Nice PRO-SW4000XLS Swing Gate Opener, 12V DC with Battery Backup

One leaf up to 20 ft long and up to 1,000 lb. Both limits apply together: the manual says the gate must not exceed 20 ft nor weigh more than 1,000 lb. Minimum gate length is 6 ft.

The master arm with a 6 ft power cable, the control box with battery box, a 12 V 7 Ah battery, an 18 VAC plug-in transformer, a 318 MHz receiver on a 10 ft cable, one remote, post and gate brackets, a closed-position stop plate, mounting hardware and two warning signs.

Yes. The PRO-SW4200XLS second arm plugs into this control box over its own 50 ft cable, and the one battery runs both arms. Buy the dual kit instead if you already know you have a double gate.

Yes, one 12 V 7 Ah sealed rechargeable battery. A second battery (RB500) can be added through the second-battery connectors in the battery box for more reserve.

The motor always runs from the 12 V battery; the transformer only keeps it charged. So the gate keeps working on battery during an outage until the charge runs down. Nice publishes no outage cycle count for this model.

Yes. Use a solar panel of at least 10 W (FM123) instead of the transformer; the manual calls for solar when the gate is more than 1,000 ft from AC power. Never connect the transformer and a panel at the same time: it damages the control board.

Yes, one GTO/Nice remote plus the 318 MHz receiver. Extra remotes are the RB741 (1-button), RB742 (2-button) and RB743 (3-button); the receiver learns them automatically.

The receiver is 318 MHz and learns GTO/Nice digital remotes, including the RB741, RB742 and RB743. Other brands aren't supported, and there's no Wi-Fi or app module for this model.

The manual lists photo beams (R4222) and contact edges as recommended, not included. DASMA's UL 325 guidance says swing operators need two means of entrapment protection in each direction that has an entrapment zone, and the built-in sensing counts as only one. Plan on at least one external sensor where an entrapment zone exists.

Out of the box it is set up for pull-to-open (the gate opens into the property). Push-to-open needs one R4KPTO bracket and a DIP-switch change on the control board.

A flat post at least 6 in square, set in concrete. Posts over 8 in need longer bolts than those supplied, wood posts need a metal backing plate, and masonry columns need anchors (not included).

Nice advises against it: wind load on a solid gate can make the operator sense an obstruction, stop and blow fuses. It's built for vinyl, aluminum, chain link, farm tube and wrought iron gates.

Up to 1,000 ft of 16-gauge, two-conductor stranded direct-burial wire (RB509, not included). The transformer is indoor-rated and needs a weatherproof cover if it plugs into an outdoor outlet.

It's rated −5 °F to 160 °F. In extreme cold the manual recommends the FM316 battery heater, which can't run on solar.

Turn the control box power switch off, then remove the hairpin clip, clevis pin and bushing at the arm's mounts and lift the arm off. Unplugging the transformer doesn't stop the operator, because it runs on battery.

24 months from purchase with proof of purchase, under Nice's DC gate operator limited warranty. Non-Nice batteries or transformers, surge or lightning damage, and removal or reinstallation labor aren't covered.

The PRO-SW3000XLS is rated 16 ft and 650 lb per leaf; the PRO-SW4000XLS is rated 20 ft and 1,000 lb. Both run on 12 V DC with the same battery and transformer. Choose the 4000XLS for long or heavy leaves, ornamental iron, or windy sites.

Nice rates it for single-family homes, farms and ranches. For an HOA, apartment or commercial entrance, choose a continuous-duty commercial operator such as the LiftMaster CSW24UL.
