Set the lock/bipart delay – Chamberlain LA412 User Manual
Page 23
Connect the Gate Operator (Gate 2) to the Control Box (Model LA412-S Only)
Occasionally in dual gate installations, one gate will need to open fi rst 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.
NOTE: The gate with the longer travel span (opening) must be set as the primary gate (GATE 1).

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
confi guration with a decorative overlapping piece on
the outside of the gate.
