- High Humidity Alarm: An audible alarm if the humidity temperature exceeds 41°C.
- Low Humidity Alarm: An audible alarm between 10 minutes @26°C.
Non-Heater Wire Circuit:
- High Airway Alarm: An audible alarm if temperature exceeds 41°C
- Low Airway Alarm: An audible alarm if temperature descends @29.5°C in invasive mode, or @26°C
non-invasive mode
- High Humidity Alarm: Light will twinkle but no alarm if the humidity temperature exceeds 66°C.
- Low Humidity Alarm: An audible alarm between 10 minutes @26°C.
