LiftMaster MATDCBB3 DC Barrier Gate Operator

High-Traffic Barrier Automation with Battery Backup and Aluminum Tower Cabinet

The LiftMaster MATDCBB3 DC Barrier Gate Operator is a high-traffic vehicular barrier system designed for commercial, industrial, parking, and controlled-access entrances. The MAT tower configuration combines a full aluminum cabinet with a 24 VDC continuous-duty motor, battery backup, magnetic limit sensing, and fast 2.5-second opening and closing for entrances that process frequent vehicle traffic.

Rated for up to 6,000 cycles per day, the MATDCBB3 uses a 1/2 HP equivalent DC motor and 60:1 wormgear reducer operating in a synthetic oil bath. Smooth start and stop, dynamic motor braking, magnetic limits, and industrial surge suppression are designed for repeatable operation in high-cycle environments.

Two 12V 7Ah batteries provide backup operation during AC power loss. The controller also supports Security+ 2.0 access control, Multi-Vehicle Memory, Anti-Tailgate, automatic closing, and SAMS integration with compatible LiftMaster slide or swing gate operators.

Barrier arms are sold separately, allowing the operator to be matched with straight, articulating, LED, aluminum, or PVC arm configurations from approximately 9 to 17 ft.

Conclusion

The LiftMaster MATDCBB3 is built for vehicle entrances where fast barrier movement, high daily cycle capacity, battery backup, and commercial access-control integration are priorities. The full aluminum tower cabinet distinguishes the MAT configuration from the pedestal-style MA operator while retaining the same high-traffic DC barrier platform.

Select the barrier arm separately according to the required lane width and installation layout. Longer 17 ft arm configurations require the specified LiftMaster counterweight, and SAMS installations require the appropriate optional relay equipment when coordinating the barrier with a slide or swing gate operator.
