Installation Instructions G5 - Revision C, September 2019
3M™ Drive-Thru System Model G5
Vehicle Detectors
There are two available installation slots at the bottom of the Basestation for vehicle detector boards, one for each lane of drive-thru
operation. Once installed, each detector board must be configured for sensitivity, delay, and pulse/presence detection.
• Sensitivity – there are four available sensitivity settings: low, medium low, medium high, and high. Setting a high sensitivity
increases vehicle detection but also increases the likelihood of false detection (e.g., unwanted detection of vehicles not in the
drive-thru).
• Delay – you can enable a two-second delay that waits until a vehicle has been detected for two seconds before the detection alert
is triggered. Enabling the delay prevents the detection alert when cars drive over the detector without stopping to order.
• Presence/pulse setting – typical vehicle detectors detect the presence of a vehicle. They remain active for as long as a vehicle is
in range of the detector; however, there are some types (e.g., air hoses) that only trigger when a vehicle drives over them with no
further feedback to indicate whether the vehicle remains. The fourth dip switch must be set to the type of detector you have.
Perform the following procedure to install and configure a vehicle detector board:
• Ensure that the Basestation is unplugged.
• Remove the Basestation cover. See “Removing and Replacing the Cover” on page 15.
• Align the bottom of the vehicle detector board with the installation slot.
• Slide the top edge of the board between the back of the Basestation and the two raised tabs.
• Install and gently tighten the screw.
• Carefully install the three wires between the vehicle detector board and the Basestation board (see Figure 19). The left-to-right pin
order is the same on both boards: the left pin on one corresponds to the left pin on the other.
• Configure the dip switches according to the table on the circuit board and your needs (see Figure 20).
