A wire loop is embedded across the entrance or exit of the driveway surface at a depth of approx. 1 1/2" where it is not subjected to traffic wear and tear or the elements. A socket base interconnects the driveway loop and the plug-in 625X detector which can be installed in a weatherproof housing up 600 ft. away from the drive loop. Detection is achieved by means of a differential oscillator and a relay unit which react when a vehicle passes over the loop. This causes the operator's reversing contactor to energize and to open door/gate/barrier. For best detection, the minimum distance of the driveway loop in the direction of travel should be 6 ft. (1.8M). The effective height of detection of the 625X is roughly half the dimension of the roadway loop. Loops shorter than 6 ft. (1.8M) may result in the non-detection of some high bed vehicles. The driveway-embedded portion of the loop is made of multistrand single conductor No. 14AWG wire (loop wires not included). For detailed installation manual, consult Doorlec Corporation.
