Chamberlain GA400D Safety Gate User Manual


 
Occasionally in dual gate installations, one gate would need to open first and close second. This would happen if there
was an ornamental overhang on one gate or if using a solenoid lock, for example. This gate is called the Primary gate
and needs to be connected to Gate 1 connections on the control board. Thus, it is preferred that the control box be
installed on the same side as this gate. If there is no appropriate location on that side for the control box, then mount the
control box on the opposite side, but connect the operator closest to the control box to the Gate 2 connector and the
operator on the opposite side to the Gate 1 connector.
Set the Lock/Bipart Delay
The LOCK/BIPART DELAY switch on the control board
needs to be set to the ON position.
The following illustration shows a dual gate configuration
with a decorative overlapping piece on the outside of the
gate.
