| The Slave is independently powered and has several important functions. It will:
- independently generate warnings when appropriate.
- automatically promote itself to Master, adding oxygen when necessary, if the Master fails to signal its active status.
- instantly add oxygen to the loop if the PO2 drops to 80% of setpoint.
Having invented and patented the two controller system you would expect us to favour it but when you consider it carefully– it is an essential requirement. |
