SINGLE-GAS DETECTOR
Activate a New Detector
1. Move to a normal atmosphere (20.9% v/v O
2
) that is free of hazardous
gas.
2. Press and hold the pushbutton until a 5 second countdown is displayed,
and then continue to hold until the countdown is complete.
3. When the countdown is complete, the LCD and LEDs turn on and then
turn off. The detector performs an internal diagnostic test.
4. When the diagnostic test is successful, the alarm setpoints are
displayed and the LEDs ash.
5. The sensor stabilization countdown is displayed. During the countdown,
the detector vibrates continuously for 20 seconds. The time required
to stabilize varies depending on sensor type. When the countdown
reaches 0, the LEDs ash and the audible alarm beeps.
6. When the type of gas detected and the operating life countdown are
displayed, the detector is in normal operating mode.
Normal Operating Mode
When the detector is in normal operating mode, the type
of gas detected is permanently displayed. The remaining
operating life is displayed until it is disrupted by a
pushbutton action, gas alarm, or error event.
Operating Life
When the detector is activated for the rst time, the
operating life countdown is displayed. The countdown
displays remaining operating life in months until the
countdown reaches 90 days or less before expiry.
90 Days or Less Remaining
When the operating life countdown reaches 90 days or
less before expiry, the countdown display changes to
days. The countdown displays the remaining operating
life in days until the countdown reaches 24 hours or less
before expiry.
24 Hours or Less Remaining
When the operating life countdown reaches 24 hours or
less before expiry, the countdown display changes to
hours, and the EXPIRY! warning and non-compliance
symbol are displayed.
End of Operating Life
When the operating life countdown ends, the detector
deactivates and detector safety functions are disabled. It
is possible to retrieve event logs for a limited time after
expiry. The EXPIRY! warning and non-compliance symbol
are displayed for up to 30 days after expiry.
Internal Diagnostic Tests
Activated detectors automatically perform one internal diagnostic test every
24 hours. If the internal diagnostic test fails, the diagnostic fail-safe begins.
Diagnostic Fail-Safe
1. The EXPIRY! warning and non-compliance symbol are displayed.
2. The detector beeps and vibrates.
3. The LEDs ash 2 times per second for 15 seconds.
4. OFF or an error code is displayed. The detector is deactivated.
It is possible to retrieve the event logs for a limited time after expiry. If you
are unable to retrieve the event logs, contact BW.
Alarms and Warnings
An alarm is initiated when the sensor is exposed to a gas concentration
that exceeds alarm setpoints. The alarm persists until the alarm
gas concentration returns to an acceptable range. You can use
Fleet Manager II via an IntelliDoX station to enable the display of the gas
concentration reading during an alarm. Battery life decreases rapidly when
the detector is in alarm condition.
Low Alarm
Audible: 1 beep per second
Visual: 1 ash per second
Vibration: 1 vibration per second
High Alarm
Audible: 2 beeps per second
Visual: 2 ashes per second
Vibration: 2 vibrations per second
Over-Limit and Under-Limit Alarms
If the gas concentration is beyond the sensor range, OL
(over-limit) or -OL (under-limit) is displayed.
Audible: 2 beeps per second
Visual: 2 ashes per second
Vibration: 2 vibrations per second
Automatic Zero Reminder for O
2
Models
For O
2
models only, the Automatic Zero Reminder is
displayed when more than 24 hours have elapsed since
the last successful zero procedure was performed.
Peak Readings
The peak readings symbol is displayed when the sensor
is exposed to a gas concentration that exceeds the alarm
setpoints. It is no longer displayed when more than
24 hours have passed since the last alarm, or when a
successful bump test is performed via an IntelliDoX or MicroDock II station.
Non-compliance Symbol and LED Indicators
The non-compliance warning symbol is displayed when:
• an internal diagnostic test fails;
• a bump test or zero procedure fails;
• a bump test is due, if enabled;
• the sensor is exposed to a gas concentration that exceeds alarm
setpoints, if enabled.
The non-compliance warning symbol is no longer displayed when more
than 24 hours have passed since the last alarm, or when a successful
bump test is performed via an IntelliDoX or MicroDock II station. The non-
compliance warning symbol is permanently displayed when the service-life
countdown reaches 24 hours or less before expiry, and for up to 30 days
after expiry.
When Non-compliance after gas exposure is enabled through
Fleet Manager II via an IntelliDoX station, the LEDs ash in an alternating
pattern when the non-compliance warning symbol is displayed. When the
symbol is rst displayed, the top LEDs ash. After 30 seconds, the side
LEDs ash. After 30 seconds, the pattern repeats until the non-compliance
warning symbol is no longer displayed.
NOTE: When the detector is bump tested via a MicroDock II station, an
abnormal test result may occur if non-compliance LEDs are ashing.
To suspend the ashing for up to 10 minutes, press and release the
pushbutton. When the ashing stops, insert the detector and perform the
test. If the bump test fails, the LEDs resume ashing.
