Check Patient Alarm:
1. Manual Mode: The check patient alarm activates in the manual mode
of operation when the heater has been energized at a power level
greater than 25% for 12 minutes. The alternating single tone alarm is
activated for this condition. Pressing the alarm silence switch silences
this alarm and resets the timer for another 12 minutes of operation. If
this alarm is not silenced within 3 minutes of the check patient alarm
occurring, an alternating two tone alarm is sounded and the heater is
deactivated until the alarm silence switch is pressed.
2. Servo Mode: The check patient alarm activates in the servo mode of
operation if the heater has been at the 100% power level for 12 con-
tinuous minutes. The alternating single tone alarm is activated for this
alarm. Pressing the alarm silence switch silences this alarm and resets
the timer for another 12 minutes of operation. If this alarm is not
silenced within 3 minutes of the check patient alarm occurring, the
alternating two tone alarm is sounded and the heater is deactivated
until the alarm silence switch is pressed.
Power Failure Alarm:
A battery operated power failure alarm activates when the external power
source fails or is accidentally disconnected. The battery also provides
power to an electronic memory to recall previous control temperature
settings for approximately 10 minutes, when the battery is fully charged.
