Loop detector

This system is installed at about 6 feet from the door on the inside of the building (concrete slab) or on the outside (asphalt). Metallic objects traveling over the loop detector affect the magnetic field of the loop. The detector senses this change and gives a signal to open or close the door. Must be installed by a qualified electrician.
