Red - Presently in alarm status.

Green – The cause of alarm status was temporary, and has now returned to normal.

Grey – A temporary alarm (in green status), after having been acknowledged, then becomes grey.

Active Time is the time that alarm status becomes active. Clear Time is the time when two conditions are met. Firstly alarm status is cleared and becomes normal, and secondly the user has acknowledged it. Once an alarm occurs, the red buzzer icon on the top right starts flashing. After the cause of alarm is no longer met and the alarm is acknowledged, then the red buzzer icon disappears. When Clear Time shows Terminated this indicates that the alarm has been terminated by turning off the power.
