DETECTOR MAINTENANCE
Bump Testing
The detector can be configured to keep track of regular bump testing intervals in a Bump Log . The interval can be
individually adjusted for each sensor from 1 to 365 days, default is 0 (disabled) . When a programmed bump test comes
due, or if the last bump test has failed, then the detector’s display will continually flash “
BUMP DUE
” until the detector
has been successfully bump tested . If the detector is turned off, the “
BUMP DUE
” prompt will reappear again once the
detector is reactivated and continue until a bump test is successfully completed . Performing a bump test that will be
recorded in the Bump Log can be done either automatically: insert the detector into the MGC Dock or MGC Wall Mount
Dock, or manually: apply gas according to the
Manual Bump Test
Instructions described below .
