Auxiliary Detector Relays
Figure 15.
You can use the basestation’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.
The relay terminals are numbered according to the vehicle detector they are paired with. For example, R_NC, R1_NO,
and R1_COM are paired with Vehicle Detector 1.
There are several other sources from which to obtain the vehicle detector relay signals. They are:
1.
The 1_NO and 1_COM from Lane1 connector and 2_NO and 2_COM from the Lane2 Connector.
2.
The 16 logical GPIOs can be configured via the basestation’s System Menu, to pair up with the vehicle
detectors for Lane1 or Lane2.
