Description
LiftMaster LA400DCS 24VDC Replacement Secondary Swing Gate Operator Actuator Arm
The LiftMaster LA400DCS 24VDC Replacement Secondary Swing Gate Operator Actuator Arm is a genuine LiftMaster secondary actuator designed for compatible LA400 residential dual swing gate operator systems. It operates the second gate leaf in a dual-gate installation and works in conjunction with the primary LA400 actuator and compatible LA400 control system.
The LA400DCS is used to convert or configure a compatible LA400 system for dual swing gate operation, providing the actuator required to automate the second gate leaf. LiftMaster identifies the dual LA400 configuration as the LA400PKGU combined with the LA400DCS secondary actuator.
Built around LiftMaster's 24VDC residential linear actuator platform, the LA400 system is designed for compatible residential swing gates up to 16 ft. long or 850 lbs. The platform incorporates battery backup, Security+ 2.0® technology, safety reversing functionality, and support for wireless dual-gate communication.
For an existing dual LA400 installation where the secondary actuator has become damaged, worn, or failed but the primary operator, control equipment, batteries, and other components remain serviceable, the LA400DCS provides a direct replacement option without requiring replacement of the complete gate operator system.

What's Included
- (1) LiftMaster LA400DCS 24VDC Secondary Actuator Arm

Compatibility
The LiftMaster LA400DCS is designed for compatible LiftMaster LA400 residential dual swing gate operator systems.
LiftMaster documentation identifies the LA400PKGU + LA400DCS combination as its dual-gate LA400 configuration.
Always verify the existing operator model, actuator model, and installation requirements before ordering replacement equipment.
Why Choose the LiftMaster LA400DCS?
The LiftMaster LA400DCS provides an OEM solution for adding or replacing the secondary actuator in a compatible LA400 dual swing gate system.
For an existing installation, this allows an installer to replace the secondary actuator without unnecessarily replacing the complete LA400 operator system when the remaining equipment is still serviceable.
The distinction between the two LA400 actuator roles is important:
LA400DC = Primary Actuator
LA400DCS = Secondary Actuator
The primary system operates the first gate leaf and contains the primary control architecture, while the LA400DCS provides powered operation of the second gate leaf in the compatible dual-gate configuration.
Because the LA400 platform supports gates up to 16 ft. or 850 lbs., it provides a strong residential solution for single and dual swing gate entrances.
LiftMaster LA400DCS Frequently Asked Questions
What is the LiftMaster LA400DCS?
The LiftMaster LA400DCS is the secondary actuator arm used to automate the second gate leaf in a compatible LiftMaster LA400 dual swing gate operator system.
It works with the primary LA400 system to create a dual-gate configuration. LiftMaster identifies LA400PKGU + LA400DCS as its dual LA400 configuration.
Is the LA400DCS a complete gate operator?
No. The LA400DCS is the secondary actuator arm, not a complete gate operator package.
It does not include the primary actuator, complete control system, batteries, access-control equipment, monitored entrapment protection devices, or other equipment required for a complete automatic gate installation.
Is the LA400DCS the primary or secondary actuator?
The LA400DCS is the secondary actuator.
For the primary actuator, use the LiftMaster LA400DC 24VDC Replacement Primary Swing Gate Operator Actuator Arm.
What is the difference between LA400DC and LA400DCS?
The primary difference is their role within the gate system:
LA400DC — Primary Actuator
LA400DCS — Secondary Actuator
The LA400DC operates as the primary actuator, while the LA400DCS operates the second gate leaf in a compatible dual swing gate installation.
Can I use the LA400DCS by itself for a single swing gate?
The LA400DCS is intended as the secondary actuator for a compatible dual LA400 configuration. For a single-gate LA400 system, the appropriate primary actuator and control equipment should be used.
What size gates can the LA400 system operate?
LiftMaster rates the LA400 platform for compatible residential swing gates up to 16 ft. long or 850 lbs.
Gate length and weight are only part of proper operator selection. Gate construction, hinge condition, installation geometry, wind loading, hardware, expected usage, and other site conditions should also be evaluated.
Is the LA400DCS 24VDC?
Yes. The LA400 platform uses a 24VDC continuous-duty motor architecture. LiftMaster's LA400 product documentation identifies the system as a 24VDC residential linear actuator.
Is the LA400DCS residential or commercial?
The LA400 platform is primarily designed as a residential linear actuator system. LiftMaster currently categorizes the LA400UL as a 24VDC Residential Linear Actuator.
For heavier or more demanding residential/light-commercial swing gate applications, the LA500 platform may be more appropriate.
Can I replace only the secondary actuator on my LA400?
Yes, when the secondary actuator is the component requiring replacement and the remaining compatible LA400 equipment remains serviceable.
The gate operator should be properly diagnosed before replacement to verify that the actuator itself is responsible for the problem.
Does the LA400DCS include the primary actuator?
No. The primary actuator is separate.
The LA400DCS is specifically intended to operate the secondary gate leaf in a compatible dual LA400 system.
Does the LA400DCS include a control box?
No. This listing is for the LA400DCS secondary actuator arm only.
The primary LA400 system provides the compatible control architecture required for operation.
Can the LA400 be used for a dual swing gate?
Yes. LiftMaster specifically identifies LA400PKGU + LA400DCS as a dual-gate configuration.
The LA400 platform also supports wireless dual-gate communication, which can help avoid running communication conduit across a driveway in appropriately configured installations.
Can the LA400 platform operate on solar power?
Yes. LiftMaster describes the LA400 platform as solar-ready and lists solar power as an option for the system.
Solar-system sizing depends on geographic location, available sunlight, gate usage, battery capacity, accessory loads, and other site-specific conditions.
Does replacing the LA400DCS change the required gate safety equipment?
No. Replacing the actuator does not remove or reduce the gate system's entrapment-protection requirements.
Installers should follow current LiftMaster installation instructions, applicable UL 325 requirements, local codes, and other applicable standards when servicing or modifying an automatic gate system.
