At present, when a UTRED30-WiFi, UTRED30-16, UTREL30-WiFi, or UTREL30-16 unit triggers an alarm, both the buzzer and LED will activate. However, they stop as soon as the measured temperature returns to the acceptable range. The intended behavior is for the buzzer and LED to remain active until the alarm is manually cleared.
Please note that the cross and day markers on the LCD, as well as alarm processing via LogTag Online, are functioning as expected.
There is currently no workaround for this issue.
LogTag will be releasing a firmware update to address this issue.
