DMP 464 Cellular Interface Card Now Available & Shipping

For customers wanting to upgrade legacy XR100 and XR500 panels, there is new firmware available from DMP to support these panels on the Verizon LTE network using the new 263LTE-V5 Cellular Communicator. Because the standard 263LTE-V unit is not compatible with the older XR100/XR500 panels, the 263LTE-V5 Cellular Communicator is designed specifically for this purpose. The new LTE Cellular Communicator is now available and will provide fully supervised alarm communication path over the Verizon LTE network. The 263LTE-V5 installs on the panel inside the enclosure and is powered by the panel so no additional enclosure, power supply, or battery back-up are needed.

Please note the Verizon LTE network does not support MyAccess messaging. Additionally, DMP is making available Model 464 (XR100/XR500 Cellular Adapter Board) for use when adding cellular communication to XR100 or XR500 panels when upgrading these panels that do not currently have cellular installed. The 464 Cellular Interface Card is now available for stand-alone purchase from DMP. Click here to see the installation guide.

For compatibility, the XR100/XR500 control panel firmware should be updated to Version 213 or higher. With the correct firmware, the LTE network connectivity provides the longest viable cellular lifespan available.

Please review the information available in this Installation Guide and Technical Update. If you have any questions, please contact DMP Inside Sales at 877-757-4367 or at
