Special functions II: Operation of the emergency exit control unit using electrical
security lock 809
The effeff electrical security lock 809 is a self-locking panic lock with electrically controllable external handle and
integrated monitoring and switching contacts.
An emergency exit security system with emergency exit control unit 720-30 or 720-32 can be combined with the
effeff electrical safety lock 809 (upgrade version with four monitoring contacts). This unit combination can be used
to implement a series of functions which are required particularly at outside doors in certain applications.
•
The closed door is always mechanically locked, as the electrical safety lock features a self-locking function
which automatically extends the bolt when the door is closed.
•
It is possible to pass through the door from the inside at any time, although this is monitored effectively by
the emergency exit security system.
•
The door can be passed through from the outside with a key without the use of an additional key-operated
switch. This function is initiated by the profile cylinder contact of the electrical safety lock.
•
For authorized pass-through from the outside or the inside, the door can be released by actuating a button.
This actuation process can be performed from a central release key, or from an access control system or
similar.
Passing through the door from the inside
Operation of a door fitted with this type of device
combination is not different from that of a normal door
equipped with an electrical emergency exit security
system.
As the internal handle of the electrical security
lock has a panic function, this direction through the
door is only controlled by the electrical emergency
exit security system. This must therefore initially be
unlocked by a suitable actuation process by the
emergency exit control unit, for example at the key-
operated switch of the door terminal or terminal
module, or released by a hazard warning alarm
(emergency button, fire alarm system etc.) before it is
possible to pass through the door.
Passing through the door from the
outside
The outer handle of the electrical security lock is
electrically controllable. Without being actuated, it is
in the idle mode, when actuated the dead bolt and
latch bolt remain locked and the door cannot be
opened.
By means of electrical actuation, the outer handle
of the electrical security lock is connected to the lock
mechanism and then has the same functional
characteristics as the internal handle. To be able to
pass through the door from the outside, this means
that both the electrical security lock has to be
actuated and the emergency exit control system
unlocked.
When the two control systems are combined,
these are interconnected in such a way that when the
emergency exit security system is unlocked, at the
same time the electrical security lock is actuated via
the emergency exit control device.
By means of a switching contact integrated in the
electrical security lock which is actuated by the profile
cylinder, on the other hand it is also possible to initiate
a temporary release of the emergency exit security
system. This allows the door to be passed through at
any time from the outside using a key. No additional
key-operated switch is required. If the door is opened
and closed again, it is secured by both systems
again, whereby the mechanical locked status is
retained even in case of a total failure of the energy
supply.
