OVERVIEW
This set up opens the magnetic doorlock using the inside iclock 680 and the outside iclock 680.
The iclock 680 inside gives supply to the magnetic doorlock. It can open the magnetic doorlock through the users finger prints and through the exit push button.
The iclock 680 outside can also open the magnetic doorlock by triggering the push button of the inside iclock 680 using the relay switch in series with the normally close push button.
The relay switch is powered by iclock 680 outside through the NC connection. This will give a close circuit continuity of the relay switch output at normal operation.
When the iclock 680 outside detects finger prints of the user then it will cut off the power of the relay which will give open circuit to the normally close push button of the inside iclock 680 and this will opens the magnetic doorlock.
