ACCESSORY CONNECTIONS
1.
Prevent sharp corners in the geometry of the loop sensor.
2.
Install the appropriate number of turns for your loop geometry based on the loop
perimeter. Use Table C (below) as a guide.
3.
Use XLP (cross-linked-polyethylene) type of wire. This wire reduces the effects of
moisture and other environmental events in altering the functionality of the vehicular
loop detector.
4.
Twist the lead wire at least 6 turns per foot.
5.
Use BACKER-ROD to minimize damage to the loop detector wire prior to using the
sealant.
6.
Place the loop detector wire and adjust the sensitivity of the vehicular loop detector
unit in a way to minimize the effects of the gate over the loop detector wire.
! IMPORTANT! Some of the following parameters may affect the proper functionality of the
vehicular loop detector.
Consult the manufacturer of the vehicular loop detector and/or loop wire.
• Gate size
• Number of turns in the loop sensor wire
• Distance of the loop sensor wire to the gate at either at the open or close position
Dimension “A” - 5’ for Single Gate
