The detector, IR Link adapter, and Fleet Manager II software are required to define options. Refer to the GasAlertMax XT II Technical Reference Guide and Fleet Manager II Operator’s Manual. For user and sensor options, refer to the following:

Device Configuration

  • Startup Message Top Line: Enter a line of text to display on the LCD during startup (maximum 25 characters).
  • Startup Message Bottom Line: Enter a line of text to display on the LCD during startup (maximum 25 characters).
  • Lockout on Self-Test Error (sensor alarm lock): If a sensor fails during startup and the Lockout on Self-Test option is enabled, Safety Lock On displays on the LCD and the detector deactivates.
  • Safe Mode: If enabled, SAFE displays continuously on the LCD unless an alarm condition occurs.
  • Confidence Beep: If enabled, the confidence beep provides continuous confirmation that the detector is operating correctly. To define how often the detector beeps (every 1-120 seconds), enter the value in the Confidence Interval field. Confidence beep is automatically disabled during a low battery alarm.
  • Latching Alarms: Enable to ensure an alarm persists until the alarm is acknowledged and the gas concentrations are below the alarm setpoint. The audible alarm can be temporarily deactivated for 30 seconds by pressing Gas alarm, but the LCD continues to display the high peak concentration until the alarm condition no longer exists.
  • Force Calibration: If enabled, the detector must be calibrated if a sensor is overdue upon startup. User defined (0- 365 days) in the Calibration Interval field.
  • Cal IR Lock (must use IR device to calibrate): If enabled, the detector automatically auto zeros, but the sensors must be spanned using the IR Link or MicroDock II station with Fleet Manager II.
  • Force Bump: If enabled, a bump test must be performed to ensure the sensor(s) are responding correctly to the test gas. User defined (0-365 days) in the Bump Interval field.
  • Location Logging: If enabled, a series of numbers (1-999) can be entered on the detector to identify gas wells, plants, and other areas that identify the location where the detector is being used.
  • Force Block Test: If enabled, a pump block test must be performed during the startup tests.
  • Datalog Interval (seconds): Define how often the detector records a sample (every 1-120 seconds).
  • Confidence Interval (seconds): Define how often the detector beeps (1-120 seconds) when the Confidence Beep option is enabled.
  • Language: The LCD displays the screens in English, Français (French), Deutsch (German), Español (Spanish), or Português (Portuguese). Select the language from the drop-down menu in Fleet Manager II.

Sensor Configuration (H2S, CO, LEL, and O2)

  • Sensor Disabled: Enables/disables the selected sensor.
  • Calibration Gas (ppm): Define the span gas concentration for each sensor. The span gas concentration must match the span value on the gas cylinder.
  • Calibration Interval (days): Define the number of days (0- 365) when the next calibration is due.
  • Bump Interval (days): Define the number of days (0-365) when the next bump test is due.
  • Low Alarm (ppm): Define the low alarm setpoint for each sensor.
  • High Alarm (ppm): Define the high alarm setpoint for each sensor
  • TWA Alarm (ppm): Define the time-weighted average (TWA) alarm setpoint (toxic sensors only).
  • STEL Alarm (ppm): Define the short-term exposure limit (STEL) alarm setpoint (toxic sensors only).
  • STEL Interval (minutes): Define the short-term exposure limit (STEL) from 5-15 minutes (toxic sensors only).
  • TWA Period (hours) (TWA moving average (hours): The TWA Period option is used to define a time-weighted moving average of accumulated gases over a period of 4-16 hours, to ensure the worker leaves the area when the defined maximum average is accumulated.
  • Correction Factor (%): Enter the compensation factors for hydrocarbons other than methane. The factor can only be applied if the LEL sensor has been calibrated with methane (LEL only).
  • 50% LEL = (%CH4): Enter a percentage value to display the LEL reading as %vol., assuming a methane environment (LEL only).
  • Auto-Zero on Startup: Enable/disable the detector to automatically zero the sensor(s) during startup (H2S, CO, LEL, and O2).
  • LEL by Volume CH4: If enabled, the detector operates assuming a methane (CH4) calibration. Enable to read and display %CH4 values. Disable to read and display %LEL values.
  • 5% LEL Over-span: If enabled, the detector automatically over-spans the LEL sensor by 5% LEL above the span gas concentrations to ensure the detector is in compliance with CAN/CSA C22.2 No. 152.
  • 20.8% Base Reading: When enabled, the detector is configured to detect 20.8% O2 as ambient air. When disabled, the detector is configured to detect 20.9% O2 as ambient air.
  • Low Alarm Acknowledge: If enabled, the audible alarm can be temporarily disabled during a low alarm by pressing Gas alarm. The vibrator, alarm LEDs, and LCD remain operational (toxic and LEL only).
