Figure 6-12.
Refer to Figure 6-12 to help plan the most appropriate placement of the edge sensors being installed. For
sliding gates, one or more contact sensors (edge sensors) must be located at the leading edge, trailing edge and
post-mounted both inside and outside of the sliding gate. Three-sided detectors are ideal for slide gates. If the
clearance of the gate is 6" (15cm) or more above the road, then an edge sensor must be mounted on the bottom
edge. Underwriters Laboratories requires that any contact sensor used as an external entrapment protection
device, must be laboratory tested to, and recognized by, the UL 325 Standard.
Drill holes through the edge's mounting channel and through the surface that each gate edge is to be mounted.
Securely fasten every edge sensor. Make sure sensors extend to within 6" (15cm) of the pavement on the
leading edge of the gate.
