Intercom Connections
Note: If there is a separate Incoming Volume Control assembly installed onto the old system,
that Volume Control assembly must be removed.
There is an intercom board (base audio board) located at each of the drive-thru lanes. Note that
the base audio must be calibrated for BEAM use. There will be a label on the base audio board
specifying beam calibration. This board is connected to the telephone interface via standard
CAT 5 wiring. Remote lanes have a Microfit connector for improved weather resistance. First
lanes use a RJ45 plug which is terminated 568B. Each remote intercom board has a LED, which
indicates that it is receiving power. The audio level adjustments on the base audio board are
sealed after they are calibrated. The audio levels are adjusted inside of the interface.
The intercom audio board for the 64” All-In-One window with the E.F. Bavis counter system is
attached to the black laminated or Stainless Steel filler panel under the transaction drawer. For
other window/drawer installations, it will be inside of a 2-1/8” x 3-1/4” x 5-1/4”, Stainless Steel
enclosure. The intercom audio board for the TransTrax is located inside a weatherproof
enclosure, on the customer speaker panel, of the customer unit located on the outside island.
The base audio component connections are as follows: Plug J1 is for the speaker connection.
The connector is a 3-position with positions 1 & 3 being the speaker. For the outside board, plug
J2 is an 8-position Microfit, for the inside board, plug J2 is an 8-position RJ45. Plug J3 is for the
call button connections. The connector is a 4-position with positions 2 & 3 being the button.
Note that positions 1 & 4 are 19vdc power with position 4 being positive. Plug J4 is for the
microphone connection. This connector is a 2-position.
Please see page 11 for an overall wiring diagram of the intercom section.
It is recommended to install the RJ45 connector directly onto the end of the CAT5 cable for the
drive-thru lane. For situations where tooling is not available to attach the RJ45 to the end of the
CAT5 cable for the remote lane(s), we have included a Cat5 Audio Connection Kit, (P/N
22316991) that can be added onto the cable for plug-in connection capability.
