ROLE OF SPECIFIERS AND DESIGNERS

ROLE OF DEALERS, INSTALLERS
AND TRAINED SYSTEM TECHNICIANS
Specifiers and designers should design an automatic vehicular gate system to:
Installers, during the course of the installation steps for each job, should:
Read and fully understand the manual. Confirm that the operator being installed is appropriate for the application. Confirm that the gate is designed and built according to current published industry standards. Confirm that all appropriate features and accessory devices are being incorporated, including both primary and secondary entrapment protection devices. Make sure that the gate works freely before installing the operator. Repair or service worn or damaged hardware before installing the operator. Adjust the operator clutch or load-sensing device to the minimum force setting that allows reliable operation. Install operator inside fence line. (DO NOT install operator on public side of fence line.) Install a proper electrical ground to the operator. Install keypad controls where users cannot touch, or reach through gate while operating controls. Install controls where user has full view of operation. Install all warning signs (in accordance with UL325) on both sides of the gate to warn persons in the area of potential hazards associated with automatic vehicular gate operation. Test all features for proper functions before placing the automatic vehicular system into service. Demonstrate the basic functions and safety features of the system to owners/end users/general contractors, including how to turn off power and how to operate the manual disconnect feature. Leave safety instructions, product literature, installation manual and maintenance manual with end user. Explain to the owners the importance of a service/maintenance contract that includes a routine re-testing of the entire system including the entrapment protection devices, and explain the need for the owners to insure that this testing is performed routinely. Offer the owner/end user a maintenance contract, or contact them regularly to offer maintenance.
Incorporate UL325 compliant equipment. Utilize an operator suited for system type, size, frequency of use, location and user population. (For gates refer to UL325 for usage class definitions.) Separate pedestrian access from vehicle access. Reduce or eliminate pinch points. Reduce risk of entrapment injuries by minimizing all gaps in the gate and enclosing the area of the travel of the gate. Secure controls from unauthorized use. Locate all controls out of reach from the gate. Allow the user full view of the gate when operating. Consider special populations, such as children or the elderly. Prominently display all warnings and instructions. Be consistent with DASMA’s Automatic Gate Opener System Safety Guide.

ROLE OF END USERS

OVERHEAD GATE SYSTEMS

Read and fully understand the manual. Contact a trained system technician to maintain and repair the system. (End users should never attempt to repair the system.) Retain and utilize the installation/maintenance manual and safety instructions. Routinely check of all operator functions and gate movement. Discontinue use if safety systems operate improperly, the gate is damaged, or the gate is difficult to move. Prominently display and maintain warning signs on both sides of the gate. Keep all obstructions clear of the vicinity of the path of the system. Actively discourage pedestrian use of the vehicular operating system. Prevent anyone from playing near any part of the system. Never allow anyone to climb under, over or through a gate or the adjacent fence area. Never allow children to operate system. Keep portable controls out of reach of children. Never allow anyone to install an operating control within reach of the gate. Always be certain that the area is clear of pedestrians before operating the system.
End users should be made aware that they must:
READ AND FOLLOW ALL INSTRUCTIONS.
Gate - A moving barrier such as a swinging, sliding, raising lowering, rolling, or like, barrier, that is a stand-alone passage barrier or is that portion of a wall or fence system that controls entrance and/or egress by persons or vehicles and completes the perimeter of a defined area.
Vehicular Vertical Pivot-Gate Operator (or System) - A vehicular gate operator (or system) that controls a gate that moves in an arc in a vertical plane that is intended for use for vehicular entrances or exits to a drive, parking lot, or the like.
Entrapment Zone Hazard - Body parts may become entrapped between a gate and a stationary object when the gate begins to move, which can result in serious injury or death. Pedestrians must stay clear of the gate path, and any area where gate motion is close to stationary objects.
Pinch Points Hazard - The opening mechanism may have arms that can overlap with a scissoring effect, which can result in serious injury. Pedestrians must stay clear of the opening mechanism at all times, particularly when gate is opening.
Be sure that warning signs are prominently displayed on both sides of the gate and any other place where danger exists.

6)
1)
Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application. Improperly designed , installed or maintained systems can create risks for the users as well as bystanders. Gate systems design and installation must reduce public exposure to potential hazards. A gate operator can create high levels of force in its function as a component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include:
• Gate edges • Guards for Exposed Rollers • Photoelectric Sensors
• Screen Mesh • Vertical Posts • Instructional and Precautionary Signage Install the gate operator only when:
A) The operator is appropriate for the construction and the usage class of the gate. B) All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 4' (1.2 m) above the
ground to prevent a 2 1/4" (6 cm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position.
C) All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers.
The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate such that persons will not come in contact with the vehicular gate during the entire path of travel of the vehicular gate.
The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening and closing to reduce the risk of entrapment. Swinging gates shall not open into public access areas.
The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.
Controls intended for user activation must be located at least 6' (1.8 m) away from any moving part of the gate and where the user is prevented from reaching over, under, around or through the gate to operate the controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use.
The Reset Button must be located in the line-of-sight of the gate. Activation of the reset control shall not cause the operator to start.
A minimum of two (2) WARNING SIGNS shall be installed, one on each side of the gate where easily visible.
For a gate operator utilizing a non-contact sensor:
A) Reference owner’s manual regarding placement of non-contact sensor for each type of application. B) Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still
moving.
C) One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the perimeter
reachable by a moving gate or barrier.
For a gate operator utilizing a contact sensor such as an edge sensor:
A) Reference owner’s manual regarding placement of non-contact sensor for each type of application. B) One or more contact sensors shall be located where the risk of entrapment or obstruction exists, such as at the leading edge,
trailing edge and post mounted both inside and outside of a vehicular horizontal slide gate.
C) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate. D) A hard wired contact sensor shall be located and its wiring arranged so the communication between the sensor and the gate
operator is not subject to mechanical damage.
E) A wireless contact sensor such as the one that transmits radio frequency (RF) signals to the gate operator for entrapment
protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end-use conditions.
F) One or more contact sensors shall be located on the inside and outside leading edge of a swing gate. Additionally, if the bottom
edge of a swing gate is greater than 6" (152 mm) above the ground at any point in its arc of travel, one or more contact sensors shall be located on the bottom edge.
G) One of more contact sensors shall be located at the bottom edge of a vertical barrier (arm).

HOW TO CONNECT POWER (120VAC)

Proper grounding gives an electrical charge, such as from an electrical static discharge or a near lightning strike, a path from which to dissipate its energy safely into the earth.
Without this path, the intense energy generated by lightning could be directed towards the operator. Although nothing can absorb the tremendous power of a direct lightning strike, proper grounding can protect the operator in most cases.
The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you should cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length.
Use the proper type earth ground rod for your local area. In certain circumstances, metal water pipes may be allowed for grounding the operator. Check and follow all local codes for proper grounding procedures.
Black = 120 Vac Wire
White = Neutral Wire
Green = Earth Ground Wire
Use UL Listed conduit to enclose power wires
Chamberlain Professional Products is not responsible for improper installation or failure to comply with all necessary local building codes.
CAUTION:
To avoid damaging gas, power, or other underground utility lines, contact
local underground utility locating companies before digging.
STEP 6
Minimum 12 Gauge Ground Wire connected to HCT Earth Ground Wire
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with local electrical codes. NOTE: The operator
should be on a separate fused line of adequate capacity.
• ALL electrical connections MUST be made by a qualified individual.
• Do not install any wiring or attempt to run the operator without consulting the wiring diagram. We recommend that you install an optional reversing edge BEFORE proceeding with the control station installation.
• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled.
• ALL power and control wiring must be run in separate conduit.
• BEFORE installing power wiring or control stations, be sure to follow ALL specifications and warnings described below. Failure to do so may result in SEVERE INJURY to persons and/or damage to operator.
• Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate.
