period of two years, beginning on the date of shipment to the buyer. This warranty extends only to the sale of new and unused products to
the original buyer. BW’s warranty obligation is limited, at BW’s option, to refund of the purchase price, repair, or replacement of a defective
product that is returned to a BW authorized service center within the warranty period. In no event shall BW’s liability hereunder exceed the
purchase price actually paid by the buyer for the Product. This warranty does not include:
a) fuses, disposable batteries or the routine replacement of parts due to the normal wear and tear of the product arising from
use;
b) any product which in BW’s opinion, has been misused, altered, neglected or damaged by accident or abnormal conditions of
operation, handling or use;
c) any damage or defects attributable to repair of the product by any person other than an authorized dealer, or the installation
of unapproved parts on the product; or
The obligations set forth in this warranty are conditional on:
a) proper 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

GasAlertMicro 5 IR
Introduction
The quick reference guide provides basic information to
operate the GasAlertMicro 5 IR gas detector. For complete
operating instructions, refer to the GasAlertMicro 5/PID/IR User
Manual provided on CD-ROM. The GasAlertMicro 5 IR detector
(“the detector”) is designed to warn of hazardous gas levels
above user-selectable alarm setpoints.
The detector is a personal safety device. It is your responsibility
to respond properly to the alarm.
Note
The detector is shipped with English as the default
displayed language. Additional languages provided are
Portuguese, Spanish, German, and French. The screens
for the additional languages are displayed on the
detector and in the corresponding Quick Reference
Guides.
Safety Information - Read First
Use the detector only as specified in this guide and the user
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.
⇒Caution: For safety reasons, this equipment must
be operated and serviced by qualified personnel
only. Read and understand the user manual
completely before operating or servicing.
⇒Calibrate the detector before first-time use and
then on a regular schedule, depending on use and
sensor exposure to poisons and contaminants.
BW recommends at least once every 180 days (6
months).

GasAlertMicro 5 IR
Quick Reference Guide
2
⇒It is recommended that the combustible sensor be
checked with a known concentration of calibration
gas after any known exposure to contaminants or
poisons (sulfur compounds, silicon vapors,
halogenated compounds, etc.).
⇒BW recommends to “bump test” the sensors
before each day’s use to confirm their 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. Calibrate if the readings are not
within the specified limits.
⇒Only the combustible gas detection portion of this
instrument has been assessed for performance by
CSA International.
⇒The combustible sensor is factory calibrated to
50% LEL methane. If monitoring a different
combustible gas in the % LEL range, calibrate the
sensor using the appropriate gas.
⇒Caution: High off-scale readings may indicate an
explosive concentration.
⇒Protect the combustible sensor from exposure to
lead compounds, silicones, and chlorinated
hydrocarbons. Although certain organic vapors
(such as leaded gasoline and halogenated
hydrocarbons) may temporarily inhibit sensor
performance, in most cases the sensor will
recover after calibration.
⇒For use only in potentially explosive atmospheres
where oxygen concentrations do not exceed
20.9% (v/v).
⇒Any rapid up-scaling reading followed by a
declining or erratic reading may indicate a gas
concentration beyond upper scale limit, which can
be hazardous.
⇒Extended exposure of the GasAlertMicro 5 IR to
certain concentrations of combustible gases and
air may stress the detector element that can
seriously affect its performance. If an alarm
occurs due to a high concentration of combustible
gases, recalibration should be performed, or if
needed, the sensor replaced.
⇒The BW pump module (M5-PUMP) is certified for
use with the GasAlertMicro 5, GasAlertMicro 5
PID, and GasAlertMicro 5 IR models only.
⇒When calibrating O3and ClO2sensors that are
located in the Toxic 2 position of the detector, a
single gas calibration cap must be used to ensure
accurate calibration.
⇒Use only the GasAlertMicro 5 IR battery pack with
the GasAlertMicro 5 IR detector. The IR battery pack
is not compatible with other GasAlertMicro 5/PID
products and vice versa.
⇒Replace the CO2sensor only in a safe area that is
free of hazardous gas.

Calibration
Procedure Display Procedure Display
Calibrate only in a safe area that is free of
hazardous gas.
1. Activate the detector. To enter
calibration, press and hold Cand H
simultaneously. The detector beeps
and flashes to the corresponding
countdown. The detector then displays
Starting calibration.
4. The following three screens display:
- Apply span gas now to calibrate
- or press Cto select sensor(s)
- or press Ato skip calibration
If none of the buttons are pressed,
proceed to step #6. If Cis pressed,
proceed to step #5. If Ais pressed,
proceed to the end of step #7.
2. flashes while the detector
zeroes all of the sensors (except CO2)
and calibrates the oxygen sensor. If a
sensor fails to auto zero, it will bypass
the span.
5. Select which sensor to span. Press G
and Hto scroll to the required sensor
and then press Cto select. Sensors
must be spanned in the following order:
Exotics (NH3, ClO2, O3, Cl2, and CO2),
Single gas, Quad gas (H2S, CO, O2, and
LEL).
3. The Zero CO2?screen displays. Press
C to zero the CO2sensor or press A
to bypass.
If Cis pressed to zero the CO2
sensor, the following screens display:
- Apply CO2zero gas now (nitrogen
must be used to zero the CO2sensor).
- The Auto-Zero CO2screen displays
and flashes.
6. Attach the calibration cap and apply gas
at a flow rate of 500 ml/min.

•Calibrate, bump test, and inspect the detector on a
regular schedule.
•Maintain an operations log of all maintenance, bump
tests, 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.

Maintenance
Replacing the Batteries
aWarning: Use only the GasAlertMicro 5 IR battery pack with the GasAlertMicro 5 IR detector (not compatible with
other Micro 5/PID models and vice versa). Refer to the warning label located on the battery pack lid.
aWarning: Always deactivate the detector before removing the battery pack.
The battery packs are user-changeable in hazardous areas, but the alkaline batteries inside the pack must be changed
in a safe area that is free of hazardous gas.
1. Open the latch on the bottom of the detector and remove the battery pack by lifting the bottom end of the pack upwards.
2. Unscrew the two captive screws on the battery pack cover, open the pack, and replace the three alkaline batteries.
3. Replace the battery pack cover and reinsert the screws.
4. Replace the battery pack on the detector and secure the latch.
