European Performance Approval - Honeywell GasAlertQuattro Operator's Manual

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 28. 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).
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.

European Performance Approval
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.
To conform with configuration requirements for European gas
performance:
• Latching alarms must be enabled. See page 17.
• Stealth mode must be disabled. See page 18.
• Force Bump must be enabled. See page 12.
