There are three types of alarm resets:
— Auto: automatic, when the event causing the alarm stops, also the alarm disappears.
— Semi (semi-automatic) = the alarm is automatic, but if it is triggered more than 3 times in an hour then it becomes with manual reset;
— Manual: manual, to restart normal operation manual acknowledgement is necessary.
