Operator's Manual

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.
• 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 technical reference guide
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
• Charge the detector before first-time use. BW
recommends the detector be charged after every
Shop for Gas products online at:
• 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
until OFF is displayed. Release
hold until the detector begins the start-up sequence.
• 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
, then press and
