Specifications

Setup and Installation

Installing the LiftMaster LA400 system involves mounting the actuator arms to your gate and gate posts, and connecting them to the control box. For dual gate setups, one arm is installed on each gate leaf.

Mounting the Actuator Arms

The actuator arms should be securely mounted to both the gate frame and a sturdy gate post. Ensure proper alignment to allow for smooth gate movement. The system is designed for straightforward mounting, typically involving bolting the arms to the gate and post.

Control Box Placement and Electrical Connections

The control box, which houses the electrical components and battery backup, should be mounted in a secure location, typically near one of the gate posts. All electrical connections from the actuators and photo eye will route to this box. The control box is designed to withstand various weather conditions, including rain and storms.

Photo Eye Installation

Install the photo sensors on the outside of the gate, ensuring they are aligned to create a beam across the gate's opening. This sensor detects when a vehicle or person passes through, triggering safety features. One part of the photo eye acts as a reflector, and the other as the sensor.

Important Note: For outswing applications, the LiftMaster PUSH TO OPEN Bracket Kit is required and is NOT included with this package. Additionally, for advanced programming features or accessories such as external loops, plug-in loops, auxiliary relays, and inputs, an optional Expansion Control Board is needed and is NOT included.

Operating Instructions

Your LiftMaster LA400 gate operator is designed for user-friendly operation.

• Remote Control Operation: Use the provided remote controls to open and close your gate. Keep the remote in your vehicle for convenient access.
• myQ App Integration: For enhanced control, integrate your gate system with the myQ smartphone app. This allows you to open/close the gate, receive real-time alerts on gate status, and manage access from any location with internet connectivity.
• Safety Features: The integrated photo eye ensures that the gate will not close if an obstruction is detected in its path. The Quick Close feature (with optional expansion board) allows the gate to close rapidly after a vehicle passes, enhancing security.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your LiftMaster LA400 gate operator.

• Inspect Actuator Arms: Periodically check the actuator arms for any signs of wear, damage, or loose connections. Ensure they move freely without obstruction.

• Check Electrical Connections: Verify that all electrical connections within the control box and to the actuators are secure and free from corrosion.
• Battery Check: If you experience power outages, ensure the battery backup is functioning correctly. Consult the full product manual for battery testing and replacement procedures.
