4. At each lane where video is in use, connect a Model 1523 Video Add-on to the Video
port on the 1520 or connect standard 75-ohm NTSC cameras and monitors to the 1520
video jacks. Plug power supplies into the Power jacks.
5. Plug the lane power supplies into a source of 100-260 volts AC. An adapter cable is
provided with the 1520 to allow power to be drawn from a terminal block in a pneumatic
unit. If AC power is not available on the customer end, a power supply may be located
indoors and its output leads extended using a suitable gauge of wire as shown at right.
To power multiple lane units, it may be convenient to use an 805-016 three amp power
supply. Call Audio Authority for details.
Installing Model 1520 Lane Stations
Lane Stations may be placed at the customer end of a drive-up or walk-up intercom system. The Model 1520 is the
basic Lane Station unit for installations where the microphone, speaker (plus video screen and camera, if used) are
mounted separately. The Model 1522 is a Video Lane Station, including all of the features of the 1520 plus microphone,
speaker, camera and video screen mounted inside one enclosure. The Model 1523 Video Add-on must be used with a
1520, and contains only the camera and video screen.
1. Install the Model 1520 Lane Station in each deal drawer or pneumatic unit on the customer end, using the screws
provided. If AC power is not available at the customer end, see Step 5.
2. Install the lane microphones and speakers if they are not already installed. Mount the speakers in the grilles
provided in the drive-up units. Peel the backing from the microphone shrouds and adhere them directly centered
over a 1/8” hole drilled in the faces of the customer units. At each station, place the microphone and speaker as
far apart as practical, while centering the microphone to receive customer speech. Install Teller Call push-button
switches, if needed.
3. Connect the Microphones, Speakers and Teller Call switches to the 1520 terminal blocks. Strip all wires 1/4” long.
If pneumatic blower muting is desired, connect the DRY blower contacts to the corresponding points on the terminal
blocks, using small (about 22 AWG) wire. If trafc sensing devices or remote-controlled security doors are in use,
connect them as indicated.
