Alarms
Automatic delaying of acoustic and optical alarm signals
If the user switches on the device or changes settings that will probably result in
alarms, the acoustic and optical alarm signal for some alarms will be automatically
delayed. Whenever the settings are changed, the device checks whether an alarm
condition exists. The device delays the output of the alarm signals for as long as it
takes for it to reach the new values set by the user.
Example: The device is switched on when the room temperature is 23 °C (73.4 °F).
An air temperature of 36.5 °C (97.7 °F) is set. For the period that the device was
switched off, the current air temperature in the incubator was the same as the
ambient temperature and lower than the set value. The device detects the warm-up
phase and automatically suppresses the Air temperature low alarm for a
maximum of 30 minutes.
When kangaroo mode is started, some alarms are delayed for 4 minutes, as these
alarms are to be expected when the device is opened. For further information, see
the following chapter: ''Setting skin temperature alarm limits for kangaroo
mode'' (page 107)
The following table shows the duration of the suppression and the classification as
a foreseeable alarm.
