GETTING STARTED WITH SWING AND SLIDE GATE OPERATORS. Always design, install and maintain safe gate access systems in accordance with UL 325 & ASTM F2200 standards. • Only install the operator on gates used for vehicular traffic. • A separate pedestrian entry/exit must be clearly visible to promote pedestrian usage and located so pedestrians do not come in contact with the vehicular gate while it is moving. • Install two independent† entrapment protection devices protecting each entrapment zone. • Pickets of a slide gate must be designed or screened to prevent persons from reaching through, or passing through a gate. • Every Installation is unique. It is the responsibility of the installer to ensure all entrapment zones are protected with a minimum of two independent† entrapment protection devices. • A slide gate operator will only operate with a minimum of two independent monitored entrapment protection devices installed in each direction, two in the open direction and two in the closed direction†. • A swing gate operator will only operate with a minimum of two independent monitored entrapment protection devices installed in either the open or closed direction. If no entrapment zone exists in the other direction, only one means of entrapment protection is required in that direction†. †Independent the same type of device shall not be utilized for both entrapment SLIDE GATE SITE LAYOUT GUIDELINES FIGURE 1 protection devices. SLIDE GATE SPACING GUIDELINES FIGURE 2 PUBLIC SIDE WARNING Be sure to place the WARNING signs on both sides of the gate in clear view. For your records, take a photograph of the completed installation site. Mount access control devices at least 6 ft (1.8 m) beyond the gate. 6 ft (1.8 m) minimum Pedestrian gate located near the slide gate. Make sure a separate walkthrough entrance is available and its pedestrian path is clearly designated. Slide Gate Gaps A gap, measured in the horizontal plane parallel to the roadway, between a fixed stationary object nearest the roadway (such as a gate support post) and the gate frame when the gate is in either the fully open position or the fully closed position, shall not exceed 2 ¼ in.. Exception: All other fixed stationary objects greater than 16 in. from the gate frame shall not be required to comply with this section. Any gap must be Interior posts, Guide posts protected. Install safety device to protect entrapment zone. Non-pinch Gap between vertical bars must be less than 2¼" (57 mm) rollers (2x) Edge sensor on Trailing Edge of gate V track (gate rail) Physical stop Photo eye Emitter or Reflector (Close direction) ZONE Edge sensor on Leading Edge of gate Edge sensor (Draw-in zone) SLIDE GATE OPENINGS GUIDELINES FIGURE 3 Openings of a horizontal slide gate must be smaller than 2 1/4" or else be guarded or screened. These design rules apply to both the moving gate as well as the portion of adjacent fence that the gate covers in the open position. See Illustrations below.

Photo eye (Receiver) SECURE SIDE NOTE: Any gap larger than 2¼" (57 mm) between gate and fixed objects must be protected. Install edge sensors where gap between post and gate creates an entrapment zone.

SWING GATE SITE LAYOUT GUIDELINES FIGURE 4 PUBLIC SIDE WARNING Be sure to place the WARNING signs on both sides of the access point in clear view of vehicles. For your records, take a photograph of the completed installation site. Photo eye (public side) Mount access control devices at least 6 ft (1.8 m) beyond the gate. Photo eye (public side) Photo eyes Gate Frame and Adjacent Fence Area 6 ft. minimum For gaps (xxx) equal to or larger than 2 1/4", a wire mesh screen must be applied to the gate. Wire mesh screen openings must be smaller than 2 1/4". The minimum height of wire mesh screen: 6 ft. above grade. FIGURE 5 Earth ground ENTRAPMENT Curb Pedestrian gate located near the swing gate. Make sure a separate walk-through entrance is available and its pedestrian path is clearly designated. ZONE Edge sensor View A Cross Section ENTRAPMENT Curb A ENTRAPMENT ZONE SECURE SIDE Reflector for Photo Eye **Swing Gate Entrapment Zones: Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8m (6 ft) above grade. Such locations occur if during any point in travel: a) The gap between the bottom of a moving gate and the ground is greater than 101.6mm (4 in) and less than 406mm (16 in); or b) The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6mm (4 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16 in) (examples are walls, curbs, berms, or other immovable objects). The above examples are two of many installation possibilities and are for illustration purposes only. See device and operator manuals for complete instruction. Visit DAMSA.com for more information. Definitions Entrapment: The condition when a person is caught or held in a position that increases the risk of injury. Slide Gate Entrapment Zones: An entrapment zone exists if at any point during travel, the gap between the moving gate and fixed counter opposing edges or surfaces is less than 406 mm (16") in a location up to 1.8 m (6ft.) above grade.
