This is a basic interlock door system with an emergency exit function but
without a central bus master (stand-alone).
Function
As soon as a door is temporarily released or disengaged, the correspond-
ing opposite door (several doors also possible) is blocked and thus can-
not be opened.
If the disengaged door is not opened before the pre-set temporary re-
lease interval has elapsed, it is automatically locked again.
Note
The escape route is assured using a fail-unlocked system, i.e. in the event
of a power failure, or unlocking by a fire alarm system or an EMERGENCY-
OPEN switch, locking elements are disengaged and all doors can be
opened at the same time.
