GasAlertMicro 5/PID/IR
Introduction
a Warning
To ensure personal safety, read the Safety Information -
Read First and Cautions before using the detector.
The GasAlertMicro 5, GasAlertMicro 5 PID, and GasAlertMicro 5 IR
gas detectors (“the detector”) warn of hazardous gas at levels above
user-defined alarm setpoints.
The detector is a personal safety device. It is your responsibility to
respond properly to the alarm.
Note
Unless reference is made to a specific detecto r model, the
GasAlertMicro 5, GasAlertMicro 5 PID, and GasAlertMicro 5 IR
detectors are referred to as GasAlertMicro 5/PID/IR.
Refer to Gases Monitored
prior to operating the detector.

Use the detector only as specified in this user manual, otherwise the
protection provided by the detector may be impaired.
International symbols used on the detector and in this user manual are
defined in Table 3.
Read the Cautions on the following pages before using the detector.
ec Warning
This instrument contains batteries. Do not mix with the
solid waste stream. Spent batteries must be disposed of
by a qualified recycler or hazardous materials handler.
Dispose of lithium cells immediately. Do not
disassemble and do not dispose of in fire. Do not mix
with the solid waste stream. Spent batteries must be
disposed of by a qualified recycler or hazardous
materials handler.

aCautions
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 this user manual completely before
operating or servicing.
• Do not use the detector if it is damaged. Inspect the
detector before using. Look for cracks and/or missing parts.
• If the detector is damaged or parts are missing, contact BW
Technologies by Honeywell immediately.
• Use only sensor(s) that are specifically designed for the
GasAlertMicro 5/PID/IR detectors. Refer to Replacement
Parts and Accessories.
• Calibrate the detector before first-time use and then on a
regular schedule, depending on use and sensor exposure
to poisons and contaminants. Sensors must be calibrated
regularly and at least once every 180 days (6 months).
• 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.
• BW recommends the combustible sensor be checked with a
known concentration of calibration gas after any known
exposure to catalyst contaminants/poisons (sulfur
compounds, silicon vapors, halogenated compounds, etc).
• 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.
• Warning: High off-scale LEL readings may indicate an
explosive concentration.
• Only the combustible gas detection portion of this
instrument has been assessed for performance by CSA
International.
• 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.
aCautions
• Before using common products around sensors, refer to
Sensor Poisons and Contaminants
• High concentrations of certain toxic gases, for example
H2S, may have an adverse effect on the LEL sensor. This
effect, known as inhibition, is usually temporary but in
extreme circumstances can impair the sensitivity of the LEL
sensor.
After any gas exposure that causes an alarm in the toxic
gas sensors, the LEL sensor should be verified with a bump
test, and recalibrated if necessary.
• Any rapid up-scaling reading followed by a declining or
erratic reading may indicate a gas concentration beyond
upper scale limit, which may be hazardous.

GasAlertMicro 5/PID/IR
User Manual
• Calibrate only in a safe area that is free of hazardous gas, in
an atmosphere of 20.9% oxygen.
• Use only BW approved batteries for the GasAlertMicro 5/
PID/IR detectors. Refer to Replacement Parts and
Accessories.
• Charge the detector before first-time use. BW recommends
the detector be charged after every workday.
• Charge the battery pack immediately when a low battery
alarm occurs.
• Read and adhere to the battery cautions provided in Battery
Cautions.
• Charge the GasAlertMicro 5/PID/IR batteries using the
recommended charging adapter only. Do not use any other
charging adapter. Failure to adhere to this caution can lead
to fire and/or explosion.
• Read and adhere to all instructions in the charger user
manual. Failure to do so can result in fire, electrical shock,
personal injury, and/or property damage.
• Extended exposure of the GasAlertMicro 5/PID/IR detectors
to certain concentrations of combustible gases and air may
stress a detector element, which can seriously affect its
performance. If an alarm occurs due to high concentration
of combustible gases, recalibration should be performed, or
if needed, the sensor replaced.
aCautions
• Protect the PID sensor from exposure to silicone vapors.
• When calibrating O
the Toxic 2 sensor position, a single gas calibration cap
must be used to ensure accurate calibration. For more
information, refer to Single Gas Calibration Cap
• Replace the CO
area that is free of hazardous gas.
• The optional pump (M5-PUMP) is certified for use with the
GasAlertMicro 5/PID/IR detectors only.
• Do not immerse the detector in liquids.
• Do not test the combustible sensor’s response with a
butane cigarette lighter; doing so will damage the sensor.
• Do not expose the detector to electrical shock or severe
continuous mechanical shock.
• Do not attempt to disassemble, adjust, or service the
detector unless instructions for that procedure are provided
in the user manual and/or that part is listed as a
replacement part. Use only BW Technologies by Honeywell
Replacement Parts and Accessories
• The detector warranty is void if customer, personnel, or
third parties damage the detector during repair attempts.
Repair attempts made by non-BW Technologies by
Honeywell repair/service personnel voids this warranty.
Lithium Battery Packs

Low Battery Alarm
The detector tests the batteries upon activation and continuously
thereafter. Battery power is continually displayed during normal
operation. If the battery voltage is low, the detector activates the
low battery alarm.
The low battery alarm continues until the batteries are replaced/charged,
or until the battery power is almost depleted. If the battery voltage
becomes too low, the detector deactivates.
Note
Typ ically, the low battery alarm continues for 30 minutes before
the detector automatically deactivates.
Automatic Deactivation Alarm
If the battery voltage is in immediate danger of falling below the minimum
operating voltage, the audible alarm beeps eight times and the visual
alarm flashes eight times. After 3 seconds, the LCD dims and the
detector deactivates.
To replace or charge the batteries, refer to the following sections:
• Replacing the Alkaline Batteries
• Replacing the Lithium Battery Pack
Bump Test
A bump test is the process of applying a small amount of test gas to
force the detector into alarm. A bump test should be performed regularly
to confirm the sensors are responding correctly to gas, and that the audible, visual, and vibrator alarms activate during an alarm condition. Calibrate if the readings are not within specified limits.
Performing a Bump Test
a Caution
BW recommends to bump test the sensors before each
day’s use to confirm their ability to respond to gas by
exposing the sensors to a gas concentration that
exceeds the alarm setpoints.
To perform a manual bump test refer to
page 50 and the following steps 1-6. Follow this procedure when Bump
Daily is enabled.
The Calibration icon will flash if a sensor has failed a bump
test.

Diagnostics Testing
The detector tests the ambient air (auto zero) and the test gas that is
applied (auto span) to ensure it meets expected values. Auto zero sets
the zero-gas level of the sensor. If ambient gas is present, the zero
level will be incorrect.
If excessive target gas is present, the detector displays an error
message and lists the affected sensor.
In auto span, if the target gas is not detected or does not meet expected
values, a message displays that the detector is exiting calibration mode.
The detector retains the previous set values.
