UL325 Entrapment Protection Requirements

Definitions. ENTRAPMENT: The condition when a person is caught or held in a position that increases the risk of injury. SWING GATE ENTRAPMENT ZONE: Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8 m (6 ft.) above grade. Such locations occur if during any point in travel: a. The gap between the bottom of a moving gate and the ground is greater than 101.6 mm (4″) and less than 406 mm (16″); or b. The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6 mm (4″).

Requirements. A minimum of two independent monitored entrapment protection devices are required to be installed at each entrapment zone. It is the responsibility of the installer to install external monitored entrapment protection devices for each entrapment zone. The operator will only operate with a minimum of two independent monitored entrapment protection devices installed in either the open or closed direction. If no entrapment zone exists in the other direction, an external entrapment protection device is NOT required in that direction. This operator has an inherent entrapment protection device built-in. The installer MUST provide one additional entrapment protection device for each entrapment zone.

Acceptable entrapment protection device types include: inherent (built into the operator), LiftMaster monitored external photoelectric sensors, and LiftMaster monitored external edge sensors.

SAFETY

IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of INJURY or DEATH: READ AND FOLLOW ALL INSTRUCTIONS. NEVER let children operate or play with gate controls. Keep the remote control away from children. ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE. Test the gate operator monthly. The gate MUST reverse on contact with an object or reverse when an object activates the noncontact sensors. Use the manual release ONLY when the gate is not moving. KEEP GATES PROPERLY MAINTAINED. The entrance is for vehicles ONLY. Pedestrians MUST use separate entrance. SAVE THESE INSTRUCTIONS.

Safety Installation Information

1. Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. 2. Gate operating system designers, installers, and users must take into account the possible hazards associated with each individual application. 3. A gate operator can create high levels of force in its function as a component part of a gate system. Specific safety features include: Edge Sensors (contact), Photoelectric Sensors, and Instructional and Precautionary Signage. 4. Install the gate operator only when the operator is appropriate for the construction and usage class of the gate, and all exposed pinch points are eliminated or guarded. 5. The gate operator is intended for installation only on gates used for vehicles; pedestrians must be supplied with a separate access opening located so persons will not come in contact with the vehicular gate. 6. The gate must be installed with enough clearance between the gate and adjacent structures to reduce the risk of entrapment. Swinging gates shall not open into public access areas. 7. The gate must work freely in both directions prior to installing the operator. 8. Permanently mounted access controls must be located at least 6 feet (1.8 m) away from any moving part of the gate. 9. Stop and/or Reset buttons must be located in the line-of-sight of the gate. 10. A minimum of two (2) WARNING SIGNS shall be installed so at least one is visible from each side of the gate. 11 and 12. Non-contact and contact sensor placement rules apply per UL 325, including a contact sensor on the bottom edge if that edge sits between 4 and 16 inches above grade at any point in its travel.

SAFETY

INTRODUCTION

Site Preparation

Check the national and local building codes BEFORE installation. Refer also to the Site Planning Safety Checklist in the Appendix. Trench and install conduit. Before trenching, contact underground utility locating companies. Conduit must be UL approved for low and high voltage. Vehicle loops allow the gate to stay open when vehicles are obstructing the gate path, suggested for vehicles 14 feet (4.27 m) or longer. Vehicle loops are not required but are recommended. Before installing your Access Control Device(s) be sure to complete a site survey and determine the best device for your site needs.

Entrapment protection devices are required to protect against any entrapment or safety conditions encountered in your gate application. Install a warning sign (two provided) on the inside and outside of the property, where easily visible. Gate must be constructed and installed according to ASTM F2200 standards and must fit specifications of the operator.

Check Your Gate

Gate MUST be level. Gate and gate post MUST be plumb. Gate MUST have a smooth bottom edge, no protrusions should exist. Remove ANY/ALL wheels from the bottom of gate. Gate MUST NOT hit or drag across ground. Gate MUST swing freely and be supported entirely by its hinges.

INTRODUCTION

CAUTION: To AVOID damaging gas, power or other underground utility lines, contact underground utility locating companies BEFORE digging more than 18 inches (46 cm) deep. ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment.

Do's

Weld a horizontal bar across entire gate on any installation for strength. Make sure that the operator is mounted level or it will not function properly. Make sure there is slack in the operator cable. The operator can be mounted on top of the gate frame. The operator must be installed at least 12″ (30 cm) from the ground.

Don'ts

DO NOT install upside down. DO NOT install next to sprinklers or any area that may expose the bottom of operator to water. DO NOT install on uphill or downhill gates. DO NOT install on ANY pedestrian passageways, doorways, or gates. DO NOT over-bend the operator cable. DO NOT weld the crossbar on just a few pickets, or they could bend.

INSTALLATION

Step 1 Position the Brackets

If this operator is a replacement for a Miracle-One™ operator, use the existing post bracket and gate bracket. If your application is Push-to-Open, refer to the illustrations in the Appendix. The measurements shown are typical for a standard installation.

1. Close the gate. 2. Choose a vertical mounting location for the post bracket. 3. Place a measuring tape under the center of the gate hinge point and measure out dimension A (see chart). 4. Mark the location of the first measurement. 5. Measure out dimension B from the previous mark. 6. Align the post bracket as close as possible above the mark and tack weld it in the desired vertical position. 7. Position a level on the post bracket and measure 35-1/2″ (90.2 cm) over from the center hole of the post bracket and mark the location on the gate. 8. Measure 2-1/4″ (6.4 cm) down from the previous mark and center the gate bracket on this mark, then tack weld it.

Dimension Chart (A / B)

7-3/4″ (19.7 cm) / 8-1/2″ (21.6 cm) — 8-1/2″ (21.6 cm) / 7-3/4″ (19.7 cm) — 9″ (22.9 cm) / 9″ (22.9 cm) — 9″ (22.9 cm) / 8-1/2″ (21.6 cm) — 7-1/2″ (19.1 cm) / 7-1/2″ (19.1 cm)

NOTES: There should only be a maximum of 4″ (10.2 cm) from the center of the hinge to the edge of the post or column; if greater, entrapment protection for this area is required. While the gate is in the fully open position, the operator needs a clearance of 11-1/4″ (28.6 cm). The ideal installation measurements are A = 7-3/4″ and B = 8-1/2″. If different measurements are used, the sum of A and B cannot be greater than 18″ (45.7 cm).

INSTALLATION

Step 2 Attach the Brackets

1. Insert the key into the lock and turn it 180 degrees counterclockwise. Turn the release lever 180 degrees counterclockwise. The operator is now in manual mode. 2. Position the operator on the brackets and make sure the operator is level and positioned correctly on the gate. 3. Remove the operator from the gate. 4. Completely weld around the post bracket and gate bracket. NOTE: Brackets may need additional reinforcement by welding flat stock. 5. Attach the operator to the post bracket with the bolt, mounting plate, and nut. 6. Attach the gate bracket to the operator with the bolt, washer, and nut. Tighten the nut until it reaches the bottom of the gate bracket, then turn a half turn more, without overtightening. Make sure the trolley does not reach the fully open or fully closed position.

For dual gate applications, repeat the previous installation steps to install the second operator.

INSTALLATION

Step 3 Install the Control Box - Standard Control Box

The control box MUST be mounted within 5 feet (1.52 m) of the gate operator. Mount the control box as high as possible for best radio reception. Make sure the control box is level. NOTE: The expansion board DOES NOT need to be removed for a wall or column mount installation.

1. Remove the screws and open the control box. 2. Disconnect the "Main Board" connector from the expansion board. 3. Remove the expansion board by removing the screws. 4. Select the mounting holes (according to your application) and remove the knockouts. 5. Secure the control box to the mounting surface: A. Wall or Column: Use the provided screws (4). B. Post: Use U-bolts and rubber washers (not provided) to ensure a watertight seal, keeping the U-bolts from protruding more than 3/4 inch (this can short the control board). 6. Reinstall the expansion board and connect the "Main Board" connector to the expansion board.

INSTALLATION

Large Metal Control Box

The control box MUST be mounted within 5 feet (1.52 m) of the gate operator, as high as possible for best radio reception, and level. NOTE: The Large Metal Solar Control Box (Model XLSOLARCONTUL) does not have the electrical outlets or the expansion board.

Wall or Column Mount

1. Open the control box; the door may be removed by opening it 90 degrees. 2. Remove the toroid assembly by loosening the three screws and lifting it up and out. 3. Knock out the 4 corner holes. 4. Secure the control box to the mounting surface using the provided screws (4).

Post Mount

NOTE: The post mount option is not recommended for the 33AH battery application. 1. Open the control box. 2. Select center mounting holes (top and bottom) and knock out with a screwdriver and hammer to accommodate a 3/8″ diameter U-bolt. 3. Secure the control box with U-bolts and rubber washers (not provided) to ensure a watertight seal.

U-Bolt Opening: Standard 3″ Round Pipe = 3-1/2″, Standard 4″ Square Post = 4″, Standard 3″ Square Post = 6″.

INSTALLATION

WARNING: Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. ALL electrical connections MUST be made by a qualified individual. ALL power and control wiring MUST be run in separate conduit.

Step 4 Earth Ground Rod

Use the proper earth/ground rod for your local area. The ground wire must be a single, whole piece of wire, never spliced. 1. Install the earth/ground rod within 3 feet (.9 m) of the operator. 2. Run wire from the earth/ground rod to the control box. NOTE: If the operator is not grounded properly the range of the remote controls will be reduced and the operator will be more susceptible to lightning and surge damage.

Step 5 Wire the Operator Arm to the Control Board

1. Choose a knockout in the bottom of the control box. 2. Insert the operator cable through the provided watertight connector. 3. Insert the operator cable and watertight connector into the knockout. 4. Slide the connector nut onto the operator cable. 5. Connect the operator cable wires to the connector according to the colored label (white to white, red to red, etc.). 6. Plug the connector into the GATE 1 terminal on the control board. 7. Tighten the connector nut. If installing one operator, proceed to Step 7. If installing two operators, continue to Dual Gate Setup.

INSTALLATION

Step 6 Dual Gate Setup

There are two options for dual gate communication: wired or wireless. Do not use wired and wireless communication simultaneously. Wired applications have a longer battery standby time than wireless applications. Wireless dual gates require two control boxes, one for each operator arm.

Wireless Setup

1. Choose an operator to be the network primary operator. 2. Press and release the LEARN button on the primary operator; the green XMITTER LED will light. NOTE: The operator will time out of programming mode after 180 seconds. 3. Press and release the LEARN button again; the yellow NETWORK LED will light. 4. Press and release the OPEN test button to assign this operator as network primary. 5-6. Repeat the LEARN button sequence on the second operator. 7. Press and release the CLOSE test button to assign this operator as network second. Both operators will beep and the yellow NETWORK LEDs will turn off, indicating success.

To deactivate: press LEARN once, then press LEARN again, then press and hold LEARN for 5 seconds until the NETWORK LED blinks and turns off. Repeat on the other operator.

INSTALLATION

Wired Setup

Install a second operator arm, then install the extension cable and junction box. Before digging, contact local underground utility locating companies. 1. Trench across the driveway to bury the extension cable, using PVC conduit. 2. Open the junction box. 3. Select mounting holes and drill two holes large enough for the watertight connectors. 4. Mount the junction box within 3 feet (0.9 m) of the second operator. 5-7. Route the operator cable and extension cable through the watertight connectors into the junction box. 8. Connect the wires from the extension cable and operator cable to the terminal block connector (like-colored wires facing each other). 9-11. Secure the wires, tighten the connector nuts, and reinstall the cover.

INSTALLATION

1-7. Wire the secondary operator arm to the control board through a knockout, watertight connector, and the GATE 2 terminal, following the same colored-wire matching process as Gate 1.

Set the Bipart Delay (single control box)

Occasionally in dual gate installations, one gate needs to open first and close second, such as with an ornamental overhang or a solenoid lock. This is the Primary gate and connects to the GATE 1 terminal. The BIPART DELAY switch on the control board needs to be set to ON.

Set the Bipart Delay (dual control box)

BIPART DELAY: used where a mag-lock, solenoid lock, or decorative overlay requires one gate to close before the other. SYNCHRONIZED CLOSE: used where one gate travels a longer distance; set BIPART DELAY to ON for both control boxes to synchronize closing.

INSTALLATION

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.

Step 7 Install Entrapment Protection

1. Install entrapment protection devices for ALL entrapment zones. This operator has an inherent entrapment protection device built-in; the installer MUST provide one additional device per entrapment zone. 2. The operator will NOT run unless a minimum of one external device is connected in either the open or closed direction. If no entrapment zone exists in the other direction, an external device is NOT required there. 3. Test ALL entrapment protection devices AFTER installing the operator.

INSTALLATION

There are three options for wiring external entrapment protection devices. These inputs are for monitored devices only, which include pulsed photoelectric sensors, resistive edge sensors, and pulsed edge sensors. Only one monitored device may be wired to each input; additional devices go on the expansion board.

Control Board Inputs

CLOSE EYES/INTERRUPT (2 Terminals): For photoelectric sensor entrapment protection in the close direction. An obstruction reopens the gate fully and resets the Timer-to-Close.

CLOSE EDGE (2 Terminals): For edge sensor protection in the close direction. An obstruction reverses the gate to full open, disengaging the Timer-to-Close.

OPEN EYES/EDGE (2 Terminals): For photoelectric or edge sensor protection in the open direction. An obstruction reverses the gate for 4 seconds then stops.

Expansion Board Inputs

EYE ONLY and COM: Open or close direction photoelectric sensors, functionality set by a nearby switch. EYE/EDGE and COM: Open or close direction photoelectric or edge sensors, functionality set by a nearby switch.

INSTALLATION

Step 9 Power Wiring

The standard control box can be wired for either 120 Vac or 240 Vac; factory default is 120 Vac. Batteries are charged by the toroid transformer, plug-in transformer, or solar panels. Main power and control wiring MUST be run in separate conduits. Use copper conductors ONLY.

Standard Control Box Steps

1. Turn off AC power at the main breaker. 2. Run AC power wires to the control box. 3. Remove the toroid assembly by loosening the four screws. 4. Ensure the 120/240 plug is connected to the correct EMI board connector. 5. Connect the ground wire to the ground screw on the back of the toroid assembly. 6. Connect the white wire to NEUTRAL. 7. Connect the black wire to HOT. 8. Replace the toroid assembly. 9. Plug the J15 plug into the control board (a small spark is normal). 10. Turn ON AC power.

Wire Gauge Distance (120 Vac)

14 gauge: 350 ft (107 m). 12 gauge: 525 ft (160 m). 10 gauge: 850 ft (259 m). OR at 240 Vac: 14 gauge: 1,150 ft (351 m). 12 gauge: 1,850 ft (564 m). 10 gauge: 2,950 ft (899 m).

INSTALLATION

To use solar panels with the Large Metal Control Box (Model XLSOLARCONTUL), skip these steps and refer to Solar Panels in the Appendix.

1. Unplug the J15 plug labeled BATT(-)(+) DC(-)(+). 2. Turn off AC power at the breaker. 3-4. Run AC power wires and remove the toroid assembly (three screws). 5. Confirm the 120/240 plug setting. 6-8. Connect ground, neutral, and hot wires, then replace the toroid assembly. 9-12. Connect a jumper between one battery's positive terminal and the other's negative terminal, then connect the red J15 wire to the positive terminal and the black J15 wire to the negative terminal. 13. Plug the J15 plug into the control board. 14. Turn ON AC power.

All control wiring to Class 2 circuits must be Power-Limited Circuit Cable Type CL2, CL2P, CL2R, or CL2X or better.

INSTALLATION

Step 10 Install Warning Signs

Installers MUST install the UL required warning signs in plain view on both sides of each gate installed. Use the fastening holes in each corner to permanently secure the sign.

Step 11 Finish the Installation

1. Turn the release lever clockwise 180 degrees back to the engaged position; this engages the motor. 2. Turn the key clockwise 180 degrees; this locks the release lever. The operator is now engaged.

INSTALLATION

WARNING: Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a moving gate. NEVER increase force beyond the minimum amount required to move the gate. NEVER use force adjustments to compensate for a binding or sticking gate. After ANY adjustments are made, the safety reversal system MUST be tested.

Introduction

The electronic controls sense the amount of force required to open and close the gate. Force is adjusted automatically when you program the limits but should be fine-tuned using the REVERSAL FORCE dial to compensate for environmental changes. The limits can be set using the control board or a remote control (a 3-button remote programmed to OPEN, CLOSE, and STOP).

Limit Setup LEDs

SET OPEN off / SET CLOSE off = Normal Mode, limits are set. Both blinking = Limit Setting Mode, limits are not set. SET OPEN blinking / SET CLOSE on = open limit not set. SET OPEN on / SET CLOSE blinking = close limit not set. Both on = Limit Setting Mode, limits are set.

ADJUSTMENT

For dual gate applications the limits must be set for each operator. The gate MUST be attached to the operator before setting limits and force. If a mistake is made, press the reset button to start over.

1. Set the GATE switch to the 1 position. 2. Press and release SET OPEN and SET CLOSE simultaneously to enter limit setting mode. 3. Press and hold the MOVE GATE buttons to move the gate to the open or close limit. 4. Press and release SET CLOSE or SET OPEN depending on which limit is being set. 5-6. Repeat for the other limit; the operator exits limit setting mode. 7. Cycle the gate open and close using the TEST BUTTONS; this automatically sets the force. 8. For dual gates, set the GATE switch to position 2 and repeat steps 2-7.

ADJUSTMENT

Fine Tune the Force

The REVERSAL FORCE DIAL is set to minimum at the factory. The force setting should be high enough that the gate will not reverse by itself or cause nuisance interruptions, but low enough to prevent serious injury. 1. Open and close the gate with the TEST BUTTONS. 2. If the gate stops or reverses before reaching a limit, increase force by turning the dial slightly clockwise. 3. Perform the Obstruction Test after every adjustment.

Obstruction Test

1. Open and close the gate with the TEST BUTTONS, confirming it stops at the proper limits. 2. Place an object between the open gate and the fixed closed catch post, or obstruct by hand, without triggering external entrapment devices. 3. Run the gate in the close direction; it should stop and reverse on contact. If it does not reverse, reduce force slightly counterclockwise. 4. Repeat the test for the open direction.

ADJUSTMENT

A total of 50 Security+ 2.0® remote controls or KPW250 keypads and 2 keyless entries can be programmed to the operator. NOTE: If installing an 86LM to extend range, DO NOT straighten the antenna.

Programming Options

In case of a power failure, the operator can be disengaged from the gate. NOTE: It is normal for the operator to run slow right after a disconnect or complete loss of power. Release: insert the key, turn it counterclockwise 180 degrees, then turn the release lever counterclockwise 180 degrees. Engage: turn the release lever clockwise 180 degrees, then turn the key clockwise 180 degrees, then remove and store the key.

Reset Button

Located on the side of the control box. Stops a moving gate like a stop button, disables the Timer-to-Close while the gate is open, and shuts off the alarm to reset the operator.

Party Mode

Press the reset button once while the gate is open to disable the Timer-to-Close; the gate stays open until the reset button is pressed again or a programmed remote is activated. Can also be enabled from a KPW5 or KPW250 keypad using a valid 4-digit PIN. NOTE: Using Party Mode at a solar site will deplete the batteries.

OPERATION

Operator Alarm

When the inherent force of the operator detects the following twice consecutively, the alarm will sound up to 5 minutes and the operator will need to be reset: the gate hitting an obstruction, the arm or gate being incorrectly installed, the gate not meeting specifications, hinges too tight or broken, a car pushing the gate, a foreign object on the gate frame, or the gate hitting the driveway/curb and getting stuck. Remove obstructions and press the reset button to shut off the alarm. The alarm will beep 3 times with a command if the battery is low.

Remote Control (Single Button Control)

When the gate is closed, activating the remote opens it; a second activation during the open cycle stops the gate; a third activation closes it. When the gate is open, activation closes it; if activated while closing, the gate stops and the next activation reopens it.

OPERATION

All control wiring to Class 2 circuits must be Power-Limited Circuit Cable Type CL2, CL2P, CL2R, or CL2X or better. NOT TO BE USED AS ENTRAPMENT PROTECTION.

EXIT (2 Terminals): A soft open command for exit probes, telephone entry, external exit loop detectors, or any device commanding the gate to open. Opens a closed/closing gate; holds an open gate open if maintained.

SHADOW (2 Terminals): For a shadow loop detector positioned under the swing of the gate. Holds the gate open at the limit; only active at the OPEN limit.

INTERRUPT (2 Terminals): For an interrupt loop detector on the outside of the gate. Holds the gate open at the limit, stops and reverses a closing gate, and activates quick close/anti-tailgate features when enabled on the expansion board.

ACCESSORY WIRING

Maglock (LOCK, 2 Terminals, N.C. and COM)

Relay contact output, normally-closed for maglocks. The relay activates prior to and during motor run, and turns off when the motor is off.

Miscellaneous Wiring

Single Button Control (SBC) (2 Terminals): Gate command sequence Open, Stop, Close, Stop. Fire Department Open Input (2 Terminals): Acts as a hard open; a maintained input overrides external safeties and re-enables the Timer-to-Close. Accessory Power 24 Vdc, max 500 mA (4 Terminals): Switched (on during motion and open-limit timer, off 5 seconds after motion) or Unswitched (always on).

ACCESSORY WIRING

CAUTION: To AVOID damaging the circuit board, relays or accessories, DO NOT connect more than 42 Vdc (32 Vac) to the AUX relay contact terminal blocks.

QUICK CLOSE switch: when ON, deactivating the CLOSE EYES/Interrupt loop causes an opening or stopped gate to close, ignoring the Timer-to-Close. AC FAIL switch: OPEN causes the gate to open on AC power loss and stay open; BATT keeps the gate in place, running on batteries. EXIT FAIL switch: controls behavior when the plug-in EXIT loop detector faults. ANTI-TAIL switch: OFF reverses a closing gate on interrupt activation; ON pauses the closing gate instead. AUX RELAY switches and EYE/EDGE switches configure auxiliary relay behavior and sensor direction. Also includes the 1/2/3 LEDs for input status and firmware version display, the MAIN BOARD input connector, loop detector inputs, and the wireless edge input.

EXPANSION BOARD

Normally Open (N.O.) and Normally Closed (N.C.) relay contacts for external devices, Class 2 low voltage (42 Vdc / 34 Vac max, 5 Amps). Function is set by three dipswitches per relay: Off (always off, conserves battery), Open Limit Switch (energizes at open limit, use with SAMS), Close Limit Switch (energizes when not at close limit), Gate Motion (energizes when motor runs), Pre-Motion Delay (energizes 3 seconds before motion), Power (energizes when AC/solar power is present, or on battery power for relay 2), Tamper (energizes if the gate is manually pushed off the close limit), and Cycle Quantity Feedback (blinks out the total cycle count on relay 1 only).

EXPANSION BOARD

A red light wired to AUX RELAY 1 and a green light wired to AUX RELAY 2 can indicate gate state: closed (red off, green off), opening/closing (red on/flashing, green off), open (red off, green on), and various timer states. Auxiliary relay wiring requires a Class 2 power source rated 42 Vdc (34 Vac) max, 5 Amps, connected to the warning light's N.C., COM, and N.O. terminals as needed.

EXPANSION BOARD

The expansion board provides inputs for: wireless edge receivers; EYES ONLY and EYES/EDGE entrapment protection devices (direction set by nearby switches); Single Button Control; a 3-Button Control Station (Open, Close, Stop with common); an Exit Loop Input; a Shadow Loop Input; and an Interrupt Loop Input. Each loop input behaves the same way as its main-board counterpart described in Accessory Wiring.

EXPANSION BOARD

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 and does NOT turn off battery power. ALWAYS disconnect the batteries to service the operator. To reduce the risk of FIRE or INJURY, use ONLY LiftMaster part 29-NP712 for replacement batteries.

Batteries degrade over time depending on temperature and usage; the alarm beeps 3 times with a command if the battery is low. Replace every 3 years using only LiftMaster part 29-NP712. The standard control box uses two 7AH batteries; a Large Metal Control Box solar installation may use two 33AH batteries (A12330SGLPK) with a battery tray (K10-36183) and harness (K94-37236).

MAINTENANCE

To view codes: press and hold STOP, then CLOSE, then OPEN until "Er" shows on the display. The operator shows the code sequence number (01 is most recent) followed by the code itself. Press OPEN to scroll to the most recent code; press CLOSE to scroll to 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.

TROUBLESHOOTING

Status LEDs: INPUT POWER (on when AC/solar available), BATT CHARGING (on during three-stage charging), TIMER (off/on/blinking states show timer running, paused, or canceled), GATE MOVING (on when opening/closing; blink patterns indicate single or double entrapment), BATT LOW (on = low, blinking = critically low), ACC PWR OVLD (on = accessory overload tripped).

Input LEDs: SBC, FIRE DEPT, EXIT, SHADOW, CLOSE EYES/INTERRUPT, CLOSE EDGE, and OPEN EYES/EDGE each show off (inactive), on (active), or blinking (active on the other operator or expansion board). LOCK LED shows whether the maglock relay is active.

Covers Pull-to-Open and Push-to-Open configurations for both column and post installations, with reinforcement steel plate guidance for each, and a note to weld rebar behind gate hinges for maximum strength.

APPENDIX

For Push-to-Open applications, a hole schedule and reinforcement plate (fabricated on site) locates the brackets 35-1/2″ (90.2 cm) apart with additional hole spacing of 7-3/4″ and 8-1/2″ as shown in the dimension chart.

APPENDIX

SOLAR PANELS ARE NOT PROVIDED. SEE ACCESSORIES.

33AH Battery Requirements

Large Metal Control Box for Solar Applications (XLSOLARCONTUL), a minimum of two and maximum of six 10W solar panels (SP10W12V), two 33AH batteries (A12330SGLPK), solar battery harness (K94-37236), and battery tray (K10-36183).

7AH Battery Requirements

Standard Control Box for Solar Applications (LA500CONTUL), the same solar panel range, two 7AH batteries (29-NP712), and solar battery harness (K94-37236).

Solar Zones

Zone 1 (6 hours sunlight/day) is ideal for solar; Zone 2 (4 hours) is recommended; Zone 3 (2 hours) success depends on operator type and panel placement. Solar installations are not supported in northern climates or areas with heavy fog, lake effect snow, or rain.

APPENDIX

Typical standby battery current draw at 24V: main board with no radios, 2.7 mA; each LiftMaster remote programmed, +1 mA; myQ device or wireless dual gate, +2.4 mA; expansion board, +11.1 mA; each plug-in loop detector, +3.8 mA (up to 3 supported). NOTE: photoelectric sensor heaters (LMRRUL, LMTBUL) are not recommended in solar applications.

Cycles per day scale with solar zone, panel wattage (10W to 60W), and battery size (7AH or 33AH). A 60W panel with 33AH batteries in Zone 1 supports up to roughly 300 cycles per day for a single gate; the same setup in Zone 3 drops to as low as 24 to 39 cycles per day. All figures are estimates; actual results vary by gate construction, installation, and temperature.

APPENDIX

Solar panels must be mounted facing due south (verify with a compass), 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. Installation: position the mounting bracket, secure the panel to the bracket with the provided hardware, then secure the bracket to the mounting surface with lag screws.

The Solar Harness Kit (K94-37236) wires the batteries and solar panels. 33AH batteries wire in series with red, black, and a white jumper wire; 7AH batteries follow the same series wiring pattern. Solar panels wire in series for 20W, 40W, and 60W configurations depending on the number of panels used.

APPENDIX

Requires a 3-button remote programmed for OPEN, CLOSE, and STOP (Security+ 2.0 Model 813LMX recommended; SP3 remotes are not recommended for this task). With the gate closed, press SET OPEN and SET CLOSE together to enter limit setting mode, jog the gate to the desired open position using the remote, press STOP to confirm, then press OPEN again to set that limit. Repeat the process using CLOSE and STOP to set the close limit. Cycling the gate afterward sets the force automatically.

APPENDIX

The Sequenced Access Management System (SAMS) uses programmable relays to determine the order in which multiple control devices operate across an opening, such as a swing gate opening fully before a barrier arm activates. This wires the barrier arm operator's auxiliary command input to the Exit Input on one control board and the Shadow Input on the expansion board of the other, with AUX Relay 1 dipswitches set to 1-OFF, 2-OFF, 3-ON.

ACCESSORIES

LiftMaster warrants to the first purchaser of this product, for the structure in which it is originally installed, that it is free from defect in materials and/or workmanship for 2 years from the date of purchase. Proper operation depends on compliance with the installation, operation, maintenance, and testing instructions in this manual; failure to comply voids this warranty entirely.

Call 1-800-528-2806 before dismantling the product if a defect appears during the warranty period. Include a brief description of the problem and a dated proof-of-purchase receipt with any returned product.

This warranty does NOT cover non-defect damage, damage from improper installation or care, labor for reinstalling a repaired unit, or battery replacement. It also does NOT cover problems with the gate or gate hardware (springs, rollers, alignment, hinges) or problems caused by interference. Seller liability under this warranty is limited to the cost of the product.

WARRANTY

LiftMaster provides a UL 325 and ASTM F2200 Site Planning Safety Checklist for dealers and installers to document at installation: gate construction compliance (smooth bottom edges, access control clearance of 6 feet, barbed tape/wire height, separate pedestrian gate, no self-closing under gravity), swing-specific checks (pivot-to-column clearance under 4 inches or protected, open-gate clearance of at least 16 inches or protected), and general UL 325 checks (operator label current to standard, warning signs on both sides, both entrapment zones protected by two safety devices and obstruction tested).

A minimum of two independent entrapment protection devices must protect every entrapment zone. A swing gate operator will only operate with a minimum of one external device in either the open or close direction; if no entrapment zone exists in the other direction, only the inherent protection is required there. The checklist should be signed by the dealer, installer, and customer, and a photograph of the completed installation should be kept on file.
