 If low oxygen is detected, an alarm will sound, and the area should be evacuated, and accelerator staff contacted.

 == Sensor Info ==
-The monitors are equipped with remote probes, to allow placement closer to the floor, since the risk is primarily from heavier than air gasses.  The Ziurconium Oxide sensors used in these devices are expected to have a 10 year service life.  FIXME: We should find out how to tell when the sensors might be failing.  Also need to understand if the remote probe contains the sensor, and will that allow field replacement?
+The monitors are equipped with remote probes, to allow placement closer to the floor, since the risk is primarily from heavier than air gasses.  The Ziurconium Oxide sensors used in these devices are expected to have a 10 year service life.  The sensor is located in the remote probe, and could theoretically be sent back for repair separately from the head unit.  AMI recommends returning both the head unit and sensor together.  Sensors are approaching end of life when their span factor is approaching 1000.  The span factor can be checked through the command center software, or by pressing the "up" button on the front panel.
+= Calibration Info =
+The sensors should be calibrated quarterly.  We should add this to our quarterly radiation safety checks.
