The obligations set forth in this warranty are conditional on:
a) property storage, installation, calibration, use, maintenance and compliance with the product manual instructions and any other applicable recommendations of BW;
b) the buyer promptly notifying BW of any defect and, if required, promptly making the product available for correction. No goods shall be returned to BW until receipt by the buyer of
shipping instructions from BW; and
c) the right of BW to require that the buyer provide proof of purchase such as the original invoice, bill of sale or packing slip to establish that the product is within the warranty period.

GasAlert Extreme
Introduction
aWarning
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.

Safety Information - Read First
Use the detector only as specified in this manual, otherwise the protec-
tion provided by the detector may be impaired.
International symbols used on the detector and in this manual are
explained in Table 2.
Read the Warnings and Cautions on the following pages before using
the detector.
cNote
This instrument contains a lithium battery. Do not mix with
the solid waste stream. Spent batteries should be dis-
posed of by a qualified recycler or hazardous materials
handler.

User Manual
aCaution
To avoid possible personal injury, adhere to the following:
• Warning: Substitution of components may impair Intrinsic Safety.
• Warning: To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.
• Do not use the detector if it is damaged. Before using the detector, inspect the case. Look for cracks and missing
parts.
• Use only a sensor specifically designed for the GasAlert Extreme model. Refer to Replacement Parts and Accesso-
ries.
• Do not deactivate the detector during a work shift. Deactivating the detector resets the time-weighted average (TWA),
short-term exposure limit (STEL), and maximum gas exposure values to 0. Refer to Alarms.
• Ensure the sensor screen is not blocked.
• If the detector is damaged or parts are missing, contact BW Technologies by Honeywell immediately.
• If the detector has been disassembled, ensure the front and rear shells are properly aligned and fastened before acti-
vating the detector. Refer to Maintenance.
• Periodically test the sensor’s response to gas by exposing the detector to a targeted gas concentration that exceeds
the high alarm setpoint. Manually verify that the audible and visual alarms are activated.
• Calibrate the detector before first-time use, and then at least once every 180 days. For HCN detectors, calibrate once
every 90 days.
• Use only the Energizer 1CR2 battery. Refer to Replacing the Battery or Sensor.
• To reduce the risk of ignition of a flammable atmosphere, batteries must only be changed in a safe area free of hazard-
ous gas.
• Do not place the detector near the mouth or shoulders.

aCaution
Table 2. International Symbols
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 replace-
ment 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.
