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. Open de Device Configurator APP.
2. Select Device List.
3. Scan for Instruments.
4. Select the detector and then enter the detector's 100000
pairing code used by default by the BW Ultra.
: Pairing is not allowed at start up, during calibration, or bump test.
Note
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.
If an HCN is set up on the 5th, after cal/bump, the device
enters to high alarm (HCN) this is due to high cross
sensitivity. The type of sensor can only be configured at
factory during assembly process.
Due to above, the user request a BW Ultra with a dummy
sensor in the Analog sensor position, then this dummy
position will not be able to configure and install an analog
sensor. This will prevent that a wrong sensor type can be
installed in the device

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
• last calibration failed
• calibration forced
• calibration error
• sensors in alarm
• sensors zeroed
• "Turn cal gas off..." message is displayed
12
• self-test failed
• calibration overdue
• calibration canceled
• calibration passed
• system reset
• event logs vs. data logs

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.
• Contact Honeywell if a certified calibration of the detector is required.

Charge the Battery

You can charge the battery using the provided charging
adapter, that is certified for SELV/LVLC (isolated) with an
output Um of 6.3 V.
It can take up to 8 hours to get the battery fully charged in
a temperature range from 5 °C to 35 °C.
Note: If you charge with the power on, charging may not be completed
within 8 hours.

Maintain the Battery

Lithium-ion batteries do not respond well to cycles of full
discharge followed by a full charging cycle. Recharge the
battery before it is exhausted.
Do not charge the battery at low or elevated temperatures.
30°C (86ºF) is considered an elevated temperature and
should be avoided whenever possible.
A rechargeable battery's runtime decreases approximately
20% over a two-year period of typical use.

Real Time Clock Display

The real time clock is displayed in the upper left corner
of the detector's screen. It is configurable through Safety
Suite Device Configurator in 12- or 24-hour formats.
The date display can also be configured in several formats
through Safety Suite Device Configurator.
The time/date information is retained even when the
detector's battery is being changed.
