Operator’s Manual

GasAlertQuattro

Introduction

The operator’s manual provides basic information to operate
the GasAlertQuattro gas detector. For complete operating
instructions, refer to the GasAlertQuattro Technical Reference
Guide provided on the CD-ROM. 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.

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 operator s

manual.

Note

Zeroing the Sensors

To zero the sensors, refer to steps #1-3 in Calibration on
page 8.

Safety Information - Read First

Use the detector only as specified in this operator’s manual and
the technical reference guide, otherwise protection provided by
the detector may be impaired. Read the following Cautions
before using the detector.

a

Cautions

• Warning: Substitution of components may impair Intrinsic

Safety.

• Before using the detector, refer to Sensor Poisons
and Contaminants.

• 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 technical reference guide completely
before operating or servicing.

• Charge the detector before first-time use. BW Technologies
by Honeywell recommends the detector be charged after
every workday.

• 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).

• 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.

• Caution High off-scale LEL readings may indicate an
explosive concentration.

2

• 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.

• For use only in potentially explosive atmospheres where
oxygen concentrations do not exceed 20.9% (v/v).

• 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.

• Warning: The lithium battery (QT-BAT-R01) may present
a risk of fire or chemical burn hazard if misused. Do not
disassemble, heat above 212°F (100°C), or incinerate.

• Warning: Do not use any other lithium batteries with the
GasAlertQuattro detector. Use of any other cell can cause
fire and/or explosion. To order and replace the QT-BAT-R01
lithium battery, contact BW Technologies by Honeywell.

• Warning: Lithium polymer cells exposed to heat at 266°F
(130°C) for 10 minutes can cause fire and/or explosion.

• ec Warnin g: This instrument contains a lithium polymer
battery. Dispose of used 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.

• Keep lithium cells away from children.

• Deactivating the detector by removing the battery pack
may cause improper operation and harm the detector.
