3M™ Drive-Thru Systems G5 Basestation Model G5B1
Installation Manual
• Flashing green, single flash every 1.5 seconds—indicates an open loop
fault (a wire is disconnected or severed).
• Flashing green, double flash every 1.5 seconds—indicates a shorted
loop fault (the loop wires are making unwanted contact at some point
before they reach the loop detector).
• Steady red—indicates that power is applied and a vehicle is currently
detected.
Note:
The vehicle detector fails closed; therefore if there is a fault, the system
assumes that there is a vehicle present.
Greeter Alert Trigger Inputs
The Greeter functionality is built into the G5 Basestation Model G5B1. In
addition to playing back a Greet message to the customer at the Order Point
and/or playing a Reminder message at a scheduled time of day, the user can also
program the system to playback an Alert message whenever an external event
occurs, such as Opening the Back Door or Opening the Refrigerator.
The installer can configure any of the 16 GPIOs on the G5 Basestation Model
G5B1 as ALERT Message Trigger Inputs. For example, if you chose to wire the
back door sensor to GPIO1 and GND, any time these two pins are shorted, the
ALERT message assigned to this input (such as Back Door Open) will play on
each headset configured to play the ALERT Message. See Figure 15 for an
example.
