GasAlert Extreme User Manual Viewing Gas Exposures Computed Gas Exposures aWarning To avoid possible personal injury, do not deactivate the detector during a work shift. The detector automatically resets the TWA, STEL, and MAX gas exposures at start-up. If the detector is restarted during a work shift, the values will not reflect the entire work shift. Table 7. Computed Gas Exposures Gas Exposure TWA • • • MAX* • Time-weighted average based on an 8-hour workday. Accumulated value.
GasAlert Extreme Alarms Oxygen For oxygen detectors, press C and D simultaneously to view both the maximum low and maximum high levels of oxygen exposure. Gas Alarm Setpoints Table 8. Gas Alarm Setpoints Alarm Condition TWA alarm TWA above TWA alarm setpoint. (O2: not applicable) STEL alarm STEL above STEL alarm setpoint. (O2: not applicable) Low alarm Toxic gases: Ambient gas level above low alarm setpoint. The detector gas alarm setpoints trigger the gas alarms that are described in Table 8.

GasAlert Extreme Alarms Stopping a Gas Alarm Sensor Alarm The low and high alarms stop when the ambient gas level returns to the acceptable range. The detector tests for a missing or defective sensor during the activation self-test. Refer to Troubleshooting. The detector computes the TWA and STEL value. If the value is above the alarm setpoint, the detector activates the TWA and/or the STEL alarm. To stop the TWA and/or STEL alarm, press and hold C for 6 seconds, or deactivate the detector.
GasAlert Extreme User Manual Automatic Shutdown Alarm Calibration and Setting Alarm Setpoints There are two situations when an automatic shutdown alarm occurs: Guidelines 1. If the battery voltage is in immediate danger of dropping below the minimum operating voltage, the audible alarm beeps eight times, the visual alarm flashes eight times, and the detector emits eight vibrations. After 3 seconds, the LCD powers off and the detector stops normal operation.
GasAlert Extreme Calibration and Setting Alarm Setpoints • It is necessary to periodically re-zero the ETO detector. • Calibration accuracy is never better than the calibration gas accuracy. BW Technologies recommends a premium grade calibration gas. Gases with the National Institute of Standards and Technology (NIST) traceable accuracy will improve the validity of the calibration. Do not use a gas cylinder beyond its expiration date. • Calibrate a new sensor before use.
GasAlert Extreme User Manual Test Cap The calibration cap and hose that are shipped with the detector simplifies the sensor testing and calibration. Refer to Table 10 and Figure 3 for installation information. Note Only use the calibration cap during the calibration process. Table 10. Test Cap Item Description 1 Test cap 2 Hose 3 Regulator and gas cylinder Figure 3.
GasAlert Extreme Calibration and Setting Alarm Setpoints Calibration Procedure The calibration (CAL.) process requires several functions, some of which can be bypassed. A note is added to each option that can be bypassed. Start Calibration After the CAL. Screen displays, the detector beeps once and the auto zero screen displays. Auto Zero The auto zero function automatically zeros the toxic sensors and calibrates the O2 sensor.
GasAlert Extreme User Manual Auto Zero Fail Pass Code Protected If the sensor fails auto zero, an error message displays. After a successful auto zero, and if the pass code protected option is enabled, the PASS code protection screen displays. When enabled, the pass code is required to access the auto span and alarm setpoint functions. The detector then bypasses the sensor span and automatically proceeds to the alarm setpoints.
GasAlert Extreme Calibration and Setting Alarm Setpoints If the pass code is selected incorrectly or if the pass code is correct but not confirmed within 10 seconds, the LCD displays the following error message. 4. Press D or E to select the required gas concentration. The detector value must match the concentration value of the calibration gas. Note The detector then beeps four times and automatically returns to normal operation.
GasAlert Extreme User Manual Note Verify that the calibration gas being used matches the span concentration values that are defined for the detector. For more information, refer to Span Concentration. The set span screen displays a flashing gas cylinder. Note The flashing gas cylinder icon does not display for oxygen (O2) detectors. 6. Apply the calibration gas. 7. Apply gas to the sensor at a flow rate of 500 ml/min. (for NH3, Cl2, and ETO: 1000 ml/min.
GasAlert Extreme Calibration and Setting Alarm Setpoints If the span fails confirm that • gas is being applied to the sensor, • the sensor is detecting a sufficient gas concentration within 30 seconds, and • the gas concentration has not dropped significantly during the 2-minute span. If the span is still unsuccessful, attach a new gas cylinder. If the span continues to be unsuccessful, replace the sensor. Refer to Replacing the Battery or Sensor.
GasAlert Extreme User Manual When the CAL DUE function has been completed, the Set TWA alarm setpoint screen automatically displays. 10. Press D or E to scroll to the required value. 12. Press D or E to scroll to the required value. 11. Press C to save the new value and proceed to the STEL alarm setpoint. 13. Press C to save the new value and proceed to the low alarm setpoint.
GasAlert Extreme Calibration and Setting Alarm Setpoints 16. Press D or E to scroll to the required value. 17. Press C to save the new value and return to normal operating mode. 14. Press D or E to scroll to the required value. 15. Press C to save the new value and proceed to the high alarm setpoint. Note If the new value is not confirmed within 10 seconds after selecting, the detector automatically retains the existing value.
GasAlert Extreme User Manual Maintenance Cleaning a Sensor To maintain the detector in good operating condition, perform the following basic maintenance as required: Remove the sensor. Clean using a soft, clean brush. Do not use water. • Calibrate, bump test, and inspect the detector on a regular schedule. • Maintain an operations log of all maintenance, calibrations, and alarm events. • Clean the exterior with a soft damp cloth. Do not use solvents, soaps, or polishes.
GasAlert Extreme Replacing the Battery or Sensor Replacing the Battery or Sensor a Warning Figure 4 and Table 11 illustrate how to replace the battery or sensor. If the detector is activated, deactivate it before replacing the battery or sensor. Use a Phillips screwdriver to loosen and tighten any screws. To avoid possible personal injury: Replace the battery as soon as the detector emits a low battery alarm. Use only the Energizer 1CR2 battery.

GasAlert Extreme Troubleshooting If you still are unable to correct the problem, contact BW Technologies. Troubleshooting The electronics of the detector are protected from variations in humidity and corrosive atmospheres. If a problem is encountered, try the solutions listed in the following table. Table 12. Troubleshooting Tips Problem The detector does not activate. The detector enters alarm mode immediately when it is activated.
GasAlert Extreme User Manual Table 12. Troubleshooting Tips (cont.) Problem Possible Cause Solution The activation self-test fails during one of the checks. → General fault → Contact BW → Alarm setpoints are incorrect → Reset alarm setpoints The detector does not display normal ambient gas reading after activation self-test.
GasAlert Extreme Troubleshooting Table 12. Troubleshooting Tips (cont.) Problem Possible Cause Solution → Alarm setpoint(s) are set incorrectly → Reset alarm setpoints → Alarm setpoint(s) set to zero → Reset alarm setpoints → Detector is in calibration mode → Complete the calibration procedure → Ambient gas levels are near alarm setpoint or the sensor is exposed to a puff of the targeted gas → Detector is operating normally. Use caution in suspect areas. Check MAX gas exposure reading.
