• When a bump test has failed
, the current bump test status will show: “
L . BUMP FAILED
” (indicating
that the last bump test had failed) . Audible, visual & vibrating prompting to apply gas will automatically
start . The display will alternate between “
BUMP DUE
” and “
APPLY GAS
” . Snap the MGC Calibration Cap
(provided with the detector) into place over the sensor ports . Apply gas to the detector at a flow rate of
0 .25 to 0 .5 LPM and do not disturb while test is being performed . Once all of the sensors have been tested,
the detector will go into alarm . Remove the MGC Calibration Cap and the detector will return to normal
operation after a short period of time . The bump test will be recorded in the Bump Log .
If a sensor fails the bump test, display will show “
Err
” and designate which sensor did not pass . The failed
sensor will be disabled and will need to be replaced (see “
Err
” in
Failures/FAQ’s
section) .
• During a manual bump test, the audible, visual & vibrating prompting to apply gas will continue for
approximately two minutes . If gas is not applied within the two minutes, then the bump test will
automatically fail . The prompts will cease, the detector will return to normal operation, but the display
will continually flash “
BUMP DUE
” until the detector has been successfully bump tested . Please note, to
abort a bump test at any time, press the power/menu button once and the detector will return to normal
operation .
Note - Users may simply apply gas to the detector at any time during normal operation to run a
bump test without going through the steps above. Be aware, this will not be recognized by the
detector as a Manual Bump Test therefore it will be recorded into the Event Log as an Event, not into
the Bump Log as a Bump Test.
