• If the detector is damaged or parts are missing, contact BW Technologies by Honeywell
immediately.
• If the detector has been disassembled, ensure the front and rear shells are properly aligned and fastened before activating the detector. Refer to Maintenance
.
• Periodically test the sensor’s response to gas by exposing the detector to a targeted gas concentration that exceeds
the high alarm setpoint. Manually verify that the audible and visual alarms are activated.
• Calibrate the detector before first-time use, and then at least once every 180 days. For HCN detectors, calibrate once
every 90 days.
• Use only the Energizer 1CR2 battery. Refer to Replacing the Battery or Sensor
.
• To reduce the risk of ignition of a flammable atmosphere, batteries must only be changed in a safe area free of hazardous gas.
• Do not place the detector near the mouth or shoulders.

• Before operating an ETO detector, allow the detector to stabilize
at the temperature it will be operating in. After the detector has
stabilized, zero the detector.
• It is necessary to periodically re-zero the ETO detector.
• To ensure accurate calibration, BW recommends using a premium-grade calibration gas approved by the National Institute of
Standards and Technology (NIST).
• Do not use a gas cylinder beyond its expiration date.
• Before calibrating a new NO or ETO sensor, allow the sensor to
stabilize for 2 hours in a safe area that is free of hazardous gas.
• Calibrate a new sensor before use. Allow the sensor to stabilize
before starting calibration (used: 60 seconds; new: 5 minutes).
• Calibrate the detector at least once every 180 days (for HCN
detectors calibrate at least once every 90 days), depending upon
use and sensor exposure to poisons and contaminants.
• Calibrate the detector if the ambient gas display varies at
start-up.
• It is best to calibrate the sensor before changing the alarm setpoints.
• Calibrate only in a safe area that is free of hazardous gas.
• To disable an alarm, set the alarm setpoint to zero.
• If a certified calibration is required, contact
BW Technologies by Honeywell

Verification
1. After calibration is complete and the detector is in normal operation, verify calibration by using a gas cylinder other than the one
used for calibration.
2. The gas concentration should not exceed the sensor’s detection
range. Confirm that the LCD displays the expected concentration
values.
3. To ensure that the reading is accurate, apply the verification gas
for the same period of time as was applied to the sensor when it
was calibrated.
Example: SO
2
span time was 2 minutes therefore, apply verifica-
tion gas for 2 minutes.
