- Check that the oxygen levels are normal (around 20% and at least 18%). If they are consistently low, leave the area and call EH&S. If they are nonsensical or fluctuating randomly, the cartridge probably requires replacing or the sensor re-calibration. In this case, it might not be possible to completely silence the alarm without calling a technician, but you can try!
- Assuming the oxygen levels are normal, check the alarm thresholds. Go into the main menu by hitting "esc," then choose "Configuration Menu," then "Configure Alarms." You may have to enter a password, which should be written on the face of the device. Make sure that Alarm 1 and Alarm 2 are set below the current O2 level (For safety, Alarm 1 should not be lower than about 17.5%). Check that "Overrange Latching" is set to "No."
- Now make sure that the alarm is in a normally disabled, non-latching state. Back in the Configuration Menu, choose "Configure Relays." Set Alarm 1 and Alarm 2 to "ND NonLatching," and then hit "esc" until you get back to measurement mode. If all has gone well, the alarm should stop.
- If all else fails, you can always cover the noisemaker with tape and foam.
- Contact the facilities manager and ask him to call Apollo to perform maintenance on the sensor. Do this regardless of whether you have successfully silenced the alarm.
