5 ALARMS AND MESSAGES
Alarm Validation
The alarm validation feature minimizes nuisance alarms for transient conditions.
When a parameter value falls below or rises above its current alarm limits, the monitor
waits a predetermined time before triggering the alarm. If the parameter value returns
to within the upper or lower alarm limit before the end of the alarm validation period,
the monitor does not trigger the alarm.
The alarm validation period is part of the software (see table below) and cannot be
modified. The monitor triggers the alarm at the end of the validation period.
Parameters have the following alarm validation periods:
