4. Confirm that you want to apply Nitrogen to zero CO
5. When Apply calibration gas now is displayed, apply the gas and wait for a maximum of five
minutes. The detector first tests for a specific type of gas. When it detects enough of that
gas for sensor calibration, a check box will be displayed next to that gas. Calibration then
begins. Gas values will adjust on the screen during the calibration.
6. When Turn gas off is displayed, disconnect the device from gas. Check marks will be
displayed next to the calibrated sensors. These sensors reset to the number of days until
the next calibration is due (for example, 180 days). The calibration cycle will take about two
minutes after which the user will be prompted to Press button to continue.
7. If the calibration was successful, Calibration Passed will be displayed. Press the button to
exit calibration. If the calibration failed for some or all of the gases, either a Cal Error All

Replace a Sensor

Use only sensors designed by Honeywell for the Honeywell BW Ultra detectors. Replace the
sensors in a non-hazardous location.
The Honeywell BW Ultra detector can be configured for a maximum of 5 gases and may contain
dummy sensors.
If an HCN is set up on the 5th, after cal/bump, the device enters to high alarm (HCN) this is
due to high cross sensitivity. The type of sensor can only be configured at factory during
assembly process.
If the user requests a BW Ultra with a dummy sensor placed in the analog sensor position, then
this sensor won't appear in the configuration options.
