The installation has two parts:
(1) Mounting The Lock and Lock Receiver
(2) Connecting the Control Boards
Once you have the necessary mounting hardware, you can begin the installation.
Before You Start...
For the GTO Automatic Gate Lock to work properly, the gate must close firmly against a positive stop and
engage the lock catch against the lock receiver. Achieving optimal closure may require slight adjustments to
the gate opener settings.
Installing the lock with the Gate Opener may require resetting closed limits and changes to the stall force.
See Setting the Gate Closed Position in your Gate Opener Installation Manual for information on these
adjustments.
Set the limits so that the arm holds the gate snug against the stop in the closed position. IMPORTANT: You
may need to spray the locking mechanism with silicone spray initially to help the latch move freely.
If you are installing the lock on a Push-to-Open gate (gate opens out), the lock must be installed on the outside
of the gate. Depending upon the installation, the gate post may need to be "pocketed" to accommodate the
lock receiver or you may want to purchase the column mount receiver. Contact the GTO Technical Service
Department at (850) 575-4144 for assistance if needed.
NOTE: Positive stops are required for dual gate applications.
