Installation: Inductive Loops
WARNING – Consult the installation instructions from the loop detector manufacturer. The follow-
ing statements are provided as a guide but different requirements may be required by the vehicular
loop detector manufacturer.
Inductive Loops Installation:
Safety loops allows the gate to stay open when vehicles are obstructing the gate path.
If the gate is longer than the vehicles that pass through it a center loop is recommended and should
be installed. A center loop prevents the gate from closing when a vehicle is between the safety loops.
Safety loops are required when using a center loop. See Loop Wiring.
