Maybe you could post that section of the log... any zone info at that time? Could not produce that error on some simple exit tests...
There's this note in the manual which might help:
Exit Error If an entry/exit zone is violated when the Exit Delay expires, the Exit Error Feature will be activated. The
local siren will sound immediately and the Entry Delay warning will begin. IF the control is not disarmed before the
delay expires the communicator will report the alarm along with an Exit Error code, provided these codes are
programmed. An Exit Error event flag will also be set which can be used by the “Whenever/And/Then” rules (refer to
the ELK-RP software) to sound a siren, or blink a light, or whatever. Exit Error complies with SIA CP-01. †
Exit Error Code can be used to identify an accidental alarm caused by an error while
arming. Locally, it works as follows: If an exit delay rolls directly into entry delay as a
result of a zone being left violated, the entry delay warning AND the siren will sound. If the
control is not disarmed prior to the entry delay expiring, the communicator will report the
alarm along with the Exit Error code. Range is 00 to FF. Default is 00 (no report).
