LiftMaster CSW200501UL 1/2 HP Swing Gate Operator

High-Traffic Commercial Swing Gate Automation with Gear-Driven Power

The LiftMaster CSW200501UL is a 1/2 HP commercial swing gate operator designed for high-traffic residential, commercial, industrial, and restricted-access vehicular entrances. Its continuous-duty AC motor and heavy-duty gear-driven transmission are built for applications where frequent gate operation and substantial gate weight require more capacity than a residential linear actuator.

Gate capacity depends on the length of the gate leaf. The 1/2 HP CSW200501UL is rated for 1,600 lb at 8 ft, 1,200 lb at 12 ft, 800 lb at 16 ft, and 600 lb at 18 ft. Two commercial oil-bath gearboxes provide a 900:1 wormgear reduction, while the adjustable swing arm transfers power from the operator to the gate.

The CSW200501UL includes LiftMaster's control board and expansion board, Security+ 2.0 radio receiver, monitored safety inputs, diagnostic display, programmable auxiliary relays, and an LMRRUL monitored retro-reflective photoeye. It is also compatible with myQ-connected LiftMaster equipment for remote monitoring and access management.

What Comes with the Operator

• 1 LiftMaster CSW200501UL 1/2 HP swing gate operator
• 1 Adjustable swing gate arm assembly
• 1 Main control board
• 1 Expansion board
• 1 LMRRUL monitored retro-reflective photoeye
• 2 Operator keys
• 2 Warning signs
• Operator cover, installation hardware, and documentation

Remote controls are not included. Additional monitored photoeyes or sensing edges may be required depending on the entrapment zones present at the installation.

Installation Considerations

The CSW200501UL is typically installed on a reinforced concrete pad and secured with appropriate anchors. LiftMaster also offers optional mounting hardware for applications requiring an alternate mounting method.

Gate capacity must be evaluated using both gate length and gate weight. The 1,600 lb rating applies to an 8 ft gate, while an 18 ft gate is rated up to 600 lb. The gate must also be properly supported, level, plumb, and move freely through its full swing before automation.

The included LMRRUL provides monitored external entrapment protection, but each installation must be evaluated for all open- and close-direction entrapment zones. Additional monitored devices may be required to satisfy UL 325 installation requirements.

Conclusion

The LiftMaster CSW200501UL is designed for high-traffic swing gate installations that require continuous-duty operation, substantial gate capacity, commercial gear-driven construction, and flexible access and safety integration. Its included expansion board, monitored photoeye, loop detector provisions, programmable relays, and dual-gate capabilities make it well suited to commercial properties, gated communities, industrial facilities, and other frequently operated vehicular entrances.

For heavier or longer gates, the LiftMaster CSW200101UL 1 HP model provides the higher-capacity option within the CSW200UL family.
