The SYSLM4 magnetic loop together with metal mass detector model FJCD621 is a security device that prevents the barrier arm to go down if a vehicle is beneath it. It also sends the order to close the barrier once the vehicle has passed.
Note: The SYSLM6, SYSLM4 loops and the FJCD621 detector are designed for applications with standard vehicles and vans. For applications with trailers, trucks, and similar, please contact our Engineering Department.
