      If your DSC Cell Phone shows a Yellow LED flashing two times, it indicates a panel supervision trouble. Check that section [382] toggle option [5] is ON (Alternate Communicator Enabled). Also, make sure the PC-LINK cable between the panel and communicator is connected properly (not reversed) and is securely in place.

      If your DSC Cell Phone displays a Yellow LED flashing 12 times, it indicates a module configuration trouble. This usually means that the system account code in section [021] or the receiver account code in sections [101] or [111] has not been programmed. Make sure a valid account code has been entered in these sections.

      Jennifer StoneAug 25, 2025
      If the DSC Cell Phone has a Yellow LED flashing 7 times, it means the receiver is not available. Ensure that the Ethernet path has Internet connectivity. If you are using a static IP address, verify that the gateway and subnet mask are entered correctly. If your network uses a firewall, ensure that the programmed outgoing ports are open (default UDP port 3060 and port 3065). Also, ensure that all receivers are programmed for DHCP or have the correct IP address and port number.
