Cautions
•
Warning:
Substitution of components may impair Intrinsic Safety.
• Before using the detector, refer to
Sensor Poisons and Contaminants
•
Caution:
For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and
understand this user manual 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
• Only use sensor(s) that are specifically designed for the GasAlertQuattro. Refer to
.
• 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.
