Activating Or Deactivating Alarm Validation; Alarm Validation Times For The M300 - Dräger Infinity M300 Series Instructions For Use Manual

Activating or deactivating alarm validation

When alarm validation is enabled (see "Telemetry defaults > Alarms > Device settings tab" on page 214),
an alarm condition must exist for a certain period of time before audible and visual alarm signals are
triggered. This feature helps to reduce the number of nuisance alarms. The factory default for Alarm
Validation Delay is Off.
When alarm validation is enabled, the time between the detection and annunciation of a parameter falling
outside the set alarm limits equals the time of detection plus the assigned alarm validation delay. For heart
rate, adding the delay time may exceed the maximum of 10 seconds allowed by IEC 60601-2-27.
The following tables list which parameters have an alarm validation time. Parameters that do not appear
in the table have no validation times and audible and visual alarm signals are triggered almost
immediately.
