Above schematics is correct and works fine.
However not really.
There is a safety issue.
People who don't close the door with their key (deadbolt) leave the house vulnerable for intruders.
At night when nobody is arround, you unscrew the VTO2202 from its housing.
The tamper switch goes of and the VTO2202 in your hand starts sounding.
Who cares ! Nobody is in the street tonight.
The VTH2421 starts sounding in the house too.
Who cares ! Nobody is in the house tonight.
Now hit the red wire against the green wire and the door will open.
You're inside Master Thief.
Solution
Use the DEE1010B RS485 remote door controller.
Do not wire the NC and Common on the VTO2202 Door Station.
Allow the VT02202 Door Station to communicate only through the RS485 bus.
Hit orange to blue. Nothing will happen. You Moron Thief.
