Installation Manual
The following diagram shows the wiring configuration between a base station
and the components of a single drive thru. In systems with two base stations,
use this wiring diagram for each of the stations, then see “Base Station to Base
Station Wiring,” Page 21.
Note:
Vehicle Detector 1 (VEHDET.1) must always be used for proper base station
operation. Vehicle detectors 2 and 3 (or any integral detectors installed with
optional modules) can be used at your discretion.
