LiftMaster CSW24UL Commercial Swing Gate Operator

Battery-Backed DC Swing Gate Automation for High-Traffic Entrances

The LiftMaster CSW24UL Commercial Swing Gate Operator is a 24 VDC continuous-duty system designed for high-traffic residential, commercial, industrial, and restricted-access vehicular entrances. Its heavy-duty gear-driven design supports gates up to 1,600 lb at 8 ft, 1,200 lb at 12 ft, 800 lb at 16 ft, or 600 lb at 18 ft, allowing the operator to accommodate a wide range of large swing gates.

Unlike an AC-only commercial operator, the CSW24UL runs from a 24 VDC system with integrated battery backup. Two 7Ah batteries are included, providing continued gate operation during an AC power outage. The operator accepts 120 or 240 VAC input and is also solar capable for installations where off-grid or supplemental solar power is preferred.

The CSW24UL includes myQ technology for remote monitoring and gate control when paired with compatible LiftMaster connectivity equipment. Security+ 2.0 wireless access, electronic limits, soft start and soft stop, inherent obstruction sensing, wireless dual-gate communication, programmable safety functions, and an included expansion board provide the control flexibility expected in commercial gate installations.

Conclusion

The LiftMaster CSW24UL combines the heavy-duty construction of a commercial swing gate operator with the advantages of DC operation, battery backup, solar capability, and myQ connectivity. It is well suited to gated communities, commercial properties, industrial entrances, and other high-use locations where continued operation during a power outage is important.

Gate capacity should be selected using both gate length and weight, rather than treating the 1,600 lb and 18 ft maximums as simultaneous ratings. The included LMRRUL provides monitored external entrapment protection, but each installation must still be evaluated for additional monitored devices required by the gate layout and identified entrapment zones.
