What makes a Maximum Controls operator different

• Brushless DC motor. Every Maximum Controls gate operator uses a brushless DC motor with a built in Hall effect encoder, rated at 6,000,000 gate cycles and backed by a 5 year warranty. With no brushes to wear, Maximum Controls lists it as low maintenance and very quiet.
• Direct gear drive. No chains, belts or pulleys inside the operator, with adaptive DSP motion control for a smooth start and stop.
• Battery backup as standard. Every operator comes with battery backup, good for 85 to 500 cycles depending on gate size and use.
• Built for weather. Rated to run from 4°F below zero to 165°F, battery included, without a heater, and lightning protection up to 20,000 volts and 10,000 amps on the inputs and outputs.
• A black box. The operator logs its most recent 8,000 events, which a technician downloads to a USB drive to see what the gate did and when.
• Made in the USA, by a company in business since 2009.

Maximum Controls makes pad mount swing operators (the Megatron series), linear actuator arms for swing gates (Ultra Arm, Super Arm 1300 and 2300) and slide gate operators (Max PRO series, MXG series and the Rhino). The Megatron 1400 PRO handles a 1,400 lb gate up to 15 ft; the largest slide operator, the Rhino 5500, handles 5,500 lb.

From Maximum Controls’ 2025 product catalog and product pages (max.us.com), checked November 2026. Maximum Controls lists its pad mount operators for high traffic commercial use and its arms for residential and commercial use. “FS” models are fail safe: Maximum Controls describes them as back drivable by hand when AC power is lost or the battery runs down.

Which Maximum Controls operator fits your gate?

• A residential swing gate: usually an Ultra Arm or Super Arm, mounted between the post and the gate, one per leaf on a dual gate.
• A heavy, tall or busy swing gate: a Megatron on a pad beside the gate, sized by the gate’s weight and length.
• A slide gate: a PRO or MXG operator sized by weight and length; the Rhino for very heavy industrial gates.
• Usage class matters. UL 325 Class I is a home; Class II is a community, apartment or business open to the public; Classes III and IV are industrial and guarded sites. Check the class before choosing a model.

Gate projects are quoted per project. We look at the gate, its hinges or track and the power at the site, then give you a free estimate and a firm price before any work begins.

Maximum Controls’ warranty

The warranty runs from the date of manufacture (the first 8 digits of the serial number), or from the dealer’s purchase date with a receipt. Maximum Controls does not cover damage from a vehicle strike, water, fire, lightning, extreme wind, vandalism, negligence such as leaving the cover off in the rain, a gate too heavy for the operator, or unauthorized repairs; for the arms, also damage from a gate left swinging freely in manual release. Products bought online from unauthorized sellers are not covered.

• Max Cloud App with the Max Cell Hub. The Cell Hub connects the operator over cellular data. From the app you can open or close the gate from anywhere, add administrators, give users time based access, issue temporary guest passes, set automatic open and close times, and read the gate’s event log. Maximum Controls says it supports more than 10,000 virtual transmitters.
• Keypads and card readers. The Max Cell Hub Keypad and the Max Wiegand Converter take 26 bit card readers, radio receivers and RFID tags, and keycodes, cards and remotes are programmed in the app with optional time limits.
• Aeromax 200 long range wireless intercom. An outdoor stainless steel call station that talks to indoor Aeromax 100 and 100S units by 900 MHz radio, up to 4,000 ft in direct line of sight, with hands free, full duplex audio. Maximum Controls says it works with all electric gate openers, has two relays for two access points, can run on solar power, works from 40°F below zero to 158°F and has a 2 year warranty. The Aeromax 200K adds a keypad.
• Wireless Edge 900. A wireless safety edge for Maximum Controls operators only: 915 MHz, range up to 200 ft, 100 millisecond response, battery life up to 2 years, and it reports to the operator’s log and the Max app. 2 year warranty.
• Other wireless links. Maximum Controls also makes the Max Wireless Relay Pair, Max Wireless Push Button and Max Wireless RS-485 Pair.

For video, we also install DoorBird video intercoms with gate operators, so you can see and talk to visitors at the gate from your phone.

All of Maximum Controls’ PRO series swing and slide operators are solar ready, and all of its linear actuator arms can run on solar through the Max Solar Control Box. Maximum Controls lists its solar ready operators, Solar Pack and Solar Control Box as UL 325 and UL 1741 compliant.

• Max Solar Pack: fits under the PRO series swing and slide operators (the Megatron 1400 PRO uses a separate install box). It takes up to a 200 W solar panel and has a 24 V, 10 A solar regulator and a 24 V, 36 amp hour AGM battery bank.
• Max Solar Control Box: runs the arms, with a 24 V, 10 A regulator and a 24 V, 18 amp hour AGM battery bank.
• The arms have a solar mode switch that cuts their idle draw to 5 milliamps.

Maximum Controls operators are UL 325 compliant for Class I to IV gates and have inherent entrapment protection built in. Like every automatic gate under UL 325, they also need external monitored photo eyes or safety edges at each place a person could be caught. Maximum Controls’ manual says at least one entrapment protection device must be installed or the operator will not function.

• Two kinds of protection. The built in sensor (Type A) plus monitored photo eyes (Type B1) or safety edges (Type B2). The same type of device cannot be used for both means of protection.
• Both directions. Sensors go in the opening and closing direction wherever there is an entrapment area or pinch point.
• Photo eyes are powered by the operator. A photo eye must be powered from the operator’s 12 V DC output, or the operator cannot monitor it.
• Maximum Controls safety devices include the Max Edge 1 and Max Mini Edge for slide gates, the Wireless Edge 900 and the EMX IRB MON photo eye.
• Controls and signs. An opening device must be at least 6 feet from all moving parts of the gate, in sight of the gate, high enough to keep it out of reach of small children, and never reachable through the gate. At least two warning signs go up, one on each side.

From the safety and entrapment protection sections of the Max Ultra Arm V.3 manual and Maximum Controls’ UL 325 2018 pages (max.us.com), checked November 2026.

When a Maximum Controls gate will not open or close, the LEDs on its control board usually show why: an entrapment sensor that is blocked or out of line, an active loop or open input, or the battery backup running low. Clear the gate path and the photo eyes first; for anything inside the control box, call a technician.

Maximum Controls’ quarterly checklist

Maximum Controls publishes a quarterly checklist for its swing and slide operators. It is a technician’s service visit:

• Clear vegetation around the operator and gate, and blow out debris
• Check the oil level on the side of the gearbox
• Swing gates: check the arm is not binding and grease the hinges. Slide gates: check the wheels and guide rollers
• Check voltage and amp draw in program mode, and all inputs
• Test the UL sensor and the safety edges
• Test the battery backup and check the battery voltage while the gate is moving

Between visits, test the photo eyes and edges every month as Maximum Controls’ safety rules say, and stop using the gate if it does not reverse or stop.

Call us for a new Maximum Controls swing or slide gate operator, a Megatron, Ultra Arm or Super Arm, solar power, photo eyes and wireless edges, Aeromax intercoms, Max app setup, or a repair on a gate that will not open or close.
