Boom Barrier Ground Sense and Loop Detector Installation Method

The inductive-loop detector system is composed of one or more wire loops embedded in the pavement (the sensing element), a splice between the lead-in wire and the lead-in cable in the pull box, lead-in cable (usually in a conduit) connecting to the terminal strip in the controller cabinet, cable from the terminal strip to the inductive-loop electronics unit, and finally, the electronics unit, itself.

INSTALLATION TECHNIQUES

Inductive-loop detectors are installed in asphalt or portland cement concrete pavements using the process illustrated and described by the steps below:

• Cutting a slot.
• Cleaning and drying the slot.
• Laying in the inductive-loop detector wire.
• Sealing the sawcut.
• Connecting the wire to the lead-in cable.
• Connecting the cable to the terminal strip in the cabinet.
• Ensuring the harness connects the terminal strip to the electronics unit.
