GasAlert Extreme

Introduction

This quick reference guide provides basic information to oper­ate the GasAlert Extreme gas detector. For complete operating
instructions, refer to the GasAlert Extreme User Manual pro­vided on the CD-ROM. The GasAlert Extreme gas detector
(“the detector”) is designed to warn of hazardous gas levels
above user defined alarm setpoints.

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

Note

If you have a multi-language detector, the detector is
shipped with English as the default displayed
language. Additional languages provided are French,
German, Spanish, and Portuguese. The screens for
the additional languages are displayed on the
detector and in the corresponding quick reference
guide.

Safety Information - Read First

Use the detector only as specified in this quick reference guide
and user manual, otherwise the protection provided by the
detector may be impaired.

Read the following Cautions before using the detector.

a Cautions

• Warning: Substitution of components may impair

Intrinsic Safety.

• Warning: To prevent ignition of flammable or

combustible atmospheres, disconnect power before
servicing.

• Warning: Use only the Panasonic CR-2PE/BN. Refer to

Replacing the Battery or Sensor.

• Warning: To reduce the risk of ignition of a flammable

atmosphere, batteries must only be changed in a safe
area free of hazardous gas.

• Calibrate only in a safe area that is free of hazardous
gas in an atmosphere of 20.9% oxygen.

• Use only a sensor specifically designed for the GasAlert
Extreme model.

• Do not deactivate the detector during a work shift.

GasAlert Extreme

Quick Reference Guide

Deactivating the detector resets the time-weighted
average (TWA), short-term exposure limit (STEL), and
maximum gas exposure values to 0.

• If the detector is damaged or parts are missing, contact

BW Technologies by Honeywell

• Do not use the detector if it is damaged. Before using
the detector, inspect the case. Look for cracks and
missing parts.

• If the detector has been disassembled, ensure the front
and rear shells are properly aligned and fastened before
activating the detector. Refer to Maintenance

• BW recommends to bump test the sensor before each
day’s use to confirm its ability to respond to gas by
exposing the detector to a gas concentration that
exceeds the alarm setpoints. Manually verify that the
audible and visual alarms are activated. For detectors
with the calibration feature, calibrate the sensor if the
reading is not within the specified limits.

• Calibrate the detector before first-time use, and then at
least once every 180 days. For HCN detectors, calibrate
once every 30 days.

immediately.

• Ensure the sensor screen is not blocked.

• Do not cover the sensor grill with hands.
To avoid possible damage to the detector, adhere to the

following:

• Do not expose the detector to electrical shock and/or
severe continuous mechanical shock.

• The oxygen GasAlert Extreme detector is classified by
Underwriters Laboratories Inc. up to an atmosphere of
21% oxygen.

• Do not attempt to disassemble, adjust, or service the
detector unless instructions for that procedure are
contained in the user manual, and/or that part is listed
as a replacement part. Use only BW Technologies by
Honeywell replacement parts. Refer to Replacement
Parts and Accessories.

• The detector warranty will be voided if customer
personnel or third parties damage the detector during
repair attempts. Non-BW Technologies by Honeywell
repair/service attempts void this warranty.

• Products may contain materials that are regulated for
transportation under domestic and international
dangerous goods regulations. Return product in
compliance with appropriate dangerous goods
regulations. Contact freight carrier for further
instructions.

Replacing the Battery or Sensor

a Warning

To avoid possible personal injury, adhere to the following:

• Replace the battery in a safe area, free of hazardous gas
immediately when the detector enters low battery alarm.

• Use only the Panasonic CR-2PE/BN battery.

• Wear an ESD wrist or heel strap when replacing the
sensor or battery. Avoid touching electronic
components on the detector PCB or shorting circuits on
the PCB.

• Use only the sensor specifically designed for the
