technical bulletin
Neither the annunciator E2 nor any of the non-annunciators will keep notification of where
the advisory acknowledgement originated from.
A Reset All Advisories command (
) also works from either the annunciator log or
the non-annunciators advisory log.
Resetting Advisories
Advisories may be reset from either the annunciator log or from the non-annunciator E2
from which the advisory originated. In either case, a reset advisory is marked as reset in both
the annunciator log and the non-annunciator E2 log.
Any time one or more advisories are reset, the E2 will write an advisory in the log of the E2
from which the advisory originated, indicating (1) one or more advisories were reset, and (2)
where the reset command was issued. The advisory text will show the origin of the reset
command:
Alarm(s) were reset - The reset command was issued from the front panel of the E2 that
originated the alarm (or from a Terminal Mode user connecting to this unit).
Alarm(s) reset from Remote - The reset command was issued from a user connecting
with UltraSite32. A reset command from Terminal Mode does NOT cause this advisory
message to occur.
Alarm(s) reset from Annun - The reset command was issued from the front panel of the
alarm annunciator (or from a Terminal Mode user connecting to the annunciator).
A Reset All Advisories command (
) also works from either the annunciator log or
the non-annunciators advisory log. If a Reset All Advisories is requested from the alarm
annunciator, the Alarm(s) reset from Annun notice will only be written once for each non-
annunciator E2 that had advisories reset by the operation.
Clearing Advisories
Advisories may be cleared from either the annunciator log or from the non-annunciator E2
from which the advisory originated. In either case, a cleared advisory is erased from both the
annunciator log and the non-annunciator E2 log.
Any time one or more advisories are cleared, the E2 will write an advisory in the log of the E2
from which the advisory originated, indicating (1) one or more advisories were cleared, and
(2) where the clear command was issued. The advisory text will show the origin of the
cleared command:
Alarm(s) were cleared - The clear command was issued from the front panel of the E2
that originated the alarm (or from a Terminal Mode user connecting to this unit).
Alarm(s) cleared from Remote - The clear command was issued from a user connecting
with UltraSite32. A clear command from Terminal Mode does NOT cause this advisory
message to occur.
