2.1 Sample Normal Timing Sequence
The Main Console’s interface with the customer-furnished Intercom and Vehicle Detector allows the Timer
to detect a vehicle that has been greeted via Intercom upon arrival at the
Menu Board. Window Loops allow the Timer to detect the car’s arrival at and departure from
the cashier and service window and/or other detection points. For simplicity, the following sequence of
events assumes that there are Loops at the Cashier Window and Pick-Up Window
(See Figure 1)
:
Event 1. A vehicle arrives at the Menu Board where the Loop detects its presence. A
VEHICLE
PRESENCE SIGNAL
is sent by the Vehicle Detector to the Main Console which starts the timing
sequence.
Event 2. An employee keys the Intercom microphone to greet the cust
omer. The employee’s voice
generates a GREET CANCEL signal that is sent to the Main Console which records the time as the
GREET
time.
Event 3. When the vehicle departs from the Menu Board deactivating the Menu Board Loop the
VEHICLE PRESENCE SIGNAL discontinues. The Main Console interprets the time as the
MENU
time.
Event 4. When the vehicle arrives at the Cashier Loop, a VEHICLE PRESENCE SIGNAL is sent to the
Main Console. The Main Console interprets the time as
WAIT
time.
Event 5. When the vehicle departs from the cashier's window deactivating the Cashier Loop the
VEHICLE PRESENCE SIGNAL discontinues. The Main Console interprets the time as the
CASHIER
time.
Event 6. When the vehicle arrives at the Pick-Up Loop, a VEHICLE PRESENCE SIGNAL is sent to the
Main Console. The Main Console interprets the time as
WAIT
time.
Event 7. When the vehicle departs from the service window, deactivating the Pick-Up Loop, the
VEHICLE PRESENCE SIGNAL discontinues. The Main Console interprets the time as
PICK-UP
time.
Additionally the Main Console interprets the time as this customer's
TOTAL
Line Time.

2.2 Multiple Vehicles
The Timer is capable of keeping track of up to 16 vehicles moving simultaneously through each drive-thru
lane. The Timer can track the progress of each vehicle independently, accurately noting when each car
moves onto or off a vehicle detection zone.
