CAUTION

•  Substitution of components may impair Intrinsic Safety.
•  For safety reasons, this equipment must be operated and serviced by qualified personnel only.
•  Charge the detector before first time use. Honeywell recommends the detector be charged after every workday.
•  Before using the detector, refer to Sensor Poisons and Contaminants in the User Manual.
•  Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor exposure to poisons and contaminants. 

Honeywell recommends calibrating at least once every 180 days (6 months).

•  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.
•  Calibrate only in a safe area that is free of hazardous gas and in an atmosphere of 20.9% oxygen.
•  It is recommended 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.

•  Honeywell 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 are activated. Calibrate if the readings 

are not within the specified limits.

•  Caution: High off-scale readings may indicate an explosive concentration.
•  Any rapid up scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond the upper scale limit, which 

can be hazardous.

•  Extended exposure of the Honeywell BW™ MicroClip to certain concentrations of combustible gases and air may stress a detector element that 

can seriously affect its performance. If an alarm occurs due to a high concentration of combustible gases, calibrate the detector. If necessary, 

replace the sensor.

•  Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons.
•  Sensor exposure to certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor performance.  

After exposure, a bump test or calibration is recommended.

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

MISES EN GARDE

•  Avertissement : Le remplacement d’un composant de l’appareil peut compromettre la sécurité intrinsèque du détecteur. Mise en garde: Pour des 

raisons de sécurité, cet appareil doit être utilisé et entretenu par du personnel qualifié uniquement. Lisez attentivement le manuel avant d’utiliser 

l’appareil ou d’en assurer l’entretien et assurez-vous d’en avoir bien compris les instructions.

•  Chargez le détecteur avant sa première utilisation. Honeywell recommande de recharger le détecteur après chaque journée d’utilisation.
•  Avant toute utilisation du détecteur, reportez-vous à la section.
•  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. Honeywell recommande d’effectuer un étalonnage au moins une fois tous les 180 jours (6 mois).

•  Le capteur de gaz combustibles est étalonné en usine au méthane, à une concentration de 50 % de la LIE. Si le contrôle porte sur un autre gaz 

combustible dans la plage de % LIE, étalonnez le capteur en utilisant le gaz approprié.

•  Sur cet appareil, seule la détection de gaz combustibles a fait l’objet d’une évaluation des performances par CSA International.
•  Veillez à effectuer l’étalonnage dans une zone sûre, exempte de gaz dangereux, et dans une atmosphère contenant 20,9 % d’oxygène.
•  Si le capteur de gaz combustibles a été exposé à des contaminants/poisons (composés de soufre, vapeurs de silicium, produits halogénés, etc.), 

il est conseillé de vérifier son bon fonctionnement en le mettant en présence d’une concentration connue d’un gaz.

•  Avant chaque utilisation quotidienne, Honeywell 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 et 

visuelle sont activées. Étalonnez l’appareil si les relevés ne sont pas conformes aux limites spécifiées.

•  Mise en garde : Des relevés élevés hors échelle peuvent indiquer la présence d’une concentration explosive.
•  Toute mesure en rapide augmentation suivie d’une diminution ou d’une mesure fantaisiste peut indiquer une concentration de gaz au-delà de la limite 

d’échelle supérieure, risquant donc d’être dangereuse.

•  Une exposition prolongée du Honeywell BW™ MicroClip à certaines concentrations de gaz combustibles et dans certaines atmosphères peut nuire 

à l’élément de détection et altérer gravement ses performances. Étalonnez le détecteur après toute exposition à des concentrations élevées de gaz 

combustibles ayant déclenché son alarme. Si nécessaire, remplacez le capteur.

•  Protégez le capteur de gaz combustibles contre toute exposition aux composés de plomb, aux silicones et aux hydrocarbures chlorés.
•  L’exposition du capteur à certaines vapeurs organiques (comme l’essence au plomb ou les hydrocarbures halogénés) peut altérer temporairement son 

bon fonctionnement. Il est recommandé de procéder à un test fonctionnel ou à un étalonnage après toute exposition.

•  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 produits peuvent contenir des matériaux qui sont réglementés pour le transport en vertu des règlements nationaux et internationaux 

de marchandises dangereuses. Retourner le produit conformément à la réglementation sur les marchandises dangereuses appropriées.
