Installation Install the Base Station Choose a Location Generally, the base station should be located centrally, and close to the order takers. However there are several important guidelines that must be followed to reduce the risk of problems. Follow the guidelines to ensure that the base station(s) can communicate with headsets in any foreseeable location: • • • • • • Do not assume that the location of an old base station is suitable for a new base station.
Installation • Lift the cover upward and away. The display and keypad remain with the base, not with the cover. To replace the base station cover: • • • Verify there are no obstructions (tools, etc.) in the way of the cover being closed. Align the top edge of the cover with the base. Swing the bottom half of the cover down into place and gently push it against the base until it locks into place. Tighten the two screws located at the bottom of the cover.
Installation Note: The steps below assume that all of the communication cabling has been prepared and is available at the base station. If not, see “ Base Station to Component Wiring,” page 25. • • • Follow local best practices and any applicable regulations to route the cables into the base station cabinet’s top, sides, or back (through the wall) as neatly as possible. Do not route power supply wiring with communication wiring in the same conduit. Attach all cables to their appropriate terminals.
Installation Figure 7 Terminal Label Definition and Connection Information GENERAL PURPOSE INPUT / OUTPUTs (GPIOs): 16 configurable logical Inputs and Outputs. All Inputs and Outputs are Active Low and are factory set to the following signals. You can reassign any of these GPIOs to output or take as input a different signal. The GPIOs 15 and 16 are logically mapped to the 1_GRT_CNL and 2_GRT_CNL of Lan1 and Lane2 connectors respectively. You will have to use the GND0 or GND1 from the GPIO terminal block.
Installation GPIO72 Unused GND0 Ground GND1 Ground GPIO8 VEH_APP_1 GPIO9 VEH_APP_2 GPIO10 Unused GND1 Ground GPIO11 TALK_1 GPIO12 PAGE_1 GPIO13 TALK_2 GPIO14 PAGE_2 GND1 Ground AUXILLIARY RELAYS: Two SPDT Relays corresponding to the two Vehicle Detectors. Allows for integration of 3rd party accessories. Alternatively, these terminals can be configured via Digital IO Setup in the System Menu to provide the Active Low TALK, PAGE and/or Greet Cancel signal.
Installation 2_SPKR_OUT+ Positive phase order point speaker for Lane2 2_SPKR_OUT- Negative phase order point speaker for Lane2 2_GRT_CNL (GPIO16) Active low talk.

Installation Figure 8 Figure 9 and Figure 9 and Figure 9 shows the wiring configuration between a base station and the components of a dual lane drive thru. If the installation is for a single lane operation, refer to Lane1 wiring in the illustration above Note: Vehicle Detector 1 (D1_12V, D1_GND and D1_DET) must always be used for Lane 1 base station operation and Vehicle Detector 2 (D2_12V, D2_GND and D2_DET) must always be used for Lane 2 base station April 24 2015 – Revision 1.
Installation Figure 9 Figure 10 Auxiliary Detector Relays You can use the base station’s vehicle detection circuits to operate an auxiliary relay for a number of convenient uses (typically an external greeter or timer module, but could also be used to operate a vehicle approach chime or other device that is independent of the intercom system). Virtually any device that can be activated by opening or closing a switch can be linked to vehicle detection.
Installation Simple Circuit Example Figure 11 shows a simple DC circuit (a light and DC power supply) being operated by the auxiliary relay. To make the light turn on when a vehicle is detected on Lane1, terminals R1_COM and R1_NO (normally open) would be used. To make the light turn off when a vehicle is detected Lane1, terminals R1_COM and R1_NC (normally closed) would be used .
Installation Note: GPIO15 and GPIO16 are located in the Lane1 and Lane2 Order Point Connectors. Figure 12 Installing Accessory Boards in the Base Station Accessory boards include up to two vehicle detectors for a dual lane operation and a backup module. They must be installed into the base station according to the following procedures. 3M™ Drive-Thru Systems G5 Basestation Model G5B1 Installation Manual April 24 2015 – Revision 1.
Installation Vehicle Detectors There are two available installation slots at the bottom of the base station 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.
Installation • Configure the dip switches according to the table on the circuit board and your needs (see Figure 14). • • • Figure 13 • • • Adjust the sensitivity of vehicle detection by manipulating the top two dip switches. Enable or disable a two second detection delay by manipulating the third switch Choose presence or pulse detection by manipulating the fourth switch.
Installation • • • 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.
Installation Power Up After installation is complete, you can power up the system by plugging in the base station transformer. Run Mode Menu When the system is powered up and functioning normally, the Run mode menu appears on the display. Figure 16 shows the Run mode menu.
