• 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”. Clip the MGC-S Calibration Cap (provided with the detector)
into place over the sensor ports. Apply gas to the detector at a flow rate of 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-S
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.
Under no circumstances should a detector that has failed a bump test be used .
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.
If a sensor fails the bump test, display will show “ERROR” and designate which sensor (CO, H2S, O2 or LEL) did not
pass (see "ERROR" display screens below).
