Chamberlain LA412 Safety Gate User Manual


 
NOTES:
The gate with the longer travel span (opening) must be set as the primary gate (GATE 1).
If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other
gate; gate 2 may need to be closed fi rst if there is overlap or a gate lock is being used.
The programming can be exited at any time by pressing the RESET button. Programming times-out automatically after 60 seconds of
inactivity.
