LiftMaster Mega Arm Barrier Gate Operator
The MegaArm and MegaArm Tower are DC-powered additions to the LiftMaster family of gate operators. Designed with a 24 VDC (1/2HP equivalent) motor, these models provide exceptional starting torque and continuous operation, making them ideal for most applications. Constructed with an aluminum alloy chassis, they are corrosion resistant and light enough for one person to carry and install. The heavy-duty motor supports 6,000 cycles per day with an operator speed of 2.5 seconds to open or close.Built-in battery backup provides seamless operation of the gate operator and all DC control and sensing devices in the vent of a power loss.
FEATURES:
• Built-in Radio Receiver - LM312hm
• Aluminum Alloy Chassis - All rust proof aluminum construction with powder coat baked on enamel
• Built-in Battery Backup - 24 VDC backup power with regulated 24VDC for accessories
• Soft Start/Stop - in open and close travel motions
• DC Operator System - High torque 24 volt Permanent Magnet DC motor
• Continuous duty operation for all applications (even during power failures)
• Reversible arm direction for Right or Left-Handed Operation
• Breakaway Arm - Break away mounting design for the 12 - 15 ft. X 3" tubular aluminum arm
• Control Inputs - Full service controller with eight inputs and LED indicators for loops, card reader, radio, etc...
• Inherent Obstruction Sensing - Instant Reverse Device (IRD) monitor senses obstructions during open and close
• Led Indicators - LED diagnostic center for easy on-site trouble shooting
• Dual Gate Operation - Each unit configurable as master or slave operator
• Dynamic Motor Braking - to preserve arm positioning
• Magnetic Sensors - No limit switches to fail-uses magnetic (Hall Effect) sensors to monitor arm position
• Timer to Close - adjustable from 1-33 seconds with on/off selection
• 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
• Molded Polyethylene UV stabilized cover never needs wax or paint
• 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
• Maximum Run Timer for motor (MRT) with anti-tamper protection in closing direction
• Safe 24 VDC low voltage motor and control wiring
• Open architecture PCB with space for OVERDRIVE CPU for future expanded options
• 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
• Anti-tail gate alarm-K1 relay can be programmed to trigger a warning device when tail gating is sensed on the close loop
