Introduction

a Warning
To ensure personal safety, read Safety Information -
Read First and a Cautions before using the detector.
The GasAlertQuattro gas detector (“the detector”) warns 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.

Safety Information - Read First

Use the detector only as specified in this technical reference guide and the operator’s manual, otherwise the protection provided by the detector may be impaired.
International symbols used on the detector and in this technic al reference guide are define d in Table 2.
Read the a Cautions on the following pages before using the detector.
ec Warning
This instrument contains a lithium polymer bat te ry. 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 hazar dous materials handler.
2
a Cautions
• Warning: Substitution of components may impair Intrinsic Safety.
GasAlertQuattro
Safety Information - Read First
• Before using the detector, refer to Sensor Poiso ns and Contaminants
• Caution: For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and understand this technical reference guide 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
• Only use sensor(s) that are specifically designed for the GasAlertQuattro. 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. BW Technologies by Honeywell recommends that the sensors 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 activate. Calibrate if the readings are not within the specified limits.
• 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.
• BW recommends the combustible sensor be checked with a known concentration of calibration gas after any known exposure to catalyst contaminants/poisons (sulfur compounds, silicone 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.
.
immediately.
3
GasAlertQuattro
Technical Reference Guide
• Only the combustible gas detection portion of this instrument has been assessed for performance by CSA International.
• For use only in potentially explosive atmospheres where oxygen concentrations do not exceed 20.9% (v/v).
• Any rapid upscaling reading followed by a declining or erratic reading may indicate a gas concentration beyond upper scale limit, which may be hazardous.
• Calibrate only in a safe area that is free of hazardous gas in an atmosphere of 20.9% oxygen.
a Cautions
• Use only BW approved batteries for the GasAlertQuattro detector. Refer to Specifications
• Charge the detector before first-time use. BW recommends the detector be charged after every workday.
• Charge the GasAlertQuattro using BW charger adapters designed for the GasAlertQuattro only. Do not use any other charging adapter. Failure to adhere to this caution can lead to fire and/or explosion.
• Extended exposure of the GasAlertQuattro 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 concentrations of combustible gases, recalibration should be performed, or if needed, the sensor replaced.
• 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.
• Deactivating the detector by removing the battery pack may cause improper operation and harm the detector.
• Do not immerse the detector in liquids.
• Do not attempt to disassemble, adjust, or service the detector unless instructions for that procedure are provided in this technical reference guide and/or that p art is listed as a replacement p art. Use only BW Technologies by Honeywell

GasAlertQuattro
Safety Information - Read First
a Cautions
• 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 battery, refer to Replacement Parts and Accessories.
• Warning: Lithium polymer cells exposed to heat at 266°F (130°C) for 10 minutes can cause fire and/or explosion.
• 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.
• Calibration cylinders that are used with a demand flow regulator must meet the following maximum inlet pressure specifications:
• Disposable cylinders 0-1000 psig/70 bar
• Refillable cylinders 0-3000 psig/270 bar
• If using the detector near it s upper o r lower oper ating te mperature, BW recommends zeroi ng or acti vating the detector in that environment.

Sensor Poisons and Contaminants

Several cleaners, solvents, and lubricants can contaminate and cause permanent damage to sensors. Before using cleaners, solvents, and lubricants in close proximity to the detector sensors, read the following caution and refer to Table 3.
a Caution
Use only the following BW Technologies by Honeywell recommended products and pr ocedures:
• Use water-based cleaners.
• Use non-alcohol based cleaners.
• Clean the exterior of the detector with a soft, damp cloth.
• Do not use soaps, polishes, or solvents.
