Cellular Antennas Posts

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.

LTE cellular communication for the Honeywell LYNX Touch L5210 and L7000 systems is now available! The Honeywell LTE-L57V will provide these systems with ultra fast and reliable cellular service from the Verizon LTE network. The new module is easy to install, and it will ensure that these compatible systems receive cellular connectivity well into the distant future. Overall, we strongly recommend this module for any Honeywell L5210 or L7000.

Alarm Grid has long-touted the benefits of cellular communication. It sends out signals very quickly, and it is the single most reliable way to ensure that a Honeywell security system always remains connected to the AlarmNet server. LTE service represents the forefront in cellular technology, and the Verizon LTE network is one of the finest.

The Honeywell LTE-L57V provides the L5210 and L7000 systems with a way of connecting to the Verizon LTE network so that they can receive active cellular monitoring. This makes the LTE-L57V the prime option for anyone looking to "future-proof" their L5210 or L7000. Unlike the 3G and CDMA cellular networks, the LTE network should be in service well into the distant future, thereby providing a longer lifespan of the cellular alarm system.

In order to use the LTE-L57V, firmware revision 9.00.201 or higher is required. Any newly purchased L5210 or L7000 should already have the latest firmware update out of the box. Thankfully, existing L5210 and L7000 panels can be updated using the LYNXTOUCH-MSD Firmware Updater Tool.

The LTE-L57V is available for purchase now on the Alarm Grid website! Additionally, we will soon be updating our L5210 and L7000 bundled kits to include this module as well. At the present time, we have not heard anything about a possible AT&T LTE module for the LYNX Touch Systems. However, we will be sure to keep you posted and let you know if any information is available.

Update: The AT&T LTE Version is also available! It is called the Honeywell LTE-L57A. The LYNX Touch Panel must be running firmware revision 9.00.209 or higher to support the module.

Another Update: The L5200 can also be updated using the LYNXTOUCH-MSD Firmware Updater Tool. This will allow an L5200 System to use either the LTE-L57A or the LTE-L57V. More information is available here.
