will automatically receive any necessary firmware updates during activation and registration, provided a WIFI communication path is available.

If you have a PROSeries panel or touchscreen keypad, no action is needed. Resideo will automatically push the new firmware to all connected panels with a WIFI connection. The panel or keypad will reboot to install the update, so please be aware of this brief interruption.

In order to receive the firmware update, the product must meet this criteria:

• Have a WIFI connection.
• Be in a Disarmed state.
• AC must be present.
• Must not be in the process of reporting a signal.
• Must not be in Walk Test Mode or Programming Mode.

Technical Notification #121:

The products affected by this notification are a little more obscure. The models affected are the LTE-IA, LTE-IC (Canada), LTE-XA, LTE-XC (Canada), LTE-CFA (Commercial Fire), and HWF2A-COM (Commercial Fire, Dialer Capture). Alarm Grid currently does not sell any of these products.

The affected AT&T communicators will receive firmware update 20.00.549.1 and AppZone firmware HW.00.1-25. These updates improve cellular connectivity with the AT&T network.

This firmware addresses minor connectivity issues reported with these units. Resideo will begin pushing the update en masse on the week of February 24, 2025. You can also manually request the update by triggering a test. For the LTE-IA and LTE-XA, briefly pressing and releasing the tamper switch initiates a test. Commercial fire products have a test button near the center of the communicator board.

During and after the update, the communicator may report the following signals:

Contact ID Code	Description
E365	Cell Software Update Start
R365	Cell Software Update Finished
E366	Cell Software Update Failed

This is just a friendly reminder that the 3G and CDMA Sunsets are still on-track. The AT&T 3G Sunset occurs January 31, 2022, while the Verizon CDMA Sunset occurs December 31, 2022. Alarm Grid can help you take action and make a transition to newer LTE hardware, or make alternative plans.

The 3G and CDMA Sunsets go beyond the alarm industry. Older cellular technology is being shut down and will no longer work. This is being done to transition resources to newer and more advanced cellular technology that will provide more effective service for users. After the shutdown, only 5G and 4G LTE will remain active as major network bands. Once your alarm system is set up with LTE, you will have a trustworthy and reliable communication path for many years to come.

You may have to start thinking about the 3G or CDMA Sunset if you have an older alarm system that is still using a 3G or CDMA Communicator. By the time the Sunset occurs and the associated cellular network is shut down, you will either have upgraded to newer technology, or your hand will be forced and your system will no longer be monitored.

The following outcomes are possible for any user with a 3G or CDMA Communicator:

• Upgrade to a new alarm panel entirely, namely one that will support LTE, or a Honeywell Panel or Resideo Panel that is IP Only.
• Keep the existing alarm panel, and upgrade its 3G or CDMA Communicator to a new LTE Communicator that will allow it to stay monitored.
• Downgrade to IP-only monitoring service. This is not possible for any system that uses Alarm.com.
• Terminate all monitoring service for the panel. It can still be used as a local sounder, but it will not report signals.

Users with 3G and CDMA Communicators who do not take any action will be subject to that last option. Once the 3G or CDMA Network is shut down, the panel will lose network connectivity, unless it is a Honeywell Panel configured for internet connectivity. A system that loses all connectivity due to a permanent network shutdown can still be armed and disarmed, but it cannot send any signals to the central station, meaning that no help can be automatically dispatched. The system also won't send notifications to Alarm.com or Total Connect 2.0, and the user won't be able to control their system remotely from one of those platforms. Also, the user will not be able to maintain an active Certificate of Alarm (CoA) for a discount on their homeowner's insurance. Only actively monitored systems are eligible for a CoA.

Many users aren't even aware that their systems have 3G or CDMA Communicators that need to be upgraded. There are ways to tell if your communicator needs to be upgraded, but it may be difficult for someone who isn't trained to tell. If you have an older security system that you think may be in need of a communicator upgrade, then we can help you. Reach out to our team at support@alarmgrid.com, and we will work with you to make sure that you are ready for the 3G or CDMA Sunset. Depending on your situation and the equipment, we will advise you to do one of the following.

• Upgrade to a panel that can support LTE Cellular.
• Upgrade the communicator for an existing panel to LTE Cellular.
• Certain Honeywell Panels can be downgraded to support IP-only so that you can stay monitored using the equipment you already have.

Do you have any questions about the 3G or CDMA Sunset? Maybe you have already upgraded, and you want to let us know about your experience? Or maybe you have been putting off upgrading and are waiting until the last minute? We would love for you to leave a comment down below to let us know how you are preparing for the 3G or CDMA Sunset in your home or business. This is a major event for the security industry, and it's happening very soon. Stay tuned to the Alarm Grid blog for more security news and updates on the 3G and CDMA Sunset, as we all transition to LTE.

Security, Sales, & Integration recently published an article outlining the 3G Sunset and the importance of upgrading to LTE. One question we are often asked is how long LTE networks will be kept in-service. Thanks to this informative article from SSI, we now have a pretty good estimate.

According to the information presented in the article, LTE networks are expected to have a lifespan that extends through at least the mid-2030s, if not longer. We have said many times before that LTE networks should be kept in service well into the very distant future, and now we have somewhat of a more precise timeline. It is also important to note that we understand this "mid-2030s" estimate to be on the conservative side. There is a good chance that the LTE networks might be supported even beyond that point in time. But given that we are in the year 2020, and have a "mid-2030s" estimate for the LTE lifespan, we can say that anyone who purchases an LTE communicator for their security system at this point in time should expect it to work for at least the next 15 years.

We need to stress here that this is nothing official. This is just information being published in an SSI article. This is not an official statement from a cellular service provider, and we advise taking it with a grain of salt. But given our understanding on the subject, this mid-2030s estimate strikes us as legitimate. The article also states that all 3G cellular networks will be shut down no later than December 31, 2022. This also lines up with what we have been hearing. At the time of this writing in late October 2020, we are slightly more than two (2) years away from the final end of 3G. We have said it many times before, and we will say it again. You need to upgrade to LTE as soon as possible to avoid a loss of monitoring service.

On that note, it's also fair for us to begin thinking about what lies beyond LTE. It's no secret that 5G networks are being rolled out across the country, and they will soon become the norm for cellular communication. At this time, we have not heard of any alarm manufacturer offering a 5G communicator, though we wouldn't be surprised for it to happen soon. But it's not a sure thing that a 5G communicator would be available before the end of 3G. That is why we are pushing so hard for users to make the upgrade to LTE. We don't want any of our monitored customers to be left behind in the transition. While the eventual promise of 5G might seem exciting and flashy, the important thing here is keeping your security system working and having your home or business stay protected. And from what we can tell, LTE will provide exactly that until at least the mid-2030s, possibly even beyond that.

If you are interested in getting starte with alarm monitoring service, or if you are needing to upgrade your existing system to LTE, please email us at support@alarmgrid.com. Our team is here to check email from 9am to 8pm ET M-F. We look forward to hearing from you!

It's Monday again, and it's time for another Alarm Grid video recap! We have six (6) new videos for you. Five (5) feature the DSC PowerSeries NEO, while the last one covers the Honeywell LTE-IA and LTE-IV Communicators for VISTA Systems. All videos feature yours truly. Let's check them out!

Adding a DSC HS2TCHP Touchscreen Keypad to a DSC PowerSeries NEO

I show you how to add a DSC HS2TCHP Touchscreen Keypad to a DSC PowerSeries NEO Security System. Adding a touchscreen keypad like the DSC HS2TCHP to a system can be more inviting and easier for end users to understand than a traditional numeric keypad. The DSC HS2TCHP connects with the same on-board panel terminals as any other keypad for the system. Remember to power down your NEO Panel completely before adding a keypad or making any other hardware changes.

Adding Hardwired Zone to DSC PowerSeries NEO Security System

I show you how to add a wired sensor to a DSC PowerSeries NEO Security System. As a hardwired alarm panel, the DSC PowerSeries NEO can used wired sensors with no extra add-ons being required. All wired zones on the NEO will use end of line 5.6k ohm resistors, which are color coded green-blue-red-gold. This includes wired zones that are not actively being used with the system. New wired sensors will be connected with the panel, and the appropriate Zone Definition will be set at the corresponding zone.

Program a Wireless Zone to a DSC PowerSeries NEO

I show you how to add a wireless sensor to a DSC PowerSeries NEO Security System. The NEO cannot support wireless sensors right out of the box. Instead, a wireless transceiver must be added to the system. The NEO supports PowerG Transceivers that will allow you to use PowerG Wireless Sensors with the system. The advantage to using wireless sensors is that they are much easier to install than wired sensors. This is because you will not need to run wires for wireless sensors.

Enrolling a PowerG Sensor to a DSC PowerSeries NEO

I show you how to add a PowerG Sensor to a DSC PowerSeries NEO Security System. This will require that a PowerG Transceiver is added to the system, such as a DSC HS2LCDRF9 N Keypad or a DSC HSMHOST9 Standalone Transceiver. PowerG Sensors are widely seen as some of the best wireless sensors in the security industry. This is because these sensors offer a wireless signal range of up to 2km in an open air environment, and they utilize military grade 128-bit AES encryption for exceptional security.

Delete a Zone From a DSC PowerSeries NEO

I show you how to delete a zone from a DSC PowerSeries NEO. This process differs depending on whether the zone is wireless or hardwired. For a wireless zone, you are clearing the sensor from the system so that it is no longer recognized. For a wired zone, you are merely changing the Zone Definition for the associated wired zone to [000] for Null Zone. Deleting a zone from a DSC PowerSeries NEO will open up the zone so that it can be used with a different sensor.

Installing a Honeywell LTE-IA or LTE-IV Communicator to a VISTA-21iP System

I show you how to add a Honeywell LTE-IA or a Honeywell LTE-IV to a Honeywell VISTA-21iP Security System. The LTE-IA and the LTE-IV are dual-path communicators that use both IP connectivity (wired ethernet) and LTE cellular connectivity. When adding one of these communicators to a VISTA-21iP, you must first disable the internal IP communicator for the system. This is done by re-positioning the white jumper to the bottom two (2) prongs. Make sure to power down the panel before re-positioning the jumper and installing the communicator!

We're here once again to remind you to upgrade the old 3G or CDMA cellular communicator for your alarm system to an LTE communicator! Once the associated cellular network is shut down, the old communicator will no longer work in any manner. This could leave your home or business vulnerable!

Security systems use internet and/or cellular communication to send out signals to central monitoring stations and/or interactive monitoring platforms like Total Connect 2.0 and Alarm.com. This is the very core principle of alarm monitoring. And if the associated communication network is shut down or fails, then alarm monitoring will become impossible.

Just like your phone, tablet, or computer, your alarm system cannot just magically send out signals. It needs equipment to accomplish this task. That equipment comes in the form of an alarm monitoring communicator. This is a piece of hardware either inside, or located nearby your alarm panel, much like what you would find inside of another electronic device that needs to communicate out and also receive incoming signals.

In the world of cellular communications, you have likely heard about the new 5G networks. These 5G networks represent the latest and greatest cellular technology available, and they are certainly going to change the game when it comes to mobile communication. But while service providers are working to develop new 5G infrastructure, they are also phasing out older technology. This includes the AT&T 3G Network and the Verizon CDMA Network.

If you have a system with a cellular communicator that works across a 3G network, such as the aforementioned AT&T 3G and Verizon CDMA Networks, then time is running out for you to upgrade. While we cannot provide an exact date of shut down, we can confirm that it is due to occur sometime in 2022.

Now, you might be thinking, "Well gee, 2022 is a long way away. I'll just wait until then." And really, we can't force you to upgrade now. We have already promised to continue supporting older communicators for as long as possible. But if you have the means to buy a new cellular communicator and keep your existing system running, then we urge you, as professionals, to make the jump sooner rather than later.

Time is moving quickly, and we can all but guarantee you that some people will not get the memo, and they will get left behind. We understand. For many people, a security system is not something that is on their minds regularly. Historically, this has been a piece of hardware that you hide away somewhere, while only interacting with a wired keypad. But don't take this deadline lightly. Make the jump sooner rather than later, and save yourself the trouble.

We are also often asked by people upgrading from 3G or CDMA which type of communicator they should get. The answer to that is an LTE communicator. LTE is the direct successor to 3G and CDMA. If you have heard the term "4G LTE", that's where LTE comes from. There have been LTE communicators available for security systems for a few years now. They work great, and they can keep a system monitored well into the very distant future.

You might be wondering why we aren't recommending a 5G alarm monitoring communicator. The truth is that 5G technology is still so new that there aren't really any 5G communicators available quite yet. We are sure that we will have some 5G communicators available to sell and promote in the near future. But for right now, LTE is the best available. And since LTE already provides fast speeds, there really won't be much difference for a security system.

Another common concern we encounter is that end users are fearful that LTE will also one day become obsolete. Our response to this concern is that LTE will most likely remain active and in place for many, many years, even decades into the future. The term LTE itself even stands for "Long Term Evolution". Cellular service providers envision 5G as the primary network of the future, with LTE infrastructure being kept in service as a reliable backup.

It's important to understand that building a new nationwide cellular network is not cheap. Every cellular service provider is spending billions to build the necessary infrastructure. To them, this is not a joke or a game. The 5G networks are being built to last. They enable the remarkably fast speeds needed to support future technology. The idea here is that they are spending huge amounts of money now so that they do not need to build new networks later.

And while 5G cellular networks are the technology of the future, the current LTE networks are also not going anywhere anytime soon. Why? They are designed to serve as backup options once 5G is fully in place. This is much like the current 3G and CDMA networks. They are a backup to the current LTE networks. If you have ever noticed that your LTE phone is also capable of using 3G, that is why. It's in case LTE is ever unavailable for some reason.

The difference with 5G is that, once in place, it is going to be the premier option for a very, very long time. The very idea of a supposed "6G network" isn't really even fathomable at the moment. We're likely talking decades from now. What you can expect in the near future is that 5G will become the primary technology, while LTE will be kept in-service as a backup.

And again, we hear some more cries from people, "Well, I'll just wait for a 5G communicator to come out." The truth is that with alarm systems, the difference between LTE and 5G really won't matter all that much. Security systems do not transmit large amounts of data. Yes, 5G might make some automation commands a hair faster. But LTE can already handle this quite well. And it's very possible that 5G communicators might not be ready before the 3G sunset.

Long story short, you should upgrade to LTE as soon as you can if you intend on using cellular communication with your security system. Remember that cellular service is much more reliable than WIFI connectivity. Even in the year 2020, internet outages are relatively common. They likely always will be. That is why users are willing to pay a premium for cellular monitoring service. Cellular all but ensures your system will always stay connected.

While your 3G or CDMA communicator might be working great right now (as it always has been), you will wake up one day (in 2022) only to find a scary "Comm Fail" message with no quick solution. And if you are cell-only, your panel will be offline, and your home or business will be vulnerable. Don't let that happen. Just make the jump to LTE as soon as you can.

Alarm Grid offers LTE cellular communicators for many types of alarm systems. We can help you get exactly what you need so your transition is as seamless as possible. As of this writing, there won't be any increase in your monthly bill. You will pay exactly the same monthly fee for cellular monitoring service using a new LTE communicator as what you pay with a 3G or CDMA communicator now. You only need to buy the new LTE module. That's it.

And if you're worried about needing to install your new LTE communicator, fear not! These devices are super easy to install. And if you're monitored by Alarm Grid, we will be more than happy to help you through the installation process. That's our job. Every day, we encounter new and inexperienced users and help them monitor their homes and businesses. And that includes keeping existing systems running. We love what we do, and we're happy to help.

Maybe you aren't sure which LTE communicator you need for your system? Hey, we totally understand! It's not like you're completely obsessed with this stuff (like we are). Just shoot us an email with a picture of your panel, and we can help you explore your options. If you can get us a picture of the panel's inside with its current communicator, then that's even better!

Like always, the best email to reach us is support@alarmgrid.com. We'd love to hear from you, whether you're an existing Alarm Grid customer, or if you're looking for the very best in DIY security. Maybe you would prefer to talk on the phone? That's cool too. Our number is (888) 818-7728, and we happily answer phones from 9am to 8pm ET Monday thru Friday.

Our goal is to make the 3G and CDMA sunset as easy and as seamless for our customers (and future customers) as possible. The time to take action is now. We can help you get what you need so that you and the people around you stay safe and protected. The 3G sunset is serious, and we don't want you to get left behind. Please, upgrade now. We are grateful to have you as a member of the Alarm Grid family, and we look forward to hearing from you.

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:

Contact ID	Description
E365	Cell Software Update Start
R365	Cell Software Update Finish
E966	Cell Software Update Failed
E903	Code Update Start
R903	Code Update Finished
E904	Code Update Failed
E339	Power On Reset

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!

Hi DIYers! We have exciting news today, as the Honeywell LTE-IA for VISTA Series Panels is now available! This has been eagerly anticipated by VISTA users with strong service from the AT&T LTE Network. We are sure that many of you will want to take advantage of this great new communicator!

As a dual-path communicator, the Honeywell LTE-IA can send signals thorough both a local IP network and a cellular network. It uses a hardwired ethernet connection for IP service, and it works across the AT&T LTE Network for cellular service. The communicator will use IP as its primary path, and cellular will serve as the backup.

Being able to connect with the AT&T LTE Network is the best feature of this communicator. AT&T has stated that they will support their LTE network well into the very distant future. The network will remain in-service even as newer networks like 5G are made available many years from now. AT&T invested huge amounts of money into their LTE infrastructure. Their LTE network is not going anywhere anytime soon. The result is that this communicator will keep your VISTA Panel monitored in the long-run.

The importance of reliable cellular backup cannot be stressed enough. Internet outages, and it is highly likely that your system will need to rely on its cellular connection at some point or another. As long as the cellular path is still available, your VISTA System will remain connected with the AlarmNet360 Servers. This means that you will still be able to take advantage of all the great features from Total Connect 2.0.

Speaking of Total Connect 2.0, a proper AlarmNet Communicator like the Honeywell LTE-IA is required if you want to use this service. If you didn't know, TC2 is an interactive monitoring and automation platform that you can access from anywhere. This is possible using the Total Connect 2.0 Mobile App on Android and iOS devices.

By accessing TC2, you can arm and disarm your system, check its status, control Z-Wave devices (Tuxedo Touch or VAM required), view TC2 Cameras (video plan needed), and more. All you need is a compatible Honeywell System with an AlarmNet Communicator, and an appropriate alarm monitoring plan.

For the VISTA P-Series Panels, the VISTA 15P, VISTA 20P, and VISTA 21iP can all support TC2. There are just some firmware requirements you need to keep in mind. A 15P or 20P must be running firmware 9.12 or higher. A 21iP must be running firmware 3.13 or higher. If you aren't sure of the firmware, just check the PROM Chip. This is a small black chip on the panel's main board. It will have a code that begins with the letters "WA". This code will tell you the firmware version.

If you find that the PROM Chip is not high enough, don't worry! We sell new 15P PROM Chips, 20P PROM Chips, and 21iP PROM Chips. Just be aware that a 15P or 20P System will need to be at least firmware 2.0 or higher to receive a PROM Chip upgrade. Any VISTA 21iP can receive a PROM Chip upgrade.

To replace the PROM Chip, start by powering down the panel by disconnecting the backup battery and unplugging the transformer. Carefully pry off the old PROM Chip with the metal end of a binder clip. Then apply the new one by putting it in the same place and pressing it down until it clicks. Just be careful not to bend the metal prongs on the new PROM Chip! You can then power up your system by plugging the transformer back in and reconnecting the backup battery.

If you actually have better service from the Verizon LTE Network than the AT&T LTE Network, you should also know that a similar Verizon LTE Dual-Path Communicator called the Honeywell LTE-IV has been available for quite some time. Remember, the service provider for your alarm system has nothing to do with the service provider for your phone. Just go with whichever service works best in your area, regardless of which service you use for your smartphone.

If you have any questions about the Honeywell LTE-IA, please reach out to us. The best way to contact us is to email support@alarmgrid.com. Another option is to call us during our normal business hours of 9am to 8pm EST M-F at (888) 818-7728. We look forward to hearing from you!
