An XR500E panel communicates using AES encryption. If you currently have an XR500N panel installed, you may contact DMP Customer Service with the panel serial number. The serial number(s) should be sent in writing via e-mail or fax. A separate feature key is sent for each panel to activate encrypted communications using the Feature Upgrade process. Encrypted communication cannot be enabled on a standard XR500 panel. For more information on the Feature Upgrade process see the XR500 Series Programming Guide (LT-0679)
Note: XR500N/XR500E only
