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 Photoelectric Sensors c. One or more non-contact sensors shall be located where the risk of l Vertical Posts entrapment or obstruction exists, such as the perimeter reachable l Instructional and Precautionary Signage by a moving gate or barrier. 4. Install the gate operator only when: 12. For a gate operator utilizing a contact sensor such as an edge sensor: a. The operator is appropriate for the construction and the usage class of the gate. a. One or more contact sensors shall be located where the risk of entrapment or obstruction exists. b. All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers. 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.

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 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. d. 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 4 inches (10.1 cm) but less than 16 inches (406 mm) above the ground at any point in its arc of travel, one or more contact sensors shall be located on the bottom edge. the gate and where the user is prevented from reaching over, under, around or through the gate to operate the controls.
