Introduction

a Warning

To ensure your personal safety, read “Safety Information” before using the detector.

The GasAlert Extreme gas detector (“the detector”) warns of hazardous gas at levels above a factory set alarm setpoint. This product is a gas detector, not a measurement device.

The detector is a personal safety device. It is your responsibility to respond properly to the alarms.

Table 1 lists the GasAlert Extreme models and the gases monitored. This manual includes examples from each model.

• 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.
