Functions and meaning

Self-locking system

The electric security lock 809 locks automatically. If it is a door lock with auto-
matic locking, the close door is always locked.
1

Functional principle

2
When closing the door the extended latch (Pic. 5 – 2) is pushed on the striking
plate. If the latch is activated, then the control latch (– 1) can also be activated.
If the door is completely closed the latch slides into the latch opening in the
3
striking plate and is extended again such that the control latch remains pressed
in.
If the latch is extended and the control latch is simultaneously pressed in, the
lock (– 3) is released and extended by a spring mechanism.This mechanism
prevents the deadbolt from extending when the door is opened during normal
use.

Profile cylinder (locking cylinder)

The lock is unlocked by the profile cylinder. For production versions with electronic monitoring of the
profile cylinder (Tab. 5), the profile cylinder is a signal transmitter for superordinate control systems
("Status messages for the control system", page 46). Locking with the profile cylinder is not necessary and
not possible. The profile cylinder has an internal stop collar so that it cannot be fully turned.
The key must be pulled out in normal operation.

Unlocking and locking

The locked security lock 809 can be unlocked in various ways depending on the function (with and without

escape door function).

Variant with escape door function (panic function E, transmission function)

The locked security lock 809 with escape door function is unlocked in the following situations:
· the door handle is operated from inside;
· the latch and bolt are retracted from outside with the actuation of the profile cylinder,
· by means of an electrical trigger action ("Access control", page 46).
When the doors are closed, the bolts automatically extend.

Variant without escape door function (transmission function)

The locked security lock 809 without escape door function is unlocked in the following situations:
· the latch and bolt are retracted with the actuation of the profile cylinder,
· by means of an electrical trigger action ("Access control", page 46).
When the doors are closed, the bolts automatically extend.
Escape door function
In general: A door with escape door lock can always be opened with the door handle from the inside, even
if it is locked.
