DAK-2ULTMVP Overview

The DAK-2ULTMVP drive-thru alert kit provides an audio and visual indication to team members that need to know when a customer’s vehicle has pulled into the drive-thru lane. This system can be used in a wide variety of drive-thru applications requiring 2 detection zones, including fast-food restaurants, banking, and car wash.

The panel inside the junction box will have the transformer and ULT-MVP vehicle detectors mounted and prewired. Terminal blocks inside the panel will be available for easy connection of incoming power (120 VAC) and wire connections to the PR-46 loops and LED beacon. All of the vehicle detectors and the LED beacon will be preprogrammed.

Features of Our Drive-Thru Alert Kit

The DAK-2ULTMVP is a complete system for detecting vehicles and notifying staff for applications requiring dual-zone detection.

  • The ULT-MVP is a multi-voltage vehicle detector that will automatically adjust from 12 VDC up to 240 VAC to fit any installation. The ULTRAMETER™ display indicates the appropriate sensitivity setting to detect a vehicle near the loop. Ten sensitivity settings allow for fine adjustment of the detection level, while four frequency settings provide flexibility in preventing crosstalk in multi-loop applications. The ULT-MVP provides two relay outputs – one for indicating vehicle presence and a second for loop fault, pulse on entry/exit, or DETECT-ON-STOP™. DOS® allows detection only when a vehicle has come to a complete stop on the loop. This EMX exclusive feature ignores cross traffic in tight spaces.
  • The PR-46-100 is a ready-to-use, preformed loop with a 100-foot lead that can be shortened or spliced to extend as needed. The loop is housed in rugged and flexible 0.26” diameter thermoplastic rubber tubing and provides built-in lightning protection. It is suitable for all installations – saw cut, concrete, and tar.
  • The SLM500B is a LED beacon and sounder with three separate levels of alarm. Channel 1 includes a simulated strobe (triple flash). Channel 2 adds an audible tone (32 options included) to the simulated strobe effect. Channel 3 includes a steady light and a second, unique tone (32 options included) for a total of 64 unique tones. The volume of the tone is adjustable from 65-105 dBa.
