USVD-4X™
Ultrasonic Vehicle Detector
Instruction Manual
The USVD-4X uses ultrasonic to reliably detect the presence of a vehicle in a wide variety of drive-thru
applications including parking, access control, car wash, banking and fast food. The USVD-4X does not
require the installation of an induction loop. It is simply mounted on a post and aimed at the desired
location of detection. No additional set-up or functional adjustments are needed. The detection head
consists of 4 ultrasonic transducers that scan the expected location for a vehicle and activates an output.
Cautions and Warnings
