measuring principle:
Capillary controlled concentration sensor
Bump test specified limits:
BW recommends using a gas cylinder that
will ensure the combustible sensor has an accuracy of -0 to +20% of
actual reading (reference CAN/CSA C22.2 No. 152).
Alarm conditions:
TWA alarm, STEL alarm, low alarm, high alarm,
multi-gas alarm, over limit (OL) alarm, low battery alarm, critical low bat-
tery alarm, IntelliFlash, confidence/compliance beep, sensor self-test
failure alarm
Audible alarm:
95 dB+ at 30 cm (12 in.) variable pulsed beeper
Visual alarm:
Red light-emitting diodes (LEDs)
IntelliFlash:
Green light-emitting diode. Flash frequency is user-defined
with the IntelliFlash interval option
Confidence/compliance beep:
Audible beep from variable pulsed
beeper. Beep frequency is dependent upon frequency defined for confi-
dence/compliance beep interval option
Display:
Alphanumeric liquid crystal display (LCD) with flip display
(0° or 180°) capability (user-defined in Fleet Manager II)
Backlight:
Activates upon startup and deactivates when self-test is com-
plete. Activates when the pushbutton is pressed and deactivates after 10
seconds. Activates during an alarm condition and remains lit until alarm
ceases
Internal vibrator:
Vibrates during activation, deactivation, and all alarms
Self-test:
Initiated during activation, self-test runs continuously on the
battery and electrochemical sensors (H
2
S and CO) while detector is
operational
Calibration:
Zero and automatic span
User options:
Startup message, lockout on sensor error, safe mode,
IntelliFlash, confidence/compliance beep, latching alarms, force calibra-
tion, force bump, calibration IR lock, flip display, stealth mode, datalog
interval, IntelliFlash interval, confidence/compliance beep interval, lan-
guage selection.
