The first step in managing an alarm condition is to acknowledge the alarm. Acknowledging
an alarm does two important things:
•
It records the time and date at which you observed the presence of the alarm and stores
that information in the system’s historical log.
•
If multiple alarms are present, the system displays specific data for the next alarm when
you press the <FIRE ALARM ACK> key.
