Hi DIYers! We have great news for anyone clinging on to an old Honeywell LYNX Touch L5200 System. The panel now supports the use of a new Honeywell LYNXTOUCH-MSD Updater Tool and can be upgrade to the latest firmware. This means the L5200 can now use one of the LYNX Touch LTE Communicators!
This news was brought to our attention thanks to Resideo Technical Notification #43, which you can view here. According to this document, the L5200 can now receive a firmware upgrade from a newly released LYNXTOUCH-MSD Firmware Updater Tool. These newly released updater tools will have the following sticker on the box:
It is our understanding that any existing LYNXTOUCH-MSD Firmware Updater Tools WILL NOT work with the L5200. However, we are still awaiting word from Resideo regarding confirmation. We also believe that it will no longer be possible to have firmware updates pushed down to the L5200 over-the-air (OTA). Instead, all future updates for the L5200 must now occur using the updater tool. Please note that by upgrading the L5200 System to run the latest firmware, AlarmNet360 will view the system as an L5210 running the latest firmware. As far as AlarmNet is concerned, the L5200 and L5210 are the same system once the panel is on the latest firmware.
Update: Resideo confirmed that only LYNXTOUCH-MSD Firmware Updater Tools manufactured after October 2019 will work with the L5200.
The new updater tool will also continue to support the L5210 and L7000 Systems like normal. For more information on using the Honeywell LYNXTOUCH-MSD Firmware Updater Tool, please review this helpful FAQ. We offer step-by-step instructions and a video that will help you use the device to upgrade any Honeywell LYNX Touch System.
By upgrading to the latest firmware, you can use the LTE cellular communicators with the L5200 System. These include the Honeywell LTE-L57A (AT&T LTE) and the Honeywell LTE-L57V (Verizon LTE). Upgrading to LTE is crucial for extending the life of your security system. Please note that Firmware Revision 9.00.209 or higher is needed to use the LTE-L57A, and Firmware Revision 9.00.201 or higher is needed to use the LTE-L57V.
Remember that older cellular networks like AT&T 3G and 4G and Verizon CDMA are set to be shut down in the coming years. Meanwhile, support for LTE Networks will be maintained well into the very distant future! Remember that Alarm Grid customers will need a Gold Plan or higher to use cellular communication with any system.
Additionally, you might also need to update the firmware for your L5200 to use a newer Honeywell L5100-WIFI Module. Any L5100-WIFI module with any updated MAC prefix can only be used with a LYNX Touch System running Firmware Revision 8.00.183 or higher. If your L5200 is running an old firmware version, you can upgrade to the latest version using the newly enhanced LYNXTOUCH-MSD Updater Tool. This will allow you to use any L5100-WIFI Module with the system. More information on the L5100 MAC prefix update can be found in this blog post.
This is certainly great news for any L5200 owner, as the system has essentially been "resurrected", and can now be set up to use fast and reliable dual-path connectivity (LTE & WIFI) just like any top-of-the-line security system!
