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.

GasAlertQuattro

Introduction

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.

Page 6

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 H

S, 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.

Page 7

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.

• 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.

•

e Warning: 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.

• Products may contain materials that are regulated for transportation under domestic and international dangerous goods regulations. Return product in compliance with appropriate dangerous goods regulations. Contact freight carrier for further instructions.

Page 8

GasAlertQuattro

Quick Reference Guide

Technologies by Honeywell recommande de mettre le détecteur à zéro ou de l'activer dans cet environnement.

• Chargez le détecteur avant sa première utilisation. BW recommande de recharger le détecteur après chaque journée d'utilisation.

• N'utilisez pas une alimentation externe ou un chargeur pour faire fonctionner le détecteur sur des périodes supérieures à 24 heures. En cas d'alimentation par une source externe, redémarrez le détecteur toutes les 24 heures pour garantir son fonctionnement correct. Pour redémarrer le détecteur, maintenez la touche C enfoncée jusqu'à ce que OFF s'affiche. Relâchez la touche C, puis maintenez-la enfoncée jusqu'à ce que le détecteur lance la séquence de démarrage.

• N'utilisez pas d'alimentation externe ou de chargeur pour faire fonctionner le détecteur dans un environnement dangereux. Les chargeurs conçus pour le détecteur GasAlertQuattro ne sont pas certifiés pour une utilisation dans des environnements dangereux ou potentiellement explosifs.

• Étalonnez le détecteur avant sa première utilisation, puis de manière régulière, en fonction de l’utilisation et de l’exposition du capteur aux poisons et autres contaminants. BW recommande d'étalonner les capteurs régulièrement et au moins une fois tous les 180 jours (6 mois).

• Les normes de performance pour la certification européenne EN 60079-29-2 et EN 45544-4 contiennent des conseils sur la mise en œuvre d'une routine d'étalonnage appropriée.

• Veillez à effectuer l'étalonnage dans une zone sûre, exempte de gaz dangereux, dans une atmosphère contenant 20,9 % d'oxygène.

• Le capteur de gaz combustible est étalonné en usine au méthane à une concentration de 50 % LIE. Si la surveillance porte sur un autre gaz combusstible dans la plage de % LIE, étalonnez le capteur en utilisant le gaz approprié.

• Seul l'élément de détection de gaz combustibles de cet appareil a fait l’objet d’une évaluation des performances homologuée par CSA International.

• BW recommande de contrôler le capteur de gaz combustibles à l’aide d’une concentration connue de gaz d’étalonnage après toute exposition à des contaminants/poisons (composés de soufre, vapeurs de silicium, produits halogénés, etc.).

• Avant chaque utilisation quotidienne, BW recommande d’effectuer un test fonctionnel des capteurs afin de vérifier qu’ils réagissent bien aux gaz présents, en exposant le détecteur à une concentration de gaz supérieure aux seuils d’alarme. Vérifiez manuellement que les alarmes sonore, visuelle et vibrante sont activées. Étalonnez l'appareil si les relevés ne sont pas conformes aux limites spécifiées.

• Pour une mise en garde supplémentaire sur le test fonctionnel en rapport avec le certificat de performances européen, reportez-vous à la section Bump Test.

• Mise en garde : des valeurs LIE élevées hors échelle peuvent indiquer la présence d’une concentration explosive.

Page 9

• 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 Contaminants, page 8.

• Des concentrations élevées en certains gaz toxiques, tels que H capteur LIE. Cet effet, appelé inhibition, est généralement temporaire, mais peut, dans des conditions extrêmes, altérer la sensibilité du capteur LIE.

Après toute exposition à un gaz entraînant le déclenchement d'une alarme des capteurs de gaz toxiques, le capteur LIE devra subir un test fonctionnel et être réétalonné si nécessaire.

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 MicroDock II User Manual.

2. Connect the calibration hose to the intake inlet on the

calibration cap. Arrows on the calibration cap indicate the direction of gas flow.

3. Attach and tighten the calibration cap onto the detector and apply gas. Verify the visual, audible, and vibrator alarms activate.

4. Close the regulator and remove the calibration cap. The detector temporarily remains in alarm until the gas clears from the sensors.

Note: In normal operating mode, it is possible to display measured values with calibration gas applied to determine any measurement errors.

European Performance Approval

Special conditions for safe use

To comply with ATEX performance approval requirements, the detector must be operated in the following manner:

Operating manual: Read and understand the operating manual. It is essential that the instructions for correct use are followed.

Instrument power-up: The instrument must be powered up in a safe area that is free of hazardous gas and in an atmosphere of 20.9% oxygen. The detector must be turned on and verified to be operating in the normal measurement mode before it can be brought into a hazardous area.

Low-battery alarm: In the event of a low-battery alarm, the user must leave the hazardous area immediately.

Operating environment: The operating environment ranges that apply for use of the GasAlertQuattro according to ATEX performance approvals for LEL and oxygen measurements are shown in Specifications on page 26. These specify the climatic range within which the instrument can be used in conformity to the performance certifications.

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

Page 33

Oxygen deficient atmospheres (<10% v/v) may suppress some sensor outputs.

Daily bump test: To comply with performance requirements for European certification, a bump test must be completed before each day’s use.

Calibration: To minimize measuring errors, the ambient conditions of temperature, humidity, and pressure during calibration should be as close as possible to the actual environmental conditions in which the instrument is intended to be used.

Calibration interval: If the detector is to be used in atmospheres which may contain compounds known to interfere with, inhibit, or poison the sensors, the calibration intervals must be specified to take into account the possibility of a rapid loss in measurement sensitivity. See page 7, Sensor Poisons

and Contaminants. Sensor impairment: Some types and concentrations of dust in

the monitored atmosphere may impair the measuring function of the gas detector. Cross-sensitivities described in the sensor manufacturer’s data sheet must be considered.

Response time verification: Before use, confirm that the gas detector’s response time is fast enough to trigger alarms so that unsafe situations are avoided. If necessary, set the alarm levels below the standard safety-related limit values to allow enough time for protective measures to be carried out.

Instrument configuration: FleetManager II version 2.6.0 (or higher) must be used to make configuration changes to the GasAlertQuattro.

European Performance Approval

GasAlertQuattro

To conform with configuration requirements for European gas performance:

• Latching alarms must be enabled. See page 16.

• Stealth mode must be disabled. See page 17.

• Force Bump must be enabled. See page 12.

• Bump Interval (days) must be set to 1 for all sensors.

• IntelliFlash must be enabled. See page 17.

• LEL Low Alarm and High Alarm values cannot be 0.

When detectors are configured using FleetManager II, BW strongly recommends that detector settings are reviewed prior to operation to ensure that they have been applied successfully and comply with performance requirements.

a CAUTION

Do not use for gas detection while connected to a PC. Special conditions for safe use - oxygen measurement Performance approval: The EC type examination certificate
