IMPORTANT SAFETY INSTRUCTIONS
WARNING - To reduce the risk of SERIOUS INJURY or DEATH:
1.READ AND FOLLOW ALL INSTRUCTIONS.
2.Never let children operate or play with gate controls. Keep the remote control away from children.
3.Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE.
4.Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death.
5.Use the emergency release only when the gate is not moving.
6.KEEP GATES PROPERLY MAINTAINED. Read the owner's manual. Have a qualified service person make repairs to gate hardware.
7.The entrance is for vehicles only. Pedestrians must use separate entrance.
8.SAVE THESE INSTRUCTIONS.
WARNING! Children should never be allowed to play near or operate automatic gates. Failure to observe safe operating procedure, train your customer properly, or install proper warning signage may result in serious injury.

WHAT TO EXPECT FROM A CLASS 1, 2, 3 OR 4 OPERATOR
SAFETY INSTRUCTIONS REGARDING PRIMARY & SECONDARY ENTRAPMENT PROTECTION.
This unit is provided with two means of entrapment protection (see UL-325). A gate operator shall provide one Primary (inherent) and one Secondary entrapment feature.
Primary: (Type A) Inherent entrapment sensing systems
The MEGA SWING UL will reverse direction when the inherent type “A” device senses an obstruction.
Secondary: (Type B1 & B2) Provision for connection of a contact and non-contact sensor (photo electric, see UL-325 approved). The MEGA SWING UL will stop and sound the alarm when a B1 type device is activated.
Primary protection designated type A inherent protection. Unit will reverse direction when an obstruction is sensed while moving in either direction. Sensitivity is adjusted by IRD1 on the control board. While closing, if an obstruction is sensed by the primary inherent sensor, the gate will reverse and open to the full open position. The gate will remain there until a close command is received or will close by timer after new input is received. In order for the gate to close by timer (if activated) a new input on terminals J5 1-8 must be given. If an input is still present when the gate reached the full open position, this input will need to be renewed or removed and another input given before the close timer will close the gate.
Entrapment alarm will activate upon the primary inherent sensor sensing a second obstruction before reaching a limit switch. Once activated, gate will remain at rest and the alarm will sound. This condition can only be cleared by an input applied to J5 #4. The wiring used to reset the operator must be in the line of sight and must be an “intended” reset. Access control devices of any kind that required intended (on purpose) activation may be used for this reset. Devices that will cause an incidental reset (vehicle detectors, probes, timers, motion sensors, photo beams, etc.) must not be used. Failure to comply with this requirement may result in serious injury or death.
UL-325 DEFINITION OF GATE OPERATOR CLASSES
Residential Vehicular Gate Operator - Class I:
A vehicular gate operator/system intended for use in a home of one-to four single family dwelling, or garage or parking area associated therewith.
Commercial/General Access Vehicular Gate Operator - Class II:
A vehicular gate operator/system intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units), hotels, garages, retail stores, or other buildings servicing the “general public.”
Industrial/Limited Access Vehicular Gate Operator - Class III:
A vehicular gate operator/system intended for use in industrial locations or buildings such as factories, loading dock areas or other locations not intended to service the general public.
Restricted Access Vehicular Gate Operator - Class IV:
A vehicular gate operator/system intended for use in guarded industrial locations or buildings, such as airport security areas or other restricted access locations “not” serving the general public, in which unauthorized access is prevented via supervision by security personnel.
UL-325 APPROVED PHOTO BEAMS & CONTACT EDGES Photo beams (non-contact sensor) required:
•OMRON/MMTC Model E3K-R10K4-NR Retro-reflective type
•Allen-Bradley Model 60-2728 (with 2m cable) Retro-reflective type
•Allen-Bradley Model 60-2729 (with 5 pin term) Retro-reflective type
Safety edges (contact edge):
•Miller edge models
ME-120, ME-123, MG-020, MG020, MGR20, MGS20 Normally open contact

NOTE: This unit to employ:
Primary entrapment is an “A1” inherent entrapment sensing system with an audio alarm (reverses gate direction). Secondary entrapment is a “B1” a non-contact, photoelectric beam, connect at JP2 (stops gate, see NOTE-1). Use only UL recognized sensors. At least one secondary “stop” photo beam should be installed across and above danger zone to stop the gate operator should a person enter this area. Photo beams should be installed according to their manufacturer’s instructions and are to be placed in areas that pose a risk of entrapment. A separate pedestrian door is required per UL-325.
On swing gates that use a contact sensor, one or more contact sensors shall be located on the inside and outside leading edge of a swing gate. If the gate is greater than 6" above the ground at any point in its arc of travel, one or more contact edges shall be located on the bottom edge of the gate.

SAFETY RECOMMENDATIONS
Automatic gate operators can produce high levels of force, therefore it is very important that all gate operator system installers and designers are fully aware of potential hazards that exist with an incorrectly installed or designed system. The internal safety capabilities of a gate operator system are not enough to reduce the risk of injury. The operator is only one part of a properly installed system, which when combined with correctly installed safety devices will yield a complete system that will not only provide convenience and security, but will be safer with a minimal risk of injury.
The following information along with the check list (and the rest of the manual) is provided to make you aware of potential areas that are of a safety concern. Disregarding any of the following may result in serious injury or death.
INSTALL THE GATE OPERATOR ONLY WHEN THE FOLLOWING HAS BEEN ADDRESSED:
•Two warning signs securely installed on each side of gate panel (required).
•To reduce pinching, hinge point of gate to be within 4"-6'' of inside corner of column.
•1 or 2 safety photo beams installed, one across each side of gate opening/arc of gate.
•1 stop photo beams installed across the danger zone where drivearm is located (back area).
•Photo beams installed according to their instructions and in areas that pose entrapment risk.
•Customer advised that gate in for vehicular traffic only (required).
•A separate pedestrian entry and/or exit is provided (required).
•Contact edges installed and functional at all hazard or pinch points.
•All controls located far out of reach of gate, fixed panel and operator (required).
•This class operator is approved for the application of the operator (1, 2, 3 or 4) (required).
•Controls intended to reset gate after obstructed installed in line of sight (required).
•Hard wired contact sensors located and wired to avoid any mechanical damage.
•Customer instructed and is clear on proper use of gate operator (required).
•Customer instructed on proper use of all control devices used with operator (required).
•Safety instructions were reviewed and left with customer (required).
•Installer offered a preventative service/maintenance contract.
•A photo of completed installation taken from front and back of gate and dated.
•Advised customer on unit’s manual operation: they must remove arm cover, extend red handle/lever, pull up on extended red handle/lever to release clamp, then pull out pin.
Do not disconnect the siren in any way. Switch S1#6 must stay on and S1#8 must stay off. Tampering with the siren or switch settings may pose the risk of serious injury or death. (NOTE: Does not apply to versions 6.30 or higher. These switches were redefined for new functions. The siren cannot be disabled by changing these switches on 6.30 or higher.)
