# Before You Begin...
For the 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 adjusting limits and stall force.
Refer to your individual 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. Contact the Nortek Control Technical Service Department at (800) 543-1236 for assistance if needed.
NOTE: Positive stops are required for dual gate applications.

# Installing The Gate Lock
NOTE: The Automatic Gate Lock can be installed on single and dual gate systems. Use the appropriate instructions for the system you have - **SINGLE GATE** (below) or **DUAL GATES** (page 5).
# Single Gate Installation
Turn power switch OFF on the bottom of the control box. 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.
| | |
|---|---|
| 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 (see *Illustration A* below). |
| Step 2: | Clamp receiver and lock together (with receiver pin hole and lock slot aligned) against the gate post, mark their positions to drill receiver holes (see *Illustration B and C, page 4*). The receiver must be mounted with carriage bolts, not U-bolts, to allow lock to seat properly. Fasten the receiver to the gate post. |
| Step 3: | Hold latch open with key to operate gate and check closed limit and lock alignment. Drop pin in receiver but don’t put the cap on. Recheck the lock’s position and alignment, then mark its position for drilling holes. |
| Step 4: | 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*), secure the lock bracket and check the alignment again. |

# Dual Gate Installation
Turn power switch OFF on the bottom of the control box. Disconnect gate openers by removing hairpin clip and clevis pin from the gate bracket end of the openers. Disconnecting the openers will allow the gates to swing freely during installation of the gate lock.
**NOTE:** In a DUAL GATE INSTALLATION the gate opener on the same side of the driveway as the control box is known as the PRIMARY GATE OPENER and that gate is referred to as the PRIMARY GATE. Conversely the gate opener on the other gate is referred to as the SECONDARY GATE OPENER and the gate is referred to as the SECONDARY GATE.
**IMPORTANT:** To use the gate lock on a dual gate system, the gate sequencing must be set so the PRIMARY GATE opens first and closes last, and the gate lock has to be mounted on the PRIMARY GATE and the lock receiver is mounted on the SECONDARY GATE. Some Linear and Mighty Mule gate operators are preprogrammed with this functionality. The secondary gate requires a positive stop. If your gates are not sequenced in a manner that works like this, you'll have to change the sequencing on your gate opener. Follow the instructions in your gate opener installation manual for programming dual gate sequencing.
| | |
|---|---|
| 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 (see illustration below). |
| Step 2: | Clamp receiver and lock together (with receiver pin hole and lock slot aligned) to the gates, mark their positions to drill holes. The receiver must be mounted on the SECONDARY GATE with carriage bolts, not U-bolts, to allow lock to seat properly. |
| Step 3: | Recheck the lock’s position and alignment. Hold latch open with key and operate gate. 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 PRIMARY 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, secure the lock bracket and check the alignment again. |
> Figure: Diagram of two closed swing gates. The left gate is labeled **SECONDARY GATE** and the right gate is labeled **PRIMARY GATE**. A gate opener is shown on each gate, with the control box on the far right. The automatic lock and receiver meet at the center of the gates.

# Troubleshooting
If lock hangs up and does not latch properly try the following steps before contacting Technical Support:
- Reset closed position limit so gate is snug against stop plate
- Lubricate latch with silicone spray to help latch to operate freely
- Check alignment of lock by using the key to hold the latch open while operating the gate opener
If lock still does not operate properly, contact Technical Support:
Technical Support: (800) 543-1236
**IMPORTANT:** For the optimum service and safety, find the ideal stall force sensing setting for your gate opener. Depending on the weight of your gate, the ideal setting will be just enough to move your gate without self-obstruction (stopping or reversing due to its own weight), yet sensitive enough to reverse and stop when it meets with an obstruction such as a car. See the Gate Opener Installation Manual for information on obstruction settings.
**NOTE:** Be sure your gate moves freely on its hinges without binding or dragging.
