1.5. Warnings and Cautions – Sensor Use and Care
WARNING: IF THE MONITOR DOES NOT FUNCTION AS DESCRIBED HEREIN,
REMOVE IT FROM SERVICE AND MARK IT FOR MAINTENANCE. ONLY
USE 3M REPLACEMENT PARTS WHERE APPLICABLE.
WARNING: ONLY USE THE MONITOR TO MONITOR THE ATMOSPHERE FOR THE
GASES AND CONCENTRATIONS FOR WHICH IT IS SET-UP TO DETECT.
WARNING: TO PREVENT IGNITION OF AN EXPLOSIVE ATMOSPHERE, READ AND
ADHERE TO THE MANUFACTURER'S LIVE MAINTENANCE PROCEDURES.
WARNING: READ THIS MANUAL FOR INTRINSIC SAFETY PRECAUTIONS.
SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY,
RESULTING IN SERIOUS INJURY OR DEATH.
WARNING: PERFORM A BUMP TEST EVERY DAY. FAILURE TO PERFORM A DAILY
FUNCTIONAL TEST COULD LEAD TO SERIOUS INJURY OR DEATH.
CAUTION: Monitor will not operate without power applied. It ONLY detects gases while
powered.
CAUTION: Periodically test for correct operation of the system's alarm events by
exposing the monitor to a targeted gas concentration above the high alarm
set point.
CAUTION: Verify the gas inlet ports are free of dirt and debris prior to use.
CAUTION: Do not expose the monitor to severe mechanical or electrical shock. Always
conduct device startup and bump test procedures after such exposure to
verify the monitor's operation and accuracy.
WARNING: EXTENDED EXPOSURE OF THE DETECTOR TO HIGH CONCENTRATIONS
OF TOXIC GASES MAY RESULT IN DEGRADED SENSOR PERFORMANCE.
IF AN ALARM OCCURS DUE TO HIGH CONCENTRATION OF TOXIC
GASES, EXIT TO A SAFE AREA, BUMP TEST, RECALIBRATE IF
NECESSARY OR, IF NEEDED, CONTACT THE TECHNICAL SERVICE.
CAUTION: 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 and adhere to the
warnings and cautions indicated here.
