Resideo Technologies recently released a technical notification (TN #69) outlining an issue with the CELL-ANT3DB External Antenna kits. It seems that for some time, these kits have included an incorrect mounting bracket. Without the correct mounting bracket, proper mounting is not possible.

Update provided by Resideo!

The Resideo CELL-ANT3DB External Antenna kit is an outdoor rated antenna kit that supports a number of different cellular frequency bands. In addition to simply moving the antenna from the mounting location of the radio to a location outside, the CELL-ANT3DB also provides up to 3dB of signal gain to improve cellular reception for the AlarmNet communicator.

To resolve this issue, Resideo has released the technical notice listed here. All current stock has been called back and reworked to have the incorrect bracket replaced with the correct one. If you are purchasing a new CELL-ANT3DB, you can check the barcode sticker on the box. If there is a Green Dot on this sticker, the product has been through the rework process and has the correct bracket.

If you recently purchased a CELL-ANT3DB from Alarm Grid and you believe your product has the incorrect bracket, contact us at support@alarmgrid.com and we will verify whether your product is affected, and will arrange to have the correct bracket shipped to you if it is. The information in the technical notice is lacking a bit, so in addition we've contacted the product manager to see if we can get some more data on either date codes affected, or images that show us what the incorrect bracket looks like, as opposed to the correct bracket. We will update this post with more information when/if it becomes available.

Update September 28, 2021

We heard from Resideo today that this issue affects a very small number of units. This error occurred on only three (3) days of production. Date codes E215, E222, and E223 are the affected production days. You can see the date code in the image above. It shows E256. If you purchase a CELL-ANT3DB Kit with one of the affected date codes, and the box has the green circle sticker mentioned and shown above, then your product is good to go. If you purchase a product with date code E256 or later, whether it has a green dot or not, the product is also good. If you purchase a product with date code E215, E222, or E223, and it does not have the green dot sticker, then you need to request a replacement mounting bracket.

Alarm Grid is offering new Alarm.com System Enhancement Modules (SEMs) for Honeywell VISTA P-Series Alarm Panels. The ADC-SEM300-VT-AT (AT&T LTE & IP) and ADC-SEM300-VT-VZ (Verizon LTE & IP) are both available now. They provide reliable alarm monitoring and Z-Wave Plus capabilities.

If you aren't familiar with Alarm.com System Enhancement Modules (SEMs), they are basically cellular communicators that allow hardwired alarm panels to connect with the Alarm.com servers. The reason why SEMs for Honeywell VISTA Systems are so interesting is because normally these Honeywell-manufactured Alarm Panels are used in conjunction with the Resideo AlarmNet Servers and the Total Connect 2.0 Security Notification and Automation Platform. With an SEM, you can take control of your Honeywell VISTA Alarm Panel and instead have it communicate with the Alarm.com servers and the Alarm.com platform. Alarm Grid customers can choose from a variety of alarm monitoring plans to use with SEMs, including our Gold and Platinum Level Plans (Self & Full) and our Cellular-Only Plan. You can learn more about all our monitoring plans in this comprehensive blog post.

When you break-down what Alarm.com offers versus Total Connect 2.0, both platforms are remarkably similar. However, there are some cases where a user may prefer to go with Alarm.com over Total Connect 2.0. The biggest reason why we can think of is that the user wants to take advantage of the robust selection of Alarm.com Security Cameras. If you compare the selection of Alarm.com Cameras versus the Total Connect 2.0 Camera Selection, then it's clear that Alarm.com is (at least for now) the hands-down winner. Even if you aren't using security cameras in your setup, maybe you want a better integration with the Alarm.com Smart Water Valve, or maybe there's an Alarm.com Demand Response Program in your area that you want to take advantage of. In any case, if you have a VISTA P-Series Panel (e.g. VISTA-10P, VISTA-15P, VISTA-20P, VISTA-21iP, VISTA-21iPLTE), then an Alarm.com SEM will give you the option of using their services instead of AlarmNet and TC2.

When you compare the new "300-Series" SEMs with the previous VISTA SEMs, the ADC-SEM210-VT-AT and the ADC-SEM210-VT-VZ, the new ones have a couple of advantages. For one, the new 300-Series SEMs utilize much lower power consumption at just 230mA. The new modules also have the ability to be used without an external power supply, which was required with the older modules. In the setup without an external power supply, all of the power is supplied from the panel. However, you can still use an external power supply with the new SEMs if you do not have 230mA available from your panel. Also, the new 300-Series SEMs have new externally-facing LED status lights that are easier to read when needed.

Just like the prior editions, the new ADC-SEM300-VT-AT and ADC-SEM300-VT-VZ offer ultra-reliable connectivity across both an LTE cellular network and internet service using a wired ethernet connection. In addition, the new SEMs also return with Z-Wave Plus functionality, thereby allowing you to build a robust and complete smart home network around your security system. If you have been wanting to setup smart devices around your Honeywell VISTA Alarm System for use around the Alarm.com Security and Automation Platform, then these new SEM devices are perfect for the job at-hand. They are available right now and ready for use with Alarm Grid!

Do you have any thoughts about the new Alarm.com 300-Series SEMs, the ADC-SEM300-VT-AT and ADC-SEM300-VT-VZ? Would you consider switching over your Honeywell VISTA System to the Alarm.com Platform from Total Connect 2.0? Or maybe you're already happy with using your VISTA System with its current LTE cellular communicator? Let us know your thoughts in a comment down below. We would love to hear what you have to say. We always make sure to cover new product releases and the latest security system news, so make sure to stay tuned to the Alarm Grid Home Security Blog for more great content coming soon!

There is going to be scheduled maintenance occurring on Alarm.com tonight, specifically focusing on the Verizon infrastructure. The maintenance period will run from 12:00 am Midnight to 2:00 am Eastern Time. According to Alarm.com, no impact is expected with regard to monitoring service.

The purpose of the scheduled maintenance is to enhance platform stability and improve redundancy moving forward. We have heard reports that a small number of Alarm.com Verizon LTE Communicators have been experiencing some relatively minor technical issues. Alarm.com has been aware of these issues since at least last Saturday, and they have been actively working to troubleshoot affected units to prevent any disruptions in service. The scheduled maintenance tonight should fix these issues and help to ensure that all Alarm.com Verizon Communicators function as intended, with exceptional reliability.

During the scheduled maintenance period tonight, Alarm.com says that service outages are unlikely to occur. You should not experience any problems if your security system uses a Verizon Communicator for connecting with Alarm.com. However, Alarm.com is not ruling out the possibility, and they want to keep users informed, just in case. Remember that if you have an IP (WIFI or Ethernet) communication path set up, then that can serve as a valuable backup option tonight during the maintenance period. If your system is cellular only with Verizon connectivity, then just be careful if you need to arm your system tonight between 12:00 am Midnight and 2 am Eastern Time. Again, no issues should occur, but Alarm.com is performing due diligence by making the maintenance period known in advance.

Once again, all maintenance taking place is on the Verizon infrastructure for Alarm.com. Your monitoring service will not be affected in any way if your system uses a different carrier, such as AT&T, for connecting with Alarm.com, or if your system is set up with a different network, such as AlarmNet for Total Connect 2.0, or Telguard for HomeControl Flex. If your system does use Verizon connectivity for communicating with Alarm.com, then check and make sure your WIFI or Ethernet path is working as an important backup plan for tonight. If you have been using your system with cell-only on Verizon with ADC, but you have the option to add WIFI or Ethernet, now may be a good time to do so. Your system should still be fine, but, it never hurts to use redundancy when it is available. Stay tuned to our blog for more security system news and updates coming soon.

Note: If you are reading this after 2:00am on April 14th, or on any future date, then it is assumed that the scheduled maintenance has been concluded, and all Alarm.com Verizon Service should be operating as intended, now with improved infrastructure.

We have learned that Verizon has confirmed the sunset date for their CDMA Network for December 31, 2022. This is Verizon's equivalent of the 3G Sunset. Anyone with a security system using a Verizon CDMA Communicator is urged to upgrade to LTE ASAP to avoid monitoring service disruptions.

The 3G Sunset has been covered extensively on the Alarm Grid Blog. It refers to the phasing-out of old 3G and equivalent communicators, in favor of newer technology, specifically LTE. The Verizon CDMA Network is the Verizon equivalent of a 3G Network. While AT&T is known to be shutting down their 3G Network after January 31, 2022, the Verizon CDMA Sunset date it a bit later at December 31, 2022. While there was earlier confirmation by Resideo for the CDMA shutdown date, this time the confirmation is directly from Verizon themselves.

In preparation for this major event, Alarm Grid has been encouraging users to replace their old 3G and CDMA Communicators with newer LTE communicators. Users are strongly advised to upgrade to LTE as soon as they can. While it's understandable to wait until the last minute, especially if money is tight, you should realize that many other users will also try to wait until the final opportunity. Our support staff is limited, and we cannot upgrade everyone all at once. If you put-off the required upgrade as long as possible, then there's a chance you might get left behind at the deadline. Our goal is to prevent that from happening and ensure that all Alarm Grid customers with cellular monitoring service make a seamless and undisrupted transition.

We know that the 3G Sunset might still be a bit confusing, and you might still have some questions. That's okay, because we're here to help you. If you aren't sure about the LTE communicator replacement options available for your system, then you may want to check this post for some further assistance. If you have recently purchased a new LTE communicator for your system, and you need us to activate the unit, then head on over to the Alarm Grid Communicator Replacement Portal so that you can choose a time that works for you. And if you have any other questions, or if you are still confused about the 3G and CDMA Sunset, please email our support team and security system experts at support@alarmgrid.com. We're here to answer your emails from 9am to 8pm ET M-F. We look forward to hearing from you!
