Connection example 3
Door lock with a two-door system and two code locks
The two-door system is used for access to rooms where only one door may be opened
at a time (e.g. access to clean rooms). The doors can be operated from outside by the
code lock and from inside by the contact.
The green LED "DOOR" shows the status (door opened).
Connect an optional magnetic switch to each code lock (DOOR SENS) to monitor the
open or closed state of the doors. If door 1 is open then door 2 is locked and vice-versa.
