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. Each gate system is specifically designed for an individual application.
2. Gate operating system designers, trained gate systems technicians/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 user as well as the bystander. Gate system design and installation must reduce exposure to potential hazards.
3. 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 gate system design. Specific safety features include:
   • Instructional and Precautionary Signage
   • Photoelectric Sensors (non-contact)
   • Edges Sensors (contact)
4. Install the barrier arm gate operator only when:
   • a. The barrier arm gate operator is appropriate for the construction and the usage class of the barrier arm.
   • b. All exposed pinch points are eliminated or guarded.
5. Do not install signage or anything other than the optional devices such as LEDs, foam edging, edge sensor, or wireless transmitter recommended by the manufacturer, on the barrier arm.
6. The barrier arm gate operator is intended for installation only on passageways used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage.
7. Locate the barrier arm gate operator such that persons will not come in contact with the barrier arm during the entire path of travel of the barrier arm.
8. The barrier arm gate operator must be installed in a location so that enough clearance is supplied between the barrier arm and adjacent structures when opening and closing to reduce the risk of entrapment. When the break away arm bracket is utilized, ensure it does not open into pedestrian walkways.
9. Permanently mounted access controls intended for users to activate the barrier arm, must be located at least 6 feet (1.8 m) away from any moving part of the barrier arm gate operator system and where the user is prevented from reaching over, under, around or through the gate system to operate the controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use. Exception: Emergency access controls, only accessible by authorized personnel (e.g. fire, police, EMS), may be placed at any location in the line-of-sight of the gate.
10. For a gate operator utilizing a Stop and/or Reset button, it must be located in the line-of-sight of the gate. Activation of the reset control shall not cause the operator to start.
11. A minimum of two (2) WARNING SIGNS shall be installed in the area of the barrier arm. Each warning sign is to be visible by persons located on the side of the barrier arm on which the sign is installed. Two (2) WARNING SIGNS are provided with this operator. See page 40.
12. When a hard wired contact sensor is installed it shall be located and its wiring arranged so the communication between the sensor and the gate operator is not subject to mechanical damage. A wireless edge transmitter kit must be used with the contact edge sensor.
13. A wireless device such as one that transmits radio frequency (RF) signals to the gate operator shall be located where the transmission of the signals is not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless device shall function under the intended end-use conditions.

Site Preparation

Recommendations for site preparation for barrier arm gate operator installation. Every installation is unique. It is the responsibility of the installer to ensure the barrier arm gate operator is installed in a safe manner. If the area surrounding the barrier arm gate operator is expected to have high pedestrian traffic, it is recommended that safety devices, such as Liftmaster photoelectric sensors or wireless edge sensors, be installed at the site. See "Safety Devices" on page 57 for acceptable devices.

Site Layout Diagrams

Bird's Eye View: Depicts the site layout from above.

Ground-Level View: Shows the site layout from ground level.

Site Preparation Elements:

• A Caution Lines: Permanently fix caution lines under the travel of the arm indicating a no stopping or standing zone. If a swingaway mounting style is used, the swing radius of the arm should be marked on the pavement with caution lines.
• B Speed Bump: Permanently fix speed bumps on both sides of the roadway at a straight angle, to slow traffic. Place at a minimum of 6 feet away from the barrier arm.
• C UL Warning Signs (Two Required): Permanently fix the two required UL warning signs in the area of the barrier arm gate operator. Each warning sign must be visible by persons located on each side of the barrier arm gate operator on which the sign is installed. See page 40.
• D Pedestrian Access: If pedestrian traffic is in the vicinity, a separate pedestrian entry/exit must be clearly visible to promote pedestrian usage and located so pedestrians do not come in contact with the barrier arm. Partition/barrier from vehicular traffic is recommended when possible. See callout H.
• E Speed Limit Sign: Recommend installing a permanently fixed lighted speed limit sign within line of sight from both sides of the roadway. Recommended 5mph.
• F Perimeter Lighting: Recommend installing perimeter lighting to create awareness of the area surrounding the barrier operator. If the swingaway mounting style is used, the lighting should be placed outside the swing radius of the arm.
• G Cameras: Install cameras to record operation and deter unwanted operation.
• H Partition/Barrier: Separation between vehicle and foot traffic.
• I Exit, or Reversing Loop: Protect property and manage the flow of traffic with an inground loop that reverses a closing arm for vehicle detection.

Site Preparation for Safety Devices

Every installation is unique. It is the responsibility of the installer to ensure the barrier arm gate operator is installed in a safe manner. If the area surrounding the barrier arm gate operator is expected to have high pedestrian traffic, it is recommended that safety devices, such as Liftmaster photoelectric sensors or wireless edge sensors, be installed at the site. See "Safety Devices" on page 57 for acceptable devices.

Safety Device Diagrams

Bird's Eye View: Depicts the site layout from above, showing sensor placement.

Ground-Level View: Shows the site layout from ground level, illustrating sensor placement.

Safety Device Types:

• A Non-contact sensor: When a non-contact sensor is used, it is recommended to permanently fix the sensor under the path of the barrier arm. Recommended to mount sensor between 21"-27" above grade. WARNING: Never use a non-contact sensor, microwave sensor OR any motion activated detection device to provide a close command to the barrier arm operator. This can be dangerous and is not recommended.
• B Contact sensor: When a contact sensor is used, it should be mounted to the bottom of the barrier arm in the existing channel. A wireless edge sensor is the only contact sensor supported by this system. This system does not support a hardwired edge sensor.

Operator and Arm Installation Options

NOTE: The Barrier Arm is not included and must be purchased separately. See "Accessories" on page 57.

The barrier arm gate operator may be installed with right-hand or left-hand operation. The barrier arm may be installed with or without the Arm Breakaway setup.

CAUTION: If the Arm Breakaway setup is not used, damage to the operator may occur.

NOTE: The barrier must be fully open (arm/bracket in the vertical position) before modifying the counterbalance spring assembly.

Handing Options

The barrier arm gate operator may be installed with right-hand or left-hand operation. See the image to determine the handing in relation to the operator when facing the opening of the cabinet.

Left Handing: Diagram showing operator configuration for left-hand installation.

Right Handing: Diagram showing operator configuration for right-hand installation.

Counterbalance Springs Direction

The arrow of each installed spring must point in the direction of the arm in the closed position for left- or right-handing. The counterbalance spring assembly comes from the factory in the right-handed configuration.

Reinstall all springs in the proper direction when the handing is changed. For instructions, see "Reverse the Spring Handing" on page 16.

WARNING: FOLLOW THE STEPS OUTLINED IN "REMOVING SPRING TENSION" TO ENSURE THAT ALL TENSION IS RELEASED FROM SPRINGS PRIOR TO REMOVING BOLTS, OR THE END PLATE.

Removing Spring Tension

ATTENTION: The steps below must be used to safely remove springs from a PBG, CBG, or IBG operator. They allow the spring assembly to disengage from the gearbox while it is still mounted in place.

1. Locate the three bolts that attach the spring assembly to the gearbox. Using a socket wrench and extension to avoid accidental contact with the loaded springs inside the cabinet enclosure, loosen each screw by 3 full rotations only. Do NOT fully remove these bolts yet.
2. Use a flathead screwdriver or pry bar around the edges of the spring assembly to disengage it from the gearbox, avoiding contact with the springs and center hub. Do not use hands or body to release tension.
3. Verify the springs are loose before removing the three bolts completely. The shaft of the spring assembly should be able to move a few degrees by hand if the springs are disengaged.

NOTE: The Handing of the Barrier Arm may be changed from right-hand to left-hand operation, and vice versa.

ARM SWINGAWAY SETUP (OPTIONAL)
