      When using the ASCII protocol to get alarm status from the panel the following message is received (spaces added for readability):

      1EAS 01010000 04041111 U0000000 00E3

      The “U” is not documented in the ASCII protocol documentation. The person reporting this issue says that they don’t (yet) have a battery on the panel, could the “U” stand for “unsupervised”?

        Are any of the Burg Zones in Area 1 in a Trouble State or programmed with “Periodic Trip” enabled?

          I’m unsure as the problem seems to have resolved. Can you clarify if “U” is valid in the ASCII Alarm Status message and what “U” stands for?

            So the problem has reoccurred and there is a zone in troubled state.
