DAK-USVD Overview

The ultrasonic drive-thru alert kit is comprised of two components: the CHIME-100 sound module, which provides an audio indication to team members, and the USVD-4X ultrasonic vehicle detector, which detects the presence of a vehicle. This system can be used in a wide variety of drive-thru applications, including parking, access control, car wash, banking, and fast food.

Chime 100

The CHIME-100 provides an audible chime when a vehicle first pulls in front of the vehicle detector. It is a compact, audio alert device designed for loud work environments. The CHIME-100 has adjustable volume control and can reach volumes of 100 dBA at 5 ft away making it easy to hear in noisy areas. It is easy to install with two mounting tabs and includes 25 ft of durable cable for connection to the USVD-4X. The CHIME-100 also features an output relay for daisy-chaining additional electronics and 6 melodies to choose from.


The USVD-4X is mounted on a post, order box, or the side of a building and aimed at the desired location for vehicle detection. No additional setup or functional adjustments are necessary – unlike other vehicle detection systems. Also unlike other technologies, the USVD-4X does not require the installation of an inductive loop in the pavement. The detection head consists of 4 ultrasonic transducers that connect to the internal microprocessor-based control board. The USVD-4X “scans” the expected location for a vehicle and activates its output upon detection of a vehicle. It operates on 2-24 VDC/AC and provides two Form C relay contacts for vehicle presence detection, as well as Pulse on Entry, Pulse on Exit, or both.
