UL 325 Entrapment Protection Requirements

A slide gate entrapment zone exists if, at any point during travel, the gap between the gate and any opposing fixed edge or surface, such as posts, walls, pillars, columns, or the operator itself, is less than 16 inches (406 mm) in a location up to 6 feet above grade.

A minimum of two independent monitored entrapment protection devices is required at each entrapment zone. A slide gate operator will only operate with a minimum of two independent monitored devices installed in each direction: two in the open direction and two in the closed direction. Devices are independent only if they are different types (photoelectric sensors, edge device, inherent protection device). This operator includes one inherent (built-in) device; the installer must add the others. Acceptable device types are inherent, LiftMaster monitored external photoelectric sensors, and LiftMaster monitored external edge sensors.

Gate systems are made up of many component parts, and the operator is only one of them. Installers must account for the hazards of each individual application. For a slide gate, all openings must be guarded or screened from the bottom of the gate to a minimum of 6 feet above the ground so a 2-1/4 inch diameter sphere cannot pass through, both in the gate and in the portion of the adjacent fence that the gate covers in the open position. Exposed pinch points must be eliminated or guarded, including guards for exposed rollers.

Pedestrians must always be provided a separate access opening located so they never come in contact with the vehicular gate during its travel. Permanently mounted access controls must sit at least 6 feet from any moving gate part. A minimum of two warning signs must be installed so each is visible from the side of the gate where it is mounted. Contact sensors should be located where the risk of entrapment exists, such as the leading edge, trailing edge, and post mounted both inside and outside of the gate.

Dealers and installers must make sure the whole system meets UL 325 and ASTM F2200, demonstrate the safety features and manual disconnect to the owner, leave all literature with the end user, and explain that the entrapment protection devices must be re-tested monthly. End users should never attempt to repair the gate system, should routinely check all functions, should discontinue use if safety systems operate improperly or the gate is difficult to move, and should keep warning signs displayed on both sides of the gate.

Gates should be installed according to ASTM F2200. Gates must not fall over more than 45 degrees from vertical if detached from their hardware, must have smooth bottom edges with no protrusions exceeding 0.5 inches, and must not move under gravity alone if the operator is disconnected.

For Class I, II, and III horizontal slide gates: all weight-bearing exposed rollers 8 feet or less above grade must be guarded or covered; all openings must be guarded or screened to prevent a 2-1/4 inch sphere from passing through; the gap between a fixed object nearest the roadway (such as a gate support post) and the gate frame in the fully open or fully closed position must not exceed 2-1/4 inches (other fixed objects more than 16 inches from the gate frame are exempt); positive stops are required at the fully open and fully closed positions; and the gate must have enough lateral stability to enter a receiver guide. Class IV slide gates require guarded rollers and positive stops.

The carton includes the operator, cover, a LiftMaster Monitored Retro-Reflective Photoelectric Sensor kit (Model LMRRUL), a 5 ft edge sensor kit, two warning signs and a warranty card, one 12 Vdc 7AH battery, and the installation manual. Not shown: documentation packet, #41 chain (30 feet), and the eye bolt kit.

Operator Specifications

Accessory Power: 12 Vdc, 500mA max. Solar Power Max: 12 Vdc at 30 watts max. Maximum Gate Weight: 800 lbs. Gate Travel Distance: 25 feet minimum and 50 feet maximum as listed in the specifications (see the note on limits in the Adjustment section). Maximum Gate Travel Speed: 12 inches/second. Maximum Daily Cycle Rate: 120 cycles/day. Maximum Duty Cycle: Continuous. Operating Temperature: -20°C to 60°C (-4°F to 140°F) without heater, -40°C to 60°C (-40°F to 140°F) with optional heater. Expansion Board: Optional.

External entrapment protection device inputs: the main board accepts up to 2 close entrapment protection devices and 1 open entrapment protection device. An optional expansion board adds up to 3 devices configurable to either direction, plus up to 8 edge sensors when using wireless edge sensor kit models LMWEKITU and LMWETXU.

The manual includes a mounting footprint drawing for the operator and its four anchor points; see the official PDF for the dimensioned drawing.

Check national and local building codes before installation. Trench and install conduit before pouring the concrete pad or setting the post; contact underground utility locating companies first, and use UL-approved conduit. Consider the operator placement before installing the pad or post. Vehicle loops, while not required, are recommended for vehicles 14 feet or longer to keep the gate open while a vehicle blocks its path.

Safety catch rollers: install catch rollers with safety covers on the side of a post or wall, with a minimal distance of half an inch between the rollers and the gate. Do not use a gate catch post. Because the coasting distance can change with temperature, a catch post in front of the gate's path may cause the gate to hit the post in certain conditions.

CAUTION: To avoid damaging gas, power, or other underground utility lines, contact underground utility locating companies BEFORE digging more than 18 inches deep. Always wear protective gloves and eye protection when changing the battery or working around the battery compartment.

Two layouts are available. In a standard installation, the operator sits near the front roller of the gate. In a rear installation, the operator sits near the back of the gate in the open position. For either layout: lay out the concrete pad, install the electrical conduit, and pour a reinforced concrete pad (reinforced concrete is required). The pad should sit 6 inches above ground and below the frost line; check all national and local codes. Follow the layout drawing in the official PDF for exact pad dimensions and placement relative to the gate and conduit.

Attach the operator to the concrete pad with appropriate fasteners; the manual shows four concrete anchors, 1/2 inch by 3-1/2 inch. The operator should be near the front roller of the gate or near the back of the gate (in the open position). The space between the gate and the output sprocket must be a minimum of 4 inches.

DO NOT run the operator until instructed.

Standard Installation

1. Manually open the gate and line up the front bracket so the chain will be level with the idler pulley and parallel to the ground, then weld the front bracket in this position. 2. Manually close the gate and line up the rear bracket the same way, then weld it in place. 3. Route the chain through the operator. 4. Connect the chain to the brackets using the eye bolt hardware; the chain should not be too tight or have excessive slack.

Rear Installation

This layout requires two extra idler pulleys, and all exposed pinch points must be guarded. 1. Move the back pulley to the bottom hole in the operator. 2. Manually close the gate and align the bottom bracket so the chain is level with the bottom idler pulley and parallel to the ground, then weld it. 3. Align the top bracket so the chain is level with the top idler pulley and parallel to the ground, then weld it. 4. Route the chain through the operator. 5. Connect the chain to the brackets with the eye bolt hardware. The idler pulley MUST have a safety cover.

NOTE: The chain should have no more than 1 inch (2.5 cm) of sag for every 10 feet (3 m) of chain length.

WARNING: ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. Entrapment protection devices MUST be located to protect in BOTH the open and close gate cycles, between the moving gate and RIGID objects such as posts, walls, pillars, columns, or the operator itself.

1. Install entrapment protection devices for ALL entrapment zones. The operator has one inherent device built in, so the installer MUST provide one additional device for each entrapment zone. 2. The operator will NOT run unless a minimum of two external devices are connected: one in the open direction and one in the closed direction. 3. Test ALL entrapment protection devices after installing the operator, and test the inherent protection using the Obstruction Test. Any gap larger than 2-1/4 inches between the gate and fixed objects must be protected; install edge sensors where the gap between the post and the gate creates an entrapment zone.

The control board has dedicated inputs: CLOSE EYES/INTERRUPT for photoelectric sensors in the close direction, CLOSE EDGE for edge sensors in the close direction, and OPEN EYES/EDGE for sensors in the open direction. The optional expansion board adds EYE ONLY and EYE/EDGE inputs that can be switched to either direction, plus a wireless edge input (only one wireless edge receiver per operator, with up to 4 LMWETXU transmitters programmed to it). Only one monitored device may be wired to each input.

Install the earth ground rod within 3 feet of the operator using a single, whole piece of wire, never spliced. Improper grounding reduces remote control range and increases susceptibility to lightning and surge damage.

The operator can be wired for 120 Vac or a solar panel (not provided). The battery is charged in the circuit by the integrated transformer. For dual gate applications, power must be connected to each operator, and main power and control wiring must always run in separate conduits. All control wiring to Class 2 circuits must be Power-Limited Circuit Cable Type CL2, CL2P, CL2R, or CL2X or better.

Power wiring: 1. Turn off AC power at the main breaker. 2. Run the AC power wires to the operator. 3. Unplug the transformer. 4. Remove the junction box cover. 5. Run the AC wires through the knockout in the bottom of the electrical box. 6. Connect the green wire to the earth ground rod and AC ground. 7. Connect the white wire to NEUTRAL. 8. Connect the black wire to HOT. 9. Replace the cover without pinching wires. 10. Plug in the transformer. 11. Turn ON AC power.

Maximum wire length. Use copper conductors ONLY.

The operator requires one 7AH battery (provided) or one 33AH battery. 7AH battery: 1. Unplug the transformer. 2. Unplug the J15 plug labeled BATT from the control board, which disconnects AC/DC power to the board. 3. Connect the red J15 wire to the positive (+) battery terminal. 4. Connect the black J15 wire to the negative (-) terminal. 5. Plug J15 back into the control board (a small spark is normal). 6. Plug in the transformer.

33AH battery: this application requires the 33AH wire harness (Model K94-37236). Unplug the transformer, unplug the J15 plug and discard it along with its harness, connect the new harness's red (+) and black (-) wires to the new J15 plug wires and to the battery terminals as shown in the manual, plug the new J15 plug into the control board, and plug in the transformer.

Dual gate communication is either wired or wireless, never both at once. Wired setups keep a longer battery standby time than wireless setups.

Wireless: choose a primary operator and program all wireless accessories to it. Press and release LEARN on the primary (green XMITTER LED lights, 180 second timeout), press LEARN again (yellow NETWORK LED lights), then press the OPEN test button to assign it as network primary. On the second operator, press LEARN twice, then press the CLOSE test button to assign it as network second. Both operators beep and the NETWORK LEDs turn off when successful. To deactivate, press LEARN twice, then hold LEARN for 5 seconds on each operator. Erasing the wireless feature also erases any learned transmitters and keypads.

Wired: disconnect all power and unplug the J15 plug, trench across the driveway (use PVC conduit), and connect shielded twisted pair cable to the Com Link terminals on each control board (Com Link A to A, B to B), grounding the shield to the chassis of one operator. 22 AWG cable is rated up to 200 feet; 18 AWG for 200 to 1,000 feet; wire must be rated 30 Volt minimum.

Bipart delay and synchronized close: for slide gate applications the BIPART DELAY function is not applicable and should be set to OFF. The switch is also used for SYNCHRONIZED CLOSE: when one gate travels a longer distance than the other, set the switch to ON for both operators so the gates close together.

Before installing the cover, set the limits and force per the Adjustment section. Slide the cover over the operator, align the hole in the cover with the threaded hole in the operator's chassis, and secure the cover with the provided 5/16-18 screw.

Warning signs: installers MUST install the UL required warning signs in plain view on both sides of each gate, using the fastening holes in each corner. The basic installation is now complete.

Never increase force beyond the minimum needed to move the gate, and never use force to compensate for a binding or sticking gate. After any adjustment to force or travel limits, retest the safety reversal system: the gate must reverse on contact with an object. The TEST buttons will not work until the limits are set and the required entrapment protection devices are installed.

For dual gate applications the limits must be set for each operator, with the gate attached to the operator first. For slide gate applications the open limit and close limit MUST be set at least four feet apart. Note that the manual's specifications table lists a 25 foot minimum gate travel distance, so confirm the correct minimum for your gate against the official PDF. If you make a mistake, press the reset button to start over.

1. Press and release SET OPEN and SET CLOSE together to enter limit setting mode. 2. Press and hold a MOVE GATE button to move the gate to the open or close limit. 3. Press and release SET CLOSE or SET OPEN for the limit being set. 4. Press and hold a MOVE GATE button to move the gate to the other limit. 5. Press and release the matching SET button. 6. Cycle the gate open and close; this sets the force automatically. The operator exits limit setting mode on its own once the limits are set.

The limit LEDs show the status: both off means limits are set (normal mode); both blinking means limits are not set; SET OPEN blinking with SET CLOSE on means the open limit is not set; SET OPEN on with SET CLOSE blinking means the close limit is not set.

The REVERSAL FORCE dial is set to minimum at the factory and is used to fine-tune force for wind or environmental changes. The force should be high enough that the gate will not reverse by itself or cause nuisance interruptions, but low enough to prevent serious injury. If the gate stops or reverses before reaching a limit, turn the dial slightly clockwise. After both limits are set, one limit can be adjusted independently by repeating steps 1 to 3 of the limit procedure.

Obstruction test: 1. Open and close the gate with the TEST buttons and confirm it stops at the correct limits. 2. Place an object in the gate's path, or obstruct it by hand, without triggering any external entrapment device. 3. Run the gate in the close direction; it should stop and reverse on contact. If it does not, turn the force dial slightly counterclockwise. 4. Repeat the test in the open direction. Test the operator after any adjustment.

Up to 50 Security+ 2.0® remotes or KPW250 keypads, plus 2 keyless entries, can be stored in memory. To program a remote, press and release the LEARN button (the green XMITTER LED lights), then press the remote button to program within 30 seconds. Three programming options exist: single button as open only, single button as open/close/stop, or three separate buttons for open, close, and stop. If you install an 86LM antenna extension, do not straighten the antenna.

You can also enter programming mode with an external reset button or 3-button control station: make sure the gate is closed, give the operator an OPEN command, then within 30 seconds at the open limit press and release the RESET/STOP button twice.

The LiftMaster Internet Gateway pairs through an online account at myliftmaster.com after connecting it to a router and powering it on, then pressing LEARN twice on the primary operator (or using the reset button sequence: with the gate closed, give an OPEN command, then press the reset button three times within 30 seconds at the open limit).

To erase all remote codes: press LEARN, then press and hold it again for about 6 seconds until the XMITTER LED flashes. To erase limits: hold SET OPEN and SET CLOSE together for 5 seconds until both LEDs blink rapidly and the operator beeps. To remove and erase monitored entrapment protection devices: disconnect the device wires, press SET OPEN and SET CLOSE together to turn both LEDs on, then press them together again to exit.

Constant Pressure Override (CPO) is for use with KPW5 and KPW250 keypads. It temporarily bypasses a faulted entrapment protection device: enter a valid 4-digit PIN, then press and hold # for 5 seconds and keep holding to keep the gate moving. Use it only in direct line of sight with no obstructions. The Gate Hold Open feature disables the Timer-to-Close and keeps the gate at the open limit using the same PIN entry while the timer is running; re-enter the PIN or activate a hard input or programmed remote to restart.

The control board includes SET OPEN and SET CLOSE buttons for limits, MOVE GATE buttons for jogging the gate during setup, a BATT FAIL option switch (critically low battery is less than 11.5 V), a BIPART DELAY switch for dual gates, a LEARN button for remotes and the wireless network, a TIMER-TO-CLOSE dial (0 to 180 seconds, 0 is off), a REVERSAL FORCE dial, TEST buttons for open/stop/close, status LEDs, and a diagnostics display showing the operator type ("SL12" for the RSL12UL), firmware version, and error codes.

The BACKDRIVE switch controls what happens if AC and battery power are both lost: set to MANUAL, the gate can be pushed open or closed by hand; set to SECURE, the gate is difficult to push open or closed.

Reset switch: located on the front of the operator. Toggling it stops a moving gate like a stop button without needing a reset, disables the gate in its present position, and energizes the solenoid lock and disables the maglock for two minutes.

Manual disconnect: press the reset switch to the off position "O" to allow the gate to be opened and closed manually. On a dual gate application, do this on both operators. Return the switch to the on position "I" to resume normal operation. Use the manual disconnect only when the gate is not moving.

Operator alarm: if a contact sensor detects an obstruction twice consecutively, or if the inherent force sensor detects the following twice consecutively, the alarm sounds for up to 5 minutes and the operator must be reset: the gate hitting an obstruction, the gate not meeting specifications, debris on the gate track such as mud, rocks, or dirt, one or more broken axles or wheels, or a gate wheel off the gate rail. Remove obstructions or repair the gate, then press the reset switch to silence the alarm. Three beeps with a command indicate a low battery.

Single button remote: with the gate closed, one press opens it, a second press during the open cycle stops it, and a third press closes it. With the gate open, a press closes it; if pressed while closing, the gate stops and the next press opens it.

All control wiring to Class 2 circuits must be Power-Limited Circuit Cable Type CL2, CL2P, CL2R, or CL2X or better. None of the following inputs may be used as entrapment protection.

The EXIT input is a soft open command for exit probes, telephone entry, or exit loop detectors. SHADOW holds the gate open at the limit when a loop is positioned under the gate and is only active at the OPEN limit. INTERRUPT holds the gate open and reverses a closing gate when a loop sits outside the gate, and activates quick close and anti-tailgate features when enabled on the expansion board.

The maglock output (N.C. and COM) is a normally-closed relay contact that activates before and during motor movement. The three-button control station wires OPEN, CLOSE, and STOP with a common, each overriding external safeties within line of sight. The Fire Department input acts as a hard open that overrides external safeties. Accessory power provides 12 Vdc at 500mA max, either switched (on during motion and while the Timer-to-Close is active, off 5 seconds after motion) or unswitched (always on).

WARNING: ALL maintenance MUST be performed by a Trained Gate Systems Technician. Disconnect all power (AC, solar, battery) before servicing; the AC power switch only turns off AC power to the control board and does NOT turn off battery power. Use ONLY LiftMaster part 29-NP712 for replacement batteries.

Notes: limits may have to be reset after any major drive chain adjustment. If lubricating the chain, use only lithium spray. Never use grease or silicone spray. Verify with a digital voltmeter that incoming voltage is within ten percent of the operator's rating.

Batteries: they degrade with temperature and use, and do not perform well in extreme cold. Replace them every 3 years with LiftMaster part 29-NP712 only, and dispose of them properly because they contain lead. The operator comes with one 7AH battery; one 33AH battery (A12330SGLPK) with the 33AH battery harness (K94-37236) may be used in its place.

Drive train: the chain will stretch over time. To tighten it, adjust either of the two chain eye bolts, keeping sag to no more than 1 inch for every 10 feet of chain.

To view codes, press and hold STOP, then CLOSE, then OPEN until "Er" shows on the display. The display shows the code sequence number (01 is the most recent) followed by the code itself. Press OPEN to scroll to the most recent code and CLOSE to scroll toward the oldest (up to 20 saved). Press and release STOP to exit; the display also times out after two minutes. To reset the code history, press and hold STOP for six seconds until "Er" then "CL" alternate, then release. When cycling power to the control board, unplug the J15 plug.

Control board status LEDs show input power, battery charging, timer state, gate motion (blink patterns show single or double entrapment), battery low, and accessory overload. Input LEDs for SBC, Fire Dept, Exit, Shadow, Close Eyes/Interrupt, Close Edge, Open Eyes/Edge, and Lock show off (inactive), on (active), or blinking (active on the other operator).

For dual gate installations, set all accessories and board configurations on the primary operator. The manual's Dual Gate Settings table lists: Timer-to-Close set on the primary and OFF on the secondary; remote controls 1 to 50 programmed to the primary and 51 to 100 to the secondary; and the Internet Gateway and Garage and Gate Monitor programmed to the primary. The same table lists Bi-Part Delay ON for the primary and OFF for the secondary, with Synchronized Close ON for both, but Step 7 states that Bipart Delay does not apply to slide gates, so confirm that switch against Step 7 for your site.

Solar panels are not provided. Requirements: a minimum of one and a maximum of three 10W solar panels (Model SP10W12V) in parallel, the battery harness (Model K94-37236), and one 7AH battery or one 33AH battery. A heater cannot be used with a solar application. Solar installations are not supported in northern climates or where there are long periods of heavy fog, lake effect snow, or rain. Zone 1 (6 hours of sunlight per day) is ideal; Zone 2 (4 hours) is recommended; Zone 3 (2 hours) depends on the operator and panel placement.

Standby current draw at 12V: control board with no radios, 4.2 mA; programmed LiftMaster remotes, +1.5 mA; myQ device or wireless dual gate, +3.9 mA; expansion board, +18.5 mA; each plug-in loop detector, +6.6 mA (up to 3). Photoelectric sensor heaters (LMRRUL, LMTBUL) are not recommended in solar applications. Cycles per day depend on zone, panel wattage, and battery size: at a 6 mA draw in Zone 1, a single 10W panel supports roughly 33 cycles per day with a 7AH battery, while the 20W and 30W setups reach the 50 cycles per day shown at the top of the manual's table. All figures are estimates.

Position and installation: mount panels facing due south with the provided angle bracket, clear of shade from buildings and trees for a 180-degree arc east to west. If the panel is not casting a shadow, the battery is not charging. To optimize for winter, tilt the panel up to 15 degrees more vertical. Position the bracket, mark and drill holes, secure the panel to the bracket with the hex bolts, nuts, and washers, then secure the bracket to the mounting surface with the lag screws.

Maximum solar wire length. Chart assumes copper wire, 65°C, 5% drop, 30V nominal.

Wiring: one 7AH battery, two 7AH batteries in parallel (with red and black jumper wires and a fuse), or one 33AH battery connect to the BATT DC POWER input on the control board. Solar panels wire in parallel: a 10W application uses one panel, a 20W application uses two 10W panels, and a 30W application uses three 10W panels.

Requires a 3-button remote programmed for OPEN, CLOSE, and STOP. With the gate closed, press SET OPEN and SET CLOSE together to enter limit setting mode, then jog the gate to the open position using the remote, press STOP, and press OPEN again to set the open limit. Jog the gate to the close position, press STOP, and press CLOSE again to set the close limit. Cycle the gate to set the force, then perform the obstruction test. The close limit or open limit can also be reset on its own using the same entry sequence.

The wiring diagram maps the control board terminals, the plug-in transformer and AC input, the 12V battery, optional solar panels, photoelectric and edge sensor terminals, the optional maglock, the reset switch, the alarm, and the antenna. See the official PDF for the complete schematic.

LiftMaster warrants this product against defects in materials and workmanship for 3 years from the date of purchase, contingent on following the installation, operation, maintenance, and testing instructions in this manual. The warranty does not cover gate or gate hardware issues, damage from improper installation or care, labor for reinstalling repaired units, or battery replacement. Call 1-800-528-2806 for warranty service before dismantling the product.

LiftMaster provides a UL 325 and ASTM F2200 Site Planning Safety Checklist for dealers, installers, and customers to sign at installation. Slide gate checks include: roller covers on weight-bearing exposed rollers 8 feet or less above grade; meshing up to 6 feet above grade if pickets are spaced 2-1/4 inches or more apart; a gap between the gate and fence post of less than 2-1/4 inches, with any larger gap protected by a safety device; positive stops at both the fully open and fully closed positions; and receiver guides recessed behind the receiver post when they are less than 8 feet. General checks cover smooth bottom edges, access controls at least 6 feet from the gate, barbed tape and wire heights, a separate pedestrian gate, and a gate that does not move on its own when disconnected.

Every entrapment zone needs a minimum of two independent entrapment protection devices, and a slide gate operator will only operate with two independent monitored devices in each direction. Take a photograph of the completed installation for your records and place warning signs on both sides of the gate.
