PLEASE NOTE
: Because of the various mounting applications, no mounting hardware is
provided
with the GTO Automatic Gate Lock. All necessary mounting hardware can be ob-
tained from your local hardware store; all other hardware is provided.
This manual shows two examples of the most common installations, and should provide insight
into most other applications. If you have any questions during installation, please call (850)
575-0176 for technical support.

AUTOMATIC
GATE LOCK
®
IMPORTANT:
Before you install the automatic gate lock be sure your gate is level, moves freely on its
hinges, and does not bind or drag against the ground. 1
Be sure you have all the parts:
A - Lock with 20' of low voltage wire
B - Lock Receiver
C - Clevis Pin
D - Locking Cap
E - Lock Board Battery Lead Wires
F - White Wire
(motor lead to lock board)
G - Lock Control Board
H - 2 Double Spade Tongue terminals
I - 6 nylon cable ties
J - 3M
®
Scotch Loc
K - Lock Keys (for manual release)
L - Lock Decal
What else do you need?
Mounting hardware is not included. Read these instructions completely and review the installation examples to
determine the mounting hardware required for your application.
NOTE:
The GTO Lock is designed to use mounting hardware up to
5
/
16
"
in diameter. For a more secure installation,
use lock washers and lock nuts on all mounting hardware.
For most IRON or ALUMINUM TUBE gates you will need:
Bolts, washers, and nuts for the lock and receiver. (see Illustration B, page 3)
For most CHAIN LINK gates you will need:
U-Bolts, saddles or bolts, washers and nuts for the lock.
Bolts, washers, and nuts for the receiver. (see Illustration C, page 3)
The installation has two parts:
(1) Mounting The Lock
(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 work properly, the gate must close firmly 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 Mighty Mule E-Z Gate Opener
®
may require slight movement of the stroke
adjustment knob (and changes to the obstruction sensitivityon Generation 2000 Control Boards ONLY). See Setting
the Gate Closed Position
in your Mighty Mule Installation Manual for information on these adjustments.
Installing the lock with a GTO/PRO gate opener may require slight movement of the stroke adjustment knob
and changes to the obstruction sensitivity (see your GTO/PRO Installation Manual for information on these
adjustments).
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. Contact the GTO Service Department at (850) 575-0176 for assistance.

Mounting The Lock:
Disconnect gate opener by removing hairpin clip and clevis pin from the gate bracket end of the
opener. Disconnecting the opener will allow the gate to swing freely during installation of the gate
lock. If you have a dual gate system, be sure to disconnect both gate openers.
Step 1:
With the gate in the closed position, determine the best location for the lock and lock receiver. The lock
and receiver must be level and aligned with the opener. Also, the lock should have a solid surface or
cross member to provide stability.
Step 2
:
Clamp receiver and lock together (with receiver pin hole and lock slot aligned) against the gate post and
mark their positions to drill receiver holes (see Illustration B and C, page 3). The receiver must be
mounted with through bolts, not U-bolts, to allow lock to seat properly. Fasten the receiver to the gate
post.
Step 3:
Recheck the lock position and alignment, then mark its position for drill holes. Drill the holes on gate
supports through the slots in the lock bracket. U-bolts and saddles can be used to mount the lock on
chain link gate supports. Secure the lock to the gate. Install clevis pin and locking cap by placing clevis
pin through slots in lock receiver and hammering the clevis pin into the locking cap (see Illustration D),
and check the alignment again.
Manual Lock Release:
The GTO Automatic Gate Lock is keyed for manual release. Should the electronic release be disabled for any
reason, simply use the key to manually open the lock.
Receiver pin hole and lock slot must line up.
Check alignment with pin out of receiver.
Lock and receiver must be level
and aligned with opener. 3

* Place a dab of petroleum

tacts to prevent corrosion.
Step 1.
Turn control box power switch OFF and unplug the transformer. Remove control box cover
and disconnect battery lead wires from the battery terminals before wiring the lock board.
Step 2.
Connect the WHITE wire (included) to Terminal #1 on the lock board. Connect the RED
battery lead wire (included) to Terminal #5 on the lock board. Connect the BLACK Battery lead
wire (included) to Terminal #2 on the lock board. (See Wiring Chart). DO NOT connect lock
board battery lead wires to battery until Step 6!
Step 3.
Attach the RED control board battery lead wire to one spade tongue on a double spade tongue
connector (included). Attach the BLACK control board battery lead wire to one spade tongue
on the other double spade tongue connector (included).
Refer to the appropriate diagram for your opener (on pages 57) and the Wiring
Chart on this page as you follow these steps.
PLEASE NOTE:
If a diagram of your control board
and control box is not pictured on
page 5 please call the GTO
ServiceDepartment at (800) 543-
4283 or (850) 575-0176 for assis-
tance.
NOTE:
The 3M
®
Scotch Loc Connector is not needed with Generation 2000 Control Boards. If
you have a Generation 2000 Control Board, skip step 4 and refer to the illustration on page 6.
Step 4.
Attach the 3M
®
Scotch Loc Connector. Place the WHITE wire from the lock board inside the
blocked channel on the 3M
®
Scotch Loc Connector. If the gate opens into the property (pull-
to-open
), place the BLACK wire from the opener power cable inside the through channel on
the 3M
®
Scotch Loc Connector. Crimp the 3M
®
Scotch Loc closed with pliers and fold plastic
locking tab into place until it locks shut.
NOTE:
If the gate opens away from the property (push-to-open) place the RED wire from the opener
power cable inside the through channel on the 3M
®
Scotch Loc Connector. Crimp 3M
®
Scotch Loc closed with pliers and fold plastic locking tab into place until it locks shut.
If this is a dual gate installation, use the RED (push-to-open) or BLACK (pull-to-open) wire
that extends from the power cable to the opener. The opener must be mounted on the same gate
leaf that the lock is mounted to. This gate leaf must also be set to open first; see your Installa-
tion Manual for information about gate sequencing.
Step 5.
Pull RED and BLACK wires from gate lock through the strain relief and into the control box.
Attach BLACK wire to Terminal #3 on lock board. Attach RED wire to Terminal #4 on lock
board (see Wiring Chart).
Step 6.
Attach RED lock board battery lead wire to the double spade tongue terminal with the RED
control board lead wire. Attach the BLACK lock board battery lead wire to the double spade
tongue connector with the BLACK control board Lead Wire.
Step 7.
Reconnect opener to gate bracket. Connect RED wires (with double spade tongue terminal) to
POSITIVE (+)
battery terminal and the BLACK wires (with double spade tongue terminal) to
the NEGATIVE () battery terminal. Plug the transformer in and turn the control box power
switch ON. Test opener and lock to make sure it functions properly and make adjustments if
necessary. 5
