Area Change Control; Operation In Connection With An Additional Escape Door Control System - effeff 809 Montageanleitung

1.3.2 Area Change Control

By means of the outside handle contact and the inside handle contact it can be controlled
whether the lock has been operated in order to leave or to enter the room, as the contacts
switch at different moments. This can be evaluated by appropriate monitoring systems, e.g.
in order to control the number of persons in a room.
1.3.3 Operation in Connection with an Additional Escape Door
If unauthorized opening of the door from the inside has to be prevented or is to trigger an
alarm the effeff security lock 809 is particularly suitable to be used in connection with an
escape door control system. As usual the escape door control system is installed as an
additional locking system. Consequently the door can only be opened from the inside, if the
escape door control system has been released before.
The advantages of a combination of an escape door control system and an effeff security
lock 809 are:
•
It is not necessary to install a key switch on the outside of the door – This function can
be realized by means of the profile cylinder contact of the effeff security lock 809 in
upgraded version.
•
An additional access control system can control both security systems in parallel. The-
refore no further release of the door is necessary if the access code system is used.
•
Seen from outside the door is doubly secured, as it is locked by the escape door control
system and by the effeff security lock.
•
Authorized opening of the door from the outside by means of the key requires no additi-
onal devices and a „normal" operation like with any lock with key-operated latch bolt is
possible.
•
Seen from outside the door is still secured by the lock in the event of a power failure.
Exception: the version with controlled handles on both sides in fail-unlocked operation.
Combined triggering of an effeff security lock 809 and an escape door control system is
possible without problems and can be realized in different ways, if effeff escape door control
systems are used.
