Introduction
This quick reference guide provides basic information to oper-
ate the GasAlert Extreme gas detector. For complete operating
instructions, refer to the GasAlert Extreme User Manual pro-
vided 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.

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 immediately.
• 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.
• 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.
