Vehicle Detectors
There are three available installation slots at the top of the base station for
vehicle detector boards. 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 base station is unplugged.
•
Remove the base station cover, see page 19.
•
Align the bottom of the vehicle detector board with the installation slot.
•
Slide the top edge of the board between the back of the base station and
the two raised tabs.
•
Install and gently tighten the screw.
•
Carefully install the three wires between the vehicle detector board and
the base station board (see Figure 14). 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 15).
