• Contact sensors may be located at the leading edge, trailing edge, and post mounted both
inside and outside of the vehicular sliding gate. Additional contact sensors may be added for
additional protection where an entrapment zone may exist.
• Hardwired contact sensors must be located and wiring arranged so that the communication
between the sensor and the gate operator is not subjected to mechanical damage.
