SAFETY Safety Installation Information 1. Vehicular gate systems provide convenience and security. Gate systems 9. The Stop and/or Reset (if provided separately) must be located in the are comprised of many component parts. The gate operator is only one line-of-sight of the gate. Activation of the reset control shall not cause component. Each gate system is specifically designed for an individual the operator to start. application. 10. A minimum of two (2) WARNING SIGNS shall be installed in the area 2. Gate operating system designers, installers and users must take into of the gate. Each placard is to be visible by persons located on the side account the possible hazards associated with each individual of the gate on which the placard is installed. application. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. Gate systems design and installation must reduce public exposure to potential hazards. 11. 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. See Install Entrapment 3. A gate operator can create high levels of force in its function as a Protection section. component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include: l Edges Sensors (contact) 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. l Guards for Exposed Rollers c. One or more non-contact sensors shall be located where the risk of l Photoelectric Sensors entrapment or obstruction exists, such as the perimeter reachable l Screen Mesh by a moving gate or barrier. l Vertical Posts l Instructional and Precautionary Signage 4. 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 6 feet (1.8 m) above the ground to prevent a 2-1/4 inches (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. 12. For a gate operator utilizing a contact sensor such as an edge sensor: a. 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. b. 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. c. A wireless device such as 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 device shall function under the intended end-use conditions. 5. 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. 6. 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. 7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. 8. Permanently mounted access controls intended for users to activate, must be located at least 6 feet (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. Exception: Emergency access controls only accessible by authorized personnel (e.g. fire, police) may be placed at any location in the line-of-sight of the gate. 4
