Door contact
The door contact is actuated by the striking plate, thereby reporting the door status.
With use of the OneSystem IO module N5950
If the electric security lock 809N is connected to a OneSystem IO module N5950, the output signal of the door
contact is evaluated. A door closed status message is issued.
Fault message
If the latch bolt is extended while the control latch is pushed in, but the door contact has not been actu-
ated by the striking plate, there is a fault. This fault is shown on the optional OneSystem IO module N5950.
The electric security lock 809N has an automatic locking function. In the case
of door locks with automatic locking, the closed door is always locked.
Functional principle
The electric security lock 809N is equipped with a door contact (Fig. 4 –
and „Explanation of terms",
plate while the door is closed.
When the door is closed, the latch bolt (Fig. 4 –
plate is pushed inwards. If the latch bolt is pushed in, then the control latch
(–

) can also be pushed in. If the door is completely closed, the latch bolt
slides into the latch opening in the locking plate and is thus extended again,
while the control latch remains pushed-in.
If the latch bolt is extended while the control latch is pushed in, the dead-
bolt (–

) is released and extended by means of a spring mechanism. This
sequence control system prevents the deadbolt from extending when the
door is opened during normal use.
The locking process is only complete once the latch bolt and bolt have been
extended and the door contact is actuated. The lock is locked.
