GasAlert Extreme
Introduction
This quick reference guide provides basic information for the
GasAlert Extreme. Refer to the user manual on the
accompanying CD-ROM for complete operating instructions.
The GasAlert Extreme gas detector (“the detector”) warns of
hazardous gas at levels above user-selectable 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, English is set as
its default. The Portuguese, Spanish, German, and
French guides have their screenshots displayed in the
corresponding language.
Safety Information - Read First
Use the detector only as specified in this manual, otherwise
the protection provided by the detector may be impaired.
Read the following Cautions before using the detector.
aCautions
⇒ Warning: Substitution of components may
impair Intrinsic Safety.
⇒ Warning: To prevent ignition of flammable
or combustible atmospheres, disconnect
power before servicing.
⇒ The GasAlert Extreme oxygen detector is
classified by Underwriters Laboratories Inc.
up to an atmosphere of 21% oxygen.

Calibration
Procedure Display Procedure Display
1. In a clean atmosphere, press E
and C simultaneously and hold for
5 seconds. The detector beeps
four times. The detector then
beeps once more signifying that
calibration has started.
5. When the display flashes the gas
cylinder, connect the calibration
bottle and apply gas at a flow rate
of 500 to 1000 ml/min. (refer to the
next page). The detector beeps
three times at the end of the span
stage. Remove the calibration gas.
2. The display flashes AUTO-ZERO
while the detector automatically
zeroes the sensor. The detector
beeps twice at the end of the auto-
zero stage.
6. Press Eor Dto change the next
calibration due date. Press Cto
save.
3. If the detector is pass code
protected, PASS flashes on the
display. The correct pass code
must be entered before proceeding
to set span.
7. Press Cto save the current alarm
setpoint. Press Eor Dto change
the alarm setpoint and press Cto
save the new value. The detector
beeps and vibrates four times at
the end of calibration.
4. The display flashes the current
calibration gas setting. You can
press Cto accept the current
setting, or you can press Eor D
to change the setting and press C
to confirm your new selection.
aWarning
For correct flow and span rates, refer to your user
manual.

Note
During an alarm condition, the detector activates the backlight and the display shows the current ambient gas reading.
The high alarm and STEL alarm have the same priority. A high alarm and/or STEL alarm override a low alarm and/or TWA
alarm.
The vibrator alarm is disabled at -20°C.

Maintenance
To keep the detector in good operating condition, perform
the following basic maintenance as required:
• Calibrate, test, and inspect the detector at regular
intervals.
• Keep an operations log of all maintenance,
calibrations, and alarm events.
• Clean the exterior with a soft damp cloth. Do not use
solvents, soaps, or polishes.
• Do not immerse the detector in liquids.
Replacing the Battery or Sensor
a Warning
To avoid possible injury:
Replace the battery as soon as the detector emits a
low battery alarm.
Use only the Energizer 1CR2 battery.
Use only the sensor specifically designed for your
GasAlert Extreme model. Otherwise, the detector
will not monitor the target gas.
Note
When you remove the battery from the detector, the
clock will revert back to its default value.
To preserve the life of the battery, turn it off when you are not
using it.
The following figure and table illustrate how to replace the
battery or sensor. The detector must be turned off before you
replace the battery or sensor. Use a Phillips head screwdriver
to loosen and tighten any screws.
Do not use excessive force when removing or inserting the
sensor or the sensor can be damaged. Gently rocking the
sensor back and forth can help free a tightly held sensor.
When placing the sensor screen back, ensure that the shiny
side is facing away from the sensor.
After replacing a sensor or battery, ensure that the detector’s
back screws are torque to 3-4 in-lbs in a crisscross pattern to
ensure a proper environment seal.

This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules and ICES-003 Canadian EMI requirements. These
limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
