NOTE: Performing a response test on the oxygen detector may cause alarms. Be sure to
put the controller into its calibration program or disable external alarms before
performing this test.
1. Place the controller into its calibration program or disable external alarms.
2. Verify that the controller display reading is 20.9% oxygen.
If the controller reading is not 20.9% oxygen, set the fresh air reading, then continue
this procedure. See “Calibration” on page 10 and the controller operator’s manual for
instructions to set the fresh air reading.
3. Exhale into the bottom of the oxygen detector housing.
4. Stop exhaling into the bottom of the detector, then verify that the reading on the
controller display decreased from the normal reading of 20.9% oxygen.
NOTE: If the reading does not decrease, calibrate the detector as described in
“Calibration” on page 10.
5. When the display reading rises above the decreasing alarm setpoint, return the
controller to normal operation.

Calibrate the detector as described in “Calibration” on page 10.
