In the above system diagram the door interface is made by an externally installed S-ART unit. This S-ART is
connected via the build-in S-ART controller. A very simple installation can be made if the door-signals and the
reader are not available at the same place. Max. 15 S-ART's can be connected directly to the reader. In this
solution set/unset signals to and from a "non-THOR" intrusion system can also be integrated in the access
functions.
An external 24V or 12V power supply can be used or the standard THOR power supply. Also a separate printer
interface can be installed directly to the reader on the RS-485 bus. The reader does in this case not work in
stand-alone mode anymore.
Minimum one 90T S102 S-ART is needed per configuration where the two inputs are used for the door contact
and exit push-button and the relay output is used to control the striking plate.
