9.1 Types of alarms

There are two types of alarms:
•
manual reset;
•
automatic reset: the alarm is reset and the unit restarts automatically
when the alarm condition is no longer present;
When an alarm occurs, the Alarm button flashes and the display shows
the standard display.
Press Alarm to display a short description of the alarm.
Press Alarm again to attempt to reset the alarm:
1.
if the cause is no longer present, the alarm should be reset and the red
light on the button will go off;
2.
if the reset attempt fails, the Alarm button stays on steady, signalling that
the alarm has been acknowledged.
If the alarm is reset automatically, the Alarm button goes off and the
alarm reset event is recorded in the alarm log.
Example: the high humidity alarm is visible in the list of alarms, and the
log shows the activation event (down arrow) and reset event (up arrow).
