Instruction Sheet
Introduction
The GasAlertClip Extreme gas detector (“the detector”) is a personal safety
device that warns when hazardous gas exceeds factory set alarm setpoints.
The detector stores and transmits gas alarm event data. It is your
responsibility to respond properly to the alarm.

a Safety Information - Read First
Warning: Substitution of components may impair intrinsic safety.
Warning: To prevent ignition of flammable or combustible
atmospheres, disconnect power before servicing.
⇒ Do not activate the detector after the date on the package.
⇒ This product is a gas detector, not a measurement device.
⇒ Perform a self-test each day prior to use.
⇒ Make sure the sensor grill is free of dirt and debris.
⇒ Make sure the sensor grill is not covered.
⇒ Periodically test the sensor’s response to gas by exposing the
detector to a target gas concentration that exceeds the low alarm
setpoint. Manually verify that the audible and visual alarms are
activated.
⇒ Periodically calibrate the GasAlertClip Extreme O2.
cNote:
This instrument contains a lithium battery. Do not mix with the solid
waste stream. Spent batteries should be disposed of by a qualified
recycler or hazardous materials handler.

Activating the Detector
Press and hold C for 5 seconds.
Note: Once activated, the detector cannot be turned off.
Note: The detector will not respond to gas for approximately 30 seconds
after the self-test.
The detector performs the actions in steps 1-5. Manually check that all the
actions occur.
1. The detector emits one beep, one flash, and one vibration.
2. The detector sets the life-remaining clock.
3. All LCD elements are displayed.
4. Test flashes while the sensor integrity and battery life are tested.
5. The low and high alarm setpoints are displayed.
Self-Test Pass
• The detector emits a short beep and a single vibration.
• uis displayed.
• Twenty hours after running the self-test, Test is displayed.
Self-Test Fail
• The detector emits five short beeps.
• Test continues to be displayed.
Repeat the self-test. If the self-test fails three consecutive times, the display
goes blank and the detector goes into safety shutdown mode.
Automatic Battery Test
The battery is automatically tested every 2 hours. If the battery test fails,
another automatic test is initiated 30 minutes later. After three consecutive
battery test failures, the display goes blank and the detector enters safety
shutdown mode.
Life-Remaining Clock
The life-remaining clock indicates how much longer the detector will
operate. The display shows the countdown of remaining months, then days,
and then hours. The detector continues to operate for a maximum of 8
hours after the life-ended alarm (refer to the Alarms section). Press Cto
turn off the detector.
Safety Shutdown Mode
The display goes blank in safety shutdown mode. The detector then beeps,
flashes and vibrates quickly (twice per second) until the battery loses power.
To turn off the detector before the battery loses power, press C. Contact
your BW Technologies distributor.
The detector goes into safety shutdown mode if:
• The self-test fails three consecutive times.
• The automatic battery test fails three consecutive times.
• You do not turn off the detector manually within 8 hours of the life-ended
alarm.
Gas Alarm Setpoints
The following is a list of the factory alarm setpoints.
Model Low Alarm
Setpoint High Alarm Setpoint
GasAlertClip Extreme O219.5% 23.5%
GasAlertClip Extreme CO 35 ppm 200 ppm
GasAlertClip Extreme H2S 10 ppm 15 ppm
GasAlertClip Extreme SO25 ppm 10 ppm
Note: May be equipped with customer specified alarm setpoints.
Displaying the Gas Alarm Setpoints
Press Cto display the alarm setpoints.

Note: When the gas levels return to the acceptable range, the gas alarm
stops.
Note: The life of the battery decreases rapidly under alarm conditions.
Note: The life-ended alarm occurs when the life-remaining clock displays 0
hours.
Maximum Gas Exposure
The detector records the maximum gas exposure under alarm conditions
and begins calculating the number of hours since the maximum exposure
occurred.
For each new exposure greater than the current maximum exposure, the
detector resets the maximum gas exposure to the new level and resets
hours to 0. After 24 hours of gas readings in the acceptable range, the
detector resets both values to 0.
Viewing the Maximum Gas Exposure
Press Cwithin 24 hours of receiving a gas alarm.
The detector displays the following:
1. The low and high alarm setpoints.
2. The maximum gas exposure and the hours since the exposure.
For exposures beyond the detection range, the display shows OL.
Performing a Self-Test
When it is time to perform the self-test, the display shows Test.
The self-test is activated prior to any feature when Cis pressed and Test is
displayed. The self-test must be performed in an atmosphere that is free of
background gas.
Note: The detector will not respond to gas for approximately 30 seconds
after the self-test is complete.
To perform a self-test, press and hold C for approximately 1 second.
1. The detector emits one beep, one flash, and one vibration.
2. All LCD elements are displayed.
3. Test flashes while the sensor integrity and battery life are tested.
4. The low and high alarm setpoints are displayed.
5. If an alarm occurred in the last 24 hours, the maximum gas exposure
and hours since the exposure are displayed.
6. Prn and then flashes.
Note: If you press
Cwhen the uis displayed, steps 1-3 are skipped.
To determine whether the self-test has passed or failed, refer to the Self-
Test Pass and Self-Test Fail section.

Calibrating the Oxygen Detector
The GasAlertClip Extreme O2self-calibrates using ambient oxygen levels.
Calibrate the detector only in a normal atmosphere (approximately 20.9%
O2).
To calibrate the GasAlertClip Extreme O2:
1. Press and hold Cfor approximately 3 seconds.
2. The detector emits one beep, one flash, and displays the following:
One vibration and a prolonged beep signifies a successful calibration. If
after a second calibration attempt the beep does not sound, contact your
BW Technologies distributor.
Gas Event Data Transmission
The detector stores the last 10 alarm events. The recorded data includes
the serial number, life remaining, self-tests performed, total number of
events and the duration of all events encountered, gas type and the alarm
level (in ppm or %), time elapsed since the alarm occurred (in days, hours,
and minutes), and the duration of the alarm (in minutes and seconds).
To transmit the data to a device:
1. With the receiving device on, position the detector and the device as
shown in the following illustration.
2. Press C on the detector.
3. Prn and will then flash. Within 5 seconds press Cto begin
transmission.
4. While the data is being transmitted, Ywill come on and will flash. A
countdown timer will display, as a percentage, how much data is left to
be transmitted.
