External door opener button and ringer stop
contact
If the door is opened by an external door opener button, the following will
occur:
– The door is opened.
– The ringer is ended immediately.
– An existing door conversation is ended after the configured time (End
when door opens).
The same sequence can be achieved by manually opening the door when
a ringer stop contact is installed. This contact is connected in series with the
door opener and must be closed with the door closed and opened when the
door is opened.
