Introduction

The Honeywell BW ™ Ultra gas detector warns of

hazardous gas at levels above user-deﬁned alarm

setpoints.

The detector is a personal safety device. It is your

responsibility to respond properly to the alarm.

Monitored Gases

The detector can monitor up to ﬁve gases at a time.

Refer to the Honeywell BW ™ Ultra User Manual for the full

list of gases.

Safety Information

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.

• Useonly HoneywellHUBATbatterypack.Usinganyotherbatterycancause

an explosion or ﬁre.

• Deactivatingthedetectorbyremovingthebatterypackmaycauseimproper

operation and harm the detector.

• Use only Honeywell approved battery chargers such as the MultiUnit

Cradle Charger.

• Ifusingthedetectornearitsupperorloweroperatingtemperature,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.

• Foroptimalperformance,periodicallyzerothesensorinanormalatmosphere

(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.

• Onlythecombustiblegasdetectionportionofthisdetectorhasbeenassessed

for performance by CSA International.

• Honeywellrecommendsthatthecombustiblesensorischeckedwithaknown

such as sulfur compounds, silicone vapors, halogenated compounds, etc.

ENGLISH

• Honeywell recommends that the sensors be bump tested before each day’s

usetoconﬁrmtheirabilitytorespondtogas.Manuallyverifythattheaudible,

visual, and vibrator alarms are activated. Calibrate if the readings are not

within the speciﬁed limits.

• Portablesafetygasdetectorsarelifesafetydevices.Theaccuracyofambient

gasreading(s)isdependentuponfactorssuchasaccuracyofthecalibration

gas standard used for calibration and frequency of calibration.

• 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.

• Extendedexposureofthedetectortocertainconcentrations ofcombustible

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, 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.

• TheHoneywellBW™UltraisprovidedwithanantistaticcoatingovertheLCD

windowtominimizetheriskofignitionduetoelectrostaticdischarge.Periodic

inspectionofthiscoatingisrequiredtoensurenodegradation,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.

• 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.

aWARNINGS

• Warning: Substitution of components may impair Intrinsic Safety.

• To prevent ignition of ﬂammable or combustible atmospheres, disconnect

power before servicing.

• Protectthecombustiblesensorfromexposuretoleadcompounds,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.

• Caution:Highoff-scaleLELreadingsmayindicateanexplosiveconcentration.

• 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

domesticandinternational dangerousgoodsregulations. Return productin

compliance with appropriate dangerous goods regulations. Contact freight

carrier for further instructions.

• The lithium battery may present a risk of ﬁre or chemical burn hazard if

misused. Do not disassemble, incinerate, or heat above 212°F (100°C), or

incinerate.Batteries must only be charged in a safe area free of hazardous

gas.Batterieseexposedto heatat266°F(130°C)for10minutescancause

ﬁre and explosion.

• Disposeofusedlithiumcellsimmediately.Donotmixbatteries withthesolid

waste stream. Spent batteries should be disposed of by a qualiﬁed recycler

or hazardous materials handler.

Activate the Detector

Activate the detector in a safe area with an atmosphere of

20.9% oxygen and free of hazardous gas.

1. For ﬁrst time use, charge the battery for up to 8 hours or

until LED light turns green using the charging adapter

provided. Refer to Charge the battery for more information.

2. Press and hold the button for three seconds.

3. For ﬁrst time use, a Warming sensors message is

displayed and a 30 minutes countdown is displayed. In

most cases, this countdown only lasts a couple of minutes.

4. When the detector displays Pump test Block inlet,

block the pump inlet with a ﬁnger, and then after a couple

of seconds unblock the pump inlet.

The detector performs a quick pump test. A Pump Test

passed message is displayed.

If you do not block the pump inlet, the detector will turn off

after two minutes.

If necessary, you will be instructed by screen prompts to

calibrate newly-installed sensors.

The detector will then perform a self-test, including testing

the sensors. This process could take several minutes.

5. When the self-test is complete, press and hold the button

to zero sensors. After the autozero is complete, the detector

then checks the sensors for calibration and bump test.

If the detector identiﬁes sensors requiring calibration or

bump testing, press the button and follow the on-screen

instructions.
