2.3.2 CONTACT SENSORS
• Disconnect power to the gate operator before installing the contact sensors.
• Connect the contact sensors as shown below to the auxiliary terminal strip. Note that all
commons connect to main terminal 12.
• Contact sensors must 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.
• Inputs from sensing edges/receiver to circuit board are NORMALLY OPEN.
• Diagram does not show power wiring to RF receiver.
