Door locking devices
Door locking devices with and without a checking
device
The door locking devices from the AV series serve the
purpose of monitoring and interlocking of 1- and 2-leaf
lift landing doors. The safety locking devices fulfil the
requirements of the Lift Directive 95/16/EG and the
DIN EN 81-1 and -2.
There are var iations with die-cast enclosure as well
as thermoplastic enclosure, with one or two locking
elements, either in right- or left-hand versions, with
lever, pull strap or built-in blocks. The safety function
can be observed through the transparent cover. The
locking bolt has a travel of 22 mm, so that even after
the lowering of the door, the mandatory engagement
depth of 16 mm is safely maintained. The emergency
unlocking device can be operated externally with a
triangular key.
Function of the checking device
The European norm DIN EN 81-1, paragraph 7.7.5.1.
states: It shall not be possible, from positions normally
accessible to persons, to operate the lift with a landing
door open or unlocked, after one single action not
forming part of the normal operating sequence.
This requirement is fulfi lled by our door locking devices
with magnetic checking device, types AV 15, AV 20
and AV 25.
The checking device functions wi th two permanent
magnets, which with a closed door face one another
with like poles, repelling each other. The magnet of the
checking device is solidly connected to a locking piece,
moveable in its axial direction. Consequently, the
locking bolt is mechanically positively actuated to its
release, the locking means contact is closed and the
lift landing door is locked. On an opened lift landing
door, the magnets do not face each other. As a result,
the locking bolt is positively actuated and securely
locked. The locking means contact is open. In the case
of a fault (power failure), when the lift landing doors are
opened, the locking means contact remains safeguar-
ded from faulty locking and in the open position.

Installation instructions for door locking devices
with magnetic checking device
The inc lined section of the locking bolt allows the
required closing ability of the door as required by
DIN EN 81, paragraph 7.7.2.2. Corresponding to
the chosen engagement depth (12 or 21 mm), the
door edge must be rounded off to an edge length
of 30 mm in the area of the locking bolt or provided
with a fender or inclined section, if necessary.
The corresponding X- or Z- d imensions are tobe determined when ordering.

Condition of the door locking device with an
opened and unlocked landing door
With an opened landing door and a released locking
means cam, the locking bolt (2) is pulled back across
the angled lever (3) by pulling the pull strap (4) in
direction A or by rotating the roller lever in direction B
against the force of the spring (5). Consequently, the
locking means switch (7) is opened. The auxiliary
contact (8) is closed.
