Safety Information

a CAUTION

READ THIS FIRST

Use the detector only as specified in this manual, otherwise
the protection provided by the detector may be impaired.

• Only the instrument capable of sounding the alarms and showing readings on a
display should be used for immediate safety critical use. Wireless communication
and infrastructure are only for informational monitoring.

• Use only Honeywell approved batteries (order number: HUBAT (P/N:
50122982130) with the Honeywell BW™ Ultra detector. Using any other
battery can cause an explosion or fire.

• The lithium battery in this product presents a risk of fire, explosion, and chemical
burn if misused. Do not open, crush, disassemble, incinerate, or heat above
212°F (100°C). Batteries exposed to heat at 266°F (130°C) for 10 minutes
can cause fire and explosion. Follow the manufacturer’s instruction. Batteries
must only be charged in a hazardous free area.

• Deactivating the detector by removing the battery pack may cause improper
operation and harm the detector.

• Use only Honeywell approved battery charger, that is certified for SELV/LVLC
(isolated) with an output Um of 6.3 V.

• If using the detector near its upper or lower operating temperature, Honeywell
recommends zeroing or activating the detector in that environment.

• Charge the detector before first-time use. Honeywell recommends the detector
also be charged after every workday.

• Calibrate the device on a regular schedule, depending on use and sensor
exposure to poisons and contaminants. Honeywell recommends calibrating at
least once every six months.

• For optimal performance, periodically zero the sensor in a normal atmosphere
(20.9% v/v O) that is free of hazardous gas.

• 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 detector has been assessed
for performance by CSA standard.

• Honeywell recommends that the combustible sensor is checked with a known
concentration of calibration gas after any exposure to contaminants/poisons
such as sulfur compounds, silicone vapors, halogenated compounds, etc.

• Honeywell recommends that the sensors be bump tested before each day’s
use to confirm their ability to respond to gas. Manually verify that the audible,
visual, and vibrator alarms are activated. Calibrate if the readings are not within
the specified limits.

• The detector is designed 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 detector to certain concentrations of combustible
gases and air may stress the detector element and seriously affect its
performance. If an alarm occurs due to a high concentration of combustible
gases, a calibration should be performed. If necessary, contact Honeywell service
representative to replace the sensor.

• High concentrations of certain toxic gases, for example, H2S, may hurt the LEL
sensor. This effect, known as inhibition, is usually temporary but in extreme
circumstances can impair the sensitivity of the LEL sensor after any gas exposure
that causes alarm in the toxic gas sensors.

• The Honeywell BW™ Ultra is provided with an antistatic coating over the LCD
window to minimize the risk of ignition due to electrostatic discharge. Periodic
inspection of this coating is required to ensure no degradation, delamination,
abrasions or other deformities to this surface.

• Care must be taken to avoid exposure to excessive heat, harsh chemicals or
solvents, sharp edges and abrasive surfaces. Clean the exterior with a soft,
damp cloth.

• Portable safety gas detectors are life safety devices. The accuracy of ambient
gas reading(s) is dependent upon factors such as accuracy of the calibration
gas standard used for calibration and frequency of calibration.

• When Honeywell BW™ Ultra detector is equipped with Infrared (IR) sensor, do
NOT use BW Ultra at an atmospheric pressure exceeding 1.1 bar (110 kPa).
The IR sensor used in the detector is intended for use at atmospheric pressure
and shall not be used in pressures exceeding 1.1 bar (110 kPa).

• DO NOT rely on the Bluetooth BW Ultra output indication for security purposes.

a WARNINGS

• FOR SAFETY REASONS THIS EQUIPMENT MUST BE OPERATED AND
SERVICED BY QUALIFIED PERSONNEL ONLY. READ AND UNDERSTAND
INSTRUCTION MANUAL COMPLETELY BEFORE OPERATING OR SERVICING.

• Substitution of components may impair Intrinsic Safety.

• Protect the combustible sensor from exposure to lead compounds, silicones,
and chlorinated hydrocarbons. Although certain organic vapors (such as
leaded gasoline and halogenated hydrocarbons) can temporarily inhibit sensor
performance, in most cases the sensor will recover after calibration.

• The Canadian Standards Association (CSA) requires the LEL sensor to be bump
tested before each day’s use with calibration gas containing between 25%
and 50% LEL. The instrument must be calibrated if the displayed LEL value
during a bump test fails to fall between 100% and 120% of the expected
value for the gas.

• High off-scale LEL 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.

• 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.

• Dispose of used lithium cells immediately. Do not disassemble and do not
dispose of in fire. Do not mix batteries with the solid waste stream. Spent batteries
should be disposed of by a qualified recycler or hazardous materials handler.
Keep children away from the lithium cells.

• The pellistors used in the Catalytic flammable gas sensor can suffer from a
loss of sensitivity when in the presence of poisons or inhibitors, e.g. silicones,
sulphides, chlorine, lead or halogenated hydrocarbons.

• DO NOT rely on the Bluetooth BW Ultra output indication for security purposes.

• DO NOT use the screen protector in the hazardous location. The screen protector
must be removed in the explosive atmospheres.

• The accessories (e.g., fitting mini quick-connector to 1/8”, fitting male Luer-lock
to 1/8” etc.) are not the scope of intrinsic safe certification

• Do not install or remove any components when an explosive gas atmosphere
is present.

Calibrate the detector

Perform a calibration to adjust the sensitivity levels of
sensors and ensure accurate responses to gases.

The detector can be calibrated in two ways:

• Apply gas from a cylinder to the sensors manually through the pump inlet.

• Use an IntelliDoX module.

Before you begin. Move to a normal atmosphere (20.9%
v/v O2) that is free of hazardous gas.

1. Go to the main menu and select > Start Calibration.

2. Press and hold the button for three seconds to display
the Powering Off countdown and continue to hold for

The detector will enter the zero function. The Zeroing
process starts automatically and lasts for five minutes.

Current gas measurements are displayed, and entries
above zero are highlighted.

3. Connect the calibration hose to the pump inlet. Make
sure to use a demand flow regulator.

4. Confirm that you want to apply Nitrogen to zero CO2.

5. When Apply calibration gas now is displayed,
apply the gas and wait for a maximum of five minutes.

The detector first tests for a specific type of gas. When
it detects enough of that gas for sensor calibration, a
check box will be displayed next to that gas. Calibration
then begins. Gas values will adjust on the screen during
the calibration.

6. When Turn gas o is displayed, disconnect the device
from gas. Check marks will be displayed next to the
calibrated sensors. These sensors reset to the number
of days until the next calibration is due (for example,
180 days).
The calibration cycle will take about two minutes after
which the user will be prompted to Press button to
continue.

7. If the calibration was successful, Calibration
Passed will be displayed. Press the button to exit
calibration.
If the calibration failed for some or all of the gases,
either a Cal Error All gases applied mixed
results message (if the detector was not successfully

Set up IntelliFlash

The IntelliFlash® feature causes the detector, if it is in
compliance (for example, bump tested and calibrated),
to flash a green light every second (the factory setting
default) from the top visual alarm indicator. In Fleet
Manager II, use the IntelliFlash Interval option to change
how often the detector flashes.

Set up Reverse IntelliFlash

IntelliFlash flashes a green light when the detector is in
compliance, but Reverse IntelliFlash® flashes an amber
light when the detector is not in compliance (a bump test
or calibration is overdue, or a sensor is not working and has
been overridden).

Use Fleet Manager II to change how often the detector
flashes for Reverse IntelliFlash.

IntelliFlash and Reverse IntelliFlash can be configured in
one of four scenarios:

Scenario 1

When both IntelliFlash and Reverse IntelliFlash are
enabled, the detector’s green LED will flash until it goes out
of compliance, then its amber LED will flash instead.

Scenario 2

If IntelliFlash is enabled and Reverse IntelliFlash is
disabled, the detector’s green LED flashes until it goes out
of compliance, then it stops flashing.

Scenario 3

If IntelliFlash is disabled and Reverse IntelliFlash is
enabled, neither LED will flash while the detector is in
compliance. The amber LED will flash if it goes out of
compliance.

Scenario 4

When both IntelliFlash and Reverse IntelliFlash are
disabled, neither LED will flash under any circumstances.

Set up the Confidence and
Compliance Beep interval

The Confidence Compliance Beep is a sound that tells
the user the detector is in compliance (for example,
bump tested and calibrated). In Fleet Manager II use the
Confidence/Compliance Beep option to change how often
the detector beeps for Confidence Compliance Beep.

a CAUTION

Honeywell 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 the alarm setpoints.

BW Ultra User Manual8

Select an operation mode

The detector can be used in one of three modes: Essentials
mode, Hole Watch mode, and Inert mode.

Note: Honeywell BW™ Ultra always monitors gas levels, regardless of

the operating mode. If the detector detects a sudden gas exposure,
it will flash, vibrate, and produce a loud siren noise. A gas level alarm
takes precedence over all of the detector’s other functions.

Configure the Detector

You can configure the Honeywell BW™ Ultra detector’s
device and sensor using Fleet Manager II.

Necessary to configure detector settings:

• Honeywell BW™ Ultra detector

• IR Link adapter or IntelliDoX docking station

• Computer with Fleet Manager II software installed.

Essentials mode

The detector only shows the gas readings.

Hole Watch mode

The Hole Watch mode is the default operating mode. It is
used for confined space monitoring. Use Hole Watch mode
to monitor all gas levels in the same screen view. Hole
Watch mode uses bar graphs that fill when the detector
detects rising gas concentrations.

• When the detector detects normal gas levels, Hole Watch mode displays
empty bar graphs.

• When the detector detects non-critical gas levels, Hole Watch mode displays
filling bar graphs.

• When the detector activates a single gas alarm, Hole Watch mode highlights
the detected gas level for that gas in a solid bar.

• When the detector activates a multiple gas alarm, Hole Watch mode continues
to display the first detected gas level, as well as highlight other detected gas
levels in a solid bar.

• For oxygen, Hole Watch mode displays low and high levels in a bar graph. As
the detector detects a low oxygen level, the bar graph fills toward LO.

• As the detector detects a high oxygen level, the bar graph fills toward HI.

Inert mode

You can configure Inert Mode in Fleet Manager II. The
threshold for operation is 10%. If oxygen readings fall
below 10%, the detector prompts the user to enter the Inert
mode. The detector does not start automatically in Inert
Mode.

When the detector goes into Inert Mode, the alarms
setpoint get activated. If the detector does not enter in Inert
mode, The O2 readings are considered normal.

For device settings, a startup message can be added;
Confidence Compliance Beep can be activated, bump tests
can be forced, stealth mode can be enabled, etc.

For sensor settings, the calibration gas type and frequency
can be changed, the bump test interval and alarm setpoints
can be set, STEL and TWA can be selected, etc.

You can perform some other calibrations with Fleet
Manager II.

Note: When the operator configures the Honeywell BW™ Ultra using

FleetManager II, Honeywell strongly recommends reviewing the
detector’s settings before the operation to ensure that settings were
applied successfully and comply with performance requirements.

Custom configuration created in Fleet Manager II can be
used to configure detector settings.

Example: Five detectors must have the same bump test
reminders and alarm setpoints. Each detector could be
configured separately or Fleet Manager II can be utilized to
create a custom settings configuration. This configuration
can then be loaded on each detector. This saves time and
allows settings to be managed from one location.

Connect With IntelliDoX

If a detector’s calibration is overdue and the forced
calibration feature is enabled, the calibration can be
performed with an IntelliDoX docking station or through
the calibration option from the detector’s main menu.

Connect With an IR Link

The detector can be paired with an IR link, aka dongle.
There is an IR connection at the bottom of the detector
that allows FleetManager II configurations to be efficiently
transferred to multiple detectors. The IR link will also allow
new firmware to be transferred to detectors or data/event
logs to be transferred to FleetManager II.

Note: You should have the IR Connectivity Kit (sold separately) to
transfer the data from a computer to the detector.

BW Ultra User Manual 9

Bluetooth Pairing

The user can pair the Honeywell BW™ Ultra to a mobile
device via built in Bluetooth Low Energy (BLE). The
Honeywell Safety Communicator app, installed on the
mobile phone, can then show gas readings and alarms
from the Honeywell BW™ Ultra unit that is connected.
Readings and alarms can then be sent to Honeywell’s
remote monitoring software.

1. On the mobile device, turn on the Bluetooth connection
and look for available detectors.
On the Honeywell BW™ Ultra, the Bluetooth connection
is on by default.

2. On the mobile device, select the detector and then enter

100000.

Note: Pairing is not allowed at start up, during calibration, or bump

test.

Warning: Wireless communication and infrastructure
should be used as informational monitoring only.

Replace a Sensor

Use only sensors designed by Honeywell for the
Honeywell BW™ Ultra detectors. Replace the sensors in a
non-hazardous location.

The Honeywell BW™ Ultra detector can be configured for a
maximum of 5 gases and may contain dummy sensors.

Review Logs

Many of the detector events are logged and can be
reviewed via IntelliDoX or BLE. Typical logged events would
be:

• bump test failed • self-test failed

• last calibration failed • calibration overdue

• calibration forced • calibration canceled

• calibration error • calibration passed

• sensors in alarm • system reset

• sensors zeroed • event logs vs. data logs

• “Turn cal gas off...” message is displayed

BW Ultra User Manual10

Maintenance

Maintenance

Perform the following tasks to maintain the detector in
good operating condition:

• Calibrate, bump test, and inspect the detector on a regular schedule.

• Maintain an operations log of all maintenance, bump tests, calibrations, and
alarm events.

• Keep the exterior of the detector clean.

Gas Cylinder Guidelines

• Use a premium-grade calibration gas that is approved by the National Institute
of Standards and Technology.

• Verify the expiration date on the cylinder before use.

• Do not use an expired gas cylinder.

Glossary

ACGIH

The ACGIH method is defined as the infinite (total) accumulated average,
whether it is 2 hours or 8 hours.

BLE

Bluetooth Low Energy.

Bump test

A compliance test that confirms the detector’s ability to respond to target
gases by exposing the detector to a known gas concentration. Other
procedures that are specified to occur automatically when the detector is
inserted into a docking module may be performed in conjunction with the
bump test.

Calibration

A two-step compliance test that determines the measurement scale for the
detector’s response to gas. In the first step, a baseline reading is taken in a
clean, uncontaminated environment. In the second step, the sensors are
exposed to known concentrations of gas. The detector uses the baseline
and known gas concentrations to determine the measurement scale.

Datalog

A datalog is a file that contains detailed, date-stamped records related to
detector operations and configuration settings. The datalog is continuously
updated. Records that span the operating life of the detector are retained.

Event log

An event log is a file that contains detailed, time-stamped records data
related to gas events, and compliance tests. The event log is updated when
an event occurs. A specified number records for the most recent events are
retained.

Fleet Manager

A proprietary, Windows-based software developed by Honeywell to
configure and manage docking modules, calibration, bump tests, and data
logs. Fleet Manager II is available for download from
www.honeywellanalytics.com

Gang

A group of two to five connected IntelliDoX modules. Modules that are
connected share power, network and gas connections.

IntelliDoX Docking Module

An automatic bump test and calibration docking station for use with
portable gas detectors manufactured by Honeywell.

Normal atmosphere

A fresh air environment with 20.9% v/v oxygen (O) that is free of
hazardous gas

Operating Life

The period of operational use required to attain the specified operating
limit. Operating life includes normal operating time, alarm time, and all
types of idle time.

OSHA

The US OSHA method is defined as a moving average that accumulates
over an 8-hour average. If the worker is in the field longer, the oldest
accumulated values (first hour) are replaced by the newest values (ninth
hour). This continues for the duration of the work shift until the detector is
deactivated.

PPM

Parts per million, a measure of concentration.

Reboot

Restart the operating system for the module

Service Life

The expected lifetime of a product, as specified by the manufacturer.

Station

An area or zone dedicated to a specific activity. A compliance testing station
may contain several IntelliDoX modules and gangs of connected modules.

Stealth mode

When enabled, the backlight, visual alarms, and audible alarms are
disabled. During an alarm, the vibrator activates and readings are displayed
on the LCD.

STEL

The ShortTerm exposure Limit is the maximum permissible gas
concentration a worker can be safely exposed to for short periods of time
(515 minutes maximum).

TWA Alarm

The time-weighted average (TWA) is a safety measure used to calculate
accumulated averages of gases. Using the US Occupational Safety and
Health Administration (OSHA) method or the American Conference of
Governmental Hygienists (ACGIH) method, an average is calculated to
ensure the detector alarms when the TWA has accumulated.

IR

Infrared. IR is an invisible radiant energy that can be used for short- range
wireless communications between enabled devices.

V/V

Volume percent concentration.

LCD

Liquid crystal display. LCD is a technology that is commonly used for
display screens on mobile digital devices.
