Alarm System
The Babytherm controller distinguishes three levels of
alarms.
High potential for patient risk
a continuous audible alarm (enunciator) that cannot be
silenced, for:
– device malfunction,
– power failure
an alarm tone sequence (loudspeaker) that can be
silenced in combination with flashing red LED, for:
– mattress heater sensor failure,
– mattress heater exceeding temperature limits,
– skin temperature sensor not connected during
skin control,
– sensor failure of tummy or toe skin temperature
sensor.
Medium potential for patient risk
an alarm tone sequence (can be silenced ) in
combination with flashing yellow LED, for:
– deviation between set and measured value for
skin or mattress temperature exceeding tolerance,
– 15-minute alarm (as a reminder to check core
temperature during manual mode with heater
levels higher than 3).
Low potential for patient risk
Display messages for:
– measured values out of measuring range,
– low battery voltage.
Any alarm that has not been acknowledged is indicated
by flashing red central alarm light on the radiant heater
unit.
The display shows a specific message for the alarm
activated.
NOTE:
A new alarm being activated will always override
audible alarm silencing.
Central Alarm
1
Red light on radiant heater starts flashing simul-
taneously with any audible alarms.
