GasAlertQuattro
Introduction
Introduction
The Quick Reference Guide provides basic information to
operate the GasAlertQuattro gas detector. For complete
operating instructions, refer to the GasAlertQuattro User
Manual. The GasAlertQuattro gas detector (“the detector”) is
designed to warn of hazardous gas levels above user-defined
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 French, German, Portuguese, and
Spanish. The screens for the additional languages
are displayed on the detector and in the
corresponding Quick Reference Guide.
Zeroing the Sensors
To zero the sensors, refer to steps #1-3 in Calibration on
page 10.
Safety Information - Read First
Use the detector only as specified in this Quick Reference
Guide and the User Manual, otherwise protection provided by
the detector may be impaired. Read the following Cautions
before using the detector.
a CAUTION
•Warning: Substitution of components may impair
Intrinsic Safety.
• Before using the detector, refer to Sensor Poisons and
Contaminants on page 8.
• 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.
• 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.
• If using the detector near its upper or lower operating
temperature, BW Technologies by Honeywell
recommends zeroing or activating the detector in that
environment.
• Charge the detector before first-time use. BW
recommends the detector be charged after every
workday.
• Do not use an external power supply or charger to
operate the detector for periods greater than 24 hours. If
powering from an external source, power cycle the
detector once every 24 hours to ensure proper
operation. To power cycle the detector, press and hold
C until OFF is displayed. Release C, then press and
hold until the detector begins the start-up sequence.

GasAlertQuattro
Quick Reference Guide

• Do not use an external power source or charger to
operate the detector in a hazardous environment. The
chargers intended for use with the GasAlertQuattro
detector are not certified for use in hazardous or
potentially explosive environments.
• 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 that the sensors must be calibrated
regularly and at least once every 180 days (6 months).
• Performance standards for European certification
EN 60079-29-2 and EN 45544-4 contain guidance on
implementing a suitable calibration routine.
• Calibrate only in a safe area that is free of hazardous
gas in an atmosphere of 20.9% oxygen.
• 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.
• Only the combustible gas detection portion of this
instrument has been assessed for performance by CSA
International.
• BW recommends that the combustible sensor be
checked with a known concentration of calibration gas
after any exposure to contaminants/poisons such as
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, visual, and vibrator alarms are activated.
Calibrate if the readings are not within the specified
limits.
• For an additional bump test caution relating to the
European performance certification, refer to Bump Test.
• Caution: High off-scale LEL readings may indicate an
explosive concentration.
• Any rapid upscaling reading followed by a declining or
erratic reading may indicate a gas concentration
beyond upper scale limit, which can be hazardous.
• For use only in potentially explosive atmospheres
where oxygen concentrations do not exceed 20.9%
(v/v). Oxygen deficient atmospheres (<10% v/v) may
suppress some sensor outputs.
• Extended exposure of the GasAlertQuattro 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, a calibration
should be performed, or if needed, the sensor replaced.
• Before using common products around sensors, refer
to Sensor Poisons and Contaminants on page 8.
• 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.

GasAlertQuattro
Informations de sécurité – À lire au préalable
• Une lecture qui augmente rapidement, puis qui baisse,
ou une lecture fantaisiste peuvent être représentatives
d'une concentration de gaz excédant la limite d’échelle
supérieure et risquant donc d’être dangereuse.
• Cet appareil est destiné uniquement à une utilisation
dans des atmosphères potentiellement explosives,
dans lesquelles la concentration d’oxygène ne dépasse
pas 20,9 % (v/v). Les atmosphères pauvres en oxygène
(<10 % v/v) peuvent supprimer certaines sorties de
capteur.
• Une exposition prolongée du détecteur GasAlertQuattro
à certaines concentrations de gaz ou d'atmosphères
combustibles peut nuire à l'élément de détection et
altérer gravement ses performances. En cas d'alarme
due à une forte concentration de gaz combustible, il est
nécessaire de procéder à un réétalonnage ou de
remplacer le capteur si nécessaire.
• Avant d'utiliser des produits usuels à proximité des
capteurs, reportez-vous à Sensor Poisons and

Bump Test
A bump test applies 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.
The detector can also prompt for a bump test during startup
when the Bump Test Interval is defined. Refer to the
GasAlertQuattro User Manual.
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
alarm setpoints.
To operate the detector in accordance with performance
requirements for European certification, the user must
complete a bump test before each day’s use.
(Per EN 60079-29-1 and EN 60079-29-2.)
1. Connect the calibration hose to the 0.5 l/min regulator
on the gas cylinder. Refer to Connecting the Gas
Cylinder to the Detector on page 9.
To bump test using the MicroDock II station, refer to the

User Options and Sensor Configuration
In order to modify user options and detector configuration, the
following items are required:
• Detector
• IR Link adapter or MicroDock II
• FleetManager II software
The following section describes some of the configuration
options available in the detector. Refer to the GasAlertQuattro
User Manual and FleetManager II Quick Reference Guide for
complete information.
Device Configuration
The Device Configuration section displays data about the
detector, allows for a startup message to be entered, and
defines and enables/disables settings for the detector.
•Serial Number Field: This field displays the serial number
(e.g. QA111-001000) of the detector.
•Firmware Version: This field displays the current firmware
version that displays on the detector LCD during the
startup sequence. If new firmware is uploaded to the
detector, the Firmware Version field automatically updates.
•Hardware Version: This field displays the current
hardware version of the detector.
•Startup Message: Enter text to display on the detector
LCD during startup (50 characters maximum). Enter
information such as employee name, plant, area,
emergency number(s), etc.
•Lockout on Self-Test Error: If Lockout on Self-Test Error
is enabled and a failure occurs during the self-test, the
screen displays Sensor Self Test Error Lockout
Enabled... and the detector deactivates.
•Safe Mode: If enabled, SAFE displays continuously on the
LCD unless an alarm condition occurs.
•Confidence/Compliance Beep: If enabled, the
Confidence/Compliance Beep provides continuous audible
confirmation that the detector is operating correctly.
Frequency of the beep is defined with the Confidence/
Compliance Beep Interval option (every 1-120 seconds).
Note: Confidence/Compliance Beep automatically
disables during a low battery alarm, self-test fail,
calibration fail, bump test fail, and when an alarm
event occurs.
a CAUTION
Remove the unit from use and contact BW if the
confidence/compliance beep or IntelliFlash is not
working.
•Latching Alarms: If enabled, during an alarm condition
the Latching Alarms option causes the low and high gas
alarms (audible, visual, and vibrator) to persist until the
alarm is acknowledged and the gas concentration is below
the low alarm setpoint. The LCD displays the peak
concentration until the alarm no longer exists. Local
regulations in your region may require the Latching
Alarms option be enabled.
