All-O-Matic SL-45DC PRO Slide Gate Opener, 800 lb / 30 ft with Battery Backup

Slide gates up to 800 lb and 30 ft long. For heavier or longer gates, the SL-90DC PRO is rated to 1,600 lb and 50 ft.

It is listed for UL 325 Class I (homes) and Class II (commercial sites open to the public, such as an apartment entrance) only, and the warranty is 5 years residential with no commercial term. For Classes III–IV, industrial sites or a commercial warranty, choose the SL-90DC PRO.

Two 12V 7Ah batteries are included. All-O-Matic rates them at about 250 cycles on a 600 lb gate. A DIP switch picks fail-safe (the gate opens before the battery runs flat) or fail-secure (it stays closed), and an AUTO OPEN setting opens the gate about 40 seconds after a power loss for fire-department access.

Remove the cover, turn the AC and DC switches off and push the gate open. The planetary gearbox can be back-driven, so the SL-45DC PRO has no foot-pedal release; the pedal is on the SL-90DC and larger models.

Yes. The board has a solar input with an MPPT regulator for a 24V panel of at least 40 W and up to 80 W. With two 14Ah batteries, a receiver and two monitored sensors, All-O-Matic estimates about 20 cycles a day. The panel and larger batteries are not included, and above 80 W you need an external charge controller.

115 V (2 A) or 230 V (1 A) single phase, selected with a switch. All-O-Matic calls for a dedicated 20 A circuit in conduit and an earth ground rod.

The operator with the ALL-BLDC PRO board, two 7Ah batteries, 20 ft of #41 chain with the chain bracket, one AOM Red Eye photo eye and padlock tabs for the cover.

One AOM Red Eye photo eye is included. UL 325 requires monitored protection for every entrapment zone and the operator won't run automatically without it, so most driveways need a second eye or an edge. The board takes normally-closed or 10K-terminated devices from most brands.

No. There is no built-in receiver, so you add an external 3- or 4-wire receiver and remotes, or a keypad, wired to the board.

Yes. Two SL-45DC PRO operators pair wirelessly as primary and secondary through the PRO board, so you don't trench a cable between the posts.

Not out of the box. The board has no Wi-Fi, so phone control needs an add-on controller wired to its inputs. All-O-Matic's channel shows the Nexx NXG-200 (video above).

Yes. Padlock tabs come in the hardware bag and replace a cover bolt so you can padlock the cover. On the SL-90DC and larger models the lock kit is sold separately.

Yes. The board has a lock relay with maglock and solenoid terminals. The SL-45DC PRO has no 120 V accessory outlet, though, so the lock's transformer needs its own power.

Up to 12 inches per second, so a 16 ft opening clears in under 20 seconds. The brochure lists speed as adjustable through the LCD menu.

All-O-Matic rates it from −40° to 160°F. Batteries lose capacity in the cold, so size up the batteries at cold solar sites.

Yes. The manual shows front-mount and rear-mount layouts on a concrete pad, including how the chain attaches to the gate.

5 years residential on circuitry, motor, gearbox and workmanship, if the registration card is mailed within 30 days of purchase; otherwise 1 year on parts. Labor and shipping to and from the factory are the owner's cost.

The SL-45DC PRO is smaller (11 × 14.5 × 15.5 in, 60 lb shipped) and handles 800 lb / 30 ft, with UL Classes I–II, a push-open release and a 5-year residential warranty. The SL-90DC PRO handles 1,600 lb / 50 ft with a ½ HP motor, a foot-pedal release, Classes I–IV and 7 years residential / 5 years commercial.

Both handle 800 lb gates. The RSL12UL goes to 25 ft and has a Security+ 2.0 receiver and myQ support built in; the SL-45DC PRO goes to 30 ft, ships with two batteries instead of one, and needs an external receiver for remotes.
