Testing Alarms
In general, to test the functioning of visible and audible alarms, do the following:
1 Enable the alarm.
2 Set the alarm limits.
3 Measure or simulate the parameter that is out of range, or signal loss.
4 Verify that the visible and audible alarms are working.
As an example, to test the FHR alarms:
1 Connect the US transducer to a fetal sensor socket.
2 Enable the FHR alerting (see “Turning Alarms On or Off ” on page 127).
3 Set the high alert limit and delay to 150 bpm and 60 seconds respectively, and the low alert limit
and delay to 110 bpm and 60 seconds respectively (see “Changing Alarm Limits” on page 127).
4 Generate a fetal heart rate of approximately 180 bpm (3 beats per second) for more that one
minute.
5 Verify the functioning of the visible and audible alarm.
Alarm Behavior at Power On
Selecting AlarmsOffAtStart will cause alarms to be initially suspended or off the next time the monitor
is switched on (depending on the setting for Alarms Off). The Alarms Off as Infinite behaves in the
same manner as when Alarm Mode equals INOP Only.
In order for alarms to be suspended or switched off initially, the monitor must be switched off for
more than one minute, the last main alarm state was set to off or suspended.
The exception to this condition is when the alarms off state has been set to Infinite, and the new active
setting is set to Infinite.
