The MEGA ARM by LIFTMASTER  INC. was made to be unique in the industry through innovative design and solid engineering. Its single State of the Art universal electronics control board eliminates the need for mechanical limit switches, relays and contactors. Arm position is limited by a magnet mounted on the drive shaft which is sensed by two magnetic sensors on the electronics controller. Its full service controller is capable of accepting inputs from telephone entry, loop detectors, card readers, push buttons, barcode scanners, and is equipped with multiple vehicle memory buffer. Built in regulated 24VDC backed up power provided for accessories (detectors, receivers, card readers). The standard break away arm design can allow the arm to be reused many times. Finally, its modern design and cutting edge technology will make the MEGA ARM the perfect choice for all your parking control applications.

The LIFTMASTER model MEGA-ARM barrier style parking gate operator is unique in the industry. Setting the MEGA-ARM apart are many features that make it the front runner in its class.

With standard features like:

• Built in battery backup - inherent 24 VDC backup power with regulated 24VDC for accessories.
• High torque 24 volt Permanent Magnet DC motor.
• Full service controller with eight inputs and LED indicators for loops, card reader, radio, etc...
• Continuous duty operation for all applications (even during power failures).
• Reversible arm direction for right or left handed operation.
• Instant Reverse Device (IRD) monitor senses obstructions going open and close.
• Automatic open of gate arm when power is lost if desired (With 15 sec. delay selection).
• Raise gate input memory will memorize multiple vehicles-ideal for barcode scanners & AVI.
• Ability to have arm STOP in close travel if tailgating is sensed at close loop.
• Break away mounting design for the 12 - 15 ft. X 3" tubular aluminum arm.
• All rust proof aluminum construction with powder coat baked on enamel.
• Molded Polyethylene UV stabilized cover never needs wax or paint (white or colors).
• Direct drive gear reducer eliminates many parts that might otherwise fail.
• Microprocessor (RISC) based electronics with watch dog reset timer.
• State of the art MOSFET motor drive technology, NO contactors or relays.
• Dynamic motor braking to preserve arm positioning.
• Soft start and stop in open and close travel motions.
• No limit switches to fail-uses magnetic (Hall Effect) sensors to monitor arm position.
• Maximum Run Timer for motor (MRT) with anti-tamper protection in closing direction.
• Each unit configurable as master or slave operator.
• Safe 24 VDC low voltage motor and control wiring.
• Open architecture PCB with space for OVERDRIVE CPU for future expanded options.
• LED diagnostic center for easy on-site trouble shooting.
• Closing timer adjustable from 1-33 seconds with on / off selection.
• Transorb diodes on all inputs for protection against transient voltage spikes.
• Capable of being powered by 120 VAC, 220 VAC or Solar power, standard.
• U.L. LISTED (U.S.), C-U.L. LISTED (CANADA)
• 10 year perforation warranty on cover and chassis with 2 years on electronics and mechanism.
• Interlock with memory when connected to a slide/swing gate operator, barrier will wait to raise until that unit reaches its full open position. Barrier will not raise if slide/swing gate is tampered with.
• Tail gate alarm-K1 relay can be programmed to fire when a tail gater is sensed on the close loop.
